Group-Based Individualized Comprehensive Core Stability Intervention Improves Balance in Persons With Multiple Sclerosis: A Randomized Controlled Trial

Views of Specialist Clinicians and People With Multiple Sclerosis on Upper Limb Impairment and the Potential Role of Virtual Reality in the Rehabilitation of the Upper Limb in Multiple Sclerosis: Focus Group Study

BACKGROUND

Finding enjoyable and effective long-term approaches to rehabilitation for improving the upper limb (UL) function of people with multiple sclerosis (MS) is challenging. Using virtual reality (VR) could be a solution to this challenge; however, there is a lack of reporting on the views of people with MS and clinicians on VR-based approaches and recommendations for games for rehabilitation.

OBJECTIVE

This study aims to identify common UL problems and their related current therapeutic approaches for people with MS, and to explore the opinions of people with MS and specialist clinicians on VR and obtain suggestions for the development and design of VR games.

METHODS

Separate focus groups were conducted with people with MS, recruited through the MS Society UK's research network, and clinicians, recruited through the MS Trust Therapists in MS network. A total of 10 people with MS (2 focus groups) and 8 clinicians (5 physiotherapists, 2 occupational therapists, and 1 MS nurse in 2 focus groups) were involved. The focus groups were recorded and transcriptions were analyzed using theme-based content analysis.

RESULTS

People with MS commonly reported that their UL problems interfered with activities of daily living and resulted in the loss of meaningful hobbies such as writing. Many people with MS neglected UL exercise and found strategies for adapting to the UL impairments. Similarly, clinicians stated UL rehabilitation was neglected within their service and that it was challenging to find interesting treatment strategies. VR was suggested by both participant groups as a solution, as it was convenient for people with MS to access and it could provide a more engaging and disguised approach to exercise. There were shared concerns with cybersickness and disengagement with using VR approaches. Both groups agreed games should be meaningful and adaptable for users but suggested different VR activities, with clinicians suggesting games directly reflecting activities of daily living and people with MS suggesting more abstract activities.

CONCLUSIONS

VR was well received by both people with MS and clinicians for UL rehabilitation. Recommendations were made for the development of VR rehabilitation games which are personalized and customizable for the varying abilities of people with MS.

Effect of a Home-Base Core Stability Exercises in Hereditary Ataxia. A Randomized Controlled Trial. A Pilot Randomized Controlled Trial

BACKGROUND

Core stability exercises (CSE) have been shown to be effective in improving trunk function in several neurological diseases, but the evidence is scarce on Hereditary Ataxias (HA).

OBJECTIVE

To evaluate the effectiveness of a 5-week home-based CSE program in terms of ataxia severity, trunk function, balance confidence, gait speed, lower limb motor function, quality of life, health status and falls rate in HA individuals at short- and long-term.

METHODS

This is an assessor-blind randomized controlled clinical trial parallel group 1:1. The individuals were divided in experimental group (EG) performed standard care in addition to CSE, and control group (CG) performed standard care alone. The CSE home-program was conducted 1-h/day, 5-day/week for 5-week. The assessment was performed at baseline, endpoint (5-week), and follow-up (10-week). The primary outcomes were ataxia severity assessed by the Scale for the Assessment and Rating of Ataxia and trunk function assessed by Spanish-version of Trunk Impairment Scale 2.0. The secondary outcomes were balance confidence assessed by Activities-specific Balance Confidence (ABC), gait speed by 4-meter walk test (4-MWT), the lower limb motor function by 30-s sit-to-stand, quality of life by EuroQol 5-dimension 5-level (EQ-5D-5L), health-status by EQ-5D and falls rate.

RESULTS

Twenty-three HA individuals were recruited (51.8 ± 11.10 years). Statistically significant group-time interaction was shown in ABC (F:5.539; P = 0.007), EQ-5D-5L Total (F:4.836; P = 0.013), EQ 5D (F:7.207; P = 0.006).

CONCLUSIONS

No statistical differences between groups for ataxia severity and trunk function were observed. However, were differences for balance confidence, gait speed, quality of life, and falls rate in HA individuals.

Use of pragmatic randomized trials in multiple sclerosis: A systematic overview

BACKGROUND

Pragmatic trials are increasingly recognized for providing real-world evidence on treatment choices.

