Background

Ultrasound guidance is increasingly being used for neurolytic procedures that have traditionally been done with electrical stimulation (e-stim) guidance alone. Ultrasound visualization with e-stim?guided neurolysis can potentially allow adjustments in injection protocols that will reduce the volume of neurolytic agent needed to achieve clinical improvement.

Objective

This study compared e-stim only to e-stim with ultrasound guidance in phenol neurolysis of the musculocutaneous nerve (MCN) for elbow flexor spasticity. We also evaluated the ultrasound appearance of the MCN in this population.

Design

Retrospective review.

Setting

University hospital outpatient clinic.

Participants

Adults (N = 167) receiving phenol neurolysis to the MCN for treatment of elbow flexor spasticity between 1997 and 2014 and adult control subjects.

Methods

For each phenol injection of the MCN, the method of guidance, volume of phenol injected, technical success, improved range of motion at the elbow postinjection, adverse effects, reason for termination of injections, and details of concomitant botulinum toxin injection were recorded. The ultrasound appearance of the MCN, including nerve cross-sectional area and shape, were recorded and compared between groups.

Main Outcome Measures

The volume of phenol injected and MCN cross-sectional area and shape as demonstrated by ultrasound.

Results

The addition of ultrasound to e-stim?guided phenol neurolysis was associated with lower doses of phenol when compared to e-stim guidance alone (2.31 mL versus 3.69 mL, P < .001). With subsequent injections, the dose of phenol increased with e-stim guidance (P < .001), but not with e-stim and ultrasound guidance (P = .95). Both methods of guidance had high technical success, improved ROM at elbow postinjection, and low rates of adverse events. In comparing the ultrasound appearance of the MCN in patients with spasticity to that of normal controls, there was no difference in the cross-sectional area of the nerve, but there was more variability in shape.

Conclusions

Combined e-stim and ultrasound guidance during phenol neurolysis to the MCN allows a smaller volume of phenol to be used for equal effect, both at initial and repeat injection. The MCN shape was more variable in individuals with spasticity; this should be recognized so as to successfully locate the nerve to perform neurolysis.

Background

Spasticity is a common sequela of upper motor neuron pathology, such as cerebrovascular diseases and cerebral palsy. Intervention for spasticity of the ankle plantarflexors in physical therapy may include tone-inhibiting casting and/or orthoses for the ankle and foot. However, the physiological mechanism of tone reduction by such orthoses remains unclarified.

Objective

To investigate the electrophysiologic effects of tone-inhibiting insoles in stroke subjects with hemiparesis by measuring changes in reciprocal Ia inhibition (RI) in the ankle plantarflexor.

Design

An interventional before–after study.

Setting

Acute stroke unit or ambulatory rehabilitation clinic of a university hospital in Japan.

Participants

Ten subjects (47-84 years) with hemiparesis and 10 healthy male control subjects (31-59 years) were recruited.

Methods

RI of the spastic soleus in response to the electrical stimulation of the deep peroneal nerve was evaluated by stimulus-locked averaging of rectified electromyography (EMG) of the soleus while subjects were standing.

Main Outcome Measurements

The magnitude of RI, defined as the ratio of the lowest to the baseline amplitude of the rectified EMG at approximately 40 milliseconds after stimulation, was measured while subjects were standing with and without the tone-inhibiting insole on the hemiparesis side.

Results

Enhancement of EMG reduction with the tone-inhibiting insole was significant (P < .05) in the subjects with hemiparesis, whereas no significant changes were found in controls.

Conclusion

Tone-inhibiting insoles enhanced RI of the soleus in subjects after stroke, which might enhance standing stability by reducing unfavorable ankle plantarflexion tone.

Background

OnabotulinumtoxinA is approved for the treatment of upper and lower limb spasticity in adults. Guidance on common postures and onabotulinumtoxinA injection paradigms for upper limb spasticity has been developed via a Delphi Panel; however, similar guidance for lower limb spasticity has not been established.

Objective

To define a clinically recommended treatment paradigm for the use of onabotulinumtoxinA for each common posture among patients with poststroke lower limb spasticity (PSLLS) and to identify the most common PSLLS aggregate postures.

Design

Clinical experts provided insight regarding onabotulinumtoxinA treatment for PSLLS using an adaptation of the Delphi consensus process.

Setting

Delphi panel.

Participants

Ten expert clinicians in neurology and physical medicine and rehabilitation who treat PSLLS.

Methods

A minimum of 2 rounds of anonymous voting occurred for each recommendation until consensus was reached (≥66% agreement). The first round was conducted via a survey; the second round was an in-person meeting.

