Effects of vestibular rehabilitation on multiple sclerosis-related fatigue and upright postural control: a randomized controlled trial

Abnormal Vestibulo-Ocular Reflex Function Correlates with Balance and Gait Impairment in People with Multiple Sclerosis

BACKGROUND

Multiple Sclerosis (MS) is the most prevalent autoimmune neurological condition in the world, leading to a wide variety of symptoms, including balance disorders.

OBJECTIVE

To evaluate the angular vestibulo-ocular reflex (aVOR) of all six semicircular canals (SCCs) through Head Impulse (HIMP) and Suppression HIMP (SHIMP) paradigms and any correlations with clinical balance scales.

METHODS

All participants were assessed using the Expanded Disability Status Scale (EDSS), Berg Balance Scale (BBS), and Mini-BESTest (MBT). Vestibular function was measured by video Head Impulse Test (vHIT), obtaining aVOR gain for each SSC.

RESULTS

Twenty-seven PwMS (mean age 47.93 ± 8.51 years old, 18 females) were recruited. Most of the patients (81.48%) presented abnormal aVOR gains for at least one SSC. A moderate to strong correlation between aVOR gains of the left anterior SSC and, respectively, the MBT and the BBS was found. The subgroup analysis, based on the EDSS class, confirmed the correlation with the BBS in the patients with the most significant disability.

CONCLUSIONS

People with MS may present impairments of the aVOR in one or more semicircular canals. The aVOR gain impairment of the vertical semicircular canals correlates with balance and gait disorders identified through clinical scales in PwMS.

Best practice exercise for emerging depression in multiple sclerosis: A systematic review and meta-analysis

OBJECTIVE

To examine the effects of instructor-led exercise on depression symptoms in adults with multiple sclerosis, with a focus on moderating factors to treatment response.

DATA SOURCES

Cochrane Library, Embase, PEDro, PsycINFO and PubMed databases were searched until 21 April 2024.

REVIEW METHODS

The reporting quality of included studies assessed (PEDro and TESTEX scales). Hedges' g effect sizes were calculated and pooled using random and mixed-effects modelling.

RESULTS

Twenty-two independent studies (k), representing 785 participants with relapsing remitting or progressive MS, were included. Individual studies varied in their reporting quality (PEDro range: 3-8) and did not routinely detail exercise parameters (TESTEX range: 5-13). Nonetheless, exercise reduced core symptoms of depression (gw = .52, CI: .30-.73, P < .01). Treatment effects were, however, not maintained once training had ceased (gw = -.53, CI: -.80 to .24, P ≤ .01, k = 5). Both aerobic and non-aerobic exercise groups experienced a significant (P < .01) reduction in depression scores. Larger gains were noted by those with better ambulation at baseline (P = .03).

CONCLUSION

Regular exercise can help to stabilise mood for people living with multiple sclerosis, regardless of session frequency or duration. Treatment efficacy could be maximised by addressing potential barriers for those with limited mobility, including exercise type, delivery and intensity.

Wearable sensor and smartphone assisted vestibular physical therapy for multiple sclerosis: usability and outcomes

Introduction

Vertigo, dizziness, gaze instability and disequilibrium are highly prevalent in people with MS (PwMS) and head movement induced dizziness is commonly reported. Vestibular physical therapy (VPT) is a specialised, non-invasive and effective therapy for these problems but usually involves travel for the person to a specialist center with both personal and carbon costs. The use of wearable sensors to track head movement and smartphone applications to deliver and track programs has potential to improve VPT in MS.

Methods

This study investigated the usability and effects of a commercially available digital VPT system (wearable head sensor, smartphone app and clinician software) to deliver VPT to PwMS. A pre/post treatment design was employed and the primary outcome was the System Usability Scale (SUS). Other patient reported outcomes were the Service User Acceptability Questionnaire (SUTAQ), the Patient Enablement Instrument (PEI) and the Dizziness Handicap Inventory (DHI). Physical outcomes measurements included Mini-BESTest (MB), Modified Dynamic Gait Index (mDGI), Gait Speed (GS), Dynamic Visual Acuity (DVA) and head kinematics and symptoms during exercise.

Results

Sixteen PwMS (14 female), mean age 44(±14) years were recruited to the study and twelve completed VPT. Mean adherence to exercise, measured digitally was 60% (±18.4). SUS scores were high at 81 (±14) and SUTAQ scores also demonstrated high levels of satisfaction and acceptability of the system. Statistically significant improvements in MB (mean change 2.25; p = 0.004), mDGI (median change 1.00; p = 0.008), DVA (median change -1.00; p = 0.004) were found. Head frequencies significantly improved with concurrent decreased intensity of dizziness during head movements (mean change across 4 gaze stabilization exercises was 23 beats per minute; p < 0.05). Non-significant improvements were seen in DHI (p = 0.07) and GS (p = 0.15). 64.5% of follow up visits were conducted remotely (video or phone), facilitated by the system.

Discussion

This study had two main outcomes and benefits for PwMS. Firstly, we showed that the system used was both acceptable and could be used by PwMS. Secondly, we demonstrated an improvement in a range of dizziness, balance and gait metrics with remotely delivered care. This system has the potential to positively impact on MS physiotherapy service provision with the potential to deliver effective remote care.

S. J. Effectiveness of vestibular rehabilitation therapy and yoga in the management of chronic peripheral vertigo: A randomized controlled trial

Background

The purpose of the study was to compare the effectiveness of yoga as a form of Vestibular Rehabilitation (VR) to standard VR for managing patients with symptoms such as dizziness, disequilibrium and gait instability.

Methods

150 participants based on 18-point difference in the DHI score were randomly assigned to group 1- Yoga, group 2- VR and group 3- control group using block randomization. The intervention was provided for 12 weeks. The participants were assessed for Dizziness Handicap Inventory (DHI) at baseline, 4 th, 8 th and 12 th week.

Results

The mean DHI for group 1(41.12±7.13) group 2 (42.96±10.54) group 3 (50.84±10.78), p<0.001 decreased significantly in group 1 and 2 when compared to baseline. There was no statistically significant difference in overall Dizziness Handicap Inventory (DHI) scores between the Yoga and Physiotherapy groups after one month; however, both groups resulted in a significant decrease in scores when compared to the control group. Similarly, by the end of the second and third months, there was no significant distinction between the Yoga and Physiotherapy groups, even though both had a considerable decrease in DHI scores when compared to the control group. Furthermore, an examination of the functional, emotional, and physical components of DHI demonstrated persistent trends of significant improvement in both the Yoga and Physiotherapy groups as compared to the control group over a three-month period.

Conclusions

In addition to VR, Yoga and medications administered concurrently can provide effective therapeutic effects. Yoga has an advantage over VR since it offers a customized cure for giddiness in addition to symptom relief. Yoga might be a great alternative to the conventional VR because along with enhancing overall body relaxation, it is affordable and is easy to learn.

The effect of exercise on mental health and health-related quality of life in individuals with multiple sclerosis: A Systematic review and meta-analysis

BACKGROUND

A large body of evidence has tested the effect of exercise interventions on mental health and health-related quality of life (HRQoL) in individuals with multiple sclerosis (PwMS).

