Objective: Blood flow restriction (BFR) training, in which an inflatable cuff partially occludes blood flow around the proximal portion of a limb, coupled with low-intensity resistance training (LIRT) has resulted in gains comparable with traditional progressive resistive exercise in healthy populations. The use of BFR with LIRT may enable people with multiple sclerosis (MS) to improve strength without an increase in fatigue. The purpose of this case report is to describe the use of a BFR/LIRT program for a person with MS. Methods: The patient was a 54-year-old woman with a 13-year history of primary progressive MS with an Extended Disability Severity Score of 3.0 out of 10. She received a BFR/LIRT program for both lower extremities biweekly for 12 weeks. Outcomes measured at baseline and at 6 and 12 weeks included the 12-item Multiple Sclerosis Walking Scale (MSWS-12), Fatigue Severity Scale, Patient-Specific Functional Scale (PSFS) (goals: running for exercise and pleasure for 45 minutes, 100% confidence in negotiating a flight of stairs, confidently and safely drive without restriction), and 14 lower extremity strength tests. Results: The intervention was well tolerated without adverse events. After 6 weeks, the MSWS-12 score improved; however, it did not exceed minimum detectable change (MDC). Fatigue Severity Scale was unchanged. All PSFS goals improved beyond MDC, and improvements in strength exceeded MDC in 2 out of 14 tests. After 12 weeks, MSWS-12 improvements persisted and the Fatigue Severity Scale score improved, but neither exceeded MDC. The PSFS improvements persisted. There were improvements exceeding MDC for 8 out of 14 strength tests. The remaining 6 strength tests improved but did not exceed MDC. Conclusion: The patient had measurable improvements following the use of a BFR/LIRT program. BFR/LIRT may be an option for strength training in people with MS; however, research is needed to determine its safety and effectiveness across the population of people with MS. Impact: Traditional physical therapist interventions for people with MS have been shown to be beneficial; however, their usefulness has been limited by fatigue. A growing body of literature has demonstrated the effects of a BFR/LIRT program on strength and other measures of physical function in healthy populations and those with chronic disease. This case report adds missing information to the existing literature and suggests directions for research on the effectiveness of BFR/LIRT in people with primary progressive MS. Lay Summary: Blood flow restriction, which has been used to help improve strength in healthy adults and in some people with chronic disease, applies pressure around the arm or leg to limit the flow of blood to that body part during exercise, helping to reduce fatigue. Blood flow restriction coupled with low-intensity strengthening exercises can be used for a person with MS.

Fatigue is a common, disabling symptom experienced by persons with multiple sclerosis (MS). Evidence shows that intermittent exercise is associated in improved performance and negligible fatigue. The purpose of this study was to examine whether subjects with MS walk greater distances with less fatigue under intermittent (INT) or continuous (CONT) walking condition. Twenty-seven subjects with MS (median Extended Disability Severity Scale 3.5, interquartile range 1.6) walked in the CONT (ie, 6 uninterrupted minutes) and INT (ie, three 2-minute walking bouts) conditions in a randomized crossover. Distance was measured for the entire 6-minute walking period and each 2-minute increment. Fatigue was measured as the difference in a visual analog scale of fatigue (ΔVAS-F) immediately preceding and following each trial. Participants walked greater distances in the INT condition compared to the CONT condition (P = 0.005). There was a significant interaction of walking condition and time (P < 0.001), indicating that the distances walked in the INT condition changed across time. ΔVAS-F was significantly lower in the INT condition than in the CONT condition (P = 0.036). Subjects with MS walked farther, and with less fatigue, when walking intermittently rather than continuously. Persons with MS may be able to tolerate a greater dose of walking training if the walking bouts are intermittent. Further study to determine the benefits of a walking exercise program using intermittent walking is recommended.Video Abstract available for additional insights from the authors (Supplemental Digital Content 1, http://links.lww.com/JNPT/A103).