Main Outcome Measurements

Reached consensus on muscle selection for injection, overall and per-muscle dose of onabotulinumtoxinA, number of injection sites/muscle, onabotulinumtoxinA dilution, and use of localization techniques. The most common PSLLS postures were reviewed. Recommendations were tailored toward injectors with less experience.

Results

Consensus was reached on targeted subsets of muscles for each posture. Doses ranged from 20 to 150 U for individual muscles and 50 to 300 U for limb postures. OnabotulinumtoxinA dilution 50 U/mL (2:1 ratio) was considered most appropriate but varied based on muscles selected (range, 2:1-4:1). Experts agreed that localization techniques for muscle identification during injection for all postures would be useful. For suboptimal response to injection, all panel members would increase the dose, and the majority (89%) would increase the number of treated muscles. The panel identified 3 common aggregating lower limb postures: (1) equinovarus foot and flexed toes; (2) extended knee and plantar flexed foot/ankle; and (3) plantar flexed foot/ankle and flexed toes. The recommended starting doses for each aggregate posture were 400 U, 400 U, and 300 U, respectively.

Conclusion

The modified Delphi panel process provided consensus on common muscles and corresponding onabotulinumtoxinA treatment paradigms for postures associated with PSLLS that can be used for guidance in optimizing care delivery.

Background

AbobotulinumtoxinA has beneficial effects on spasticity and active movements in hemiparetic adults with upper limb spasticity (ULS). However, evidence-based information on optimal dosing for clinical use is limited.

Objective

To describe joint-specific dose effects of abobotulinumtoxinA in adults with ULS.

Design

Secondary analysis of a phase 3 study (NCT01313299).

Setting

Multicenter, international, double-blind, placebo-controlled clinical trial.

Participants

A total of 243 adults with ULS >6 months after stroke or traumatic brain injury, aged 52.8 (13.5) years and 64.3% male, randomized 1:1:1 to receive a single-injection cycle of placebo or abobotulinumtoxinA 500 U or 1000 U (total dose).

Methods

The overall effects of injected doses were assessed in the primary analysis, which showed improvement of angles of catch in finger, wrist, and elbow flexors and of active range of motion against these muscle groups. This secondary analysis was performed at each of the possible doses received by finger, wrist, and elbow flexors to establish possible dose effects.

Main Outcome Measures

Angle of arrest (XV1) and angle of catch (XV3) were assessed with the Tardieu Scale, and active range of motion (XA).

Results

At each muscle group level (finger, wrist, and elbow flexors) improvements in all outcome measures assessed (XV1, XV3, XA) were observed. In each muscle group, increases in abobotulinumtoxinA dose were associated with greater improvements in XV3 and XA, suggesting a dose-dependent effect.

Conclusions

Previous clinical trials have established the clinical efficacy of abobotulinumtoxinA by total dose only. The wide range of abobotulinumtoxinA doses per muscle groups used in this study allowed observation of dose-dependent improvements in spasticity and active movement. This information provides a basis for future abobotulinumtoxinA dosing recommendations for health care professionals based on treatment objectives and quantitative assessment of spasticity and active range of motion at individual joints.

Background

Spasticity is a common and potentially debilitating complication that develops after stroke, arising in approximately 30% of patients.

Objective

To evaluate the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in improving spasticity after stroke.

Design

Meta-analysis and systematic review.

Setting

Not applicable.

Patients

A total of 273 poststroke (hemorrhagic = 123, ischemic = 150) participants were included with sample sizes ranging from 5 to 80. The majority of participants were male (66.0%) with a mean age ranging from 55.0 to 64.6 years. Mean stroke duration ranged from 6 months to 10 years.

Methods

A literature search of multiple databases was conducted for articles published in English from January 1980 to April 2015 using select keywords. Studies were included if (1) the population included was >50% stroke patients; (2) the sample size included ≥4 subjects; (3) the intervention applied was rTMS; and (4) upper extremity spasticity was assessed pre- and postintervention. Randomized controlled trials (RCTs) were assessed for methodologic quality with the Physiotherapy Evidence Database tool. All research designs were given a level of evidence according to a modified Sackett Scale.

Main Outcome Measurements

Modified Ashworth Scale (MAS).

Results

Ten studies met the inclusion criteria: 2 RCTs (Physiotherapy Evidence Database scores 8-9) and 8 pre-post studies. Meta-analyses of primarily uncontrolled pre-post studies found significant improvements in MAS for elbow (P < .001), wrist (P < .001), and finger flexors (P < .001). However, a meta-analysis of the 2 available RCTs failed to find a significant rTMS treatment effect on MAS for the wrist (standardized difference = .34, P = .30).