OBJECTIVE

The objective of this study is to investigate the use and characteristics of pragmatic trials in multiple sclerosis (MS).

METHODS

Systematic literature search and analysis of pragmatic trials on any intervention published up to 2022. The assessment of pragmatism with PRECIS-2 (PRagmatic Explanatory Continuum Indicator Summary-2) is performed.

RESULTS

We identified 48 pragmatic trials published 1967-2022 that included a median of 82 participants (interquartile range (IQR) = 42-160) to assess typically supportive care interventions (n = 41; 85%). Only seven trials assessed drugs (15%). Only three trials (6%) included >500 participants. Trials were mostly from the United Kingdom (n = 18; 38%), Italy (n = 6; 13%), the United States and Denmark (each n = 5; 10%). Primary outcomes were diverse, for example, quality-of-life, physical functioning, or disease activity. Only 1 trial (2%) used routinely collected data for outcome ascertainment. No trial was very pragmatic in all design aspects, but 14 trials (29%) were widely pragmatic (i.e. PRECIS-2 score ⩾ 4/5 in all domains).

CONCLUSION

Only few and mostly small pragmatic trials exist in MS which rarely assess drugs. Despite the widely available routine data infrastructures, very few trials utilize them. There is an urgent need to leverage the potential of this pioneering study design to provide useful randomized real-world evidence.

The meaningfulness of exploring one's own limits through interactions and enjoyment in outdoor high-intensity physiotherapy for people with multiple sclerosis: a qualitative study

Background and purpose

Physical activity (PA) is often reduced in people with MS (pwMS), even when disability is low. Understanding the perspectives of pwMS on interventions aiming to improve PA is important to inform the development of such services. The aim of this study was to explore the experiences of pwMS participating in an outdoor, high-intensity and balance exercise group intervention.

Methods

This qualitative study was nested within an RCT exploring a novel intervention integrating sensorimotor exercises with high-intensity intervals of running/walking. Individual, in-depth interviews with the intervention group (n = 15; 12 women, 3 men; age 38-66; EDSS score 0-3.5) were conducted postintervention (mean days = 14), analyzed using a phenomenological-inspired approach with systematic text condensation, and interpreted based on enactive theory.

Results

Four categories were generated: (1) Exploration of one's own physical abilities: Challenging one's own limits was perceived by all participants to improve movement performance and/or intensity level. Such bodily changes engendered strong positive feelings. Some negative consequences of high-intensity training were described, increasing a feeling of loss. (2) New insights and beliefs: Participants experienced enhanced beliefs in their own capabilities, which they integrated in activities outside the intervention. (3) An engaging environment: The group setting was perceived as supportive, and the outdoor environment was perceived as stimulating activity. (4) Professional leadership, tailoring and co-creation of enjoyment: Physiotherapist-led, individualized interactions were regarded as necessary to safely revisit prior activities, such as running. Co-creating enjoyment facilitated high-intensity training and intervention adherence.

Discussion

High-intensity training combined with detailed exercises in a physiotherapy outdoor group was perceived to create meaningful bodily changes and enhance PA and prospects for both PA and life. Importantly, however, some negative experiences were also reported from the high-intensity training. Enactive theory allowed for the illumination of new perspectives: the importance of embodiment for self-efficacy and of tailored physiotherapy and an outdoor-group environment for exploring one's own limits to physical capabilities. These aspects should inform future exercise interventions in pwMS with low disability.

Feasibility of a new intervention addressing group-based balance and high-intensity training, physical activity, and employment in individuals with multiple sclerosis: a pilot randomized controlled trial

Background and purpose

Impaired sensorimotor function, reduced physical activity and unemployment are common challenges in persons with multiple sclerosis (pwMS), even when disability is low. CoreDISTparticipation is a new, multidisciplinary intervention delivered across healthcare levels systematically addressing these elements. This study primarily aimed to evaluate the feasibility of CoreDISTparticipation in terms of process, resources, management, and scientific outcomes. The secondary aim was to evaluate initial efficacy in terms of possible short-term effects compared with the usual care on barriers to employment, balance, walking, health-related quality of life (HRQoL), and physical activity.

