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.Level of Evidence

Background
The intervertebral disk is the largest avascular structure in the body. It relies on passive diffusion from arteries at the periphery of the disk for nutrition. Previous studies have suggested a correlation between vascular disease and lumbar degenerative disk disease (DDD), but the association with facet arthritis and stenosis has not been evaluated.Objective
To evaluate the degree of lumbar artery stenosis, aortic atherosclerosis on computed tomography angiography, and its relationship to lumbar DDD, facet arthritis, and spinal canal stenosis.Design
Retrospective case review.Setting
Academic tertiary care hospital.Participants
Not applicable.Methods
A total of 300 lumbar arteries (150 lumbar artery pairs of the first to fifth lumbar arteries) were evaluated on consecutive computed tomography angiography scans. Severity of vascular disease of lumbar arteries was documented as normal, mild, moderate, severe, or occluded. Aortic vascular disease was documented along the posterior wall where the lumbar arteries originate.Main Outcome Measurements
The relationship between vascular disease with DDD, facet arthritis, and spinal canal stenosis was examined and further evaluated controlling for age.Results
Lumbar artery and aortic atherosclerosis had a positive relationship with DDD, facet arthritis, and spinal stenosis that was statistically significant (P < .05) even after controlling for age. The correlation coefficient was greatest in the younger age group when looking at lumbar artery vascular disease with DDD (0.73, confidence interval 0.50-0.96, P < .0001) and aortic vascular disease with DDD (0.72, confidence interval 0.49-0.94, P < .0001). The correlation of vascular disease with facet arthritis and stenosis was not strong in the older age group.Conclusion
Atherosclerotic disease of the lumbar arteries and aorta correlated with lumbar DDD, facet arthritis, and spinal canal stenosis after we adjusted for age, although the correlation with facet arthritis and spinal canal stenosis was not as strong in the older age group.Level of Evidence

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.Level of Evidence

Background
Low back pain (LBP) is commonly associated with paraspinal muscle dysfunctions. A method to study deep lumbar paraspinal (ie, multifidus) muscle function and neuromuscular activation pattern is intramuscular electromyography (EMG). Previous studies have shown that the procedure does not significantly impact muscle function during activities involving low-level muscle contractions. However, it is currently unknown how muscular function and activation are affected during high-exertion contractions.Objective
To examine the effects of insertion and presence of fine-wire EMG electrodes in the lumbar multifidus on muscle strength, endurance, and activation profiles during high-exertion spinal extension muscle contractions.Design
Single-blinded, repeated measures intervention trial.Setting
University clinical research laboratoryParticipants
Twenty individuals between the ages of 18-40 free of recent and current back pain.Methods
Muscle performance was assessed during 3 conditions (with [WI] and without [WO] presence of intramuscular electrodes, and insertion followed by removal [IO]). Isometric spinal extension strength was assessed with a motorized dynamometer. Muscle endurance was assessed using the Sorensen test with neuromuscular activation profiles analyzed during the endurance test.Main Outcome Measurements
Spinal extensor muscle strength, endurance, and activation.Results
Our data showed no significant difference in isometric strength (P = .20) between the 3 conditions. A significant difference in muscle endurance was found (P = .03). Post hoc analysis showed that the muscle endurance in the IO condition was significantly higher than the WO condition (161.3 ± 58.3 versus 142.1 ± 48.2 seconds, P = .04), likely due to a learning effect. All 3 conditions elicited minimal pain (range 0-4/10) and comparable muscle activation profiles.Conclusion
Our findings suggested the sonographically guided insertion and presence of fine-wire intramuscular EMG electrodes in the lumbar multifidus muscles had no significant impact on spinal extension muscle function. This study provides evidence that implementing intramuscular EMG does not affect muscle performance during high-exertion contractions in individuals with no current back pain.Level of Evidence