Conclusions

There is limited available evidence to support the use of rTMS in improving spasticity poststroke. Despite the positive findings reported, better powered and appropriately controlled trials are necessary.

Background

Intra-articular corticosteroid injection is a commonly used therapy for adhesive capsulitis, but not enough studies exist on the optimal timing of the injection.

Objective

To determine whether intra-articular corticosteroid injection has better outcomes in patients with earlier stage than later stage of adhesive capsulitis.

Study Design

Retrospective longitudinal study

Setting

University-affiliated tertiary care hospital.

Participants

Primary adhesive capsulitis patients (n=339) who were unresponsive to at least 1 month of conservative treatment and who had ultrasound-guided corticosteroid injection.

Interventions

Not applicable.

Main Outcome Measurements

Visual analogue scale, Shoulder Pain and Disability Index, and passive range of motion (flexion, abduction, external rotation, and internal rotation and extension) were evaluated at pretreatment, month 1 and 12 after the first injection.

Results

The result of the multiple regressions, which considered the main and the interaction effect of confounding variables, showed that the differences of all outcomes in both short-term effect at month 1 and long-term effect at month 12 are greater when the duration of pain prior to injection is shorter. Among the confounders, the injection number in the difference of internal rotation and extension between month 0 and 12 (IRE Δ(0-12)) was statistically significant. IRE Δ(0-12) was also greater when the pain duration was shorter, though the decrease in IRE Δ(0-12) differed depending on the number of injections.

Conclusions

Early injection improves outcomes of adhesive capsulitis at both short- and long-term follow-ups. If pain persists despite non-invasive and conservative treatments, early injection may be considered to shorten its natural history.

Background

Poststroke distal lower limb spasticity impairs mobility, limiting activities of daily living and requiring additional caregiver time.

Objective

To evaluate the efficacy, safety, and sustained benefit of onabotulinumtoxinA in adults with poststroke lower limb spasticity (PSLLS).

Design

A multicenter, randomized, double-blind, phase 3, placebo-controlled trial (NCT01575054).

Setting

Sixty study centers across North America, Europe, Russia, the United Kingdom, and South Korea.

Patients

Adult patients (18-65 years of age) with PSLLS (Modified Ashworth Scale [MAS] ≥3) of the ankle plantar flexors and the most recent stroke ≥3 months before study enrollment.

Interventions

During the open-label phase, patients received ≤3 onabotulinumtoxinA treatments (≤400 U) or placebo at approximately 12-week intervals. Treatments were into the ankle plantar flexors (onabotulinumtoxinA 300 U into ankle plantar flexors; ≤100 U, optional lower limb muscles).

Main Outcome Measurements

The double-blind primary endpoint was MAS change from baseline (average score at weeks 4 and 6). Secondary measures included physician-assessed Clinical Global Impression of Change (CGI), MAS change from baseline in optional muscles, Goal Attainment Scale (GAS), and pain scale.

Results

Of 468 patients enrolled, 450 (96%) completed the double-blind phase and 413 (88%) completed the study. Small improvements in MAS observed with onabotulinumtoxinA during the double-blind phase (onabotulinumtoxinA, –0.8; placebo, –0.6, P = .01) were further enhanced with additional treatments through week 6 of the third open-label treatment cycle (onabotulinumtoxinA/onabotulinumtoxinA, –1.2; placebo/onabotulinumtoxinA, –1.4). Small improvements in CGI observed during the double-blind phase (onabotulinumtoxinA, 0.9; placebo, 0.7, P = .01) were also further enhanced through week 6 of the third open-label treatment cycle (onabotulinumtoxinA/onabotulinumtoxinA, 1.6; placebo/onabotulinumtoxinA, 1.6). Physician- and patient-assessed GAS scores improved with each subsequent treatment. No new safety signals emerged.

Conclusions

OnabotulinumtoxinA significantly improved ankle MAS, CGI, and GAS scores compared with placebo; improvements were consistent and increased with repeated treatments of onabotulinumtoxinA over 1 year in patients with PSLLS.

Background

Falls are a common adverse event among people with stroke. Previous studies investigating risk of falls after stroke have relied primarily on retrospective fall history ranging from 6-12 months recall, with inconsistent findings.

Objectives

To identify factors and balance assessment tools that are associated with number of falls in individuals with chronic stroke.

Design

Secondary analysis of a randomized clinical trial.

Setting

Multisite academic and clinical institutions.

Participants

Data from 181 participants with stroke (age 60.67 ± 11.77 years, post stroke 4.51 ± 4.78 years) were included.