OBJECTIVE

To determine the effect of exercise interventions on mental health and HRQoL in PwMS.

METHODS

We searched four databases up to April 2023, and included randomized controlled trials that: 1) involved PwMS ≥18 years old; 2) delivered an exercise intervention; 3) measured subjective well-being, psychological well-being, social well-being, or HRQoL as outcomes. We reported standardized differences in means (d) with a 95 % confidence interval (CI), for continuous outcomes and an incidence rate ratio (IRR) with a 95 % CI for dichotomous outcomes.

RESULTS

Forty-nine studies (n = 2,057 participants) were included. Exercise improved overall well-being (d = 0.78; 95 % CI 0.483, 1.077; moderate certainty evidence), subjective well-being (d = 0.666; 95 % CI 0.405, 0.928; moderate certainty evidence), social well-being (d = 1.046; 95 % CI 0.569, 1.523; low certainty evidence), and HRQoL (d = 0.568; 95 % CI 0.396, 0.74; moderate certainty evidence).

CONCLUSION

Exercise interventions can improve well-being and HRQoL in PwMS. Future studies should focus on PwMS ≥ 65 years or with higher level of impairments.

Influence of transcutaneous electrical nerve stimulation on the distance walked by older adults during the 6-min test of walking endurance

The purpose of our study was to compare the influence of two types of transcutaneous electrical nerve stimulation (TENS) on the performance of older adults on the 6-min test of walking endurance and on the ability to maintain balance during upright standing. Twenty-six healthy older adults (72 ± 5.4 yrs) performed tests of motor function while TENS was applied to the tibialis anterior and rectus femoris muscles of each leg. Linear mixed models were used to compare the influence of TENS on walking distance in a 6-min test of walking endurance and on sway-area rate in tests of standing balance. There was a significant decrease in the distances walked in each minute of the 6-min walk test for both the Continuous and Burst TENS modes compared with Baseline (p < 0.01 and p < 0.001, respectively). The influence of TENS on walking distance was associated with several significant effects on the mean and coefficient of variation for stride length and stride frequency between the first and last minute of the test and between the two TENS modes and the Baseline values. In contrast, there was no significant effect of TENS on sway-area rate in any balance test, which indicates that the supplementary sensory feedback compromised walking performance of older adults but not the ability to maintain balance during upright standing.

Overview of the Current Pathophysiology of Fatigue in Multiple Sclerosis, Its Diagnosis and Treatment Options - Review Article

Fatigue is a common, debilitating and often underestimated symptom in patients with multiple sclerosis (MS). The exact pathophysiological mechanism of fatigue in MS is still unknown. However, there are many theories involving different immunological, metabolic and inflammatory mechanisms of fatigue. Owing to the subjective nature of this symptom, its diagnosis is still very limited and is still based only on diagnostic questionnaires. Although several therapeutic agents have been used in the past to try to influence fatigue in MS patients, no single effective approach for the treatment of fatigue has yet been found. This review article aims to provide the reader with information on the current theories on the origin and mechanism of fatigue in MS, as well as diagnostic procedures and, finally, current therapeutic strategies for the management of fatigue in MS patients.

Effect of different types of exercise on fitness in people with multiple sclerosis: A network meta-analysis

BACKGROUND

It is assumed that people with multiple sclerosis (MS) who participate in programs of physical exercise improve their physical fitness.

OBJECTIVE

The aim of this network meta-analysis (NMA) was to analyze the effect of different types of exercise on muscular fitness and cardiorespiratory fitness (CRF) among people with MS and to determine the best type of exercise according to disease severity.

METHODS

MEDLINE, the Physiotherapy Evidence Database, the Cochrane Library, SPORTDiscus, Scopus, and Web of Science were searched from inception to April 2022 to identify randomized controlled trials (RCTs) concerning the effect of physical exercise on fitness in people with MS. We ranked the types of physical exercise by calculating the surface under the cumulative ranking (SUCRA).

RESULTS

We included 72 RCTs involving 2543 MS patients in this NMA. A ranking of five types of physical exercise (aerobic, resistance, combined [aerobic and resistance], sensorimotor training, and mind-body exercises) was achieved. Combined and resistance training had the highest effect sizes (0.94, 95% CI 0.47, 1.41, and 0.93, 95% CI 0.57, 1.29, respectively) and the highest SUCRA (86.2% and 87.0%, respectively) for muscular fitness. The highest effect size (0.66, 95% CI 0.34, 0.99) and SUCRA (86.9%) for CRF was for aerobic exercise.

CONCLUSIONS

Combined and resistance training seem to be the most effective exercises to improve muscular fitness and aerobic exercise for CRF in people with MS.

Vestibular rehabilitation therapy on balance and gait in patients after stroke: a systematic review and meta-analysis

BACKGROUND

There is limited evidence to support the use of vestibular rehabilitation therapy (VRT) on improving balance and gait in patients after stroke. This systematic review aimed to evaluate the effects of VRT in addition to usual rehabilitation compared with usual rehabilitation on improving balance and gait for patients after stroke.

METHODS

This review followed the Preferred Reporting Items for Systematic reviews and Meta-Analysis statement guidelines. Ten electronic databases were searched up to 1 June 2023 without restrictions in language and publication status. The PEDro scale and the Grading of Recommendations Assessment Development, and Evaluation were used to evaluate the risk of bias and the certainty of evidence. The meta-analysis was conducted with Review Manager 5.3.

RESULTS

Fifteen randomised controlled trials with 769 participants were included. PEDro scale was used to assess the risk of bias with a mean score of 5.9 (0.7). VRT was effective in improving balance for patients after stroke (SMD = 0.59, 95% CI (0.40, 0.78), p < 0.00001), particularly for patients after stroke that occurred within 6 months (SMD = 0.56, 95% CI (0.33, 0.79), p < 0.00001) with moderate certainty of evidence. Subgroup analysis showed that VRT provided as gaze stability exercises combined with swivel chair training (SMD = 0.85, 95% CI (0.48, 1.22), p < 0.00001) and head movements (SMD = 0.75, 95% CI (0.43, 1.07), p < 0.00001) could significantly improve balance. Four-week VRT had better effect on balance improvement (SMD = 0.64, 95% CI (0.40, 0.89), p < 0.00001) than the less than 4-week VRT. The pooled mean difference of values of Timed Up-and-Go test showed that VRT could significantly improve gait function for patients after stroke (MD =  -4.32, 95% CI (-6.65, -1.99), p = 0.0003), particularly for patients after stroke that occurred within 6 months (MD =  -3.92, 95% CI (-6.83, -1.00), p = 0.008) with moderate certainty of evidence.

CONCLUSIONS

There is moderate certainty of evidence supporting the positive effect of VRT in improving balance and gait of patients after stroke.

A systematic review and meta-analysis of the effects of non-pharmacological interventions on quality of life in adults with multiple sclerosis

BACKGROUND

Multiple Sclerosis (MS) is a chronic debilitating disease that targets the central nervous system. Globally it is estimated that 2.8 million people live with MS (2018) and as there is no known cure; therefore, identifying methods to increase a patient's quality of life (QoL) is of considerable importance. Non-pharmacological interventions are a viable and effective option to increase QoL in patients with MS, however, to date, the literature lacks a complete systematic review of these interventions.

