Exercise Training Guidelines for Multiple Sclerosis, Stroke, and Parkinson Disease: Rapid Review and Synthesis

Velocity-Based Resistance Training on 1-RM, Jump and Sprint Performance: A Systematic Review of Clinical Trials

Weight resistance training (RT) has been shown to positively influence physical performance. Within the last two decades, a methodology based on monitoring RT through movement velocity (also called velocity-based resistance training, VBRT) has emerged. The aim of this PRISMA-based systematic review was to evaluate the effect of VBRT programs on variables related to muscle strength (one-repetition maximum, 1-RM), and high-speed actions (vertical jump, and sprint performance) in trained subjects. The search for published articles was performed in PubMed/MEDLINE, SPORT Discus/EBSCO, OVID, Web of Science, Scopus, and EMBASE databases using Boolean algorithms independently. A total of 22 studies met the inclusion criteria of this systematic review (a low-to-moderate overall risk of bias of the analyzed studies was detected). VBRT is an effective method to improve 1-RM, vertical jump and sprint. According to the results of the analyzed studies, it is not necessary to reach high muscle failure in order to achieve the best training results. These findings reinforce the fact that it is possible to optimize exercise adaptations with less fatigue. Future studies should corroborate these findings in female population.

Exercise Training for Multiple Sclerosis: A Narrative Review of History, Benefits, Safety, Guidelines, and Promotion

Background: There have been significant advances in the medical treatment and management of multiple sclerosis pathogenesis, relapse and disease progression over the past 30 years. There have been advancements in the symptomatic treatment of multiple sclerosis, including management of secondary multiple sclerosis expressions such as walking, cognitive dysfunction, fatigue and depression. Scientific evidence and expert opinion suggest that exercise may be the single most effective non-pharmacological symptomatic treatment for multiple sclerosis. This article presents the historical context of exercise training within the multidisciplinary management of multiple sclerosis. We guide neurologists and healthcare providers on the recommended prescription of exercise and practical, theoretical methods to overcome barriers to exercise. Method: We undertook a critical search of the historical and current literature regarding exercise and multiple sclerosis from the viewpoint of exercise promotion by neurologists and the multidisciplinary care team. Results: We highlight the ever-strengthening body of research indicating that exercise is safe and effective for improving symptoms of multiple sclerosis. Further, exercise training may be necessary for reducing disease progression. Conclusion: We seek to encourage neurologists and specialists in multidisciplinary healthcare teams to prescribe and promote exercise at diagnosis and across all stages of the disease trajectory using prescriptive guidelines as part of comprehensive MS care. Available tools include clinical education to dispel any historical myths related to exercise in multiple sclerosis, clinical exercise guidelines and behaviour change theory to overcome patients barriers to exercise.

Effects of Virtual Reality-Based Intervention on Cognition, Motor Function, Mood, and Activities of Daily Living in Patients With Chronic Stroke: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Background: The efficacy of virtual reality (VR)-based intervention for improving cognition in patients with the chronic stage of stroke is controversial. The aims of this meta-analysis were to evaluate the effect of VR-based training combined with traditional rehabilitation on cognition, motor function, mood, and activities of daily living (ADL) after chronic stroke. Methods: The search was performed in the Cochrane Library (CENTRAL), EBSCO, EMBASE, Medline (OVID), Web of Science databases, PubMed, CINAHL Ovid, and Scopus from inception to May 31, 2021. All included studies were randomized controlled trials (RCTs) examining VR-based intervention combined with traditional rehabilitation for chronic stroke. The main outcomes of this study were cognition, including overall cognition (combined with all cognitive measurement results), global cognition (measured by the Montreal Cognitive Assessment, MoCA, and/or Mini-Mental State Examination, MMSE), and attention/execution. The additional outcomes were motor function, mood, and ADL. Subgroup analyses were conducted to verify the potential factors for heterogeneity. Results: Six RCTs including 209 participants were included for systematic review, and five studies of 177 participants were included in meta-analyses. Main outcome analyses showed large and significant effect size (ES) of VR-based training on overall cognition (g = 0.642; 95% CI = 0.134-1.149; and P = 0.013) and attention/execution (g = 0.695; 95% CI = 0.052-1.339; and P = 0.034). Non-significant result was found for VR-based intervention on global cognition (g = 0.553; 95% CI = -0.273-1.379; and P = 0.189). Additional outcome analyses showed no superiority of VR-based intervention over traditional rehabilitation on motor function and ADL. The ES of VR-based intervention on mood (g = 1.421; 95% CI = 0.448-2.393; and P = 0.004) was large and significant. In the subgroup analysis, large effects for higher daily intensity, higher weekly frequency, or greater dose of VR intervention were found. Conclusion: Our findings indicate that VR-based intervention combined with traditional rehabilitation showed better outcomes for overall cognition, attention/execution, and depressive mood in individuals with chronic stroke. However, VR-based training combined with traditional rehabilitation showed a non-significant effect for global cognition, motor function, and ADL in individuals with chronic stroke.

Yoga Interventions Used for the Rehabilitation of Stroke, Parkinson's Disease, and Multiple Sclerosis: A Scoping Review of Clinical Research

Objectives: The current body of literature was reviewed to compile and describe yoga interventions that have been applied in clinical research and neurologic rehabilitation settings with patients affected by stroke, Parkinson's disease (PD), and multiple sclerosis (MS). Design: Available literature on yoga therapy (YT) was mapped following a five-stage framework to identify key concepts, knowledge gaps, and evidence to inform practice. Publications were identified through Medline, CINAHL, EMBASE, and PsycINFO. Selected studies required subjects with a clinical diagnosis of stroke, PD, and MS to participate in a yoga intervention and have physical, cognitive, and/or psychosocial outcome measures assessed. Results: A total of 50 studies were included in this review. Study characteristics, patient demographics, description of the yoga intervention, reported outcome measures and the main findings were extracted from the studies. Conclusion: Implementing YT in neurorehabilitation can help health care professionals integrate a more holistic approach that addresses the fundamental physical and psychological challenges of living with a chronic and debilitating neurologic disorder. The included studies described yogic interventions consisting of group or individual therapy sessions lasting 60-75 min that were carried out one to three times per week for 8-12 consecutive weeks across all three conditions. All studies described in this scoping review used different yoga protocols confirming the lack of specific interventional parameters available for implementing yoga into the rehabilitation of individuals affected by stroke, PD, or MS.

Anorectal dysfunction in multiple sclerosis patients: A pilot study on the effect of an individualized rehabilitation approach

BACKGROUND:

Anorectal dysfunction (ARD), especially bowel incontinence, frequently compromises the quality of life in multiple sclerosis (MS) patients. The effect of rehabilitation procedures has not been clearly established.

OBJECTIVE:

To determine the effect of an individualized rehabilitation approach on bowel incontinence and anorectal pressures.

METHODS:

MS patients with ARD underwent 6-months of individually targeted biofeedback rehabilitation. High resolution anorectal manometry (HRAM) and St. Mark’s Fecal Incontinence Scores (SMIS) were completed prior to rehabilitation, after 10 weeks of supervised physiotherapy, and after 3 months of self-treatment.