Methods

Study participants completed baseline testing and were prospectively asked about falls. A multivariate negative binomial regression was used to identify baseline predictive factors predicting falls: age, endurance (6 minute walk test), number of medications, motor control (Fugl-Meyer lower extremity score), depression (Patient Health Questionnaire-9), physical activity (number of steps per week), and cognition (Mini Mental Status Exam score). A second negative binomial regression analysis was used to identify baseline balance assessment scores predicting falls: gait velocity (comfortable 10 Meter Walk), Berg Balance Scale (BBS), Timed Up and Go (TUG), and Functional Reach Test (FRT). Receiver operating characteristic (ROC) and area under the curve (AUC) were used to determine the cutoff scores for significant predictors of recurrent falls.

Main Outcome Measurement

The number of falls during the 42-week follow-up period.

Results

Baseline measures that significantly predicted the number of falls included increased number of medications, higher depression scores, and decreased FRT. Cutoff scores for the number of medications were 8.5 with an AUC of 0.68. Depression scores differentiated recurrent fallers at a threshold of 2.5 scores with an AUC of 0.62. FRT differentiated recurrent fallers at a threshold of 18.15 cm with an AUC of 0.66.

Conclusions

Number of medications, depression scores, and decreased FRT distance at baseline were associated with increased number of falls. Increased medications might indicate multiple comorbidities or polypharmacy effect; increased depression scores may indicate psychological status; and decreased functional reach distance could indicate dynamic balance impairments.

Background

Few studies have investigated the associations between patient-reported outcome and gait in patients with anterior cruciate ligament (ACL) injury and reconstruction over time. Because there is an association between ACL rupture and the presence of osteoarthritis later in life, a better understanding of these relationships will help to elucidate how patients’ gait pattern may affect pain and symptoms, potentially leading to better treatment for or preventing the development of knee OA.

Objective

To evaluate the associations between gait characteristics and self-reported pain and symptoms before, 6 months after, and 1 year after anterior cruciate ligament reconstruction.

Design

Prospective cohort study.

Setting

The Human Performance Center at the Orthopedic Institute at the University of California, San Francisco.

Patients

Patients with full unilateral ACL tears were enrolled. A total of 43 patients were included at 12 months postsurgery.

Methods

The independent variable in this study comprised specific gait variables in patients who had undergone ACL reconstruction. At each time point, 3-dimensional motion analysis was performed. Participants also completed the Knee Osteoarthritis Outcome Score (KOOS) questionnaire.

Main Outcomes Measurements

The primary study outcome measurement was the KOOS and was planned before data collection began. Partial correlations were used to examine cross-sectional associations between gait characteristics and KOOS pain and symptom scores at all time points. In addition, partial correlations were performed to examine the associations between change in postoperative KOOS from 6 months to 1 year and gait characteristics at baseline and 6 months.

Results

Significant associations between KOOS and gait characteristics were found at all time points, including an association between peak medial ground reaction force and pain (r = ?0.344, P = .02) and symptoms (r = ?0.407, P = .007) at baseline.

Conclusions

Specific gait variables may be predictive of greater pain and symptoms and less improvement over time postreconstruction. This could help to inform rehabilitation exercises post injury and pre reconstruction.

Background

Orthoses commonly are prescribed to children with cerebral palsy (CP) to provide foot correction and to improve ambulatory function. Immediate effects of ankle foot orthosis (AFOs) have been investigated, but long-term kinematic effects are lacking clinical evidence.

Objective

To determine changes in 3-dimensional ankle and foot segment motion in pediatric patients with CP between initial and follow-up visits (18-month average time differences) in both barefoot gait and gait with their AFO. We also investigated intravisit changes between barefoot and AFO gait.

Design

A prospective cohort study.

Setting

Children’s Hospital of Wisconsin, Department of Orthopaedic Surgery, Medical College of Wisconsin.

Patients

A total of 23 children with CP, mean age 10.5 years (6.2-18.1 years) were clinically prescribed either a solid ankle foot orthotic (SAFO), hinged ankle foot orthotic (HAFO), or supramalleolar orthotic.

Methods

Holes were cut in the study orthoses so that electromagnetic markers could be directly placed on the skin. A 6-foot segment model was used.

Outcome Measurements

Kinematic and kinetic data were recorded for each patient’s initial and follow-up visit (18-month follow-up average, 15-20 months range).

Results

For the SAFO group (gait with AFO), a significant decrease in dorsiflexion was found between the initial and third visit (P = .008). Furthermore, the SAFO group (barefoot gait) had an increased eversion at the midfoot for most of the gait cycle (P < .008). Sagittal forefoot range of motion was reduced for all 3 groups between the barefoot and AFO groups.

