Background

Depression and traumatic brain injury (TBI) substantially contribute to the U.S. health care burden. Depression is a known risk factor for prolonged recovery after TBI. However, the effect of depression treatment on health care utilization has yet to be studied.

Objective

To examine whether an association exists between pharmacologic treatment of depression at the time of mild or concussive TBI and the number of subsequent clinician visits for persistent injury-related symptoms.

Design

Retrospective medical record review.

Setting

Tertiary care medical center.

Participants

A total of 120 patients (mean age 45.6 years) with a history of depression who subsequently experienced a mild or concussive TBI were included.

Methods

Individuals were identified with co-occurring diagnoses of depression and mild or concussive TBI by retrospective electronic medical record review. The diagnosis of depression must have preceded the diagnosis of TBI.

Main Outcome

The number of clinician visits for postinjury symptoms were counted at 3, 6, and 12 months postinjury.

Results

Clinician visits for persistent injury-related symptoms were significantly fewer at all 3 time points for the group treated for depression at time of injury.

Conclusions

Depressed individuals who were pharmacologically treated for depression at the time of TBI had significantly fewer clinician visits for persistent postinjury symptoms than those not pharmacologically treated for depression at the time of injury. Routine depression screening in patients with a high risk for TBI may identify a mood disorder that could contribute to persistent symptoms if left untreated, with its effective management potentially reducing health-related costs.

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.

Objective

To characterize behavioral and health outcomes in veterans with traumatic brain injury (TBI) acquired in nondeployment and deployment settings.

Design

Cross-sectional assessment evaluating TBI acquired during and outside of deployment, mental and behavioral health symptoms, and diagnoses.

Setting

Veterans Affairs Medical Centers.

Participants

Iraq and Afghanistan veterans who were deployed to a warzone (N=1399).

Interventions

Not applicable.

Main Outcome Measures

Comprehensive lifetime TBI interview, Structured Clinical Interview for DSM-IV Disorders, Combat Exposure Scale, and behavioral and health measures.

Results

There was a main effect of deployment TBI on depressive symptoms, posttraumatic stress symptoms, poor sleep quality, substance use, and pain. Veterans with deployment TBI were also more likely to have a diagnosis of bipolar, major depressive, alcohol use, and posttraumatic stress disorders than those who did not have a deployment TBI.

Conclusions

TBIs acquired during deployment are associated with different behavioral and health outcomes than TBI acquired in nondeployment environments. The presence of TBI during deployment is associated with poorer behavioral outcomes, as well as a greater lifetime prevalence of behavioral and health problems in contrast to veterans without deployment TBI. These results indicate that problems may persist chronically after a deployment TBI and should be considered when providing care for veterans. Veterans with deployment TBI may require treatment alterations to improve engagement and outcomes.  相似文献

Background

Mild traumatic brain injury (mTBI) can have long-term cognitive and functional consequences, and recent mTBI has been associated with impaired performance on measures related to driving ability. However, it remains unclear whether mTBI history is associated with poorer driving performance.

Objective

To examine the longer-term effects of mTBI on self-reported driving ability.

Design

Retrospective cross-sectional study.

Setting

Online.

Participants

Three hundred eighty-nine participants (169 who reported an mTBI history and 220 without an mTBI history).

Intervention

Comparing participants who report a history of mTBI with those who do not report a history of mTBI.

Outcomes

Self-report measures of mTBI history, frequency of aberrant driving behaviors, recent history of car accidents and citations, and previous psychological diagnoses and current symptoms.

Results

Participants with a history of mTBI reported an overall higher frequency of aberrant driving behaviors and committing more driving violations that risked the safety of others than comparison participants. Participants with mTBI also were more likely to have been involved in a car accident within the past 6 months and the past 3 years. Of participants with mTBI, reports of driving violations decreased with longer time since the most recent injury. Driving violations and crash risk also decreased with increased age and years of driving experience.

Conclusions

Individuals with a history of mTBI are more likely to deliberately drive in a manner that risks the safety of others and are at a heightened risk of being involved in a recent car crash. Future work should examine predictor variables in greater depth and incorporate performance-based measures of driving ability to further explore these topics.