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.Level of Evidence

Background
Lumbar stabilization exercise programs (LSEP) produce positive effects on clinical outcomes, but the underlying mechanisms remain relatively unexplored. Psychological and neuromuscular mechanisms can be involved, such as a better activation of the lumbar multifidus, which represents one possibility.Objectives
To determine the following: (1) the effect of an LSEP on lumbar multifidus muscle thickness and activation, as measured with rehabilitative ultrasound imaging (RUSI), in patients with low back pain (LBP); (2) the correlation between RUSI measures and any change in clinical outcomes following the LSEP; and (3) the reliability of RUSI measures in control subjects over 8 weeks.Design
One-arm clinical trial with healthy subjects as a control group; reliability study.Setting
LSEP delivered in a clinical setting; outcomes measured in a laboratory setting.Participants
A total of 34 patients with nonacute LBP and 28 healthy control subjects.Methods
Outcomes were measured before and after an 8-week LSEP in patients with LBP, and at the same time interval (without treatment, to assess reliability) in control subjects.Main Outcome Measurements
Pain numeric rating scale, Oswestry Disability Index (function), as well as RUSI measures for the lumbar multifidus (LM) muscles at 3 vertebral levels (L5-S1, L4-5, and L3-4) during rest (static) and dynamic contractions (percent thickness change).Results
Patients did not show systematic changes in RUSI measures relative to controls, even though RUSI impairments were observed at baseline (dynamic measure at L5-S1) and even though patients had significant improvements in pain and disability. Correlational analyses with these clinical outcomes suggested that patients had reduced muscle thickness at baseline that was associated with a greater reduction in disability following LSEP; however, LM activation measured at baseline showed the opposite. Static RUSI measures showed excellent reliability at the L4-5 and L3-4 levels, whereas dynamic measures were not reliable.Conclusions
Patients showed less muscle activation than controls at baseline (L5-S1 level), but the LSEP did not normalize this impairment. The links between RUSI measures and the change in clinical outcomes during LSEP should be further explored.This clinical trial has been recorded in the International Standard Registered Clinical/soCial sTudy Number (ISRCTN) registry (ID: ISRCTN94152969).Level of Evidence

Background
Cerebral palsy (CP) is one of the most disabling syndromes in children. To our knowledge, there has not yet been any reported evaluation by ultrasonography of the effect of CP on distal femoral cartilage. The value of understanding this effect on cartilage is that sonographic evaluation of cartilage thickness may help physicians to predict the joint health of these children.Objective
To determine whether femoral cartilage thickness in patients with CP is different from that in healthy control subjects.Design
Cross-sectional study.Setting
National tertiary rehabilitation center.Patients
The study included 40 patients with diplegic CP (23 male and 17 female) and 51 healthy control subjects (29 male and 22 female).Methods
Demographic and clinical characteristics were recorded. Cartilage thicknesses were measured.Main Outcome Measure
Cartilage thickness measurements were taken from the medial and lateral condyles, and intercondylar areas of both knees.Results
Both groups were similar in terms of age, gender, and weight (P > .05). The mean cartilage thickness measurements of the medial condyle and intercondylar area of knees in the CP group were significantly less than those in the healthy control group (all P < .05). There was moderate negative correlation between age and all femoral cartilage thickness measurements in the CP group. There was no correlation between age and femoral cartilage thickness measurements in the healthy group. There was a negative correlation between Gross Motor Functional Classification System levels and cartilage thickness in the CP group. The highest cartilage thickness measurements were detected in level 1 patients, and the lowest measurements were detected in level 5 patients.Conclusion
This study showed that patients with CP have a thinner femoral cartilage than healthy control subjects. Management of patients with CP should include close surveillance.Level of Evidence

Background
Relationships between low back pain (LBP) and the hip in patient cohorts have been described primarily in patients with moderate to severe hip osteoarthritis (OA). Less is known about the links of LBP with hip radiographic findings of hip deformity and minimal OA.Objective
To describe the incidence of radiographic hip deformity or hip OA; to describe and compare spine- and hip-related pain and function in the subset of patients who were found to have radiographic hip deformity or hip OA; and to compare patients with evidence of radiographic hip deformity or hip OA to patients without hip radiographic findings.Design
Prospective cohort study with cross-sectional design.Setting
Tertiary university.Patients
A total of 63 patients (40 women, 23 men) with a mean age of 48.5 ± 14 years with LBP and a minimum of one positive provocative hip test.Methods
Hip radiographs were assessed by an independent examiner for hip OA and deformity.Main Outcome Measurements
Comparisons of hip and lumbar spine pain and function were completed for patients with radiographic findings of hip OA or deformity.Results
Moderate to severe hip OA was found in 12 of 60 patients (20.0%). At least one measurement of femoroacetabular impingement (FAI) was found in 14 of 60 patients (23.3%) to 33 of 45 patients (73.3%). At least one measurement of developmental hip dysplasia (DDH) was found in 7 of 60 patients (11.6%) to 11 of 63 patients (17.4%). Greater pain and reduced hip and lumbar spine function were found in the patients with moderate to severe hip OA. Patients with LBP and FAI were found to have significantly greater extremes of pain and reduced lumbar spine function.Conclusion
Links between the hip and the spine affecting pain and function may be found in patients with LBP and hip deformity and before the onset of radiographic hip OA, and may be associated with hip deformity. Further investigation is needed to better understand these links and their potential impact on prognosis and treatment of LBP.Level of Evidence