METHODS

A literature search was conducted for studies published up until March 4th 2022 in Scopus, Web of Science, CINAHL Plus, The Cochrane Library, Medline, and Embase. Studies were included if they were randomized control trials (RCTs) assessing a non-pharmacological intervention in adults with MS and measured QoL using the MSQOL-54, SF-36 or MSQLI tools for at least two time points. Quality assessment of each study was completed as well as a review of publication bias. Where possible, meta-analysis was conducted using a random effects model and for other studies a qualitative synthesis was presented.

RESULTS

Thirty studies were included in the meta-analysis and eleven studies were summarized qualitatively. The pooled effects across all non-pharmacological interventions showed a modest improvement in both the physical and mental components of QoL, with a standardized mean difference (SMD) of 0.44 (95% CI 0.26-0.61) and 0.42 (95% CI 0.24-0.60), respectively. Non-pharmacological interventions based around a physical activity were found to be particularly effective in improving both the physical composite score (PCS) and mental composite score (MCS), with an SMD of 0.40 (95% CI 0.14-0.66) and 0.31 (95% CI 0.08-0.55), respectively. Interventions incorporating balance exercises presented a significant advantageous solution for improving QoL, with an SMD of 1.71 (95% CI 1.22, 2.20) and 1.63(95% CI 1.15-2.12) for PCS and MCS respectively.

CONCLUSIONS

This systematic review and meta-analysis identified that non-pharmacological interventions can be an effective method of improving QoL in patients with MS, especially modalities with a physical activity component and balance interventions.

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.

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.

Participant characteristics of existing exercise studies in persons with multiple sclerosis - A systematic review identifying literature gaps

BACKGROUND

Exercise is a cornerstone in rehabilitation of persons with multiple sclerosis (pwMS), which is known to elicit beneficial effects on various symptoms and to have a potential disease-modifying effect. However, it remains to be elucidated if the existing MS exercise literature covers the full age and disability span of pwMS.

OBJECTIVE

To systematically review MS exercise studies and provide a detailed mapping of the demographic and clinical characteristics of the included pwMS.

METHODS

A systematic review of MS exercise studies were performed using MEDLINE and EMBASE. From the resulting MS exercise studies, mean sample characteristics were extracted.

RESULTS

4576 records were identified, from which 202 studies were included. Of these, 166 studies (82.2%) enrolled pwMS aged 35-54 years, 10.9% enrolled pwMS <35 years, and 6.9% enrolled pwMS ≥55 years (only 1.5% enrolled pwMS ≥60 years). A total of 118 studies (58.4%) reported Expanded Disability Status Scale (EDSS), with 88.1% of included pwMS having an EDSS between 2.0 and 6.5, while only one study enrolled pwMS with an EDSS ≥7.0. Finally, 80% of the studies included pwMS having a disease duration of 5-14.5 years.

CONCLUSION

Exercise studies in pwMS included primarily middle-aged (35-54 years) pwMS having an EDSS of 2.0-6.5 and a disease duration of 5-14.5 years. Few exercise studies were identified in young and older pwMS, in pwMS with mild disability and severe disability, and in pwMS having shorter or longer disease durations. These findings highlight the need for further investigation of exercise in these specific subgroups of pwMS as benefits of exercise might not generalize across subpopulations.

Multimodal Agility-Based Exercise Training for Persons With Multiple Sclerosis: A New Framework

INTRODUCTION

Multimodal agility-based exercise training (MAT) has been described as a framework for fall prevention in the elderly but might also be a valuable concept for exercise training in persons with Multiple Sclerosis (pwMS).

THE PROBLEM

Current recommendations advise pwMS to perform a multitude of different exercise training activities, as each of these has its separate evidence. However, pwMS struggle even more than the general population to be physically active. Additionally, Multiple Sclerosis often leads to co-occurring mobility and cognitive dysfunctions, for which simultaneous, time-efficient, and engaging training approaches are still limited in clinical practice and healthcare.

THE SOLUTION

The MAT framework has been developed to integratively improve cardiovascular, neuromuscular, and cognitive function by combining aspects of perception and orientation, change of direction, as well as stop-and-go patterns (ie, agility), in a group-training format. For pwMS, the MAT framework is conceptualized to include 3 Components: standing balance, dynamic balance (including functional leg strength), and agility-based exercises. Within these Components sensory, cognitive, and cardiovascular challenges can be adapted to individual needs.

RECOMMENDATIONS

We recommend investigating multimodal exercise interventions that go beyond easily standardized, unimodal types of exercise (eg, aerobic or resistance exercise), which could allow for time-efficient training, targeting multiple frequent symptoms of persons with mild disability at once. MAT should be compared to unimodal approaches, regarding sensor-based gait outcomes, fatigue-related outcomes, cognition, as well as neuroprotective, and (supportive) disease-modifying effects.

High-intensity resistance training in people with multiple sclerosis experiencing fatigue: A randomised controlled trial

BACKGROUND

Exercise studies including only fatigued persons with multiple sclerosis (PwMS) with fatigue as primary endpoint are lacking.

OBJECTIVE

To evaluate the effects of high-intensity resistance training (HIRT) on self-reported fatigue in fatigued PwMS in a single center randomised controlled trial.

METHODS

We recruited 71 PwMS scoring ≥ 53 on the Fatigue Scale for Motor and Cognitive Functions (FSMC), who were randomised 1:1 to either twice (group A) or once (group B) weekly supervised HIRT for twelve weeks. A non-randomised FSMC score-matched group (n=69) served as non-intervention control.

RESULTS

Between HIRT-group differences were non-significant for primary and most secondary endpoints. Mean difference in FSMC score (95% confidence intervals) was -10.9 (-14.8; -6.9) in group A and -9.8 (-13.2; -6.3) in group B. Corresponding values for combined HIRT groups vs non-intervention control were -10.3 (-12.9; -7.7) and 1.5 (-0.6;3.6), respectively, p<0.001. Secondary endpoints also improved in both HIRT groups, though only Hospital Anxiety and Depression Scale anxiety and MS Impact Scale-29 psychological subscales significantly favoured the twice a week HIRT (group A). As an exploratory endpoint, changes in plasma inflammatory protein markers were associated with reduced FSMC scores in the pooled material.

CONCLUSION

The finding that HIRT in fatigued PwMS leads to clinically relevant reductions in self-reported fatigue, associated with changes in plasma inflammatory protein levels, provide evidence for recommending HIRT for fatigued PwMS.

