Evaluation of Longitudinal Assessment for use in Maintenance of Certification Objective To evaluate a longitudinal assessment process (LA-PM&R) as a replacement for the American Board of Physical Medicine and Rehabilitation (ABPMR) Maintenance of Certification (MOC) Examination. Design In this quality improvement study, randomly selected ABPM&R diplomates were invited to participate in LA-PM&R. Participants’ MOC scaled scores were compared to LA-PM&R non-participants. We examined the association between LA-PM&R scores and MOC Scaled scores and performance on clone items placed on both examinations. Results There were 2,222 ABPM&R diplomates eligible to take the MOC Examination February 2018 through February 2019. Invitations were sent to 1,050 randomly selected diplomates, of whom 448 initially agreed. 318 individuals completed > 2 quarters of LA-PM&R participation and took the MOC Examination. 266 diplomates took the MOC Examination in the same time period who did not participate in LA-PM&R. The LA-PM&R group scored higher on the MOC Examination than the control group (P < .05). Performance on the 2 examinations were highly correlated, r = .50, P < .0001. On clone items, LA-PM&R participants had 74% correct on LA-PM&R but 86% correct on the MOC Examination (P < .01). Conclusions The LA-PM&R program leads to better learning and retention of information than the 10-year MOC Examination. Corresponding Author: Lawrence R.

Effectiveness of hydrotherapy on balance and paretic knee strength in patients with stroke: A systematic review and meta-analysis of randomized controlled trials Objective To compare the effects of hydrotherapy and land-based conventional therapy (CT) on postural balance and knee strength in stroke patients. Designs A comprehensive search was done via databases (PubMed, EMBASE, and Web of Science) until April, 12th, 2019 to select randomized controlled trials. The methodological quality was assessed by the PEDro scale. Berg Balance Scale (BBS) was pooled as the primary outcome, and Forward Reach Test (FRT), Timed Up and Go test (TUG), and paretic knee flexor (KF), knee extensor (KE) torque as secondary outcomes. Results Eleven articles were included. Pooled results showed that hydrotherapy was more beneficial in stroke patients on BBS (mean difference (MD)=1.60, 95% confidence interval (CI): 1.00-2.19), FRT (MD=1.78, 95% CI: 0.73-2.83), TUG (MD=-1.41, 95% CI: -2.44--0.42), and KE torque (MD=6.14, 95% CI: 0.59-11.70) than CT. In subgroup analysis according to stroke-onset duration, hydrotherapy for chronic stroke patients exhibited significant effectiveness on BBS (MD=1.61, 95% CI: 1.00-.21); no significant effect was observed in subacute stroke patients (MD=1.04, 95% CI: -2.62-4.70). Conclusion Stroke patients showed improvement in postural balance and paretic knee extensor strength with hydrotherapy. Hydrotherapy exhibited significant effects on improving postural balance in chronic patients than in subacute patients. Corresponding author: Professor.

The Relationship between MS Symptom Severity Measures and Performance on Driving Variability Metrics in a Virtual Reality Simulator Objective Driving ability can be compromised in individuals with multiple sclerosis (MS); however, the progressive nature of MS makes it difficult for clinicians to assess when performance on functional tasks, such as driving, has started to decline. The objective of this study was to evaluate the relationship between two measures of MS severity, the Expanded Disability Status Scale (EDSS) and the Multiple Sclerosis Functional Composite (MSFC), and minor driving errors in a virtual reality driving simulator (VRDS). Design Symptom severity was measured in thirty-one active drivers with MS using the EDSS and MSFC. Driving performance was measured using a standardized VRDS route. Executive functioning, a cognitive function commonly related to driving, was evaluated using the Trail Making Test-B. Results Greater impairment on the MSFC was related to increased difficulty maintaining lane positioning (r=-.49, p=.01) and poorer executive functioning (r=-.52, p<.01). In contrast, the EDSS was not related to either measure. Conclusion These findings suggest that poorer performance on the MSFC, and not the EDSS, may indicate vulnerability to minor driving errors as an early sign of driving compromise. The use of screening tools like the MSFC could help clinicians identify increased driving risk and consider comprehensive driving evaluations earlier, before a major driving violation or accident occurs.