RESULTS:

Ten patients (50%) completed the study. Repeated measures analysis of variance (ANOVA) demonstrated significant improvement in the SMIS questionnaire over time [14.00 baseline vs. 9.70 after supervised physiotherapy vs. 9.30 after self-treatment (p = 0.005)]. No significant improvements over time were noted in any HRAM readings: maximal pressure [49.85 mmHg baseline vs. 57.60 after supervised physiotherapy vs. 60.88 after self-treatment (p = 0.58)], pressure endurance [36.41 vs. 46.89 vs. 49.95 (p = 0.53)], resting pressure [55.83, vs 52.69 vs. 51.84 (p = 0.704)], or area under the curve [230.0 vs. 520.8 vs. 501.9 (p = 0.16)].

CONCLUSIONS:

The proposed individualized rehabilitation program supports a positive overall effect on anorectal dysfunction in MS patients.

Do internet resources align with exercise training and physical activity guidelines for people with multiple sclerosis?

Background

Exercise training and lifestyle physical activity have been identified as evidence-based approaches for improving symptoms and quality of life among persons with multiple sclerosis (MS). Such evidence supported the development of physical activity guidelines (PAGs) for people with MS. The goal of such guidelines involved broad dissemination and uptake, as there is substantial evidence for low rates of participation in exercise training and physical activity in this population.

Objective

The current study evaluated the quality and consistency of information on webpages for physical activity against the established PAGs for people with MS.

Method

The search was conducted in September 2020 using the Google search engine for webpages containing physical activity information for people with MS. We evaluated the webpages with a list of 18 guidelines for adults with MS based on recommendations from three resources.

Results

The search yielded 157 webpages, of which 27 met the inclusion criteria. On average, webpages accurately addressed only 5 of the 18 guidelines. The most commonly addressed guidelines involved MS-specific symptom identification (n = 26), and example modalities for aerobic (n = 20) and strength (n = 16) training.

Conclusion

Many online recourses regarding physical activity and exercise training for MS were either inconsistent with the established PAGs or did not address the guidelines.

Consumer experience of a flexible exercise participation program (FEPP) for individuals with multiple sclerosis: A mixed-methods study

BACKGROUND AND PURPOSE

The flexible exercise participation program (FEPP) is a novel intervention developed to enable individuals with multiple sclerosis (MS) participate and progress in an exercise or sport of their choice. The FEPP is underpinned by guidelines on aerobic exercise for individuals with MS and is supported by a physiotherapist using behaviour change techniques. As part of a FEPP feasibility trial, the aim of this nested study was to explore the experience of participation in the FEPP from the perspective of individuals with MS. The objectives were to (i) determine the acceptability of the FEPP and (ii) identify recommendations for improvement.

METHODS

A mixed methods study using a sequential explanatory design was conducted. Part I consisted of a quantitative participant survey. Survey data were analysed descriptively using SPSS and informed the protocol for part II - qualitative interviews. Interview data were analysed thematically using NVivo. Part III consisted of integration of quantitative and qualitative data to allow greater explanation of survey responses. Individuals with MS who had participated in the FEPP feasibility trial were invited to take part in the study.

RESULTS

The FEPP was highly acceptability to the 10 participants. Five themes emerged to describe the experience of participating in the FEPP: (i) exploring exercise boundaries, (ii) measuring energy, (iii) acknowledging accountability, (iv) adjusting to exercising in a pandemic and (v) sustaining participation. Recommendations for improving the FEPP included changes to energy level monitoring and incorporation of peer support mechanisms.

DISCUSSION

Participants found the FEPP highly acceptable and valued the flexibility to choose their own activity and the health professional support. Based on participant recommendations, future versions of the FEPP will include daily rather than weekly monitoring of exercise and peer support to further enable individuals with MS to find the right balance with exercise and sport.

Exercise and Sports Science Australia (ESSA) position statement on exercise for people with mild to moderate multiple sclerosis

OBJECTIVES

Multiple sclerosis (MS), the most common chronic and progressive neurological condition of the central nervous system, affects 26,000 Australian adults. Exercise training has beneficial effects on MS-related impairments including reduced muscular strength, poor aerobic capacity and impaired mobility, and in consequence can improve quality of life. This Position Statement provides evidence-based recommendations for exercise prescription and delivery of exercise training for people with MS with mild to moderate disability.

DESIGN AND METHODS

Synthesis of published works within the field of exercise training in MS.

RESULTS

Exercise provides many benefits to people with MS. There is strong evidence that resistance and aerobic training, performed 2 to 3 times per week at a moderate intensity, are safe and can improve muscle strength, cardiorespiratory fitness, balance, fatigue, functional capacity, mobility and quality of life in people with MS with mild to moderate disability (Expanded Disease Severity Scale (EDSS) ≤ 6.5). However, the evidence for those with severe disability (EDSS >6.5) is less clear. The effects of exercise on MS pathogenesis, central nervous structures and other outcomes such as depression and cognitive impairment, have not been adequately investigated. Effective exercise interventions to improve balance, joint contractures and reduce falls in people with MS are also urgently needed as well as investigations of long-term (≥1 year) effects of exercise training.

CONCLUSIONS

Resistance and aerobic training exercises are effective to alleviate some characteristic signs and symptoms in MS and should be supplemented by balance exercise to prevent falls. Exercise training programs should be prescribed and delivered by qualified exercise professionals. It is important to recognise and accommodate exercise-associated complications such as fatigue and heat sensitivity.

Acute Cardiovascular Responses to Self-selected Intensity Exercise in Parkinson's Disease

Parkinson's disease patients frequently present cardiovascular dysfunction. Exercise with a self-selected intensity has emerged as a new strategy for exercise prescription aiming to increase exercise adherence. Thus, the current study evaluated the acute cardiovascular responses after a session of aerobic exercise at a traditional intensity and at a self-selected intensity in Parkinson's disease patients. Twenty patients (≥ 50 years old, Hoehn & Yahr 1-3 stages) performed 3 experimental sessions in random order: Traditional session (cycle ergometer, 25 min, 50 rpm, 60-80% maximum heart rate); Self-selected intensity: (cycle ergometer, 25 min, 50 rpm with self-selected intensity); and Control session (resting for 25 min). Before and after 30 min of intervention, brachial and central blood pressure (auscultatory method and pulse wave analysis, respectively), cardiac autonomic modulation (heart rate variability), and arterial stiffness (pulse wave analysis) were evaluated. Brachial and central systolic and diastolic blood pressure, heart rate, and the augmentation index increased after the control session, whereas no changes were observed after the exercise sessions (P<0.01). Pulse wave velocity and cardiac autonomic modulation parameters did not change after the three interventions. In conclusion, a single session of traditional intensity or self-selected intensity exercises similarly blunted the increase in brachial and central blood pressure and the augmentation index compared to a non-exercise control session in Parkinson's disease patients.

Home-Based Exercise Training in Multiple Sclerosis: A Systematic Review with Implications for Future Research

BACKGROUND

Substantial evidence supports the benefits of supervised exercise training (ET) in people with multiple sclerosis (MS). However, there are limitations such as transportation problems preventing physical activity for some people with MS. One opportunity for increasing physical activity participant in people with MS is home-based exercise training (HBET), yet we are unaware of a systematic review of HBET in people with MS. We undertook a systematic review for enhancing the knowledge about HBET in people with MS.

METHODS

To identify eligible studies, we included the medical subject headings (MeSH) keywords including 'multiple sclerosis' OR 'MS' OR 'degenerative nerve disease' AND 'home-based exercise' OR 'home-based training' OR 'home-based balance training' OR 'home-based rehabilitation' OR 'physical telerehabilitation' OR 'home-based walking' OR 'home-based step training.' Studies were included in this review that examined the effect of HBET in people with MS, were written in English, and available in full-text.