The Role of Ketogenic Diet in the Treatment of Neurological Diseases

Over a hundred years of study on the favourable effect of ketogenic diets in the treatment of epilepsy have contributed to a long-lasting discussion on its potential influence on other neurological diseases. A significant increase in the number of scientific studies in that field has been currently observed. The aim of this paper is a widespread, thorough analysis of the available scientific evidence in respect of the role of the ketogenic diet in the therapy of neurological diseases such as: epilepsy, Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS) and migraine. A wide range of the mechanisms of action of the ketogenic diet has been demonstrated in neurological diseases, including, among other effects, its influence on the reduction in inflammatory conditions and the amount of reactive oxygen species (ROS), the restoration of the myelin sheath of the neurons, the formation and regeneration of mitochondria, neuronal metabolism, the provision of an alternative source of energy for neurons (ketone bodies), the reduction in glucose and insulin concentrations, the reduction in amyloid plaques, the induction of autophagy, the alleviation of microglia activation, the reduction in excessive neuronal activation, the modulation of intestinal microbiota, the expression of genes, dopamine production and the increase in glutamine conversion into GABA. The studies discussed (including randomised controlled studies), conducted in neurological patients, have stressed the effectiveness of the ketogenic diet in the treatment of epilepsy and have demonstrated its promising therapeutic potential in Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS) and migraine. A frequent advantage of the diet was demonstrated over non-ketogenic diets (in the control groups) in the therapy of neurological diseases, with simultaneous safety and feasibility when conducting the nutritional model.

Greater Disability Is Associated with Worse Vestibular and Compensatory Oculomotor Functions in People Living with Multiple Sclerosis

Globally, there are nearly three million people living with multiple sclerosis (PLW-MS). Many PLW-MS experience vertigo and have signs of vestibular dysfunction, e.g., low vestibulo-ocular reflex (VOR) gains or the presence of compensatory saccades (CSs), on video head impulse testing (vHIT). We examined whether the vestibular function and compensatory oculomotor behaviors in PLW-MS differed based on the level of MS-related disability. The VOR gain, CS frequency and latency, and gaze position error (GPE) were calculated from the individual traces obtained during six-canal vHIT for 37 PLW-MS (mean age 53.4 ± 12.4 years-old, 28 females) with vertigo and/or an imbalance. The subjects were grouped by their Expanded Disability Status Scale (EDSS) scores: PLW-min-MS (EDSS = 1.0-2.5, n = 8), PLW-mild-MS (EDSS = 3.0-4.5, n = 23), and PLW-moderate-MS (EDSS = 5.0-6.0, n = 6). The between-group differences were assessed with Kruskal-Wallis tests. The VOR gains for most of the canals were higher for PLW-min-MS compared to PLW-mild- and mod-MS, respectively. CS occurred less often in PLW-min-MS versus PLW-mild- and mod-MS, respectively. No clear trend in CS latency was found. The GPE was often lower for PLW-min-MS compared to PLW-mild- and mod-MS, respectively. Thus, our data demonstrate that worse VOR and compensatory oculomotor functions are associated with a greater MS-related disability. PLW-MS may benefit from personalized vestibular physical therapy.

Rehabilitation to Improve Gaze and Postural Stability in People With Multiple Sclerosis: A Randomized Clinical Trial

BACKGROUND

People with multiple sclerosis (PwMS) frequently experience dizziness and imbalance that may be caused by central vestibular system dysfunction. Vestibular rehabilitation may offer an approach for improving dysfunction in these people.

OBJECTIVE

To test the efficacy of a gaze and postural stability (GPS) retraining intervention compared to a strength and endurance (SAE) intervention in PwMS.

METHODS

About 41 PwMS, with complaints of dizziness or history of falls, were randomized to either the GPS or SAE groups. Following randomization participants completed 6-weeks of 3×/week progressive training, delivered one-on-one by a provider. Following intervention, testing was performed at the primary (6-weeks) and secondary time point (10-weeks). A restricted maximum likelihood estimation mixed effects model was used to examine changes in the primary outcome of the Dizziness Handicap Inventory (DHI) between the 2 groups at the primary and secondary time point. Similar models were used to explore secondary outcomes between groups at both timepoints.

RESULTS

Thirty-five people completed the study (17 GPS; 18 SAE). The change in the DHI at the primary time point was not statistically different between the GPS and SAE groups (mean difference = 2.33 [95% CI -9.18, 12.85]). However, both groups demonstrated significant improvement from baseline to 6-weeks (GPS -8.73; SAE -7.31). Similar results were observed for secondary outcomes and at the secondary timepoint.

CONCLUSIONS

In this sample of PwMS with complaints of dizziness or imbalance, 6-weeks of GPS training did not result in significantly greater improvements in dizziness handicap or balance compared to 6-weeks of SAE training.

Randomised controlled pilot and feasibility study of multimodal agility-based exercise training (MAT) versus strength and endurance training (SET) to improve multiple sclerosis-related fatigue and fatigability during inpatient rehabilitation (ReFEx): study protocol

INTRODUCTION

Subjective fatigue and objectively assessed fatigability are common symptoms in persons with multiple sclerosis (pwMS). Recent work has suggested a positive effect of balance and motor control training (BMCT) in reducing fatigue. It is unclear whether this effect can also be attained during inpatient rehabilitation. Multimodal agility-based exercise training (MAT) has been developed as a framework that incorporates BMCT with added agility components but has not been applied to pwMS. Therefore, this study will evaluate the feasibility of a randomised controlled trial comparing MAT against strength and endurance training (SET) for the improvement of MS-related fatigue and fatigability in a German neurological rehabilitation centre.

METHODS AND ANALYSIS

A total of 24 pwMS (Expanded Disability Status Scale ≤5.0, Fatigue Scale for Motor and Cognitive Functions ≥53) will be randomly assigned to either SET or land and water-based MAT for 4-6 weeks during inpatient rehabilitation. Assessments of subjective fatigue, motor and cognitive fatigability, cognitive and cardiorespiratory performance, and balance confidence will be performed at admission and discharge. Subjective fatigue will also be assessed at 1, 4 and 12 weeks after discharge. Feasibility outcomes will include patients' acceptance of study procedures and interventions, recruitment rate, retention rate, time needed to complete baseline assessments, intervention adherence and fidelity.

The Effects of Vestibular Rehabilitation on Poststroke Fatigue: A Randomized Controlled Trial Study

Background

A major complication caused by stroke is poststroke fatigue (PSF), and by causing limitations in doing activities of daily living (ADL), it can lower the quality of life.

Objective

The present study is an attempt to examine the effects of vestibular rehabilitation on BADL (Basic Activities of Daily Living), fatigue, depression, and Lawton Instrumental Activities of Daily Living (IADL) in patients with stroke.

Method

Patients with a history of stroke took part voluntarily in a single-blind clinical trial. The participants were allocated to control and experimental groups randomly. The experimental group attended 24 sessions of vestibular rehabilitation protocol, while the control group received the standard rehabilitation (including three sessions per week each for around 60 min). To measure fatigue, the Fatigue Impact Scale (FIS) and the Fatigue Assessment Scale (FAS) were used. Depression, BADL, and IADL were measured using the Beck Depression Inventory-II (BDI-II), Barthel Index (BI), and Lawton Instrumental Activities of Daily Living, respectively. All changes were measured from the baseline after the intervention.