Conclusion

The use of AFOs long term either maintained or improved foot deformities or dysfunction.

Background

Home-based therapy optimizing biomechanics and neuromuscular control is increasingly recognized as a treatment option for chronic nonspecific low back pain (CNSLBP). However, its impact on pain, function, and gait is limited among patients in a metropolitan area.

Objective

To evaluate the change of pain, function, and gait parameters with home-based therapy with the use of footwear-generated biomechanical manipulation and perturbation training in a population with CNSLBP in a metropolitan area.

Design

Prospective observational study.

Setting

Outpatient rehabilitation clinic at an academic teaching hospital.

Participants

One hundred sixteen patients with CNSLBP for more than 6 months.

Intervention

Six months of home-based therapy with a biomechanical device using 4 modular elements attached to a foot-worn platform.

Main Outcome Measures

Instrumental gait analysis (gait velocity, step length, single limb support phase % of gait cycle), Numeric Rating Scale for pain, and Oswestry Disability Questionnaire Index for pain and function.

Results

Only 43 patients (37.1%) completed the study. Among 43 patients, mean gait velocity increased from 86.6 ± 20.7 to 99.7 ± 22.1 cm/s (P < .0001) in 6 months. Mean left step length increased from 51.1 ± 8.4 to 54.8 ± 9.8 cm (P < .0001). Mean right step length increased from 51.0 ± 7.9 to 55.4 ± 9.0 cm (P < .0001). Mean single limb support increased from 36.4 ± 2.8 to 37.2 ± 2.5%, (P = .208) in the right side and from 36.6 ± 3.0 to 37.8 ± 4.4%, (P = .019) in the left side. Median Oswestry Disability Questionnaire Index score improved from 28 (18-44; interquartile range) to 17 (10-35) (P = .045). Mean Numeric Rating Scale for back pain improved from 7.7 ± 1.8 to 3.3 ± 3.1 (P < .0001).

Conclusion

At 6 months, patients with CNSLBP undergoing home-based therapy with footwear-generated biomechanical manipulation and perturbation training demonstrated significant improvement of objective gait parameters, pain, and function.

Background

Stroke is a primary cause of death and disability in upper-middle–income countries such as Colombia. Given the lack of comprehensive rehabilitation for stroke patients in Colombia, there is a need to assess longitudinal mental health problems poststroke in this region.

Objective

To compare the course of mental health in stroke patients to healthy controls over the first year poststroke in Ibague, Colombia.

Design

Cross-sectional study.

Setting

The Psychological Attention Center of Antonio Nariño University in Ibague, Colombia.

Participants

Stroke patients (n = 50) and age- and gender-matched healthy controls (n = 50).

Methods

Patients and controls completed self-report Spanish versions of demographic information, injury-related characteristics, and mental health questionnaires

Main Outcome Measurements

Outcomes assessed included mental health (depression, anxiety, and stress) at 3, 6, and 12 months poststroke.

Results

Hierarchical linear models suggested that stroke patients had worse depression and anxiety over time than controls (P < .001). Among patients, depression and anxiety decreased over time (P < .001), whereas stress increased over time (P < .01). The findings suggest that although anxiety and depression improved over time in stroke patients, their mental health remained significantly lower than that of controls.

Conclusions

This is the first study to examine the course of mental health over the first year poststroke in Latin America, specifically in Ibague, Colombia. Despite the improvements in anxiety and depression over the first year poststroke, patient anxiety and depression were still worse in comparison to those in healthy controls. The current findings indicate a need for rehabilitation services in Colombia, especially targeting mental health issues.

Background

Shoulder dysfunction is common in persons with spinal cord injury (SCI) with an incidence of up to 63%. Dysfunction is a result of muscle imbalances, specifically denervated rotator cuff muscles that are repetitively used during manual wheelchair propulsion.

Objective

To determine which arm stroke technique, pump (P) or semicircular (SC), is most energy efficient for long periods of propulsion.

Design

A randomized study with repeated measures observations.

Setting

The study was performed at an institutional gait analysis laboratory.

Participants

18 able-bodied (AB) male participants were studied and randomized into one of 2 conditions, SC or P.

Methods

Shoulder muscle fatigue was measured by changes in Borg CR10 Rate of Perceived Exertion (Borg RPE) and upper extremity strength via a handheld dynamometer. Participants were studied and assigned into one of 2 conditions of wheelchair arm propulsion patterns, SC or P group, and propelled on a wheelchair treadmill for 10 minutes.