Methods

This assessor-blinded prospective pilot randomized controlled trial included 29 pwMS [Expanded Disability Status Scale (EDSS): 0-3.5] randomly allocated to the intervention group (CoreDISTparticipation) (n = 15) or usual care (n = 14). CoreDISTparticipation consists of three phases: (1) hospital outpatient clinic: MS nurse work-focused session and physiotherapist exploring balance; (2) municipality: a digital meeting with pwMS, employer, MS nurse, and physiotherapist addressing employment and physical activity, 4 weeks indoor CoreDIST balance training (60 min × 2/week); and (3) 4 weeks outdoor CoreDIST balance training and high-intensity running/walking (60 min × 2/week). Assessments were undertaken at baseline and at weeks 6 and 11. Primary feasibility metric outcomes were the reporting of process, resources, management, and scientific outcomes. Efficacy measures included evaluation of the Multiple Sclerosis Work Difficulties Questionnaire-23 Norwegian Version (MSWDQ-23NV) and 6 Minute Walk-test as well as the Trunk Impairment Scale-modified Norwegian Version, Mini-Balance Evaluation Systems Test (Mini-BESTest), Multiple Sclerosis Walking Scale-12, Multiple Sclerosis Impact Scale-29 Norwegian Version (MSIS-29NV), ActiGraph wGT3x-BT monitors, and AccuGait Optimized force platform. The statistical analyses included repeated-measures mixed models performed in IBM SPSS Version 29.

Results

The primary feasibility metric outcomes demonstrated the need for minor adjustments in regard to the content of the intervention and increasing the number of staff. In regard to the efficacy measures, one person attended no postintervention assessments and was excluded, leaving 28 participants (mean EDSS: 1.8, SD: 1). The mean percentage employment was 46.3 (SD: 35.6) and 65.4 (SD: 39.3) in the CoreDISTparticipation and usual care group, respectively. No between-group differences were found. MSWDQ-23NV demonstrated a within-group difference of 5.7 points from baseline to Week 11 (P = 0.004; confidence interval: 2.2-9.3). Mini-BESTest and MSIS-29NV demonstrated within-group differences. The study is registered in ClinicalTrials.gov (Identifier: NCT05057338).

Discussion

The CoreDISTparticipation intervention is feasible to support pwMS when the identified feasibility metric outcomes in regard to process, resource, management, and scientific outcome metrics are adjusted to improve feasibility. Regarding efficacy measures, no between-group differences were detected; however, within-group differences in barriers to employment, balance, and HRQoL were detected for the CoreDISTparticipation group. A larger comparative trial is needed to explore between-group differences and should accurately and precisely define usual care and address the identified limitations of this study.

The effect of multi-function swing suspension training on upper and lower extremities function and quality of life in multiple sclerosis women with different disability status

BACKGROUND

Multiple sclerosis (MS) can lead to impaired upper and lower extremity function (ULEF), which reduces the quality of life (QoL). Exercise is beneficial for symptom management, but newer approaches like multi-function swing suspension training (MFSST) need further investigation. Additionally, tailoring exercises to individual needs remains a challenging area of investigation.

AIM

To investigate the effect of an MFSST program on ULEF, and QoL in MS women according to the expanded disability status scale (EDSS) score.

METHODS

Forty-seven MS women meeting selection criteria were randomly assigned to intervention groups A (EDSS 2-4) and B (EDSS 4.5-6.5), and the control group (EDSS 2-6.5). Intervention groups did an 8-week MFSST program with 3 × 1hr sessions/week. Prior to the intervention, and after 4, 6, and 8 weeks, the 9-hole peg test (9HPT) and the timed 25-foot walk (T25FW) test were performed for both the intervention groups and the control group. The Short Form questionnaire (SF-36) was used to measure their QoL.

RESULTS

Significant main effects for time were observed in both the 9HPT (F = 52.48, p = 0.001, Pη2 = 0.78) and the T25FW (F = 85.63, p = 0.000, Pη2 = 0.859). Speed increased between the pre-test, 4th week, 6th week, and 8th week in both tests. These tests revealed significant interaction effects between group and time. The 9HPT had an F-value of 9.01 (p = 0.001, Pη2 = 0.392), while the T25FW had an F-value of 13.812 (p = 0.000, Pη2 = 0.497). Across both tests, Group B, with higher EDSS scores, demonstrated greater speed improvement over the three-time measurements (4th week, 6th week, and 8th week) than Group A. The control group did not exhibit any improvement in speed. Intervention groups showed improvement in all QoL subscales except emotional role limitation.