Results

Significant improvement was found in the experimental group compared to the control group (p < 0.05) in FIS (physical, cognition, and social subscales), FAS, BDI-II, BADL, and IADL. Moreover, the results showed small to medium and large effect sizes for the physical subscale of FIS and FAS scores based on Cohen's d, respectively; however, no significant difference was found in terms of cognition and social subscales of FIS, BDI-II, BADL, and IADL scores.

Conclusion

It is possible to improve fatigue, depression, and independence in BADL and IADL using vestibular rehabilitation. Thus, it is an effective intervention in case of stroke, which is also well tolerated.

Central vestibular dysfunction: don't forget vestibular rehabilitation

INTRODUCTION

Vestibular rehabilitation (VR) is now a subject of active studies and has been shown to be effective for multiple vestibular disorders, peripheral or central. VR is a physical therapy that helps train the central nervous system to compensate for vestibular dysfunction. There is moderate to strong evidence that VR is safe and effective for the management of peripheral vestibular dysfunction. Nonetheless, the studies on how VR works on central vestibular dysfunction remains scanty.

AREAS COVERED

This article addressed the rehabilitation strategies and possible mechanisms, including how central vestibular function might improve upon rehabilitation. In addition, it provides some examples concerning the effect of VR on central vestibular dysfunction.

EXPERT OPINION

VR works on the vestibular system through repetition of specific physical exercises that activate central neuroplastic mechanisms to achieve adaptive compensation of the impaired functions. VR has become a mainstay in the management of patients with dizziness and balance dysfunction. Individualized VR programs are a safe and effective treatment option for a large percentage of patients with central vestibular disease reporting imbalance and dizziness. Exploration of various treatment strategies and possible mechanisms will help develop the best and personalized VR treatment for patients with central vestibular dysfunction.

The effects of Baduanjin and yoga exercise programs on physical and mental health in patients with Multiple Sclerosis: A randomized controlled trial

OBJECTIVE

To discuss whether Baduanjin and yoga exercise interventions improve motor function, posture control, and relieving fatigue and depression in MS patients. And to explore whether practicing Baduanjin benefits MS patients more than yoga.

DESIGN

A prospective, randomized, controlled, three-arm trial comparing BDJ (n = 30), yoga (n = 30) and control group (n = 20).

SETTING

Jiangsu Provincial Corps Hospital.

INTERVENTION

Eligible participants were randomized to a 24-week Baduanjin or yoga intervention, or a usual activity control group. Balance, posture control and trunk movement were measured with the Berg Balance Scale (BBS) and Trunk Impairment Scale (TIS). Fatigue was measured using the Fatigue Severity Scale (FSS) and depressive symptoms via the Zung Self-Rating Depression Scale (SDS).

RESULTS

For BBS and TIS, there were significant changes pre- to post- exercise in two exercise groups (P < 0.05), with greater increases in the Baduanjin exercise group (BDJ group). For the FSS, there were significant changes pre- to post- exercise in both the BDJ (P = 0.0292) and yoga groups (P = 0.0150). For the SDS, the pre- and post-exercise difference of the BDJ group was larger than the yoga group (P < 0.0001). On the other hand, we could not find any changes of the BBS, TIS, FSS, and SDS scores in the control group (p > 0.05).

CONCLUSION

The results suggest that practicing Baduanjin was more effective than yoga and that it is suitable for the MS patients.

Perception, knowledge, and attitude of medical doctors in Saudi Arabia about the role of physiotherapists in vestibular rehabilitation: a cross-sectional survey

Objectives

There is compelling scientific evidence about the role of physiotherapists in vestibular rehabilitation. However, patients with vestibular-associated dizziness and balance disturbances are seldom referred to physiotherapists in Saudi Arabia. Therefore, this study aims to achieve insight into perceptions, knowledge, attitudes, and referral practices among Saudi Arabian medical doctors relating to the role of physiotherapists in vestibular rehabilitation.

Methods

A sample of 381 medical doctors practicing in Saudi Arabia participated in this nationwide cross-sectional study. The sample was obtained from 226 hospitals across 13 provinces of Saudi Arabia by stratified sampling method. The 23-item questionnaire developed by a team of experts was emailed to medical doctors practicing in various hospitals across Saudi Arabia.

Results

Out of 1,231 medical doctors invited, 381 medical doctors responded, giving a response rate of 30.9%. One hundred ninety-three (50.6%) medical doctors reported managing patients with vestibular rehabilitation. The most preferred specialist for managing patients with vestibular disorders was an Ear Nose Throat (ENT) specialist (n = 173, 89.6%). Related Sample Cochran's Q test showed statistically significant difference between preferred specialist for managing patients with vestibular disorders (ENT specialists, physiotherapists, nurses, occupational therapists and audiologists) (χ2(4) = 482.476, p = 0.001). Out of 193 medical doctors, 153 (79.2%) reported no role of the physiotherapist in vestibular rehabilitation. One hundred forty-five (75.1%) of medical doctors reported that they were not aware of the role of physiotherapists in vestibular rehabilitation. Only 27 (15.5%) medical doctors reported referring patients with vestibular disorders to physiotherapists.

Conclusion

The study reports that physiotherapy services are underutilized in vestibular rehabilitation due to limited referral from Saudi Arabian medical doctors. Therefore, there is a need to increase the awareness among Saudi Arabian doctors about the physiotherapist's role in vestibular rehabilitation.

Evaluating Oculomotor Tests before and after Vestibular Rehabilitation in Patients with Parkinson’s Disease: A Pilot Pre-Post Study

Introduction. The elderly population is commonly affected by balance and gait disorders that increase the risk of falls. Pivotal systems for efficient postural control are sensory, motor, visual, vestibular, and cognitive. Disruption in any of these systems could lead to postural instability. Vestibular rehabilitation is a set of exercises that positively affect the primary components of the central sensory-motor integration, including somatosensory, visual, and vestibular systems. Accordingly, we hypothesized that vestibular rehabilitation exercises might improve both oculomotor functions and upright postural control in patients with Parkinson’s disease. Materials and Methods. 11 idiopathic Parkinson’s patients voluntarily participated in this study based on inclusion criteria: central vestibular dysfunction and the Hoehn and Yahr scale scores less than or equal to 3. Videonystagmography (VNG) and the Berg Balance Scale (BBS) scores were measured at the baseline. Then, the patients underwent vestibular rehabilitation training for 24 sessions (3 sessions per week). The VNG and BBS were measured again after 48 hours of the completion of the last session of the training. Result. After completing vestibular rehabilitation sessions, there were significant improvements in balance $\left(P\le 0.001\right)$ . Eye-tracking and gaze function statistically improved in 7 patients and 6 patients, respectively. Conclusion. Vestibular rehabilitation produced positive effects on oculomotor function and balance in a small cohort of people with PD. Consequently, it could be considered as a possible effective intervention for Parkinson’s patients. This trial is registered with IRCT201709123551N6.

Walking With Horizontal Head Turns Is Impaired in Persons With Early-Stage Multiple Sclerosis Showing Normal Locomotion

Background

Turning the head while walking (an action often required during daily living) is particularly challenging to maintain balance. It can therefore potentially reveal subtle impairments in early-stage people with multiple sclerosis who still show normal locomotion (NW-PwMS). This would help in identifying those subjects who can benefit from early preventive exercise aimed at slowing the MS-related functional decline.