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

Ideally, high-stakes examinations assess 1 dimension of medical knowledge to produce precise estimates of a candidate’s performance. It has not been reported whether the American Board of Physical Medicine and Rehabilitation Part 1 Certification Examination (ABPMR-CE-1) is unidimensional or not.

Objective

To examine the ABPMR-CE-1 to measure how many dimensions it assesses.

Design

Retrospective observational study.

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

Number of primary dimensions reflected in the 325 test questions.

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

Ultrasound is rarely used for guiding lumbosacral epidural steroid injections due to its technical limitations. For example, sonographic imaging lacks the ability to confirm epidural spread and identify vascular uptake. The perceived risk that these limitations pose to human subjects has precluded any large scale clinical trials to date.

Objective

To compare the accuracy of ultrasound versus fluoroscopic guidance for first sacral transforaminal epidural injections.

Design

Cadaveric comparative study using dichotomous outcomes.

Setting

A fluoroscopy suite and anatomic laboratory at an academic medical center.

Subjects

Four unembalmed adult human cadavers with no history of spinal surgery.

Methods

Eight sites were injected twice by one interventionalist, using fluoroscopic and ultrasound guidance. In the fluoroscopy arm, contrast spread was assessed using computed tomography. In the ultrasound arm, latex spread was assessed using gross anatomic dissection. Any visible evidence of epidural spread constituted a positive result.

Main Outcome Measurements

Comparison of the success of obtaining epidural contrast flow was the primary outcome measure. Secondary outcome measures included average duration, rate of intravascular uptake, and quantity of intravascular uptake.

Results

All injections performed in both the ultrasound arm and the fluoroscopy arm had positive epidural spread. The average duration was 3.03 minutes with fluoroscopy and 4.76 minutes with ultrasound. The rate of intravascular uptake was 37.5% with fluoroscopy and 50% with ultrasound. Within the ultrasound arm, greater intravascular spread and duration variability were recorded.

Conclusion

Although ultrasonography can provide reliable image guidance for cannulating the first sacral foramen in cadavers, it would have limited clinical utility due to its inability to visualize relevant neurovascular structures deep to the osseus roof and exclude intravascular uptake.

Background

The incidence of contact isolation for multidrug-resistant organisms is increasing in acute hospitals and inpatient rehabilitation units alike. There is limited evidence on the effect of contact isolation on functional outcomes during inpatient rehabilitation.

Objective

To determine whether the use of a modified contact isolation protocol (MCI) resulted in noninferior functional outcomes compared with children without contact isolation (NCI) on inpatient rehabilitation.

Design

This is a retrospective noninferiority study.

Setting

One academically affiliated pediatric inpatient rehabilitation unit located in a children’s hospital.

Patients

All children with any diagnosis admitted to inpatient rehabilitation from January 1, 2007, to December 31, 2014.

Methods or Interventions

We compared functional outcomes for 2 groups of children.

Main Outcome Measurements

Primary outcome measures included the Functional Independence Measure for Children (WeeFIM) efficiency and the change in the Developmental Functional Quotient (DFQ) for the WeeFIM. Noninferiority margins of 0.63 for the WeeFIM efficiency and 0.092 for the change in DFQ for the WeeFIM were used.

Results

There were a total of 949 patients of whom 899 were NCI, 48 MCI, and 2 excluded due to missing information. Patients with MCI had functional outcomes that were noninferior to those with NCI including the WeeFIM efficiency (mean difference 0.002, 95% CI –0.38 to 0.404) and the change in DFQ for the WeeFIM (mean difference –0.05, 95% CI –0.058 to 0.003).

Conclusions

The modified contact isolation protocol, having resulted in noninferior functional outcomes in inpatient rehabilitation may provide adequate contact isolation while allowing for noninferior functional outcomes. This may be a guide in the face of an ever-increasing need for contact isolation.