CONCLUSIONS

An 8-week MFSST improves ULEF and QoL in women with MS, particularly those with higher EDSS scores (more than 4.5). Notably, significant improvements were observed after four weeks of the intervention. The incorporation of a variety of exercises in a single device provides a significant advantage over traditional exercise programs. Therefore, MFSST can be a valuable and efficient tool for improving symptoms and QoL in MS patients.

Physical Activity in Multiple Sclerosis: Meeting the Guidelines at the Time of the COVID-19 Pandemic

BACKGROUND AND PURPOSE

Regular physical activity (PA) helps to reduce the severity of physical and mental symptoms and improves quality of life in people with multiple sclerosis (PwMS). Based on current evidence and expert opinion, the recent multiple sclerosis guidelines recommend at least 150 minutes/week of PA. This study presents the results of a survey analyzing whether and how PwMS met the guidelines before and during the pandemic.

METHODS

We developed and disseminated an international online survey between December 2020 and July 2021, investigating changes in self-reported PA type, duration, frequency, and intensity due to the COVID-19 outbreak in PwMS with differing disability levels.

RESULTS

Among respondents (n = 3810), 3725 were eligible. The proportion of those who conducted at least one activity decreased with increasing disability level at both time points (pre and during). Overall 60% of respondents met the guidelines before the pandemic (mild: 64.43%; moderate: 51.53%; severe: 39.34%; χ 2(2) = 109.13, P < 0.01); a reduction of approximately 10% occurred during the pandemic in all disability groups (mild: 54.76%; moderate: 42.47%; severe: 29.48%; χ 2(2) = 109.67, P < 0.01). Respondents with higher disability participated more in physical therapy and less in walking, cycling, and running at both time points. Most respondents reported practicing PA at a moderate intensity at both time points; frequency and duration of sessions decreased as disability level increased.

DISCUSSION AND CONCLUSIONS

The percentage of those meeting the guidelines reduced with increasing disability level and during the pandemic. PA type and intensity varied widely across the disability categories. Interventions accounting for disability level are required to enable more PwMS to reap the benefits of PA.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A415 ).

Smartphone accelerometry for quantifying core stability and developing exercise training progressions in people with multiple sclerosis

BACKGROUND

Core stability exercise programs have become popular in recent years for preserving balance and functional independence in people with multiple sclerosis (PwMS); however, their real impact is not well-known as the main intervention target (i.e., core stability) theoretically responsible for balance or functional improvements is not measured. The objective of this study was to test the reliability of accelerometers integrated into smartphones for quantifying core stability and developing exercise progressions in PwMS.

METHODS

Twenty participants with MS [age: 47.5±8.0 years; height: 1.62±0.07 m; mass: 63.4±10.9 kg; EDSS: 3.0 (1.5-6)] participated voluntarily in this study. CS was assessed in different variations of the front, side, and back bridges and bird-dog exercises by measuring the mean lumbopelvic acceleration in two testing sessions, separated by one week. Relative and absolute reliability of lumbopelvic acceleration of those exercise variations performed by more than 60% of the participants was analyzed by the intraclass correlation coefficient (ICC_3,1), and the standard error of measurement (SEM) and the minimal detectable change (MDC), respectively. Repeated measures ANOVAs were performed to detect a potential learning effect between test-retest assessments. Statistical significance was set at p < 0.05.

RESULTS

Reliability analyses revealed that good to excellent relative and absolute scores (0.85<ICC<0.96; 7.8%≤SEM≤19.2%; 21.6%≤MDC≤53.2%) for the mean lumbopelvic acceleration obtained during 10 of the 12 CS exercise variations performed by more than 60% of the participants. A non-significant between-session learning effect was detected in all the variables considered (all p values >0.05).

CONCLUSION

Smartphone accelerometry seems a low cost, portable and easy-to-use tool to objectively and reliably track core stability changes in PwMS through. However, in spite of the popularity of bridging and bird-dog exercises, only the short and long bridges and the three-point bird-dog positions proved feasible for most participants. Overall, this study provides useful information to evaluate and guide the prescription of core stability exercise programs in PwMS with mild-to-moderate impairment.