Objectives

To analyze if the assessment of walking with horizontal head turns (WHHT) through inertial sensors can discriminate between healthy subjects (HS) and NW-PwMS and between NW-PwMS subgroups. To assess if the discriminant ability of the instrumented WHHT is higher compared to clinical scores. To assess the concurrent validity of the sensor-based metrics.

Methods

In this multicenter study, 40 HS and 59 NW-PwMS [Expanded Disability Status Scale (EDSS) ≤ 2.5, disease duration ≤ 5 years] were tested. Participants executed Item-6 of the Fullerton Advanced Balance scale-short (FAB-s) wearing three inertial sensors on the trunk and ankles. The item required to horizontally turn the head at a beat of the metronome (100 bpm) while walking. Signals of the sensors were processed to compute spatiotemporal, regularity, symmetry, dynamic stability, and trunk sway metrics descriptive of WHHT.

Results

Mediolateral regularity, anteroposterior symmetry, and mediolateral stability were reduced in NW-PwMS vs. HS (p ≤ 0.001), and showed moderate discriminant ability (area under the receiver operator characteristic curve [AUC]: 0.71–0.73). AP symmetry and ML stability were reduced (p ≤ 0.026) in EDSS: 2–2.5 vs. EDSS: 0–1.5 subgroup (AUC: 0.69–0.70). The number of NW-PwMS showing at least one abnormal instrumented metric (68%) was larger (p ≤ 0.002) than the number of participants showing abnormal FAB-s-Item6 (32%) and FAB-s clinical scores (39%). EDSS: 2–2.5 subgroup included more individuals showing abnormal instrumented metrics (86%) compared to EDSS: 0–1.5 subgroup (57%). The instrumented metrics significantly correlated with FAB-s-Item6 and FAB-s scores (|Spearman's r_s| ≥ 0.37, p < 0.001), thus demonstrating their concurrent validity.

Conclusion

The instrumented assessment of WHHT provided valid objective metrics that discriminated, with higher sensitivity than clinical scores, between HS and NW-PwMS and between EDSS subgroups. The method is a promising tool to complement clinical evaluation, and reveal subclinical impairments in persons who can benefit from early preventive rehabilitative interventions.

Effects of Sensory Interventions on Fatigue in People With Multiple Sclerosis: A Systematic Review

BACKGROUND

Fatigue is 1 of the most common and annoying symptoms in patients with multiple sclerosis (MS). The purpose of this study was to investigate the effect of sensory interventions on fatigue in people with MS based on a systematic review of sensory evidence.

METHODS

The Google Scholar, PubMed, Scopus, and Cochrane Library databases were searched from January 1990 to July 2020. Studies with nonpharmacologic sensory interventions as a main or secondary intervention according to the assessment of fatigue as the primary or secondary therapy outcome in patients with MS were included.

RESULTS

Nine articles were reviewed by examining the inclusion and exclusion criteria. Four types of interventions were related to exercises, including sensory integration exercises, vestibular rehabilitation, Frenkel exercises, and exercises with or without vibration; and 2 types were performed using robots and 1 type using vibration only. Vestibular rehabilitation therapies, exercise-based sensory integration interventions, and the use of vibration have shown significant effects in relieving fatigue in patients with MS.

CONCLUSIONS

The evidence in this study is insufficient to show a dramatic effect of sensory integration therapy in various forms. However, despite the studies, sensory integration therapy can be considered a potential treatment for fatigue in patients with MS. Further studies with stronger methods are needed to make this treatment a reality.

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.

Feasibility and safety of an immersive virtual reality-based vestibular rehabilitation programme in people with multiple sclerosis experiencing vestibular impairment: a protocol for a pilot randomised controlled trial

INTRODUCTION

Vestibular system damage in patients with multiple sclerosis (MS) may have a central and/or peripheral origin. Subsequent vestibular impairments may contribute to dizziness, balance disorders and fatigue in this population. Vestibular rehabilitation targeting vestibular impairments may improve these symptoms. Furthermore, as a successful tool in neurological rehabilitation, immersive virtual reality (VRi) could also be implemented within a vestibular rehabilitation intervention.

METHODS AND ANALYSIS

This protocol describes a parallel-arm, pilot randomised controlled trial, with blinded assessments, in 30 patients with MS with vestibular impairment (Dizziness Handicap Inventory ≥16). The experimental group will receive a VRi vestibular rehabilitation intervention based on the conventional Cawthorne-Cooksey protocol; the control group will perform the conventional protocol. The duration of the intervention in both groups will be 7 weeks (20 sessions, 3 sessions/week). The primary outcomes are the feasibility and safety of the vestibular VRi intervention in patients with MS. Secondary outcome measures are dizziness symptoms, balance performance, fatigue and quality of life. Quantitative assessment will be carried out at baseline (T0), immediately after intervention (T1), and after a follow-up period of 3 and 6 months (T2 and T3). Additionally, in order to further examine the feasibility of the intervention, a qualitative assessment will be performed at T1.

ETHICS AND DISSEMINATION

The study was approved by the Andalusian Review Board and Ethics Committee, Virgen Macarena-Virgen del Rocio Hospitals (ID 2148-N-19, 25 March 2020). Informed consent will be collected from participants who wish to participate in the research. The results of this research will be disseminated by publication in peer-reviewed scientific journals.

Cognitive and Central Vestibular Functions Correlate in People With Multiple Sclerosis

Background. Cognitive impairment is common, but poorly managed in people with multiple sclerosis (MS). Balance has been correlated with cognition in people with MS, potentially through shared utilization of central sensory integration pathways. Objective. This study characterized the relationship between central vestibular integration and cognition in people with MS through measurement of several clinical vestibular functions requiring central sensory integration and multiple cognitive domains. Methods. Forty people with MS and 20 controls completed a battery of vestibular and cognitive examinations targeting different central vestibular integration measures and different domains of cognition, respectively. Performance on these measures was compared between people with MS and controls, and then correlational analyses were undertaken between the vestibular and cognitive measures in the MS sample. Results. People with MS performed worse than controls on all vestibular and cognitive measures. There were consistent correlations between vestibular and cognitive measures in the MS sample. Factor analysis of vestibular functions yielded a single factor hypothesized to represent central vestibular integration that demonstrated a significant relationship with a composite cognitive measure in people with MS. Discussion. Our results suggest that vestibular and cognitive dysfunction may both arise from central sensory processing pathways in people with MS. This connection could be targeted through vestibular rehabilitation techniques that improve central sensory processing and both balance and cognition in people with MS.

Cerebellar Contributions to Motor Impairments in People with Multiple Sclerosis

Although Charcot characterized classic cerebellar symptoms in people with multiple sclerosis (PwMS) in 1877, the impact of cerebellar dysfunction on MS symptoms has predominately been evaluated in the last two decades. Recent studies have clearly demonstrated the association between cerebellar pathology, including atrophy and reduced fractional anisotropy in the peduncles, and motor impairments, such as reduced gait velocity and time to complete walking tasks. However, future studies using novel imaging techniques are needed to elucidate all potential pathophysiology that is associated with disability in PwMS. Additionally, future studies are required to determine the most effective treatments for motor impairments in PwMS, including the specific type and duration of exercise interventions, and potential means to amplify their effects, such as transcranial direct current stimulation (tDCS). This mini-review critically discusses the distinct role of cerebellar dysfunction in motor impairments in PwMS, potential treatments, and directions for future studies.