Background

Critical illness polyneuromyopathy (CIPNM) increasingly is recognized as a source of disability in patients requiring intensive care unit (ICU) admission. The prevalence and impact of CIPNM on patients in the rehabilitation setting has not been established.

Objectives

To determine the proportion of at-risk rehabilitation inpatients with evidence of CIPNM and the functional sequelae of this disorder.

Design

Prospective observational study.

Setting

Tertiary academic rehabilitation hospital.

Patients

Rehabilitation inpatients with a history of ICU admission for at least 72 hours.

Methods

Electrodiagnostic studies were performed to evaluate for axonal neuropathy and/or myopathy in at least one upper and one lower limb.

Main Outcome Measurements

The primary outcome was prevalence of CIPNM. Secondary outcomes included Functional Independence Measure (FIM) scores, rehabilitation length of stay (RLOS), and discharge disposition.

Results

A total of 33 participants were enrolled; 70% had evidence of CIPNM. Admission FIM score, discharge FIM, FIM gain, and FIM efficiency were 64.1, 89.9, 25.5, and 0.31 in those with CIPNM versus 78.4, 94.6, 16.1, and 0.33 in those without CIPNM, respectively. Average RLOS was 123 days versus 76 days and discharge to home was 57% versus 90% in the CIPNM and non-CIPNM groups, respectively.

Conclusions

CIPNM is very common in rehabilitation inpatients with a history of ICU admission. It was associated with a lower functional status at rehabilitation admission, but functional improvement was at a similar rate to those without CIPNM. Longer RLOS stay may be required to achieve the same functional level.

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

There are no guidelines on the ideal time to inject botulinum toxin type A (BT-A) for lower leg spasticity in stroke patients. An early injection may produce unwanted weakness, interfering with gait recovery.

Objective

To evaluate whether the outcomes after BT-A injection for plantarflexion spasticity can be different according to stroke chronicity.

Design

A secondary analysis study from a double-blinded, randomized trial with group reclassification according to stroke chronicity.

Setting

Two rehabilitation centers.

Participants

Stroke participants (n = 40) with plantar flexor spasticity, treated with BT-A (200 units) into the gastrocnemius muscle.

Methods

Outcome parameters were reanalyzed serially using 2-way repeated measures of analysis of variance (ANOVA), at baseline and 2, 4, and 8 weeks postinjection. Subjects were reclassified into 3 groups: early, within 6 months (n = 12); middle, between 6 months and 1 year (n = 14); and late, between 1 and 2 years from stroke onset (n = 12).

Main Outcome Measures

The Modified Ashworth Scale, clonus scale, 10-m walking test, ABILOCO, and the Functional Ambulation Category.

Results

The 2-way repeated measures of ANOVA showed improvement in gait and spasticity after injection in the 3 groups. Significant improvement in the Modified Ashworth Scale (P < .001) was observed, starting from the post–2 week injection period. Improvement of gait as assessed by the functional measurement ABILOCO and the Functional Ambulation Category (P < .001) were observed in all 3 groups, mostly at the post–8 week injection period.

Conclusions

Our serial measurements of the outcome parameters indicated that BT-A could be expected to lead to consistent improvement in both the muscle tone and gait quality in those with plantar flexor spasticity regardless of stroke chronicity, including those injected as early as within the first 6 months.

Background

Lumbar spondylolysis is a defect in the pars interarticularis that is common in young athletes; the stress distribution at the pars interarticularis is the highest in extension and rotation movements. The paraspinal muscles play an important role in stabilization of the lumbar spine; however, no study has assessed the properties of paraspinal muscles in athletes with lumbar spondylolysis.

Objective

To evaluate the properties of paraspinal muscles in athletes with lumbar spondylolysis.

Design

Cross-sectional study.

Setting

Laboratory.

Participants

Six high school baseball players with terminal-stage lumbar spondylolysis and 11 high school baseball players without organic lumbar lesions of similar anthropometric characteristics.

Methods

All subjects performed the unsupported trunk holding test combined with surface electromyographic (EMG) power spectral analysis until exhaustion. The results of EMG power spectral analysis were compared between the spondylolysis and control groups.