RESULTS

According to inclusion and exclusion criteria, 24 studies were judged eligible to be included in this systematic review. The results indicated that a total number of 10 studies had mainly implemented combined ET interventions. Balance and aerobic ET had been included in 5 studies. Three studies had further administered resistance ET interventions and one study had applied exergaming. Moreover, 13 studies had focused on the effects of ET on physical fitness, one article had reflected on the impact of ET on fatigue, and nine cases had included fatigue, quality of life, and fitness as outcome measures.

CONCLUSIONS

Home-based ET, 2-7 times per week, is beneficial, feasible, and safe in people with MS. Nevertheless, there were notable limitations, including (a) adherence to interventions, which needs to be addressed in future studies, and (b) disability-related outcomes which should be considered in future HBET studies.

Safety of exercise training in multiple sclerosis: a protocol for an updated systematic review and meta-analysis

BACKGROUND

There has been an exponential growth in the number of clinical research studies regarding exercise training in multiple sclerosis, and literature reviews and meta-analyses have documented the many benefits of exercise training. This research further requires careful review for documenting the safety of exercise training in multiple sclerosis, as clarity on safety represents a major hurdle in the clinical prescription of exercise behaviour.

OBJECTIVES

To enhance understanding of the feasibility of exercise in multiple sclerosis, we (1) provide a protocol of a systematic review and meta-analysis that summarises rates and risks of clinical relapse, adverse events (i.e., an unfavourable outcome that occurs during the intervention delivery time period), and serious adverse events (i.e., an untoward occurrence that results in death or is life threatening, requires hospitalisation, or results in disability during the intervention delivery time period), as well as retention, adherence, and compliance, from randomised controlled trials of exercise training in persons with multiple sclerosis; and (2) identify moderators of relapse, adverse events, and serious adverse event rates.

METHODS

Eight field-relevant databases will be searched electronically. Studies that involve a randomised controlled trial of exercise training (with non-exercise, non-pharmacological, comparator), report on safety outcomes, and include adults with multiple sclerosis will be included. Rates and relative risks of the three primary outcomes (relapse, adverse event, and serious adverse event) will be calculated and reported each with standard error and 95% confidence interval. Random-effects meta-analysis will estimate mean population relative risk for outcomes. Potential sources of variability, including participant characteristics, features of the exercise stimulus, and comparison condition, will be examined with random-effects meta-regression with maximum likelihood estimation.

DISCUSSION

The results from this systematic review and meta-analysis will inform and guide healthcare practitioners, researchers, and policymakers on the safety of exercise training in persons with multiple sclerosis. Where possible, we will identify the impact of exercise type, exercise delivery style, participant disability level, and the prescription of exercise guidelines, on the safety of exercise training. The result will identify critical information on the safety of exercise in persons with multiple sclerosis, while also identifying gaps in research and setting priorities for future enquiries.

Strength training for people with multiple sclerosis and the current recommendations

Recent guidelines recommend strength and conditioning training for patients with multiple sclerosis (MS). This article evaluates and summarises four systematic reviews examining strength training for people with MS and examines if these reviews substantiate these current guidelines.

Cardiovascular, perceived exertion and affective responses during aerobic exercise performed with imposed and a self-selected intensity in patients with Parkinson's disease

BACKGROUND

Exercise with self-selected intensity (SSI) has emerged as a new strategy for exercise prescription aiming to increase exercise adherence in Parkinson's disease (PD).

OBJECTIVE

We compared the cardiovascular, perceived exertion and affective responses during traditional aerobic exercise and with SSI in PD.

METHODS

Twenty patients with PD performed two aerobic exercise sessions in random order with an interval of at least 72 h between them: Traditional session (cycle ergometer, 25 min, 50 rpm) with imposed intensity (II) (60-80% maximum heart rate [HR]) and SSI: (cycle ergometer, 25 min, 50 rpm) with SSI. The HR (Polar V800 monitor), systolic blood pressure (auscultatory method), rating of perceived exertion (Borg scale 6-20) and affective responses (feeling scale) were assessed during the exercise at 8th and 18th minute. The Generalized Estimating Equation Model was used for comparison between both sessions (P < 0.05).

RESULTS

The exercise intensity was not significantly different between both exercise sessions (8th minute: II -76.3±1.0 vs. SSI -76.5±1.3 % of maximal HR; 18th minute: II -78.9±0.9 vs. SSI -79.1±1.3 % of maximal HR, p = 0.93). Blood pressure, perceived exertion and affective responses were also not significantly different between both sessions (P > 0.05).

CONCLUSIONS

Cardiovascular and psychophysiological responses were not different during aerobic exercise performed with II and with SSI in patients with PD.

Strategies for maintaining dynamic balance in persons with neurological disorders during overground walking

Maintaining a stable gait requires a dynamic balance control, that can be altered in persons with Multiple Sclerosis (MS), Stroke (ST), and Parkinson's disease (PD). The understanding of the strategy for Center of Mass (CoM) positioning adopted by patients during walking is important to be able to program treatments aimed at improving gait control and preventing falls. Forty-four persons with a mild-to-moderate neurological disorder (20 with MS, 14 with ST, 10 with PD) underwent clinical examination and gait analysis. Ten Healthy Subjects (HS) walking at matched speed provided the normative data. Dynamic balance was assessed using the margin of stability (MoS). It was calculated as the distance between the extrapolated Center of Pressure and the extrapolated CoM at mid-stance. The MoS values for lower limbs were calculated in patients and compared with speed-matched values of HS. Persons with neurological disorder showed increased MoS in the medio-lateral direction with respect to HS. Within-group comparison analysis showed a symmetry between lower limbs in HS (Mean (95%CI) [mm], dominant vs non-dominant limb, 43.3 (31.9-54.6) vs 42.9 (28.8-56.9)) and PD (less affected vs more affected limb, 71.1 (59.8-82.5) vs 72.5 (58.5-86.6)), while a significant asymmetry was found in MS (54.4 (46.4-62.4) vs 81.1 (71.2-91.1)) and ST (52.1 (42.6-61.7) vs 74.7 (62.8-86.6)) participants. The history of falls was comparable among PD, MS, and ST groups, and the MoS in the frontal plane showed a strong correlation with these records. Objective assessment of MoS revealed pathology-specific strategies showing different impacts in MS, ST, and PD on the ability to control CoM information to manage the balance between limbs during gait. MoS evaluation will provide useful information to address a tailored rehabilitation program and to monitor disease progression.

Design and Evaluation of User-Centered Exergames for Patients With Multiple Sclerosis: Multilevel Usability and Feasibility Studies

BACKGROUND

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system. Patients with MS experience a wide range of physical and cognitive dysfunctions that affect their quality of life. A promising training approach that concurrently trains physical and cognitive functions is video game-based physical exercising (ie, exergaming). Previous studies have indicated that exergames have positive effects on balance and cognitive functions in patients with MS. However, there is still a need for specific, user-centered exergames that function as a motivating and effective therapy tool for patients with MS and studies investigating their usability and feasibility.

OBJECTIVE

The aim of this interdisciplinary research project is to develop usable and feasible user-centered exergames for the pressure-sensitive plate Dividat Senso by incorporating theoretical backgrounds from movement sciences, neuropsychology, and game research as well as participatory design processes.