Despite the well-known benefits of using standardized outcome measures (OMs) in clinical practice, a variety of barriers interfere with their use. In particular, rehabilitation therapists lack sufficient knowledge in selecting appropriate OMs. The challenge is compounded when working with people with multiple sclerosis (MS) owing to heterogeneity of the patient population and symptom variability in individual patients. To help overcome these barriers, the American Physical Therapy Association appointed the Multiple Sclerosis Outcome Measures Task Force to review and make evidence-based recommendations for OM use in clinical practice, education, and research specific to people with MS. Sixty-three OMs were reviewed based on their clinical utility, psychometric properties, and a consensus evaluation of the appropriateness of use for people with MS. We sought to illustrate use of the recommendations for two cases. The first case involves a 43-year-old man with new-onset problems after an exacerbation. The second case pertains to an outpatient clinic interested in assessing the effectiveness of their MS rehabilitation program. For each case, clinicians identified areas that were important to assess and various factors deemed important for OM selection. Criteria were established and used to assist in OM selection. In both cases, the described processes narrowed the selection of OMs and assisted with choosing the most appropriate ones. The recommendations, in addition to the processes described in these two cases, can be used by clinicians in any setting working with patients with MS across the disability spectrum.

Background and Purpose: The symptom of fatigue impairs function in people with multiple sclerosis (MS). Choosing appropriate measures to assess fatigue is challenging. The purpose of this article is to report the findings of a systematic review of patient-reported fatigue measures for people with MS. Methods: PubMed, CINAHL, and Embase databases were searched through January 2020 using terms related to fatigue and MS. Studies were included if the sample size was 30 or more or smaller samples if adequately powered, and if information about measurement characteristics (ie, test-retest reliability, content validity, responsiveness, interpretability, or generalizability) of the measure(s) could be extracted. Study quality was appraised with the 2-point COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. Data about measurement characteristics, psychometrics, and clinical utility were extracted and results were synthesized. Results: Twenty-four articles met inclusion criteria with information about 17 patient-reported fatigue measures. No studies had critical methodologic flaws. Measurement characteristic data were not available for all measures. Clinical utility varied in time to complete and fatigue domains assessed. Discussion and Conclusions: Five measures had data pertaining to all properties of interest. Of these, only the Modified Fatigue Impact Scale (MFIS) and Fatigue Severity Scale (FSS) had excellent reliability, responsiveness data, no notable ceiling/floor effects, and high clinical utility. We recommend the MFIS for comprehensive measurement and the FSS for screening of subjective fatigue in people with MS.

Background: This pilot study determined the feasibility of a specifically designed 8-week yoga program for people with moderate multiple sclerosis (MS)–related disability. We explored the program's effect on quality of life (QOL) and physical and mental performance. Methods: We used a single-group design with repeated measurements at baseline, postintervention, and 8-week follow-up. Feasibility was examined through cost, recruitment, retention, attendance, and safety. Outcomes included the Multiple Sclerosis Quality of Life Inventory (MSQLI), 12-item Multiple Sclerosis Walking Scale (MSWS-12), Timed 25-Foot Walk test (T25FW), 6-Minute Walk Test (6MWT), Nine-Hole Peg Test (NHPT), Five-Times Sit-to-Stand Test (FTSTS), Multidirectional Reach Test (MDRT), maximum expiratory pressure, and Paced Auditory Serial Addition Test-3″ (PASAT-3″). Results: Fourteen participants completed the study. The program was feasible. There were significant main effects on the 36-item Short Form Health Status Survey Mental Component Summary (SF-36 MCS), Modified Fatigue Impact Scale (MFIS), Bladder Control Scale (BLCS), Perceived Deficits Questionnaire (PDQ), Mental Health Inventory (MHI), MSWS-12, T25FW, NHPT, PASAT-3″, 6MWT, FTSTS, and MDRT-Back. Improvements were found on the SF-36 MCS, MFIS, BLCS, PDQ, MHI, and MSWS-12 between baseline and postintervention. The effect on PDQ persisted at follow-up. Improvements were found on the T25FW, NHPT, 6MWT, FTSTS, and MDRT-Back between baseline and postintervention that persisted at follow-up. The PASAT-3″ did not change between baseline and postintervention but did between postintervention and follow-up. Conclusions: The yoga program was safe and feasible. Improvements in certain measures of QOL and performance were seen at postintervention and follow-up.