Background
No study has investigated the relationship between the findings of contrast-enhanced magnetic resonance imaging (CE-MRI) and the joint volume of the shoulder, which has been considered the standard reference for diagnosis of adhesive capsulitis (AC).Objective
To investigate the relationships among the capsulo-synovial thickness measured by CE-MRI, joint volume, and passive range of motion (ROM) in patients with AC.Design
This was a retrospective study.Setting
The study took place at an institutional practice.Patients
Medical record of 103 patients (46 male and 57 female), who were treated with sonographically guided intra-articular injection with diagnosis of AC and underwent CE-MRI to rule out other concomitant shoulder disease, were retrospectively reviewed.Methods
Passive ROM and glenohumeral joint (GHJ) volume were measured before and during sonographically guided injection. The thickness of the enhancing portion of the capsulo-synovium was measured at the axillary recess and rotator interval on CE-MRI.Main Outcome Measurements
The relationship among the thickness of the enhancing portion on CE-MRI, GHJ volume, and passive ROM was analyzed using the Pearson correlation coefficient.Results
Capsulo-synovial thickness measured by CE-MRI at the enhancing portion of the axillary recess inversely correlated with GHJ volume (ρ = ?0.444, P < .001), whereas at the rotator interval, this finding was not observed. At the axillary recess, the capsulo-synovial thickness inversely correlated with abduction (ρ = ?0.400, P < .001), forward elevation (ρ = ?0.378, P < .001), and external rotation (ρ = ?0.297, P < .01), but at the rotator interval, such statistically significant correlations were not shown.Conclusion
The capsulo-synovial thickness measured by CE-MRI at the enhancing portion of the axillary recess could represent obliterated joint capacity and clinical impairment (restricted passive ROM), which could help in diagnosing AC and in differentiating other shoulder diseases that may mimic this condition.Level of Evidence

Background
Spondylolysis with and without anterolisthesis is the most common cause of structural back pain in children and adolescents, but few predictive factors have been confirmed. An association between abnormal sacropelvic orientation and both spondylolysis and spondylolisthesis has been supported in the literature. Sacral slope and other sacropelvic measurements are easily accessible variables that could aid clinicians in assessing active adolescents with low back pain, particularly when the diagnosis of spondylolysis is suspected.Objective
To examine the relationship between sacral slope and symptomatic spondylolysis in a cohort of active adolescents.Design
Case-control retrospective study.Setting
Academic outpatient physiatry practice.Patients
Seventy-four patients of primarily adolescent age (between 12 and 22 years old) with a chief complaint of low back pain and presence of lateral radiographs of the lumbar spine were enrolled. Cases (n = 37) were defined as subjects with evidence of spondylolysis on both radiograph and magnetic resonance imaging of the lumbar spine. Controls (n = 37) were defined as subjects without spondylolysis.Methods
Using a single sagittal radiograph, taken with the patient standing, a fellowship-trained interventional spine physiatrist measured the sacral slope of each subject (angle between the superior plate of S1 and a horizontal reference on sagittal imaging of the lumbosacral spine). Ages and genders were collected from medical records.Main Outcome Measurements
The primary outcome was mean sacral slope. Mean sacral slope of cases was compared with mean sacral slope of controls with the Student t-test.Results
Ages ranged from 12 to 22 for both groups, with no significant differences in age between the groups (cases: 16.8 ± 2.3 years; controls: 17.7 ± 2.7 years). The patients with spondylolysis (cases) consisted of 29 male and 8 female patients, whereas those without spondylolysis (controls) consisted of 15 male and 21 female patients (gender details for 1 patient were not available). The mean sacral slope among cases was 42.4°, whereas the mean sacral slope among controls was 37.4°. The difference achieved significance (P = .014).Conclusions
The interdependence of positional parameters, such as sacral slope, with anatomic parameters, such as pelvic incidence, can affect lumbar lordosis and therefore upright positioning and loading of the spine. Sacral slope may be an important variable for clinicians to consider when caring for young athletes with low back pain, particularly when the index of suspicion for spondylolysis is high.Level of Evidence