METHODS

Focus groups (patients and therapists) were set up to define the user-centered design process. This was followed by the field testing of newly developed exergame concepts. Two sequential usability and feasibility studies were conducted on patients with MS. The first study included a single exergaming session followed by measurements. Between the first and second studies, prototypes were iterated based on the findings. The second study ran for 4 weeks (1-2 trainings per week), and measurements were taken before and after the intervention. For each study, participants answered the System Usability Scale (SUS; 10 items; 5-point Likert Scale; score range 0-100) and interview questions. In the second study, participants answered game experience-related questionnaires (Flow Short Scale [FSS]: 13 items; 7-point Likert Scale; score range 1-7; Game Flow questionnaire: 17 items; 6-point Likert Scale; score range 1-6). Mixed methods were used to analyze the quantitative and qualitative data.

RESULTS

In the first study (N=16), usability was acceptable, with a median SUS score of 71.3 (IQR 58.8-80.0). In the second study (N=25), the median SUS scores were 89.7 (IQR 78.8-95.0; before) and 82.5 (IQR 77.5-90.0; after), and thus, a significant decrease was observed after training (z=-2.077; P=.04; r=0.42). Moreover, high values were observed for the overall FSS (pre: median 5.9, IQR 4.6-6.4; post: median 5.8, IQR 5.4-6.2) and overall Game Flow Questionnaire (pre: median 5.0, IQR 4.7-5.3; post: median 5.1, IQR 4.9-5.3). A significant decrease was observed in the item perceived importance (FSS: z=-2.118; P=.03; r=0.42). Interviews revealed that user-centered exergames were usable, well accepted, and enjoyable. Points of reference were identified for future research and development.

CONCLUSIONS

The project revealed that the newly developed, user-centered exergames were usable and feasible for patients with MS. Furthermore, exergame elements should be considered in the development phase of user-centered exergames (for patients with MS). Future studies are needed to provide indications about the efficacy of user-centered exergames for patients with MS.

Effects of task-oriented training combined with aerobic training on serum BDNF, GDNF, IGF-1, VEGF, TNF-α, and IL-1β levels in people with Parkinson's disease: A randomized controlled study

INTRODUCTION

Parkinson's disease (PD) is a chronic neurodegenerative disease characterized by the death of dopaminergic neurons in the substantia nigra pars compacta. Exercise training, which is incorporated both goal-based training such as task-oriented training (TOT) and aerobic training (AT), has been suggested to induce neuroprotection. However, molecular mechanisms which may underlie exercise-induced neuroprotection are still largely unknown. Thus, the aim of the present study was to investigate the effects of TOT combined with AT (TOT-AT) on serum brain-derived neurotrophic factor (BDNF), glial cell-derived growth factor (GDNF), insulin-like growth factor-1 (IGF-1), vascular endothelial growth factor (VEGF), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) levels in people with PD (PwPD).

METHODS

Forty PwPD were randomized into 8-week of either exercise group (n = 20) or control group (n = 20). The exercise group received TOT-AT while the control group received only AT. Serum BDNF, GDNF, IGF-1, VEGF, TNF-α, and IL-1β levels determined with ELISA were assessed at baseline and after training.

RESULTS

A total of 29 PwPD completed this study. Our results showed no significant change in the serum BDNF, GDNF, IGF-1, VEGF, TNF-α, and IL-1β levels in both groups. After the intervention period, no significant difference was observed between the groups regarding the serum BDNF, GDNF, IGF-1, VEGF, TNF-α, and IL-1β levels.

CONCLUSION

TOT-AT could not be an effective exercise method for changing serum concentrations of BDNF, GDNF, IGF-1, VEGF, TNF-α, and IL-1β in the rehabilitation of PD.

Effect of dual-task training on balance in patients with multiple sclerosis: A systematic review and meta-analysis

OBJECTIVE

To evaluate the effects of dual-task training on static and dynamic balance in patients with multiple sclerosis.

DATA SOURCES

PubMed/MEDLINE, EMBASE, Scopus, and PEDro databases were searched from inception to March 1, 2021.

METHODS

This study was conducted in agreement with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Two reviewers assessed studies for inclusion and extracted data. We used the Physiotherapy Evidence Database scale to evaluate the methodological quality and the risk-of-bias. Randomized clinical trial data were pooled for the meta-analysis. The effect sizes and 95% confidence interval (CI) were calculated by random-effect models. Egger regression and Begg-Mazumdar rank correlation test were used for publication bias.

RESULTS

A total of 13 studies involving 584 patients (42.3 ± 9 years mean ± SD; 377 females) met the inclusion criteria for the systematic review, while nine were included in the meta-analysis. People who received dual-task training interventions showed significant improvements in the Timed Up & Go test 0.44 [(95% CI = 0.22; 0.65), P-value<0.001], and in the Berg Balance scale 0.46 [(95% CI = 0.07; 0.85), P-value = 0.02]. Low and moderate heterogeneity between the studies was found for the Timed Up & Go test and the Berg Balance scale, respectively.

CONCLUSION

The findings from the current meta-analysis support dual-task training as a beneficial therapy for improving dynamic balance and functional mobility in patients with multiple sclerosis. The limited number of studies that investigated static balance performance after dual-task training do not currently allow us to draw a conclusion about any possible improvements in this ability.

Corticospinal excitability and motor representation after long-term resistance training

It is poorly understood how the central nervous system adapts to resistance training, especially after years of exposure. We compared corticospinal excitability and motor representation assessed with transcranial magnetic stimulation (TMS) between long-term resistance trained (LRT, ≥3 years) versus untrained (UNT) males (n = 15/group). Motor-evoked potentials (MEPs) were obtained from the biceps brachii during isometric elbow flexion. Stimulus-response curves were created at the hotspot during 10% maximum voluntary torque (MVT) contractions. Maximum peak-to-peak MEP amplitude (MEPmax) was acquired with 100% stimulator output intensity, whilst 25%-100% MVT was produced. Maps were created during 10% MVT contractions, with an individualised TMS intensity eliciting 20% MEPmax at the hotspot. LRT had a 48% lower stimulus-response curve slope than UNT (p < .05). LRT also had a 66% larger absolute map size, although TMS intensity used for mapping was greater in LRT versus UNT (48% vs. 26% above active motor threshold) to achieve a target 20% MEPmax at the hotspot, due to the lower slope of LRT. Map size was strongly correlated with the TMS intensity used for mapping (r = 0.776, p < .001). Once map size was normalised to TMS intensity, there was no difference between the groups (p = .683). We conclude that LRT had a lower stimulus-response curve slope/excitability, suggesting higher neural efficiency. TMS map size was overwhelmingly determined by TMS intensity, even when the MEP response at the hotspot was matched among individuals, likely due to larger current spread with higher intensities. Motor representation appears similar between LRT and UNT given no difference in the normalised map size.

Virtual reality for limb motor function, balance, gait, cognition and daily function of stroke patients: A systematic review and meta-analysis

AIMS

To explore the beneficial effects of virtual reality (VR) interventions on upper- and lower-limb motor function, balance, gait, cognition and daily function outcomes in stroke patients.

DESIGN

A systematic review and meta-analysis of randomized controlled trials.