Effect of Dynamic Neuromuscular Stabilization on Balance, Trunk Function, Falling, and Spasticity in People With Multiple Sclerosis: A Randomized Controlled Trial

OBJECTIVE

To compare the effects of core stabilization (CS) and dynamic neuromuscular stabilization (DNS) on balance, trunk function, mobility, falling, and spasticity, in people with multiple sclerosis (PWMS).

DESIGN

Two-group randomized controlled trial.

SETTING

General community and referral center.

PARTICIPANTS

A total of 64 PWMS, between 30 and 50 years old, and an expanded disability status scale between 2 and 5, participated in this study (N=64).

INTERVENTIONS

Participants were randomly assigned to CS (n=32) and DNS (n=32) groups. Both groups received a total of 15 sessions of CS or DNS exercises, 60 minutes per session, 3 times a week during the 5 weeks.

OUTCOME MEASURES

Balance function was measured as the primary outcome measure. Trunk function, postural stability, falling rate, fear of falling, falling index, mobility, and spasticity were measured as secondary outcomes.

RESULTS

DNS group had significant improvement in Berg balance scale, trunk impairment scale, postural stability, activities-specific balance confidence, reduced falling rate, the timed Up and Go (TUG), multiple sclerosis walking scale-12, and multiple sclerosis spasticity scale in PWMS compared with the CS group, (P<.0001) after 5 weeks of intervention and 17 weeks of follow-up. Except for the modified Ashworth scale (MAS), significant improvements were seen in all outcome measures in both groups after 5 weeks of intervention.

CONCLUSION

This is the first clinical evidence to support the importance of DNS exercise in improving balance, trunk function, and fall prevention in PWMS. This study provides clinical evidence that DNS may be more effective for PWMS than CS.

Mobility and balance rehabilitation in multiple sclerosis: A systematic review and dose-response meta-analysis

OBJECTIVE

To assess the benefits of neurological rehabilitation and the dose-response relationship for the treatment of mobility and balance in multiple sclerosis.

METHODS

We included studies investigating the effects of neurological rehabilitation on mobility and balance with the following eligibility criteria for inclusion: Population, People with Multiple Sclerosis (PwMS); Intervention, method of rehabilitation interventions; Comparison, experimental (specific balance intervention) vs control (no intervention/no specific balance intervention); Outcome, balance clinical scales; Study Design, randomised controlled trials. We conducted a random effects dose-response meta-analysis to assess linear trend estimations and a one stage linear mixed effects meta-regression for estimating dose-response curves.

RESULTS

We retrieved 196 studies from a list of 5020 for full text review and 71 studies (n subjects=3306) were included. One study was a cross-over and 70 studies were randomized controlled trials and the mean sample size per study was 46.5 ± 28.6 (mean±SD) with a mean age of 48.3 ± 7.8years, disease duration of 11.6 ± 6.1years, and EDSS of 4.4 ± 1.4points. Twenty-nine studies (40.8%) had the balance outcome as the primary outcome, while 42 studies (59.1%) had balance as secondary outcome or did not specify primary and secondary outcomes. Thirty-three trials (46.5%) had no active intervention as comparator and 38 trials (53.5%) had an active control group. Individual level data from 20 studies (n subjects=1016) were analyzed showing a medium pooled effect size for balance interventions (SMD=0.41; 95% CIs 0.22 to 0.59). Moreover, we analyzed 14 studies (n subjects=696) having balance as primary outcome and BBS as primary endpoint yielding a mean difference of 3.58 points (95% CIs 1.79 to 5.38, p<0.0001). Finally, we performed meta regression of the 20 studies showing an association between better outcome, log of intensity defined as minutes per session (β=1.26; SEβ=0.51; p = 0.02) and task-oriented intervention (β=0.38; SEβ=0.17; p = 0.05).

CONCLUSION

Our analyses provide level 1 evidence on the effect of balance intervention to improve mobility. Furthermore, according to principles of neurological rehabilitation, high intensity and task-specific interventions are associated with better treatment outcomes.