Main Outcome Measures

The primary outcomes included recordings of Borg RPE scale during continuous wheelchair propulsion and pre- and post-test dynamometer testing means for bilateral elbow and shoulder extension. Analysis of covariance, t-tests, and Kruskal-Wallis tests were used in analyzing data.

Results

Although not significant (P = .23), the Borg RPE scores for the SC condition were consistently higher than the scores for the P condition. In addition, the dynamometer pre- and post-test readings demonstrated a larger decrease for the SC condition participants than for the P condition participants, but were not statistically significant.

Conclusions

These data demonstrate that the SC wheelchair propulsion pattern appears to be more fatiguing to shoulder muscles than the P propulsion pattern. However, more data would need to be collected to find a significant difference.

Background

The presence of subtle losses in hand dexterity after stroke affects the regaining of independence with regard to activities of daily living. Therefore, awareness of ipsilesional upper extremity (UE) function may be of importance when developing a comprehensive rehabilitation program. However, current hand function tests seem to be unable to identify asymptomatic UE impairments.

Objectives

To assess the motor coordination as well as the sensory perception of an ipsilesional UE using biomechanical analysis of performance-oriented tasks and conducting a Manual Tactile Test (MTT).

Design

Case-controlled study.

Setting

A university hospital.

Participants

A total of 21 patients with unilateral stroke, along with 21 matched healthy control subjects, were recruited.

Methods

Each participant was requested to perform a pinch?holding-up activity (PHUA) test, object-transport task, and reach-to-grasp task via motion capture, as well as the MTT.

Main Outcome Measurements

The kinetic data of the PHUA test, kinematics analysis of functional movements, and time requirement of MTT were analyzed.

Results

Patients with ipsilesional UE had an inferior ability to scale and produce pinch force precisely when conducting the PHUA test compared to the healthy controls (P < .05). The movement time was statistically longer and peak velocity was significantly lower (P < .05) in the performance-oriented tasks for the ipsilesional UE patients. The longer time requirement in 3 MTT subtests showed that the ipsilesional UE patients experienced degradation in sensory perception (P < .001).

Conclusion

Comprehensive sensorimotor assessments based on functional perspectives are valid tools to determine deficits in the sensation-perception-motor system in the ipsilesional UE. Integration of sensorimotor training programs for ipsilesional UE in future neuro-rehabilitation strategies may provide more beneficial effects to regain patients’ motor recovery and to promote daily living activity independence than focusing on paretic arm motor training alone.

Background

Pharmacogenomic variability can contribute to differences in pharmacokinetics and clinical responses. Pediatric patients with cerebral palsy with genetic variations have not been studied for these potential differences.

Objective

To determine the genetic sources of variation in oral baclofen clearance and clinical responses.

Design

Pharmacogenomic add-on study to determine variability in oral baclofen clearance and clinical responses.

Setting

Multicenter study based in academic pediatric cerebral palsy clinics.

Participants

A total of 49 patients with cerebral palsy who had participated in an oral baclofen pharmacokinetic/pharmacodynamic study.

Methods or Interventions

Of 53 participants in a pharmacokinetic/pharmacodynamic trial, 49 underwent genetic analysis of 307 key genes and 4535 single-nucleotide polymorphisms involved in drug absorption, distribution, metabolism, and excretion. Associations between genotypes and phenotypes of baclofen disposition (weight-corrected and allometrically scaled clearance) and clinical endpoints (improvement from baseline in mean hamstring Modified Tardieu Scale scores from baseline for improvement of R1 spastic catch) were determined by univariate analysis with correction for multiple testing by false discovery rate.

Main Outcome Measurements

Primary outcome measures were the genotypic and phenotypic variability of oral baclofen in allometrically scaled clearance and change in the Modified Tardieu Scale angle compared to baseline.

Results

After univariate analysis of the data, the SNP of ABCC9 (rs11046232, heterozygous AT versus the reference TT genotype) was associated with a 2-fold increase in oral baclofen clearance (mean 0.51 ± standard deviation 0.05 L/h/kg for the AT genotype versus 0.25 ± 0.07 L/h/kg for the TT genotype, adjusted P < .001). Clinical responses were associated with decreased spasticity by Modified Tardieu Scale in allelic variants with SNPs ABCC12, SLC28A1, and PPARD.

Conclusions

Genetic variation in ABCC9 affecting oral baclofen clearance highlights the need for continued studies of genetic polymorphisms to better characterize variable drug response in children with cerebral palsy. Single-nucleotide polymorphisms in ABCC12, SLC28A1, and PPARD were associated with varied responses, which warrants further investigation to determine their effect on spasticity.