DATA SOURCES

English databases (PubMed, EMBASE, the Cochrane Library, CINAHL, Web of Science, Physiotherapy Evidence Database, ProQuest Dissertations and Theses) and Chinese databases (Chinese BioMedical Literature Service System, WANFANG, CNKI) and the Clinical Trial Registry Platform were systematically searched from inception until December 2019. Additionally, reference lists of the included studies were manually searched.

REVIEW METHODS

The methodological quality of studies was scored with the Cochrane 'risk-of-bias tool' and PEDro scale from the Physiotherapy Evidence Database by two independent evaluators.

RESULTS

In total, 87 studies with 3540 participants were included. Stroke patients receiving VR interventions showed significant improvements in Fugl-Meyer assessment of Upper Extremity, Action Research Arm Test, Wolf Motor Function Test, Fugl-Meyer Assessment of Lower Extremity, Functional Ambulation Classification, Berg Balance Scale, Time Up and Go, Velocity, Cadence, Modified Barthel Index and Functional Independence Measure. However, differences between VR intervention and traditional rehabilitation groups were not significant for Box-Block Test, 10 m Walk Test, Auditory Continuous Performance Test, Mini-Mental State Examination and Visual Continuous Performance Test.

CONCLUSION

This review suggests that VR interventions effectively improve upper- and lower-limb motor function, balance, gait and daily function of stroke patients, but have no benefits on cognition.

IMPACT

This review identified the positive effects of VR-assisted rehabilitation on upper- and lower-limb motor function, balance, gait and daily function of stroke patients. And, we verified the duration of VR intervention affects some health benefits. The benefit of VR on cognitive function requires further investigation through large-scale multicentre RCTs.

Guidelines on exercise testing and prescription for patients at different stages of Parkinson's disease

BACKGROUND

Exercise is highly recommended in patients with Parkinson's disease (PD). Exercise-induced amelioration of motor, non-motor, and drug-induced symptoms are widely known. However, specific guidelines on exercise testing and prescription in PD are lacking.

OBJECTIVE

This study reviews the literature on exercise-based approaches to the management of symptoms at each stage of the disease and evaluate: (1) the most suitable clinical exercise testing; (2) training programs based on testing outcomes and PD stage; (3) the effects of exercise on antiparkinsonian drugs and to suggest the most effective exercise-medication combination.

METHODS

A systematic search was conducted using the databases MEDLINE, Google Scholar and, Cochrane Library using "Parkinson's Disease AND Physical therapy", "Training AND Parkinson", "Exercise", "Exercise AND Drug" as key words. In addition, references list from the included articles were searched and cross-checked to identify any further potentially eligible studies.

RESULTS

Of a total of 115 records retrieved, 50 (43%) were included. From these, 23 were included under the rubric "exercise testing"; 20 focused on the effectiveness of different types of exercise in PD motor-functional symptoms and neuroprotective effects, throughout disease progression, were included under the rubric "training protocol prescription"; and 7 concern the rubric "interaction between exercise and medication", although none reported consistent results.

CONCLUSIONS

Despite the lack of standardized parameters for exercise testing and prescription, all studies agree that PD patients should be encouraged to regularly train according to their severity-related limitations and their personalized treatment plan. In this manuscript, specific guidelines for tailored clinical testing and prescription are provided for each stage of PD.

Changing Behaviour towards Aerobic and Strength Exercise (BASE): Design of a randomised, phase I study determining the safety, feasibility and consumer-evaluation of a remotely-delivered exercise programme in persons with multiple sclerosis

BACKGROUND

Multiple sclerosis is a chronic progressive neurological disease. Evidence attests to the benefits of exercise, guidelines for exercise in multiple sclerosis are available. Remote-delivery of exercise adherence programmes based on the exercise guidelines require urgent testing.

AIMS

The design, and outcomes of Behaviour towards Aerobic and Strength Exercise in MS (BASE-MS), a remotely-delivered exercise training study based principles of behaviour change, will further evaluate the remote-delivery of the current exercise guidelines.

METHODS

BASE is a 4-month clinically relevant randomised controlled trial to explore the delivery of a remotely supervised, guidelines-based exercise programme for persons with multiple sclerosis, underpinned by principles of health behaviour change. Initially, 72 persons with mild to moderate multiple sclerosis will be randomised in a 1:1:1 allocation to receive the BASE programme, or act as controls continuing usual care. On programme completion, exercise participants will be further randomised to an optimised adherence treatment or usual adherence. Our online survey assesses the primary outcome of exercise participation, and secondary outcomes of symptoms, and correlates of behaviour change at baseline, month four, month five and month eleven. Online surveys will capture coach and participant feedback to identify the contexts, mechanisms and outcomes of BASE implementation.

CONCLUSIONS

The research and clinical landscape for MS management must remain in-step with public health and health communication. BASE tests the remote-delivery of the current exercise guidelines for exercise in persons with MS. Safety, feasibility and evaluative outcomes will provide rich data for future remote-delivery of exercise in neurological conditions.

The knowns and unknowns of neural adaptations to resistance training

The initial increases in force production with resistance training are thought to be primarily underpinned by neural adaptations. This notion is firmly supported by evidence displaying motor unit adaptations following resistance training; however, the precise locus of neural adaptation remains elusive. The purpose of this review is to clarify and critically discuss the literature concerning the site(s) of putative neural adaptations to short-term resistance training. The proliferation of studies employing non-invasive stimulation techniques to investigate evoked responses have yielded variable results, but generally support the notion that resistance training alters intracortical inhibition. Nevertheless, methodological inconsistencies and the limitations of techniques, e.g. limited relation to behavioural outcomes and the inability to measure volitional muscle activity, preclude firm conclusions. Much of the literature has focused on the corticospinal tract; however, preliminary research in non-human primates suggests reticulospinal tract is a potential substrate for neural adaptations to resistance training, though human data is lacking due to methodological constraints. Recent advances in technology have provided substantial evidence of adaptations within a large motor unit population following resistance training. However, their activity represents the transformation of afferent and efferent inputs, making it challenging to establish the source of adaptation. Whilst much has been learned about the nature of neural adaptations to resistance training, the puzzle remains to be solved. Additional analyses of motoneuron firing during different training regimes or coupling with other methodologies (e.g., electroencephalography) may facilitate the estimation of the site(s) of neural adaptations to resistance training in the future.

Reference Values for Isometric, Dynamic, and Asymmetry Leg Extension Strength in Patients with Multiple Sclerosis

Having recognized the value of resistance training in patients with multiple sclerosis (PwMS), there are a lack of lower limb normative reference values for one repetition maximum (1RM) and maximal voluntary isometric contraction (MVIC) in this population. Hence, the purposes of this study were to provide reference values for 1RM and MVIC of knee extensors in PwMS across the disability spectrum and to examine knee extension strength asymmetry. Three hundred and ninety PwMS participated in the study, performing MVIC and 1RM tests of bilateral (both legs together at once) and unilateral (each leg singly) knee extensors. There was no difference in 1RM according to the disease course of MS, but there was according to the degree of neurological disability, being more preserved in those with a lower degree of disability. MVIC tends to be higher in patients with relapsing-remitting MS respect those with progressive MS, and in patients with lower levels of neurological disability. Asymmetry above the values considered normal in 1RM was present in 20-60% of patients and 56-79% in the MVIC test, depending on the type of MS and tended to be lower in those with less disability. Reference values are given by quartiles for 1RM, MVIC, and asymmetry.