Background
Adipose tissue produces leptin, which is pro-inflammatory, and adiponectin, which has anti-inflammatory properties. Participants with chronic spinal cord injury (SCI) have increased body fat and are at increased risk for respiratory illness.Objective
To assess the associations between leptin and adiponectin with pulmonary function in a chronic SCI cohort.Design
Cross-sectional study.Setting
Veterans Affairs Medical Center.Participants
A total of 285 participants (237 men and 48 women) with chronic SCI with mean (standard deviation) injury duration 17.8 (13.2) years from the VA Boston and the community participating in an epidemiologic study assessing factors associated with respiratory health.Methods
Participants (24.6% cervical American Spinal Injury Association Impairment Scale (AIS) level A, B, and C; 33.6% other AIS A, B, and C; 41.8% AIS D) provided a blood sample, completed a respiratory health questionnaire, and underwent spirometry. Linear regression methods were used to assess cross-sectional associations between plasma leptin and adiponectin with spirometric measures of pulmonary function adjusted for age, race, gender, and height. Level and severity of SCI, mobility mode, body mass index, smoking, chronic obstructive pulmonary disease, asthma, chest injury history, laboratory batch, and other potential confounders were also considered.Main Outcome Measurements
forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and FEV1/FVC.Results
There was a statistically significant inverse relationship between plasma leptin assessed in quartiles or as a continuous covariate with FEV1 and FVC. In fully adjusted models, each interquartile range (16,214 pg/mL) increase in leptin was associated with a significant decrease in FEV1 (?93.1 mL; 95% confidence interval = ?166.2, ?20.0) and decrease in FVC (?130.7 mL; 95% confidence interval = ?219.4, ?42.0). There were no significant associations between leptin and FEV1/FVC or between plasma adiponectin with FEV1, FVC, or FEV1/FVC.Conclusion
Plasma leptin in individuals with chronic SCI is inversely associated with FEV1 and FVC, independently of SCI level and severity and other covariates. This finding suggests that plasma leptin may contribute to reduced pulmonary function in chronic SCI.Level of Evidence

Background
Women are at greater risk for knee osteoarthritis and numerous other lower limb musculoskeletal disorders. Arch drop during pregnancy and the resultant excessive pronation of the feet may alter loading patterns and contribute to the greater prevalence of knee osteoarthritis in women.Objective
To determine the effect of arch drop on tibial rotation and tibiofemoral contact stress.Design
Interventional study with internal control.Setting
Biomechanics laboratory.Participants
Eleven postpartum women (age 33.4 ± 5.3 years, body mass 76.1 ± 13.5 kg) who had lost arch height with pregnancy in a previous study.Methods
Subjects underwent standing computed tomography (SCT) with their knees in a 20° fixed-flexed position with and without semirigid arch supports to reconstitute prepregnancy arch height. Magnetic resonance imaging of the knee was acquired at a flexion angle equivalent to that of SCT. Bone and cartilage were manually segmented on the magnetic resonance images and segmented surfaces were registered to the 3-dimensional SCT image sets for the arch-supported and -unsupported conditions. These models were used to measure changes in tibial rotation, as well as to estimate contact stress in the medial and lateral tibiofemoral compartments, using computational methods.Main Outcome Measures
Change in tibial rotation and tibiofemoral contact stress with arch drop.Results
Arch drop resulted in a mean tibial internal rotation of 0.75 ± 1.33° (P = .02). Changes in mean or peak contact stress were not detected.Conclusions
Arch drop causes internal tibial rotation, resulting in a shift in the tibiofemoral articulation. An associated increase in contact stress was not detected. Internal rotation of the tibia increases stress on the anterior cruciate ligament and menisci, potentially explaining the greater prevalence of knee disorders in postpartum women.Level of Evidence

