Two Different Types of High-Frequency Physical Therapy Promote Improvements in the Balance and Mobility of Persons With Multiple Sclerosis

Immediate effects of wearing textured versus smooth insoles on standing balance and spatiotemporal gait patterns when walking over even and uneven surfaces in people with multiple sclerosis

PURPOSE

To investigate the immediate effects of wearing novel sensory-stimulating textured insoles on balance and gait in 41 people with multiple sclerosis (pwMS).

MATERIALS AND METHODS

Assessments of balance (firm/foam surface; eyes open/closed) and walking (when negotiating even/uneven surfaces) were performed wearing textured insoles, smooth insoles, shoes only, and barefoot. Outcome measures were centre of pressure (CoP) movement during standing (elliptical area, sway path velocity) and spatiotemporal gait patterns (stride/step width, stride time, double-limb support time, stride length, velocity).

RESULTS

Wearing textured insoles led to reductions in CoP velocity measures when standing on foam with eyes open and closed when compared to barefoot (p values ≤0.02). Textured insoles did not appear to be consistently superior to smooth insoles or shoes only for improving gait. Relative to the insole/shoe conditions, walking barefoot led to poorer gait performance for the even and uneven surface tasks (p values ≤0.03).

CONCLUSIONS

For pwMS, stimulating the foot with "texture" appears to provide enhanced sensory input with the capacity to improve CoP movement control during standing; offering a potential new treatment option for balance rehabilitation. Further research is needed to identify which individuals may benefit most from textured insoles.Implications for rehabilitationTextured shoe insoles, designed to stimulate plantar mechanoreceptors, are a novel approach to improve standing balance and walking patterns in people with multiple sclerosis (pwMS).Wearing textured insoles for the first time can lead to improvements in centre of pressure movement control when standing on an unstable compliant supporting surface.Textured insoles offer a potential new treatment technique for balance rehabilitation in pwMS who show early signs of diminished foot sensation.

Effects of wearing textured versus smooth shoe insoles for 12 weeks on gait, foot sensation and patient-reported outcomes, in people with multiple sclerosis: a randomised controlled trial

BACKGROUND

Innovative shoe insoles, designed to enhance sensory information on the plantar surface of the feet, could help to improve walking in people with Multiple Sclerosis.

OBJECTIVE

To compare the effects of wearing textured versus smooth insoles, on measures of gait, foot sensation and patient-reported outcomes, in people with Multiple Sclerosis.

METHODS

A prospective, randomised controlled trial was conducted with concealed allocation, assessor blinding and intention-to-treat analysis. Thirty ambulant men and women with multiple sclerosis (MS) (Disease Steps rating 1-4) were randomly allocated to wear textured or smooth insoles for 12 weeks. Self-reported insole wear and falls diaries were completed over the intervention period. Laboratory assessments of spatiotemporal gait patterns, foot sensation and proprioception, and patient-reported outcomes, were performed at Weeks 0 (Baseline 1), 4 (Baseline 2) and 16 (Post-Intervention). The primary outcome was the size of the mediolateral base of support (stride/step width) when walking over even and uneven surfaces. Independent t-tests were performed on change from baseline (average of baseline measures) to post-intervention.

RESULTS

There were no differences in stride width between groups, when walking over the even or uneven surfaces (P ≥ 0.20) at post-intervention. There were no between-group differences for any secondary outcomes including gait (all P values > 0.23), foot sensory function (all P values ≥ 0.08) and patient-reported outcomes (all P values ≥ 0.23).

CONCLUSIONS

In our small trial, prolonged wear of textured insoles did not appear to alter walking or foot sensation in people with MS who have limited foot sensory loss. Further investigation is needed to explore optimal insole design.

Unwrapping the "black box" of balance training in people with multiple sclerosis - A descriptive systematic review of intervention components, progression, and intensity

BACKGROUND

Delineating the specific components of the existing balance training interventions in people with multiple sclerosis (PwMS) may contribute to a framework for future design and reporting of such interventions. Thus, we aimed to systematically synthesize how balance training frequency, intensity, time, type, duration, and progression are reported in balance training interventions for PwMS.

METHODS

A systematic literature search was conducted in Medline, Embase, Web of Science, and Cinahl. Search terms were MS, postural balance, walking, gait, and randomized/quasi-randomized controlled or clinical trials. Articles including ambulatory PwMS and interventions designed to challenge the balance control system were eligible. Two investigators screened, selected, and extracted data independently. Data on study characteristics such as design, population, and balance training content were extracted. Categorization of balance training based on balance control components was performed.