Neurorehabilitation in dystonia: a holistic perspective

Rehabilitation for isolated forms of dystonia, such as cervical or focal hand dystonia, is usually targeted towards the affected body part and focuses on sensorimotor control and motor retraining of affected muscles. Recent evidence, has revealed people who live with dystonia experience a range of functional and non-motor deficits that reduce engagement in daily activities and health-related quality of life, which should be addressed with therapeutic interventions. These findings support the need for a holistic approach to the rehabilitation of dystonia, where assessment and treatments involve non-motor signs and symptoms, and not just the dystonic body part. Most studies have investigated Cervical Dystonia, and in this population, it is evident there is reduced postural control and walking speed, high fear of falling and actual falls, visual compensation for the impaired neck posture, and a myriad of non-motor symptoms including pain, fatigue, sleep disorders and anxiety and depression. In other populations of dystonia, there is also emerging evidence of falls and reduced vision-related quality of life, along with the inability to participate in physical activity due to worsening of dystonic symptoms during or after exercise. A holistic approach to dystonia would support the management of a wide range of symptoms and signs, that if properly addressed could meaningfully reduce disability and improve quality of life in people living with dystonia.

Nordic walking for people with relapsing-remittent multiple sclerosis: A case series study

BACKGROUND

Patients with multiple sclerosis (MS) show fatigue, impaired gait and decreased functional mobility, which lead to a low quality of life (QoL). Low-cost and easy to perform exercise modalities having a positive impact on the aforementioned symptoms are needed. The performance of Nordic Walking (NW) could be a useful rehabilitation strategy but, to our knowledge, no study has been published in this regard as yet. This case series study aims at providing information regarding the usefulness and impact of a three-month NW program on self-perceived fatigue, functional mobility, physical fitness and QoL on a group of people with mild relapsing-remitting MS.

METHODS

A case series study with multiple assessments was performed. Three data collection points at 1-week intervals for three weeks were done at baseline. The intervention consisted of a 12-weeks NW program with a total of four measurement occasions, one every three weeks. The Fatigue Severity Scale (FSS), the Timed up and Go test (TUG), the 6-Minute Walk test (6MWT) and the Multiple Sclerosis Impact Scale (MSIS-29), were used to assess the outcomes of the program on the participants' self-perceived fatigue, functional mobility, physical fitness and QoL, respectively.

RESULTS

Of the 14 participants who volunteered for the study, five completed at least 80% of the planned sessions and were included in the final analysis. The intervention did not have a clinical significant impact on the participants' fatigue while its impact on their QoL showed mixed results. Positive trends were found for all the participants in their functional mobility and physical fitness. Regarding functional mobility, clinically important changes were observed in three participants. None of the observed changes in physical fitness achieved clinical significance.

CONCLUSION

A 12-week Nordic walking program did not appear to be particularly feasible and had little impact on the functional levels on a group of people with mild relapsing-remitting MS. Given that beneficial effects were seen in some participants, and taken into account the low adherence rate observed, future studies should explore the feasibility of NW programs performed under different environmental conditions (i.e. outdoors) and including motivational strategies aimed at increasing participation.

High Frequency and Intensity Rehabilitation in 641 Subacute Ischemic Stroke Patients

OBJECTIVES

To determine the effects of exergaming on quality of life (QoL), motor, and clinical symptoms in subacute stroke patients.

DESIGN

A pseudorandomized controlled trial, using a before-after test design.

SETTING

University hospital.

PARTICIPANTS

Subacute, ischemic stroke outpatients (N=3857), 680 of whom were randomized and 641 completed the study.

INTERVENTIONS

We determined the effects of 5 times a week twice daily (EX2; 50 sessions; n=286) and once daily (EX1; 25 sessions; n=272) exergaming and low-intensity standard care (control [CON]; 25 sessions; n=83) on clinical, mobility, blood pressure (BP), and QoL outcomes.

MAIN OUTCOME MEASURES

The primary outcome was Modified Rankin Scale. Secondary outcomes were activities of daily living, 5 aspects of health-related QoL, Beck Depression Inventory, 6-minute walk test (6MWT), Berg Balance Scale (BBS), and static balance (center of pressure).

RESULTS

During exercise, the peak heart rate was 134, 134, and 126 beats per minute in the EX2, EX1, and CON groups, respectively. mRS improved similarly in the EX2 (-1.8; effect size, d=-4.0) and EX1 (-1.4; d=-2.6) groups, but more than in the CON group (-0.7; d=-0.6). QoL, Barthel Index, BBS, 6MWT, and standing posturography improved more in the EX2 group and the same in the EX1 and CON groups. Systolic and diastolic resting BP decreased more in the EX2 and EX1 groups than in the CON group. The intervention effects did not differ between men (n=349) and women (n=292).

CONCLUSIONS

Twice daily compared with once daily high-intensity exergaming or once daily lower intensity standard care produced superior effects on clinical and motor symptoms, BP, and QoL in male and female subacute ischemic stroke participants.

Step-rate threshold for physical activity intensity in Parkinson's disease

OBJECTIVES

To examine the relationship between step-rate and energy expenditure during treadmill walking in persons with PD and then further develop a step-rate cut-point for moderate-to-vigorous physical activity (MVPA) for persons with PD.

MATERIALS AND METHODS

The sample consisted of 30 persons with mild-to-moderate PD and 30 controls matched by age and sex. Participants performed a 6-minute bout of over-ground walking at comfortable speed, and then completed three, 6-minute bouts of treadmill walking at 13.4 m/min slower, comfortable, and 13.4 m/min faster than comfortable speeds. The three treadmill speeds were based on the initial over-ground walking speed. The total number of steps per treadmill walking bout was recorded using a hand-tally counter, and energy expenditure was measured using a portable, indirect spirometry system.

RESULTS

The results indicated a strong association between step-rate and energy expenditure for persons with PD (R²  = .92) and controls (R²  = .92). The analyses further indicated a steeper slope of the association for persons with PD compared with controls (t(58) = -1.87, P < .05), resulting in a lower step-rate threshold (t(58) = 2.19, P < .05) for persons with PD (~80 steps·per minutes) than controls (~93 steps·per minutes).

CONCLUSION

Collectively, these results support the application of this disease-specific step-rate threshold for MVPA among persons with PD. This has important implications for physical activity promotion, prescription, and monitoring using accelerometers and pedometers for persons with PD to manage health and symptoms of PD.

Promoting Physical Activity via Telehealth in People With Parkinson Disease: The Path Forward After the COVID-19 Pandemic?

OBJECTIVE

There is mounting evidence in support of exercise and physical activity as a first-line approach to managing symptoms and potentially altering disease progression in people with Parkinson disease (PD). For many patients, a critical gap is the need for expert guidance to overcome barriers, set realistic goals, and provide personalized advice to optimize exercise uptake and adherence. The purpose of this case report is to describe a physical activity coaching program (Engage-PD) for individuals newly diagnosed with PD and to highlight rapid modifications made to this program in response to the COVID-19 pandemic.

METHODS (CASE DESCRIPTION)

Engage-PD is a single cohort implementation study of a coaching intervention grounded in self-determination theory being conducted at Columbia University Parkinson's Foundation Center of Excellence in New York City, NY (USA), the early epicenter of the COVID-19 pandemic in the United States. The project was uniquely positioned to be adapted to telehealth delivery and to address an immediate need for support and guidance in the home environment, including people with early-mid-stage PD. Participants completed baseline and follow-up (3 months) assessments and participated in up to 4 coaching sessions, all delivered via a telehealth platform. The intervention incorporated 1:1 coaching, goal-setting, physical activity monitoring, and use of a disease-specific workbook to promote and support safe exercise uptake.