Main Outcome Measurements

The median frequency (MF) was computed from the raw EMG signal of the erector spinae and multifidus during trunk holding test using fast Fourier transform spectrum analysis. The initial MF and MF slope were calculated.

Results

No significant differences in endurance time were found between the spondylolysis and control groups. The initial MF and the MF slopes of the erector spinae and multifidus were significantly lower in the spondylolysis group than in the control group.

Conclusions

The results suggest lower fast-twitch motor unit recruitment in the erector spinae and multifidus of high school baseball players with terminal-stage lumbar spondylolysis compared with the control.

Background

Dextromethorphan 20 mg / quinidine 10 mg (DM/Q) was approved to treat pseudobulbar affect (PBA) based on phase 3 trials conducted in participants with amyotrophic lateral sclerosis or multiple sclerosis. PRISM II evaluated DM/Q effectiveness, safety, and tolerability for PBA following stroke, dementia, or traumatic brain injury (TBI).

Objective

To report results from the TBI cohort of PRISM II, including a TBI-specific functional scale.

Design

Open-label trial evaluating twice-daily DM/Q over 90 days.

Study Participants

Adults (n = 120) with a clinical diagnosis of PBA secondary to nonpenetrating TBI; stable psychiatric medications were allowed.

Methods

PRISM II was an open-label, 12-week trial enrolling adults with PBA secondary to dementia, stroke, or TBI (NCT01799941). All study participants received DM/Q 20/10 mg twice daily. Study visits occurred at baseline and at day 30 and day 90.

Setting

150 U.S. centers.

Main Outcome Measurements

Primary endpoint was change in Center for Neurologic Study–Lability Scale (CNS-LS) score from baseline to day 90. Secondary outcomes included PBA episode count, Clinical and Patient Global Impression of Change (CGI-C; PGI-C), Quality of Life–Visual Analog Scale (QOL-VAS), treatment satisfaction, Neurobehavioral Functioning Inventory (NFI), Patient Health Questionnaire (PHQ-9), and Mini Mental State Examination (MMSE).

Results

DM/Q-treated participants showed significant mean (SD) reductions in CNS-LS from baseline (day 30, –5.6 [5.2]; day 90, –8.5 [5.2]; both, P<.001). Compared with baseline, PBA episodes were reduced by 61.3% and 78.5% at days 30 and 90 (both, P<.001). At day 90, 78% and 73% of study participants had “much improved” or “very much improved” on the CGI-C and PGI-C. QOL-VAS scores were significantly reduced from baseline (–3.7 [3.3], P<.001). Mean (SD) PHQ-9 scores improved compared to baseline at day 30 (–3.2 [5.3], P<.001) and 90 (–5.2 [6.4], P<.001). NFI T scores were significantly improved (P<.001), whereas MMSE scores were unchanged. Adverse events (AEs) were consistent with the known DM/Q safety profile; the most common AE was diarrhea (8.3%).

Conclusions

DM/Q was well tolerated, and it significantly reduced PBA episodes in study participants with TBI. Changes in CNS-LS and PBA episode count were similar to changes with DM/Q in phase 3 trials.

Background

A timely return to competitive sport is a primary goal of anterior cruciate ligament reconstruction (ACLR). It is not known whether an accelerated return to sport increases the risk of early-onset knee osteoarthritis (KOA).

Objective

To determine whether an accelerated return to sport post-ACLR (ie, <10 months) is associated with increased odds of early KOA features on magnetic resonance imaging (MRI) 1 year after surgery and to evaluate the relationship between an accelerated return to sport and early KOA features stratified by type of ACL injury (isolated or concurrent chondral/meniscal injury) and lower limb function (good or poor).

Design

Cross-sectional study.

Setting

Private radiology clinic and university laboratory.

Participants

A total of 111 participants (71 male; mean age 30 ± 8 years) 1-year post-ACLR.

Methods

Participants completed a self-report questionnaire regarding postoperative return-to-sport data (specific sport, postoperative month first returned), and isotropic 3-T MRI scans were obtained.