RESULTS

We included 40 studies grouped under five balance training categories. Balance interventions were well described regarding frequency, session time, and duration, but only two interventions described training intensity, and no systematic, gradual progression approach was reported for balance training adaptation over time. However, the balance training interventions included many sensory and motor components of the balance control system. Still, little focus was on reactive motor strategies, vestibular sense, and cognitive dual-tasking.

CONCLUSIONS

Existing balance training interventions in PwMS primarily consist of practicing sensory and motor strategies. Future balance training interventions are encouraged to systematically monitor individual advancements in balance training adaptations and to apply the progressive overload principle (i.e. continuous increase in balance exercise stimulus over time). Furthermore, we suggest that balance training in PwMS is performed with high intensity near an individual's balance capacity limits. Finally, individualized balance training is recommended to cover all relevant components of balance control using the proposed framework.

Outcome measures used in trials on gait rehabilitation in multiple sclerosis: A systematic literature review

Background

Multiple Sclerosis (MS) is associated with impaired gait and a growing number of clinical trials have investigated efficacy of various interventions. Choice of outcome measures is crucial in determining efficiency of interventions. However, it remains unclear whether there is consensus on which outcome measures to use in gait intervention studies in MS.

Objective

We aimed to identify the commonly selected outcome measures in randomized controlled trials (RCTs) on gait rehabilitation interventions in people with MS. Additional aims were to identify which of the domains of the International Classification of Functioning, Disability and Health (ICF) are the most studied and to characterize how outcome measures are combined and adapted to MS severity.

Methods

Pubmed, Cochrane Central, Embase and Scopus databases were searched for RCT studies on gait interventions in people living with MS according to PRISMA guidelines.

Results

In 46 RCTs, we identified 69 different outcome measures. The most used outcome measures were 6-minute walking test and the Timed Up and Go test, used in 37% of the analyzed studies. They were followed by gait spatiotemporal parameters (35%) most often used to inform on gait speed, cadence, and step length. Fatigue was measured in 39% of studies. Participation was assessed in 50% of studies, albeit with a wide variety of scales. Only 39% of studies included measures covering all ICF levels, and Participation measures were rarely combined with gait spatiotemporal parameters (only two studies).

Conclusions

Selection of outcome measures remains heterogenous in RCTs on gait rehabilitation interventions in MS. However, there is a growing consensus on the need for quantitative gait spatiotemporal parameter measures combined with clinical assessments of gait, balance, and mobility in RCTs on gait interventions in MS. Future RCTs should incorporate measures of fatigue and measures from Participation domain of ICF to provide comprehensive evaluation of trial efficacy across all levels of functioning.

Acceptability and outcomes of an individualized exergaming telePT program for veterans with multiple sclerosis: a pilot study

Background

Physical rehabilitation services are an important component of treatment for persons with multiple sclerosis (PwMS) to improve and maintain physical mobility. However, PwMS often have significant barriers to outpatient physical therapy (PT) services including mobility deficits and lack of transportation. The integration of exercise gaming (exergaming) and telehealth into clinical PT practices may overcome these barriers. The overarching purpose of this pilot study was to evaluate the acceptability and effects of an individualized telePT intervention using exergaming.

Methods

Ten individuals with multiple sclerosis (MS) completed a 12-week exergaming (Jintronix®) telerehabilitation intervention. In order to measure the acceptability of the telerehabilitation intervention, adherence was measured through the tablet-based rehabilitation software and each participant completed a satisfaction questionnaire. Clinical outcome measures were assessed at baseline and post-intervention. To evaluate the efficacy of this intervention, the following measures of physical function and fatigue were included; the Short Physical Performance Battery (SPPB), 25-Foot Walk (25FW), Modified Fatigue Impact Scale (MFIS), Multiple Sclerosis Walking Scale-12 (MSWS), and the 2-Minute Walk Test (2MWT). Clinical outcomes were analyzed using the Sign test and Wilcoxon signed rank test. All other data were evaluated using descriptive statistics.

Results

After the intervention, participants demonstrated significant improvements in ambulation speed during the 25FW (p = 0.04) and ambulation distance during the 2MWT (p = 0.002). Statistically significant increases of SPPB total score (p = .04) and sub-scores were also found. Participants did not demonstrate significant changes in the MFIS (p = 0.31) or MSWS-12 (p = 0.06) after the intervention. Participants had a 58.3% adherence rate during the intervention and performed their exercise program an average of 2.5 times per week. All participants reported that they were either ‘satisfied or ‘very satisfied’ with their telerehabilitation experience, would use telerehabilitation again, and would recommend telerehabilitation to others.