Background

Functional movement disorders (FMDs) are conditions of abnormal motor control thought to be caused by psychological factors. These disorders are commonly seen in neurologic practice, and prognosis is often poor. No consensus treatment guidelines have been established; however, the role of physical therapy in addition to psychotherapy has increasingly been recognized. This study reports patient outcomes from a multidisciplinary FMD treatment program using motor retraining (MoRe) strategies.

Objective

To assess outcomes of FMD patients undergoing a multidisciplinary treatment program and determine factors predictive of treatment success.

Design

Retrospective chart review.

Setting

University-affiliated rehabilitation institute.

Patients

Thirty-two consecutive FMD patients admitted to the MoRe program from July 2014–July 2016.

Intervention

Patients participated in a 1-week, multidisciplinary inpatient treatment program with daily physical, occupational, speech therapy, and psychotherapy interventions.

Main Outcome Measurements

Primary outcome measures were changes in the patient-rated Clinical Global Impression Scale (CGI) and the physician-rated Psychogenic Movement Disorder Rating Scale (PMDRS) based on review of standardized patient videos. Measurements were taken as part of the clinical evaluation of the program.

Results

Twenty-four of the 32 patients were female with a mean age of 49.1 (±14.2) years and mean symptom duration of 7.4 (±10.8) years. Most common movement phenomenologies were abnormal gait (31.2%), hyperkinetic movements (31.2%), and dystonia (31.2%). At discharge, 86.7% of patients reported symptom improvement on the CGI, and self-reported improvement was maintained in 69.2% at the 6-month follow-up. PMDRS scores improved by 59.1% from baseline to discharge. Longer duration of symptoms, history of abuse, and comorbid psychiatric disorders were not significant predictors of treatment outcomes.

Conclusions

The majority of FMD patients experienced improvement from a 1-week multidisciplinary inpatient rehabilitation program. Treatment outcomes were not negatively correlated with longer disease duration or psychiatric comorbidities. The results from our study are encouraging, although further long-term prospective randomized studies are needed.

Setting

We assessed examination results from the 2015 ABPMR-CE-1.

Participants

A total of 489 deidentified candidates taking the 2015 ABPMR-CE-1.

Methods

A 1-parameter Item Response Theory (IRT) measurement model was utilized. A Principal Components Analysis (PCA) of standardized residual correlations was used to detect multidimensionality.

Main Outcome Measure

Results

The results of the dimensionality analysis indicated that the ABPMR-CE-1 examination is highly unidimensional from a psychometric perspective. Expert content review of the substantive content of small contrasting clusters of questions provided additional assurance of the unidimensional nature of the examination.

Conclusions

The ABPMR-CE-1 appears indeed to measure a single construct, which suggests a sound structure of the examination. It closely approximates the assumption of statistical unidimensionality.

Background

Lumbar facet arthropathy is a common cause of low back pain. Literature supports treatment with radiofrequency ablation (RFA) of associated nerves that innervate lumbar facets when alternative conservative therapies have failed. Diagnostic local anesthetic blocks precede therapeutic ablation, but have a false-positive rate of 27%-63%, and some authors have questioned their utility in predicting therapeutic response to RFA. The authors of the current study believe that injectate volume may be a contributing factor to false positivity.

Objective

To evaluate the difference in volume dispersion between 0.25 mL and 0.5 mL of injectate when performing lumbar medial branch blocks. We hypothesized that injection volumes greater than 0.25 mL during lumbar medial branch blocks would affect the distal branches of the adjacent medial branches, thus decreasing the specificity of the procedure. Thus, we attempted to demonstrate that injection volumes greater than 0.25 mL during lumbar medial branch blocks would affect the distal branches of the adjacent medial branches, which might increase false positivity of the blocks.

Study Design

Cadaveric investigation.

Setting

Tertiary care center.

Participants

Not applicable.

Outcome Measurements

To demonstrate that the spread of lumbar medial branch blocks using commonly injected volume coats adjacent structures that are not affected by radiofrequency ablation.

Methods

Six cadavers were chosen with nondissected lumbar spines. Fluoroscopically guided medial branch injections were performed bilaterally using the posterior oblique approach. A volume of 0.25 mL or 0.50 mL of a 9:1 solution of Omnipaque 240 and 1% medical grade methylene blue were delivered to the left and right sides, respectively. Postinjection computed tomographic imaging was performed, followed by dissection.

Results

Both volumes adequately coated the medial branches, but in the 0.5-mL injectate cohort there was consistent spread dorsally to the superficial muscles and distal segments of the dorsal branches distant to the target nerves, whereas in the 0.25-mL injectate cohort the spread was contained in the deep and intermediate muscular lumbar layers, close to the intended target.