Ultrasound Imaging and Rehabilitation of Muscle Disorders Part 2. Non-Traumatic Conditions Owing to its several advantages, ultrasound (US) imaging has started to take place in the diagnostic and therapeutic algorithms of a wide range of musculoskeletal disorders. After the 1st part on traumatic conditions; in this review, the authors aim to discuss the applicability of US imaging for non-traumatic muscle disorders in the daily clinical/academic practice. While trying to summarize the whole spectrum (e.g. myofascial pain syndrome, inflammatory diseases, neuromuscular disorders), special emphasis will be given to sarcopenia which is, by far, the most challenging clinical condition in the era of ‘aging world’. Of note, rehabilitation as regards the exemplified problems will also be briefed throughout.

Swallowing outcomes and discharge destinations in acute-stroke tube-feeding-dependent dysphagia patients treated with neuromuscular-electrical-stimulation during inpatient rehabilitation Objective Inpatient-rehabilitation (IR) study comparing swallowing outcomes and discharge destinations in acute-stroke tube-feeding-dependent dysphagia patients treated with neuromuscular-electrical-stimulation (NMES) and traditional-dysphagia-therapy (TDT) versus those treated with only TDT. Design Retrospective case-control study including 359 patients with acute-stroke having initial Functional-Oral-Intake-Scale (FOIS) scores of 3 or lower (profound to severe tube-feeding-dependent dysphagia). One-hundred-ninety participants received NMES with TDT, and 169 controls received only TDT. Treatment occurred in hourly sessions 5-days/week. Main outcome measures were comparison of FOIS scores after treatment (N=359) and comparison of discharge destinations (N=267). Results NMES post-treatment mean FOIS score was 4.21+/-2.1 versus 2.94+/-1.96 for controls (t=5.85;p<.001). NMES group post-treatment mean FOIS gain was 3.24+/-2.26 points versus 1.87+/-2.01 for controls (t=6.05;p<.001). Post-treatment, 51.6% (98/190) NMES patients had minimal or no swallowing restrictions (FOIS scores 5-7), whereas only 26.6% (45/169) controls improved to FOIS scores of 5-7, (χ2 =23.3;p<.0001). Groups differed by discharge destinations: NMES having more discharges to community than controls, 60% versus 44% (χ2=9.16;p=.003), and NMES having fewer acute-care transfers compared to controls, 8% versus 25%, (χ2=32.7;p<.0001). Conclusions NMES with TDT was associated with better discharge swallowing outcomes and FOIS scores than TDT alone during IR in treating acute-stroke feeding-tube-dependent dysphagia; and was associated with more discharges to community and less transfers back to acute-care.

“Dysphagia in myositis: A study of the structural and physiologic changes resulting in disordered swallowing.” Objectives Dysphagia in patients with myositis is associated with an increased risk of aspiration pneumonia. However, the pathophysiology of dysphagia is poorly understood. The goal of this study was to understand how myositis affects swallowing physiology on videofluoroscopic swallow study (VFSS). Design Retrospective review of video fluoroscopic swallowing studies on 23 myositis patients with dysphagia from 2011 to 2016. Swallow studies were analyzed by timing of swallowing events and duration of swallowing events, diameter of upper esophageal sphincter opening (UESO), Modified Barium Swallow Impairment Profile, and Penetration-Aspiration Scale. The outcome measures for patients were compared to archived VFSS from healthy, age-matched participants by Wilcoxon rank-sum tests. Results Patients with myositis had a shorter duration of UESO (p<0.0001) and laryngeal vestibule closure (p<0.0001) than healthy subjects. The diameter of upper esophageal sphincter opening did not differ between groups. Patients with myositis presented with higher scores on the MBSIMP than healthy subjects, indicating great impairment particularly during the pharyngeal phase of swallowing, and a higher frequency of penetration and aspiration. Conclusion Dysphagia in patients with myositis may be attributed to reduced endurance of swallowing musculature rather than mechanical obstruction of the retropharyngeal space.