Improvement in the multiple sclerosis functional composite score by multi-function swing suspension training program

BACKGROUND

Physical activity has been considered as a promising approach to slow down the disease process in Multiple Sclerosis (MS) patients. The functional impairments of MS have been studied in detail, while evidence of the efficacy of exercise training interventions on the Multiple Sclerosis functional composite (MSFC) score in these patients is limited. The aim of this study was to investigate the improvement in MSFC score by multi-function swing suspension training program (MFSST) in the women with MS.

METHODS

The patients were divided into two groups as the intervention and control groups. A total of 47 MS patients completed the MSFC components at baseline and after the intervention: the timed 25-foot walk (T25FW); the 9-hole peg test (9HPT); and paced auditory serial addition test (PASAT). Z scores were created for each test based on control means.

RESULTS

The MSFC score, 9HPT, T25FW, and PASAT showed a significant increment in comparison with the baseline levels in the four, six, and eight weeks following the first exercise session (all p<0.05). These differences in the control group were not significant. The improvement in the MSFC score and the component Z-scores in the intervention groups was found from the fourth week onwards.

CONCLUSIONS

The study findings highlight that the progression of MS disability can be partially compensated by physical exercise. Overall, these results indicate that MFSST can be used as an effective treatment method in patients suffering from MS. Longer (years) exercise studies with larger samples of MS patients, with different MS subtypes, and of different sex, are needed to evaluate the effect of other types of exercise interventions on the MSFC score in MS patients with different disabilities.

Embodiment, tailoring, and trust are important for co-construction of meaning in physiotherapy after stroke: A qualitative study

Background and Purpose

Physiotherapy, with an emphasis on high intensity, individually tailored, and person‐centered treatment, is an effective route for recovery after a stroke. No single approach, however, has been deemed paramount, and there is limited knowledge about the patient experience of assessment, goal‐setting, and treatment in physiotherapy. In this study, we seek to report patient experiences of I‐CoreDIST—a new physiotherapy intervention that targets recovery—and those of usual care. The purpose is to investigate how individuals with stroke experience the bodily and interactive course of physiotherapy during their recovery process.

Methods

A qualitative study, nested within a randomized controlled trial, consisting of in‐depth interviews with 19 stroke survivors who received either I‐CoreDIST or usual care. Data were analyzed using systematic text condensation, and this analysis was informed by enactive theory.

Results

Interaction with the physiotherapist, which was guided by perceived bodily changes, fluctuated between being, on the one hand, formal/explicit and, on the other, tacit/implicit. The experiences of participants in the intervention group and the usual care group differed predominantly with regards to the content of therapy sessions and the means of measuring progress; divergences in levels of satisfaction with the treatment were less pronounced. The perception of positive bodily changes, as well as the tailoring of difficulty and intensity, were common and essential features in generating meaning and motivation. An embodied approach seemed to facilitate sense‐making in therapy situations. In the interaction between the participants and their physiotherapists, trust and engagement were important but also multifaceted, involving both interpersonal skills and professional expertise.

Conclusion

The embodied nature of physiotherapy practice is a source for sense‐making and meaning‐construction for patients after a stroke. Trust in the physiotherapist, along with emotional support, is considered essential. Experiencing progress and individualizing approaches are decisive motivators.

The content and effects of trunk rehabilitation on trunk and upper limb performance in people with multiple sclerosis: a systematic review

INTRODUCTION

Persons with multiple sclerosis (pwMS) could have an impaired trunk and reduced postural control, which negatively impacts activities of daily living. Evidence is growing to consider the positive effects of trunk training on fall incidence and balance problems. Effects on trunk and upper limb performance is unknown. This systematic review provides an overview of trunk training programs and their effects in MS, specifically focusing on the content of training modalities and the effects on trunk and upper limb performance.

EVIDENCE ACQUISITION

Two electronic databases were used: PubMed and Web Of Science (WOS). Intervention studies (with- and without control group) published in English, investigating the effects of active trunk training on trunk and upper limb performance in pwMS, were included.