Outcome Measures

Early KOA features (bone marrow, cartilage and meniscal lesions, and osteophytes) assessed with the MRI OA Knee Score. Logistic regression analyses evaluated the odds of early KOA features with an accelerated return to sport (<10 months post-ACLR versus ≥10 months or no return to sport) in the total cohort and stratified by type of ACL injury and lower limb function.

Results

Forty-six (41%) participants returned to competitive sport <10 months post-ACLR. An early return to sport was associated with significantly increased odds of bone marrow lesions (odds ratio [OR] 2.7, 95% confidence interval [CI] 1.3-6.0) but not cartilage (OR 1.2, 95% CI 0.5-2.6) or meniscal lesions (OR 0.8, 95% CI 0.4-1.8) or osteophytes (OR 0.6, 95% CI 0.3-1.4). In those with poor lower limb function, early return to sport exacerbated the odds of bone marrow lesions (OR 4.6, 95% CI 1.6-13.5), whereas stratified analyses for type of ACL injury did not reach statistical significance.

Conclusion

An accelerated return to sport, particularly in the presence of poor lower limb function, may be implicated in posttraumatic KOA development.

Background

Malignant brain tumors cause significant impairments in function because of the nature of the disease. Nevertheless, patients with malignant brain tumors can make functional gains equivalent to those with stroke and traumatic brain injury in the inpatient rehabilitation setting. However, the efficacy of outpatient rehabilitation in this population has received little study.

Objective

To determine if an interdisciplinary outpatient rehabilitation program will improve functional outcomes in patients with malignant brain tumors.

Design

Nonrandomized prospective longitudinal study.

Setting

Six affiliated outpatient sites of one institution.

Patients

Forty-nine adults with malignant brain tumors were enrolled.

Methods

Patients received interdisciplinary therapy services, with duration determined by the therapist evaluations. The therapists scored the Day Rehabilitation Outcome Scale (DayROS) and Disability Rating Scale (DRS) on admission and discharge. The caregivers filled out the DRS at discharge, 1 month, and 3 months after discharge.

Main Outcome Measurements

The primary study outcome measure was the DayROS, which is a functional measure similar to the Functional Independence Measure. DRS was another functional outcome measure assessing basic self-care, dependence on others, and psychosocial adaptability.

Results

Forty-six of 49 enrolled patients (94%) completed the day rehabilitation program. The average length of stay was 76.9 days. There was a significant improvement in total DayROS (P < .001), mobility (P < .001), Activities of Daily Living ( P < .001), and communication (P < .001) DayROS subscores from admission to discharge. There were no significant changes over time in the DRS scores. Women had higher DayROS gains (P = .003) and better therapist DRS scores from admission to discharge than men (P = .010).

Conclusions

Patients with malignant brain tumors can make functional gains in an interdisciplinary outpatient rehabilitation program. This level of care should be considered in this patient population.

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.

Objectives

To evaluate (1) the trajectory of resilience during the first year after a moderate-severe traumatic brain injury (TBI); (2) factors associated with resilience at 3, 6, and 12 months postinjury; and (3) changing relationships over time between resilience and other factors.

Design

Longitudinal analysis of an observational cohort.

Setting

Five inpatient rehabilitation centers.

Participants

Patients with TBI (N=195) enrolled in the resilience module of the TBI Model Systems study with data collected at 3-, 6-, and 12-month follow-up.

Interventions

Not applicable.

Main Outcome Measure

Connor-Davidson Resilience Scale.

Results

Initially, resilience levels appeared to be stable during the first year postinjury. Individual growth curve models were used to examine resilience over time in relation to demographic, psychosocial, and injury characteristics. After adjusting for these characteristics, resilience actually declined over time. Higher levels of resilience were related to nonminority status, absence of preinjury substance abuse, lower anxiety and disability level, and greater life satisfaction.

Conclusions

Resilience is a construct that is relevant to understanding brain injury outcomes and has potential value in planning clinical interventions.  相似文献

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.