Background
There is controversy regarding the best technique for applying Kinesio Taping (KT), and the theory supporting that skin convolutions may explain its efficacy has recently been challenged.Objective
To compare the immediate and short-term effectiveness of KT tightness on mechanosensitivity and spinal mobility in nonspecific low back pain (LBP), and to observe the influence of gender in the outcome measures.Design
Double-blind, randomized, controlled trial.Setting
University-based clinical research center.Participants
A total of 75 individuals with a mean age of 33 years (±7.4 years), 60% female and 40% male, with nonspecific LBP were recruited and randomly assigned to 1 of the following study groups: standard KT tension (n = 26), increased KT tension (n = 25), and no KT tension (n = 24).Interventions
All participants received a two I-strip taping over the paravertebral muscles for 24 hours. Paper-off tension (15%-25% of the available stretch) was used in the standard KT group, which was increased to 40% in the increased KT tension group. The rest of participants received a taping procedure with no KT tension. Measurements were taken at baseline, immediately after the taping, 24 hours after the taping, and after KT removal.Main Outcome Measures
The primary outcome included pressure pain thresholds over the erector spinae and gluteus medius muscles. The secondary outcome was lumbar mobility (assessed with a digital inclinometer, and back-saver sit-and-reach, finger-to-floor, and sit-and-reach tests).Results
In the between-groups analysis of the mean score changes after baseline assessment, no significant differences were found for any of the outcome measures (P > .05) except the left back-saver sit-and-reach test (P = .03). A statistically significant interaction group × gender × time was observed only for mechanosensitivity values (P = .02 for the gluteus and P = .01 for the erector spinae).Conclusion
KT tightness does not seem to influence pain sensitivity and lumbar mobility in chronic LBP in either the immediate or short term.Level of Evidence

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.Level of Evidence

Background
Ideally, high-stakes examinations assess 1 dimension of medical knowledge to produce precise estimates of a candidate’s performance.

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.Level of Evidence

Background
As our population ages, neurogenic claudication (NC) from central canal stenosis of the lumbar spine is becoming an increasingly common condition. Studies have been undertaken to assess the efficacy of caudal, interlaminar, or unilateral transforaminal epidural injections, but bilateral transforaminal epidural injections (BTESIs) have not been evaluated to date.Objective
To assess the therapeutic value and long-term effects of fluoroscope-guided BTESIs in patients with NC from degenerative lumbar spinal stenosis (DLSS) of the central spinal canal.Design
Case series.Setting
Single institution spine clinic.Patients
Twenty-six adults between the ages of 40 and 90 years with a diagnosis of DLSS and a history of subacute or chronic NC.Methods/Interventions
Patients meeting inclusion criteria received fluoroscope-guided BTESI of local anesthetic and steroid at the level immediately below the most stenotic level. Patient self-reported pain level, activity level, and overall satisfaction were recorded by telephone interview at 1, 3, and 6 months after injection by an independent observer.Main Outcome Measures
Pain score and Swiss Spinal Stenosis score at baseline, 1, 3, and 6 months.Results
Of the 22 participants eligible for analysis, 20, 19, and 18 had follow-up data available at 1, 3, and 6 months, respectively. Reduction in numeric pain scale score of at least 50% was noted in 30% of participants at 1 month, 53% at 3 months, and 44% at 6 months. Swiss Spinal Stenosis subscale scores indicated a significant reduction in the proportion of participants reporting the presence of severe pain in the back, buttocks, and legs (particularly the back or buttocks) at 1, 3, and 6 months of follow-up compared with baseline (P < .05). The proportion of participants reporting severe weakness in the legs or feet also decreased after injection and was statistically significant at 3 months of follow-up (P = .04).Conclusions
Fluoroscope-guided BTESI was moderately effective in reducing pain, improving function, and achieving patient satisfaction in patients with NC from DLSS at the central spinal canal in this clinical case series.Level of Evidence