Conclusion

This individualized telerehabilitation intervention which integrates exergaming and clinical video teleconferencing is acceptable to patients and may offer a viable alternative to traditional PT for PwMS.

The effect of stem cell therapy and comprehensive physical therapy in motor and non-motor symptoms in patients with multiple sclerosis: A comparative study

INTRODUCTION

People with multiple sclerosis (PwMS) experience a wide range of disabilities which negatively impact their quality of life (QOL). Several interventions have been used in PwMS such as medication, physical therapy exercises and stem cell therapy to improve their QOL. However, there is a limited evidence on the benefits of combining interventions. The purpose of this study is to explore the effect of combining physical therapy exercises (PTE) and Wharton Jelly mesenchymal stem cell (WJ-MSCs) injections on motor and non-motor symptoms versus each intervention alone in PwMS.

METHODS

Sixty PwMS will be allocated to either PTE, WJ-MSCs, or a combined group, followed up for 12 months and examined using a comprehensive battery of measures. Participants in the PTE group will receive 2 sessions per week of a supervised exercise program for 6 months followed by a home exercise program for another 6 months. The WJ-MSCs group will receive 3 WJ-MSCs injections in the first 6 months then they will be encouraged to follow an active life style. The third group will receive both interventions.

DISCUSSION

This study will aid in a better understanding of the combined effect of physical therapy and mesenchymal stem cell therapy. The results from this proposed study may reduce disability, improve QOL in PwMS, and consequently, reduce the cost associated with the life-time care of these individuals worldwide.

Center-Based Group and Home-Based Individual Exercise Programs Have Similar Impacts on Gait and Balance in People With Multiple Sclerosis: A Randomized Trial

BACKGROUND

Group and home-based exercises to improve function in people with multiple sclerosis (MS) are common but have little underpinning evidence.

OBJECTIVE

To determine the comparative effectiveness of a center-based group versus home-based individual 8-week exercise program to improve gait and balance in people with MS.

DESIGN

Prospective, randomized controlled trial.

SETTING

Community center-based and home-based exercise program.

PARTICIPANTS

Fifty people with MS were randomized and completed allocated intervention (n = 26 center, n = 24 home), 47 completed post-assessment and 44 follow-up assessment.

METHODS

The center- and home-based groups completed an 8-week progressive functional and balance training exercise program. The center-based groups of four to six were supervised by a physiotherapist. The home-based group was provided with telephone support.

MAIN OUTCOME MEASUREMENTS

The primary outcome was gait speed (10-meter walk test). Secondary outcomes were gait endurance (6-minute walk test) and balance (Berg Balance Scale). Outcome assessments were conducted at baseline, immediately postintervention and at 8-week follow-up.

RESULTS

There was no statistically significant difference between groups in gait speed post training, with a mean difference of 0.01 m/s, 95% CI -0.36 to 0.37. There were no group effects, time effects, or interactions for gait speed, endurance, or balance. In both groups, gait speed improved to a level that met minimal clinically important differences.

CONCLUSIONS

Gait speed, endurance, and balance did not statistically improve in either group; however, gait speed changes met minimally important differences.

Effects of downslope walking on Soleus H-reflexes and walking function in individuals with multiple sclerosis: A preliminary study

BACKGROUND

Downslope walking (DSW) is an eccentric-based exercise intervention that promotes neuroplasticity of spinal reflex circuitry by inducing depression of Soleus Hoffman (H)-reflexes in young, neurologically unimpaired adults.

OBJECTIVE

The objective of the study was to evaluate the effects of DSW on spinal excitability (SE) and walking function (WF) in people with multiple sclerosis (PwMS).

METHODS

Our study comprised two experiments on 12 PwMS (11 women; 45.3±11.8 years). Experiment 1 evaluated acute effects of a single 20-minute session of treadmill walking at three different walking grades on SE, 0% or level walking (LW), - 7.5% DSW, and - 15% DSW. Experiment 2 evaluated the effects of 6 sessions of DSW, at - 7.5% DSW (with second session being - 15% DSW) on SE and WF.

RESULTS

Experiment 1 showed significantly greater acute % H-reflex depression following - 15% DSW compared to LW (p = 0.02) and - 7.5% DSW (p = 0.05). Experiment 2 demonstrated significant improvements in WF. PwMS who showed greater acute H-reflex depression during the - 15% DSW session also demonstrated greater physical activity, long-distance WF, and the ability to have greater H-reflex depression after DSW training. Significant changes were not observed in regards to SE.