RESULTS

While the program is ongoing, 52 referrals were received and 27 individuals with PD enrolled in the first 2 months of the pandemic for a recruitment rate of 52%. Although direct comparisons with pre-coronavirus recruitment are difficult due to the recency of the Engage-PD implementation study, this recruitment rate was larger than expected, which may have been due to several factors (eg, most patients had limited, if any, access to in-person programs and therapy services during this time, so the Engage program filled an immediate need to provide exercise and activity guidance). There was a wide range of scores for both baseline physical activity and self-efficacy measures.

CONCLUSION

Remotely delivered interventions may serve as a sustainable platform for physical activity coaching programs for people with PD as well as other neurodegenerative diseases.

IMPACT

With the uncertainty brought about by the current pandemic, this case report highlights the opportunity to shift the current model of care for individuals with neurodegenerative diseases such as PD.

Exercise participation and promotion in the multiple sclerosis community; perspectives across varying socio-ecological levels

Purpose: We undertook a qualitative study that explored exercise participation and exercise promotion in the multiple sclerosis (MS) community who live in regional or remote areas of Australia. By simultaneously gathering views from persons with MS, carers, healthcare providers and healthcare managers we aimed to gather unique perspectives which represented views from across socio-ecological levels of MS healthcare.Methods: We used interpretive description methodology, and conducted semi-structured interviews or focus groups with people with MS (n = 28), carers (n = 8), healthcare providers (n = 12) and managers/supervisors of MS healthcare systems (n = 16). Data were analysed using thematic analysis.Results: We identified three themes with 10 subthemes. The first theme was "Factors associated with exercise engagement" for the people with MS, from individual, interpersonal, organisational and community/public policy perspectives. The second theme was "Factors influencing the MS community's promotion of exercise" focusing on carers, healthcare providers and healthcare systems. The third theme was "Motivators to increase exercise promotion" which should be delivered by the MS community across varying socio-ecological levels of healthcare to encourage exercise participation.Conclusion: We identified new evidence on the factors which influence the MS community's promotion of exercise and we now better understand that training on exercise should be provided to the wider MS community, and exercise services should be considered locally and perhaps delivered via teleheath.IMPLICATIONS FOR REHABILITATIONCohesive healthcare campaigns, and clinical guidelines based on empirical evidence should be established for symptom management in MS with a focus on the role of exercise.Symptom management strategies should consider the whole MS community, including patients, carers, healthcare professional and healthcare co-ordinators.Internal factors (e.g., emotion and motivation) and broader factors (e.g., funding and location) must be considered when designing exercise interventions in persons with MS.

Exercise and lifestyle physical activity recommendations for people with multiple sclerosis throughout the disease course

Objectives:

To provide clinicians who treat multiple sclerosis (MS) patients with evidence-based or expert opinion–based recommendations for promoting exercise and lifestyle physical activity across disability levels.

Methods:

The National MS Society (“Society”) convened clinical and research experts in the fields of MS, exercise, rehabilitation, and physical activity to (1) reach consensus on optimal exercise and lifestyle physical activity recommendations for individuals with MS at disability levels 0–9.0 on the Expanded Disability Status Scale (EDSS) and (2) identify and address barriers/facilitators for participation.

Recommendations:

Based on current evidence and expert opinion, the Society makes the following recommendations, endorsed by the Consortium of Multiple Sclerosis Centers:

Finding the right balance with participation in exercise and sport for individuals with multiple sclerosis: protocol for a pre and post intervention feasibility study

INTRODUCTION

Individuals with minimal disability from multiple sclerosis (MS) requested advice on finding the right balance, between too much and too little exercise, when participating in their choice of sport or exercise. To optimise exercise participation during the early stages of the disease, a flexible exercise participation programme (FEPP) has been developed. The FEPP is novel because it provides guidance and support for individuals with MS to participate and progress in their preferred sport or exercise. The primary objective was to assess the feasibility of the FEPP. The secondary objective was to assess the feasibility of a larger trial to demonstrate the efficacy of the FEPP.

METHODS AND ANALYSIS

A stage I feasibility study of the FEPP, using a single group preintervention/post-intervention design, will be conducted with 16 participants with minimal disability from MS (Expanded Disability Status Scale level of 0-3.5). The 12-week FEPP will guide participants to independently participate in their preferred sport or exercise at a location of their choice. Exercise progression will be guided by individual energy levels and a weekly telephone coaching session with a physiotherapist. Participation in exercise or sport will be recorded in parallel with assessment of disease biomarkers (plasma cytokines interleukin (IL)-2, IL-4, IL-6, IL-10, interferon (IFN)-γ and tumour necrosis factor (TNF)), subjective vitality and high-level mobility. Acceptability of the FEPP will be assessed using a sequential explanatory mixed methods design where the findings of a participant survey will inform the interview guide for a series of focus groups.Feasibility of a larger trial will be assessed via process, resources, management and scientific metrics. Progression to a larger trial will depend on the achievement of specified minimum success criteria.

ETHICS AND DISSEMINATION

Ethical approval has been obtained for this study from the James Cook University Human Research Ethics Committee (H7956). Dissemination of findings is planned via peer-reviewed journals, conference presentations and media releases. The protocol date was 21 December 2019, V.1.

TRIAL REGISTRATION NUMBER

The trial is registered with Australian New Zealand Clinical Trials Registry (ANZCTR), ACTRN12620000076976.

Predictors of Multiple Sclerosis Severity Score in Patients with Multiple Sclerosis

Background

Multiple sclerosis (MS) is a demyelinating autoimmune disorder. Several factors have been shown to associate with MS clinical severity. The influence of different lifestyle factors on MS clinical severity as assessed by the Multiple Sclerosis Severity Score (MSSS) was investigated.

Methods

A questionnaire was administered to 128 Kuwaiti MS patients to assess the association of smoking, nutritional supplement use, food allergy, physical activity (PA), and educational level with MSSS. A multiple linear regression model was used to test for associations. Regression model results were adjusted for sex, history of blood transfusion, age at MS onset, and marital status.

Results

Smoking status, passive smoking, and food allergy are not associated with MSSS. Patients with MS with a college education and graduate/professional degrees score, on average, 2.56 lower on the MSSS compared with those with less than a high school education (β= -2.22, P = .045; and β = -2.90, P = .048, respectively). Patients who perform PA score, on average, 2.32 lower on the MSSS compared with those with no PA (moderate exercise, P = .003; rigorous exercise, P = .001), and PA correlated significantly with MSSS outcomes (r² = 0.452, P < .001).

Conclusions

Educational level and PA are significantly associated with reduced MSSS, and both contribute to a less severe MS clinical course. Current MS management protocols should consider lifestyle changes to improve the quality of life of patients with MS.