Which exercise and behavioural interventions show most promise for treating fatigue in multiple sclerosis? A network meta-analysis

BACKGROUND

Fatigue is a common, debilitating symptom of multiple sclerosis (MS) without a current standardised treatment.

OBJECTIVE

The aim of this systematic review with network meta-analyses was to estimate the relative effectiveness of both fatigue-targeted and non-targeted exercise, behavioural and combined (behavioural and exercise) interventions.

METHODS

Nine electronic databases up to August 2018 were searched, and 113 trials (n = 6909) were included: 34 were fatigue-targeted and 79 non-fatigue-targeted trials. Intervention characteristics were extracted using the Template for Intervention Description and Replication guidelines. Certainty of evidence was assessed using GRADE.

RESULTS

Pairwise meta-analyses showed that exercise interventions demonstrated moderate to large effects across subtypes regardless of treatment target, with the largest effect for balance exercise (SMD = 0.84). Cognitive behavioural therapies (CBTs) showed moderate to large effects (SMD = 0.60), with fatigue-targeted treatments showing larger effects than those targeting distress. Network meta-analysis showed that balance exercise performed significantly better compared to other exercise and behavioural intervention subtypes, except CBT. CBT was estimated to be superior to energy conservation and other behavioural interventions. Combined exercise also had a moderate to large effect.

CONCLUSION

Treatment recommendations for balance and combined exercise are tentative as the certainty of the evidence was moderate. The certainty of the evidence for CBT was high.

Impact of Moderate Individually Tailored Physical Activity in Multiple Sclerosis Patients with Fatigue on Functional, Cognitive, Emotional State, and Postural Stability

Multiple sclerosis (MS) is a chronic disease, with fatigue syndrome as one of the main symptoms. The aim of this study was to demonstrate that moderate physical activity (MPA) may have a beneficial effect on postural stability, balance, and clinical parameters. The research group consisted of 137 randomized patients hospitalized at the Department of Neurological Rehabilitation, Medical University of Lodz. Finally, 76 patients were qualified who were divided into two groups—high fatigue (HF) and low fatigue (LF). Participants were assessed twice: before and after a 4-week MPA program using: the Expanded Disability Status Scale (EDSS), the Fatigue Severity Scale (FSS), the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA), the Beck Depression Inventory (BDI), and the Geriatric Depression Scale (GDS), and stabilometric platform tests were performed. Results obtained after the 4-week MPA program showed a positive effect of the MPA with differences between LF and HF groups. The MPA was more effective in MS patients with LF in cognitive functions, functional status, and postural stability but among HF patients in an emotional state, especially in MS patients below 65 years, although in total, both groups benefited from the MPA.

Effect of Exercise on Fatigue in Multiple Sclerosis: A Network Meta-analysis Comparing Different Types of Exercise

OBJECTIVE

A network meta-analysis (NMA) of current evidence was conducted to determine if physical exercise has a positive influence on multiple sclerosis (MS) fatigue and type of exercise with the largest effect on fatigue also according to disease severity.

DATA SOURCES

MEDLINE, Embase, SPORTDiscus, Physiotherapy Evidence Database, Cochrane Library, and Web of Science. The search strategy combined relevant terms related to (1) MS; (2) clinical trials; (3) exercise; and (4) fatigue from inception to February 2021.

STUDY SELECTION

Randomized controlled trials concerning the effectiveness of different types of exercise on total and physical fatigue in people with MS were included.

DATA EXTRACTION

The data were extracted into predesigned data extraction tables. Risk of bias was evaluated with the Cochrane Risk of Bias tool (RoB 2.0), and the Grading of Recommendations, Assessment, Development, and Evaluation tool was used to evaluate the quality of the evidence.

DATA SYNTHESIS

A total of 58 studies were examined. Data were pooled using a random-effects model. A ranking of 7 and 8 different exercise interventions for physical and total fatigue scores, respectively, was achieved. The highest effects for pairwise comparisons were for combined exercise and resistance training vs control (ranging between -0.74 and -1.24). In the NMA, combined exercise (-1.51; 95% confidence interval [CI], -2.01 to -1.01) and resistance training (-1.15; 95% CI, -1.81 to -0.49) compared with the control group achieved the highest effects for physical and total fatigue, respectively.

CONCLUSIONS

Exercise should be considered an effective fatigue management strategy. Among the different exercise modalities, combined exercise is the most effective exercise modality for improving both physical and total fatigue. Resistance training is also an effective exercise for total fatigue among people diagnosed with MS.

Central Vestibular Functions Correlate With Fatigue and Walking Capacity in People With Multiple Sclerosis

OBJECTIVE

Imbalance and fatigue are among the most common and disabling symptoms of multiple sclerosis (MS). Vestibular rehabilitation studies demonstrate not only improvements in balance but fatigue also, suggesting a relationship between central vestibular integration and fatigue. The objective of this study was to determine whether the relationship between balance and fatigue in people with MS is seen between other measures of central vestibular integration and fatigue and to understand how central vestibular integration measures interrelate.

METHODS

This cross-sectional study consisted of 40 people with MS (age = 27-55 years, Expanded Disability Severity Scale score = 1.0-6.5) who completed vestibular ocular reflex testing, subjective visual vertical testing, static posturography, dynamic gait, 2 self-report fatigue surveys, and a 6-Minute Walk Test to assess walking capacity/physical fatigue was completed. Spearman correlations were calculated between variables.

RESULTS

Measures of central vestibular integration were significantly correlated with measures of fatigue and walking capacity and with each other. The correlations between physical fatigue and central vestibular functions were larger than self-reported fatigue correlations with central vestibular functions.

CONCLUSION

The relationship between balance and fatigue extends to other measures requiring central vestibular integration, suggesting a deficit in central vestibular processing in people with MS. These measures may compliment balance assessment as outcome measures for vestibular rehabilitation in people with MS. Fatigue measures should be included in vestibular rehabilitation as secondary outcomes.

IMPACT

Correlations between central vestibular integration and fatigue in people with MS suggest that future studies of vestibular rehabilitation should include fatigue, as a secondary outcome measure as vestibular function and fatigue may share similar a similar etiology in people with MS.

Effect of Exercise on Fatigue in Multiple Sclerosis Patients: A Network Meta-analysis

Few studies have directly compared the effects of different exercise therapies on reducing fatigue in patients with multiple sclerosis. Thus, we conducted a Frequentist network meta-analysis to analyze and compare the effectiveness of different types of exercise on reducing multiple sclerosis-related fatigue. Relevant randomized controlled trials were searched in PubMed, Web of Science and Cochrane Library databases from the date of their inception up to April 1, 2021. In total, 27 articles involving 1470 participants and 10 types of interventions met the inclusion criteria. The results indicated that aquatic exercise ranked as the most effective among these interventions, and aerobic exercise had small-to-moderate effect sizes. Most of the interventions were shown to be better than the control group, except for climbing. Climbing was the only intervention that ranked worse than the controls. All of these findings merit further investigation in future clinical trials.