CONCLUSIONS

Though significant changes were not observed in SE after DSW training, we observed an improvement in WF which merits further investigation of DSW in PwMS.

Is there an overlooked “window of opportunity” in MS exercise therapy? Perspectives for early MS rehabilitation

While early medical treatment has proven effective in MS, early-phase MS rehabilitation has not gained much attention in MS research and clinical practice. Exercise therapy is one of the most promising treatment strategies in MS rehabilitation. Here, we provide a topical review investigating when exercise therapy is initiated in existing MS studies, showing that exercise is initiated at a rather late disease stage, where it predominantly serves as a symptomatic treatment. Recent findings in MS suggest that exercise may have neuroprotective and disease-modifying effects. Such findings along with the findings from medical trials that an early-stage “window of opportunity” exists leads to the proposal that early exercise therapy should be an increased focus in research and clinical practice for persons with MS. A further perspective relates to other rehabilitation interventions that are also initiated at a later disease stage, as these may also take advantage of an early-phase approach.

Efficacy of Balance and Eye-Movement Exercises for Persons With Multiple Sclerosis (BEEMS)

Objective

To determine whether a multifaceted vestibular-related rehabilitation program (Balance and Eye-Movement Exercises for Persons with Multiple Sclerosis; BEEMS) improves balance in persons with MS and whether there are differences in outcomes based on brainstem/cerebellar lesion involvement.

Methods

A 2-arm, examiner-blinded, stratified (involvement vs no involvement of brainstem/cerebellar structures), randomized controlled trial was implemented. Eighty-eight participants were allocated to BEEMS or no treatment control. Computerized Dynamic Posturography-Sensory Organization Test (CDP-SOT) measured balance control. The Dizziness Handicap Inventory (DHI), Modified Fatigue Impact Scale (MFIS), and Short Form-36 Health Status Questionnaire (SF-36) were also administered. Linear mixed models were used to investigate the primary and secondary aims.

Results

From baseline to 6 weeks, BEEMS participants experienced greater improvements compared to control participants in CDP-SOT composite (model-estimated difference in change 4.9, 95% confidence interval 1.39–8.38, p = 0.006), DHI total (−13.5, −17.7 to −7.25, p < 0.0001), MFIS total (−11.4, −15.7 to −7.0, p < 0.0001), SF-36 Mental (5.6, 2.43–8.71, p = 0.0006), and SF-36 Physical (3.5, 1.12–5.81, p = 0.004) scores and from baseline to 14 weeks in CDP-SOT composite (8.3, 4.73–11.9, p < 0.0001), DHI total (−13.9, −19.3 to −8.62, p < 0.0001), MFIS total (−12.3, −16.7 to −7.79, p < 0.0001), SF-36 Mental (3.9, 0.70–7.16, p = 0.02), and SF-36 Physical (3.2, 0.79–5.62, p = 0.01) scores. From baseline to 6 weeks, BEEMS participants with brainstem/cerebellar lesion involvement experienced greater improvements compared to those without in CDP-SOT composite (5.26, 0.34–10.2, p = 0.04) and MFIS total (−7.6, −14.0 to −1.33, p = 0.02) scores.

Conclusion

BEEMS improved multiple outcomes regardless of whether brainstem/cerebellar lesions were present, supporting the generalizability of BEEMS for ambulatory people with MS who have at least minimally impaired balance and fatigue.

Classification of evidence

This study provides Class I evidence that BEEMS training improves dynamic posturography-based balance, dizziness, fatigue, and quality of life in persons with MS.

Effects of Sport Climbing on Multiple Sclerosis

Multiple sclerosis (MS) is an autoimmune and neurodegenerative disease of the central nervous system (CNS) with different types of disease courses (relapsing-remitting, secondary-progressive, primary progressive) that leads to physical as well as mental disability. The symptoms comprise paresis or/and paralysis, ataxia, bladder dysfunction, visual problems as well as effects on cognition. There is limited data regarding the possible effects of sport climbing respectively therapeutic climbing on patients with MS. Sport climbing offers many potentially beneficial effects for patients with MS since there are effects on coordination, muscular strength, and cognition to name the most relevant ones. Also, disease models in rodents point toward such positive outcomes of climbing. Therefore, we assessed the currently available research literature on general effects of physical exercise, impact of climbing on body and mind and therapeutic climbing for prevention or therapy for the treatment of MS. The sparse published controlled trials that investigated this sport activity on different groups of patients with neurological or geriatric diseases grossly differ in study design and outcome parameters. Nevertheless, it appears that climbing offers the opportunity to improve some of the symptoms of patients with MS and can contribute to an enhanced quality of life.