Exercise and Multiple Sclerosis

Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system (CNS) with an estimated prevalence approaching 1 million adults in the United States. The disease pathogenesis and resulting damage express as dysfunction (e.g., walking and cognitive impairment) and symptoms (e.g., fatigue and depression) that compromise quality of life (QOL) and full participation. There has been a steadily increasing body of research on the outcomes of exercise among persons with MS, and this has accelerated sharply over the past decade. The current chapter provides a review of exercise and its outcomes, safety, and prescription in MS. This chapter initially reviews the evidence for benefits of exercise based principally on meta-analyses and literature reviews. The chapter then reviews evidence on the safety of exercise in MS and lastly provides guidelines for exercise prescription in MS. Collectively, this chapter serves as an overview and reference for researchers and clinicians interested in the benefits, safety, and prescription of exercise in MS.

Efficiency and Patient-Reported Outcome Measures From Clinic to Home: The Human Empowerment Aging and Disability Program for Digital-Health Rehabilitation

Background: The recent exponential growth of Digital Health (DH) in the healthcare system provides a crucial transformation in healthcare, answering to alarming threats related to the increasing number of Chronic Neurological Diseases (CNDs). New long-term integrated DH-care approaches, including rehabilitation, are warranted to address these concerns. Methods: The Human Empowerment Aging and Disability (HEAD) rehabilitation program, a new long-term integrated care including DH-care system, was evaluated in terms of efficiency and patient-reported outcome measures (PROMs) in 107 CND patients (30 with Parkinson's Disease, PD; 32 with Multiple Sclerosis, MS; 45 with stroke in chronic stage). All participants followed 1-month of HEAD rehabilitation in clinic (ClinicHEAD: 12 sessions, 3/week), then 1:3 patient was consecutively allocated to 3-months telerehabilitation at home (HomeHEAD: 60 sessions, 5/week). Efficiency (i.e., adherence, usability, and acceptability) and PROMs (i.e., perceived functioning in real-world) were analyzed. Results: The rate of adherence to HEAD treatment in clinic (≥90%) and at home (77%) was high. Usability of HEAD system was judged as good (System Usability Scale, median 70.00) in clinic and even more at home (median 80.00). Similarly, administering the Technology Acceptance Model 3 questionnaire we found high scores both in clinic/at home (Usefulness, mean 5.39 ± 1.41 SD/mean 5.33 ± 1.29 SD; Ease of use, mean 5.55 ± 1.05 SD/ mean 5.45 ± 1.17 SD, External Control, mean 4.94 ± 1.17 SD/mean 5.07 ± 1.01 SD, Relevance, mean 5.68 ± 1.29 SD/mean 5.70 ± 1.13 SD and Enjoyment, mean 5.70 ± 1.40 SD/mean 6.01 ± 1.08 SD). After ClinicHEAD, participation and autonomy in daily routine was maintained or even ameliorated (PD and stroke > MS). Whereas, increased functionality and participation in the MS group was found only after HomeHEAD intervention. Discussion: Our results suggest that a tele-health-based approach is both feasible and efficient in providing rehabilitation care to CNDs from clinic to home. Increasing and maintaining participation as well as autonomy in daily routine are promising findings that open up scenarios for the continuity of care at home through DH-care for CNDs.

Functional Electrical Stimulation Cycling Exercise for People with Multiple Sclerosis

PURPOSE OF REVIEW

There has been substantial interest in the role of exercise for managing impairments, limitations, and disability progression among persons with multiple sclerosis (MS). Despite established benefits of exercise training for persons who have mild-to-moderate MS, the ability to deliver exercise to persons who experience higher disability remains challenging. One promising approach for exercise in this population is functional electrical stimulation (FES) cycling. This review provides a summary of the current evidence for FES cycling as an exercise training modality in persons with MS with respect to prescription, safety, tolerability, and acute and chronic effects.

RECENT FINDINGS

We searched the literature for studies involving FES cycling exercise in persons with MS published in English up until July 2019. Eight studies were retrieved: two studies examined acute effects, two studies examined chronic effects, and four studies reported on both acute and chronic effects of FES cycling exercise. The overall quality of the studies was low, with only one, small, randomized controlled trial (RCT). There is limited but promising evidence for the application of FES cycling exercise among persons with MS who have moderate-to-severe disability. Participants were capable of engaging in regular FES cycling exercise (~ 30 min, 2-3×/week), with few, mild adverse events experienced. Preliminary evidence from small, mostly uncontrolled trials supports the potential benefits of FES cycling on physiological fitness, walking mobility, and symptoms of fatigue and pain. High-quality RCTs of FES cycling exercise are necessary for providing recommendations for integrating exercise training in the management of advanced MS.

The priorities of neurologists for exercise promotion in comprehensive multiple sclerosis care

BACKGROUND

Fewer than 20% of persons with multiple sclerosis (MS) engage in sufficient amounts of exercise for experiencing health and wellness benefits. Neurologists have a powerful and influential relationship among patients, highlighting the potential for the patient-provider interaction to be a gateway for promoting exercise behavior. Neurologists, however, are under-supported and under-resourced for promoting exercise in comprehensive MS care. The purpose of this study was to determine the priorities of neurologists for exercise promotion among patients in comprehensive MS care and, where possible, provide suggestions for how each priority may be addressed in practice.

METHODS

Priority areas were identified through deductive content analysis of 20 semi-structured interviews with practicing neurologists.

RESULTS

Seven priority areas were identified regarding promotion of exercise among patients in comprehensive MS care. These included 1). How do I fit exercise promotion into a patient's appointment? 2). What resources should I give my patients about exercise? 3). What are the benefits of exercise for people with MS? 4). What training can I do to be better informed about exercise? 5). What are the prescriptions/guidelines for exercise among persons with MS? 6). What kind of services can I rely on to support me in promoting and supporting exercise behavior? 7). How do I negotiate reimbursement and insurance restrictions when I promote exercise?

CONCLUSIONS

This research sets an agenda regarding approaches for exercise promotion among patients with MS through interactions with neurologists in comprehensive care settings.

Experiences of venue based exercise interventions for people with stroke in the UK: a systematic review and thematic synthesis of qualitative research

BACKGROUND

The physical benefits of exercise following stroke are research evidenced and the UK stroke population is increasingly encouraged to engage with exercise interventions. A synthesis of qualitative research is required to further understand the perceived experience and psychosocial effect of exercise for people with stroke.

OBJECTIVES

To provide a systematic search and synthesis of evidence about the experiences and reported impact of participation in venue based exercise following stroke in the UK.

DATA SOURCES

Eligible studies were identified through a rigorous search of Medline, Cinahl, AMED, PsycINFO, SportDiscus, Proquest and ETHOS from January 2000 until December 2017.

STUDY ELIGIBILITY CRITERIA

Full text qualitative studies or service evaluations conducted in the UK which explored the reported experience of venue based exercise amongst people with stroke.

STUDY SYNTHESIS AND APPRAISAL

Included studies were evaluated through application of the Consolidated Criteria for Reporting Qualitative Research. Data synthesis using a thematic approach generated descriptive and analytical themes.

RESULTS

Six research studies and one service evaluation met the inclusion criteria; methodological quality was variable. These studies highlighted that people with stroke gain confidence and renewed identity through exercise participation. Perceived improvements in physical function were reported and participants enjoyed stroke specific exercise programmes in de-medicalised venues.

LIMITATIONS

The studies only accessed people who had completed the exercise programmes; non-completers were not represented.

CONCLUSION

Venue based exercise programmes have a positive effect on perceived wellbeing following stroke. Further research into the reasons for discontinuation of exercise participation following stroke is required. Systematic Review Registration Number PROSPERO 2017:CRD42017072483.