EVIDENCE SYNTHESIS

Sixteen studies met the criteria, investigating different rehabilitation modalities. The included interventions in the review varied between more generic postural interventions such as Pilates (N.=8) and Ai Chi (N.=1), with a focus on abdominal muscle activation, breathing, neutral position and lower extremity movements. Further, specifically developed trunk training programs like GroupCoreDIST/ SIT / CoDuSe (N.=6) and Bobath based trunk training (N.=1) are detected, with the main focus on trunk strengthening and dynamic movements. An overall improvement in trunk performance was reported in several tests on trunk strength, stability and coordination. While the majority of the programs integrated the upper limb, only half of them used upper limb outcome measures to evaluate the effect. Here, overall significant improvements were found for the upper limb.

CONCLUSIONS

This systematic review showed that different types of trunk training programs can improve trunk and upper limb function in PwMS. The findings of this review suggest that a focus on trunk training to achieve effects on upper limb is reasonable. Future research is needed to further explore relations and the effect sizes.

What is the distribution of trunk impairments and its relationship with disability level in individuals with multiple sclerosis?

BACKGROUND

Trunk control is essential for movement, balance and walking and is ignored in the regular medical follow-up.

OBJECTIVE

First, to describe the distribution of trunk impairments in the full range of disability levels in individuals with MS. Second, to identify the relationship between trunk control, measured by the Trunk Impairment Scale (TIS 2.0.), and general disability measured by the Expanded Disability Status Scale (EDSS).

METHODS

154 individuals with MS were included (mean age 53.6; SD 11.06), EDSS ranging from 1.0- 8.5 (mean 4.47; SD 2.55). The relationship between EDSS and TIS 2.0. was calculated by Spearman correlation coefficient for the total sample and subgroups, EDSS ≤ 4 versus EDSS ≥ 4.5.

RESULTS

Trunk impairments were detected throughout the full range of disability, including individuals with low disability. Pelvic elevation and lower trunk rotation appeared most difficult to perform. In the total sample, a moderate correlation was found (rho= -0.608**) between disability (EDSS) and trunk performance (TIS 2.0.). Sub-analyses revealed a poor correlation (rho= -0.193) for the EDSS ≤ 4 subgroup and a strong correlation for the EDSS ≥ 4.5 subgroup (rho= -0.712**).

CONCLUSION

The results advocate for including trunk assessment already at early disease stages of MS, particularly of pelvic elevation and trunk rotation, and dedicated rehabilitation strategies.

Physical Activity and the Health of Wheelchair Users: A Systematic Review in Multiple Sclerosis, Cerebral Palsy, and Spinal Cord Injury

OBJECTIVE

To understand the benefits and harms of physical activity in people who may require a wheelchair with a focus on people with multiple sclerosis (MS), cerebral palsy (CP), and spinal cord injury (SCI).

DATA SOURCES

Searches were conducted in MEDLINE, Cumulative Index to Nursing and Allied Health, PsycINFO, Cochrane CENTRAL, and Embase (January 2008 through November 2020).

STUDY SELECTION

Randomized controlled trials, nonrandomized trials, and cohort studies of observed physical activity (at least 10 sessions on 10 days) in participants with MS, CP, and SCI.

DATA EXTRACTION

We conducted dual data abstraction, quality assessment, and strength of evidence. Measures of physical functioning are reported individually where sufficient data exist and grouped as "function" where data are scant.

DATA SYNTHESIS

No studies provided evidence for prevention of cardiovascular conditions, development of diabetes, or obesity. Among 168 included studies, 44% enrolled participants with MS (38% CP, 18% SCI). Studies in MS found walking ability may be improved with treadmill training and multimodal exercises; function may be improved with treadmill, balance exercises, and motion gaming; balance is likely improved with balance exercises and may be improved with aquatic exercises, robot-assisted gait training (RAGT), motion gaming, and multimodal exercises; activities of daily living (ADL), female sexual function, and spasticity may be improved with aquatic therapy; sleep may be improved with aerobic exercises and aerobic fitness with multimodal exercises. In CP, balance may be improved with hippotherapy and motion gaming; function may be improved with cycling, treadmill, and hippotherapy. In SCI, ADL may be improved with RAGT.

CONCLUSIONS

Depending on population and type of exercise, physical activity was associated with improvements in walking, function, balance, depression, sleep, ADL, spasticity, female sexual function, and aerobic capacity. Few harms of physical activity were reported in studies. Future studies are needed to address evidence gaps and to confirm findings.