Conclusion

We suggest that a 0.5-mL injectate volume in clinical practice may produce an adjacent-level nerve block in addition to the intended injection level, thus decreasing the specificity of a targeted lumbar medial branch block. A 0.25-mL quantity of injectate reliably contacted the lumbar medial branches without extensive extravasation. Presumably, this means that 0.25 mL total volume for a lumbar medial branch block may provide greater specificity for RFA planning.

Background

Bone marrow aspirate concentrate (BMC) is one of the few cell-based therapies available as a possible biological treatment for early osteoarthritis (OA). Its efficacy, safety, and benefit compared with other treatments are still to be determined.

Objective

To assess the clinical outcomes of patients undergoing intra-articular injection of BMC for the treatment of early knee and hip OA.

Design

Prospective, cohort study.

Setting

Single institution, quaternary level of care.

Patients

Nineteen patients (16 female and 3 male), totaling 25 joints (10 knees, 15 hips), treated with intra-articular BMC for early OA between 2014 and 2016. The mean age at time of the procedure was 58 ± 12.7 years (range, 30-80 years). The mean follow-up was 13.2 ± 6.3 months (range, 6-24 months). Inclusion criteria included ≥18 years; knee OA, Kellgren–Lawrence grade I-II; hip OA, Tönnis grade I-II; first-time intra-articular BMC therapy, after unsuccessful symptomatic and conservative treatments (ie, physical therapy, analgesics and anti-inflammatory drugs) for 6 months. Exclusion criteria included pregnancy; malignancy; rheumatologic diseases; infection; Kellgren–Lawrence grade III-IV; Tönnis grade III; and previous intra-articular injections or surgery.

Interventions

All patients had autologous bone marrow aspirate harvested from the iliac crest and centrifuged to achieve BMC, for intra-articular injection.

Main Outcome Measurements

The hypothesis was formulated before the study. Patient-reported outcomes measures were assessed preoperatively and at last follow-up using the Western Ontario and McMaster Universities Arthritis Index.

Results

Western Ontario and McMaster Universities Arthritis Index improved from a baseline of 40.8 ± 18.3% to 20.6 ± 17% (P < .001) at final follow-up. The satisfaction rate was 63.2%. The minimal clinically important difference threshold of 9.15 points was reached by 64% of the patients. Two patients were converted to total hip arthroplasty at 8 months after BMC injection.

Conclusions

Intra-articular injections of BMC for the treatment of early knee or hip OA were safe and demonstrated satisfactory results in 63.2% of patients. Future studies are necessary to determine the efficacy of this technique and its safety profile.

Background

There is a growing interest in the use of biologic agents such as platelet-rich plasma and mesenchymal stem/stromal cells to treat musculoskeletal injuries, including meniscal tears. Although previous research has documented the role of diagnostic ultrasound to evaluate meniscal tears, sonographically guided (SG) techniques to specifically deliver therapeutic agents into the meniscus have not been described.

Objective

To describe and validate SG injection techniques for the body and posterior horn of the medial and lateral meniscus.

Design

Prospective, cadaveric laboratory investigation.

Setting

Academic institution procedural skills laboratory.

Subjects

Five unenbalmed cadaveric knee-ankle-foot specimens from 5 donors (3 female and 2 male) ages 33-92 years (mean age 74 years) with body mass indices of 21.1-32.4 kg/m2 (mean 24.1 kg/m2).

Methods

A single, experienced operator completed SG injections into the bodies and posterior horns of the medial and lateral menisci of 5 unenbalmed cadaveric knees using colored latex and a 22-gauge, 38-mm needle. After injection, coinvestigators dissected each specimen to assess latex distribution within the menisci and identify injury to intra-articular and periarticular structures.

Main Outcome Measures

Latex location within the target region of meniscus (accurate/inaccurate), and iatrogenic injury to “at risk” intra- and periarticular structures (present/absent).

Results

Seventeen of 20 injections were accurate. Two of 3 inaccurate injections infiltrated the posterior horn of the medial meniscus instead of the targeted meniscal body. One inaccurate lateral meniscus injection did not contain latex despite sonographically accurate needle placement. No specimen exhibited injury to regional neurovascular structures or intra-articular hyaline cartilage.

Conclusions

SG meniscus injections are feasible and can accurately and safely deliver injectates such as regenerative agents into bodies and posterior horns of the medial and lateral menisci. The role of SG intrameniscal injections in the treatment of patients with degenerative and traumatic meniscal disorders warrants further exploration.