Rehabilitation in multiple sclerosis in 2021

Patients with multiple sclerosis, despite advances in therapy, often suffer from locomotor impairment that limits their mobility and affect quality of life. Rehabilitation is part of the treatment of MS and has shown its beneficial effects in numerous studies. While traditional rehabilitation techniques remain in the limelight, new technologies are emerging and make it possible to improve the management of disabling symptoms. The aim of this update is to synthesize the new therapy techniques proposed in rehabilitation for patients with multiple sclerosis according to the symptoms as balance, gait, upper limb disorders, fatigue, spasticity and disease progression published over the past 5 years. With regard to balance and walking disorders, neuromotor rehabilitation, physical exercise, rhythmic auditory stimulation, gait robot training and exergaming are effective. Only physical exercise has shown a positive effect on fatigue management. Spasticity is improved by classic rehabilitation techniques however non-invasive brain stimulation are promising. The rehabilitation of upper limb dysfunctions uses various effective techniques such as the repetition of functional tasks in real or virtual situations. In case of a more severe disability, arm robots can be used to relearn the impaired movement. Action observation training in real or virtual situations is also effective. Finally, under certain conditions the constraint induced movement therapy is proposed. The effects of rehabilitation are not only positive on the pyramidal symptoms and fatigue but also increase neuroplasticity and perhaps a neuroprotective effect as shown in some studies.

Group dynamics in a group-based, individualized physiotherapy intervention for people with multiple sclerosis: A qualitative study

OBJECTIVE

Group-based physiotherapy is a common and beneficial intervention for people with multiple sclerosis (MS). Most group interventions are not individually adapted to each participant's needs. Evidence on how individualization and group elements can be combined in a clinical setting is lacking. The objective of this study is to expand the knowledge base in neurological physiotherapy by investigating the nature of group dynamics in a group-based, individualized intervention for people with MS.

METHODS

This qualitative study included 13 nonparticipatory video observations (14 hr 38 min) of GroupCoreDIST exercise sessions complemented by 13 interviews (12 hr 37 min) with physiotherapists (PTs). The purposively sampled participants included 40 patients with MS (expanded disability scale of 1.0-6.5) and six PTs with expertise in neurological physiotherapy. Data were analysed using systematic text condensation in an enactive theoretical framework.

RESULTS

Two main categories emerged from the material. (a) Individual systems affect group dynamics: Individual perceptions of success through adapted and embodied approaches positively affected the dynamics of the group. (b) Disease and exercise peer support: Social support was a substantial product of dynamic group processes and was enhanced through the PTs' strategic focus on experience sharing.

CONCLUSION

The results revealed that group dynamics benefit from individualization and the PTs' focus on experience sharing. These findings are contrary to the prevailing view that individualization and group-based interventions are mutually exclusive and thus should be considered in group-based interventions for people with MS.

Group-based, individualized exercises can provide perceived bodily changes and strengthen aspects of self in individuals with MS: a qualitative interview study

Background: Group-based physiotherapy is effective for individuals with MS; nevertheless individualization within groups is questioned and little is known regarding individuals´ experiences with individualization in small groups.Objective: We aimed to explore the short- and long-term experiences of individuals with MS participating in a 6-week, group-based, individualized physiotherapy-intervention.Methods: Within a randomized controlled trial (RCT), 25 in-depth interviews with a strategic sample of 13 people (9 women; age 25-79 years old; European Disability Status Scale (EDSS) 1-6.5) were conducted at weeks 7 and 30 using systematic text condensation, with dynamic systems theory and phenomenology as analytical frameworks.Results: The main categories were: 1) movement control, orientation and insights: Bodily improvements were associated with targeted exercises, specific adjustments by the physiotherapist, emotional engagement and re-access to activities; and 2) the individual within the group: Equal distributions of one-to-one interactions and attention were important for experiencing success. Less attention and improvements turned attention toward own disability. Physical changes felt particularly emotional short term, implying that individuals' feelings of ownership and control of body and movement, new views of themselves and changed affordances in daily life were involved.Conclusion: Equally distributed attention and engagement, targeted exercises and hands-on adjustments resulting in visible and perceived bodily changes were experienced as key factors of individualization in small groups.