Comparison of efficacy of vestibular rehabilitation and noisy galvanic vestibular stimulation to improve dizziness and balance in patients with multiple sclerosis

BACKGROUND

Dizziness and imbalance are common symptoms in patients with multiple sclerosis (PwMS), and rehabilitation interventions varying greatly in effectiveness.

OBJECTIVE

To compare the effectiveness of vestibular rehabilitation therapy (VRT) and noisy galvanic vestibular stimulation (nGVS) on dizziness and balance in PwMS.

METHODS

This was a single-blind, randomized controlled trial. Twenty-four PwMS were randomly divided into groups of VRT, nGVS, and Control. The VRT and the nGVS groups underwent the intervention program. The patients were assessed with the composite score in anteroposterior and lateral directions (CS AP and LAT) obtained by sensory organization test (SOT), Dizziness Handicap Inventory (DHI), and Activities-Specific Balance Confidence Scale (ABC).

RESULTS

The VRT group showed greater improvements in CS AP and LAT, DHI total score, and ABC total score compared with the nGVS group and the control group. No significant difference was found between the nGVS group and the control group. These results were approximately stable at the 4-week follow-up.

CONCLUSIONS

These findings provided evidence for effectiveness of the VRT in improvement of dizziness and balance in PwMS. These improvements were not associated with the nGVS. Further studies are needed to assess the effectiveness of the nGVS on dizziness and balance in PwMS.

Is Aerobic or Resistance Training the Most Effective Exercise Modality for Improving Lower Extremity Physical Function and Perceived Fatigue in People With Multiple Sclerosis? A Systematic Review and Meta-analysis

OBJECTIVE

The purpose of this systematic review was to investigate whether aerobic training (AT) or resistance training (RT) is most effective in terms of improving lower limb physical function and perceived fatigue in persons with multiple sclerosis (PwMS).

DATA SOURCES

Nine databases (MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health, Allied and Complementary Medicine Database, Physiotherapy Evidence Database, SPORTDiscus, PsycINFO, Web of Science, and Scopus) were electronically searched in April 2020.

STUDY SELECTION

Included studies were randomized controlled trials (RCTs) involving PwMS attending 1 of 2 exercise interventions: AT or RT. Studies had to include at least 1 objective or self-reported outcome of lower extremity physical function and/or perceived fatigue.

DATA EXTRACTION

Data were extracted using a customized spreadsheet, which included detailed information on patient characteristics, interventions, and outcomes. The methodological quality of the included studies was independently assessed by 2 reviewers using the Tool for Assessment of Study Quality for Reporting on Exercise rating scale.

DATA SYNTHESIS

Twenty-seven articles reporting data from 22 RCTS (AT=14, RT=8) including 966 PwMS. The 2 modalities were found to be equally effective in terms of improving short walk test (AT: effect size [ES]=0.33 [95% confidence interval (CI), -1.49 to 2.06]; RT: ES=0.27 [95% CI, 0.07-0.47]) and long walk test performance (AT: ES=0.37 [95% CI, -0.04 to 0.78]; RT: ES=0.36 [95% CI, -0.35 to 1.08]), as well as in reducing perceived fatigue (AT: ES=-0.61 [95% CI, -1.10 to -0.11]; RT: ES=-0.41 [95% CI, -0.80 to -0.02]). Findings on other functional mobility tests along with self-reported walking performance were sparse and inconclusive.

CONCLUSIONS

AT and RT appear equally highly effective in terms of improving lower extremity physical function and perceived fatigue in PwMS. Clinicians can thus use either modality to target impairments in these outcomes. In a future perspective, head-to-head exercise modality studies are warranted. Future MS exercise studies are further encouraged to adapt a consensus "core battery" of physical function tests to facilitate a detailed comparison of results across modalities.

Vertigo Related to Central Nervous System Disorders

PURPOSE OF REVIEW

This article provides an overview of the numerous causes of vertigo and dizziness that are due to central nervous system (CNS) pathology and guides clinicians in formulating a differential diagnosis and treating patients with CNS causes of vertigo.

RECENT FINDINGS

Specific autoimmune vestibulocerebellar syndromes may now be tested for, and this article discusses the antibodies known to cause such syndromes. Superficial siderosis can be more accurately diagnosed with imaging studies, and treatment using iron chelation has recently been studied but has not yet been established as an effective treatment. Central autonomic network damage in the brain can cause central orthostatic hypotension in some neurodegenerative diseases, and medication has been approved for treatment.

SUMMARY

CNS causes of vertigo are numerous and important for clinicians to recognize. Examination findings are still an extremely valuable way to diagnose central vertigo; therefore, learning how to differentiate central from peripheral vertigo based on examination is an important skill. CNS causes of vertigo often have available treatments.

[Effects of rehabilitation on fatigue, disability and quality of life in people with multiple sclerosis: A systematic review]

OBJECTIVE

To assess the effectiveness of rehabilitation, highlighting the role of Occupational Therapy, in people with multiple sclerosis, in terms of disability, fatigue and quality of life.

MATERIALS AND METHODS

A literature search was carried out in the BVS, Cochrane, OT-Seeker, PubMed and PEDro databases.

INCLUSION CRITERIA

Controlled clinical trials published between January 2011 and April 2019 in Spanish or English with a score of ≥5 on the PEDro scale whose purpose was rehabilitation through the use of assistive technology, skills training, vestibular rehabilitation, behaviour modification, therapeutic education or specific Occupational Therapy interventions.

RESULTS

A total of 16 studies (1,279 subjects) were included. Rehabilitation improved patients' fatigue and disability and slightly enhanced their quality of life.

CONCLUSIONS

Rehabilitation can provide benefits to the performance of people with multiple sclerosis by reducing their perceived fatigue and disability.

LIMITATIONS

The heterogeneity of the sample, the type and duration of the interventions and variability of the instruments for measuring results.

Efficacy of Vestibular Rehabilitation in Patients With Neurologic Disorders: A Systematic Review

OBJECTIVE

The aim of this systematic review is to critically assess the effectiveness of vestibular rehabilitation (VR) administered either alone or in combination with other neurorehabilitation strategies in patients with neurologic disorders.

DATA SOURCES

An electronic search was conducted by 2 independent reviewers in the following databases: MEDLINE (PubMed), the Physiotherapy Evidence Database, and the Cochrane Database of Systematic Reviews.

STUDY SELECTION

All clinical studies carried out on adult patients with a diagnosis of neurologic disorders who performed VR provided alone or in combination with other therapies were included.

DATA EXTRACTION

Screening of titles, abstracts, and full texts and data extraction were undertaken independently by pairs of reviewers. Included studies were quality appraised using a modified version of the Newcastle-Ottawa Scale.

DATA SYNTHESIS

The summary of results was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Twelve studies were included in the review. All the included studies, with 1 exception, report that improvements provided by customized VR in subject affected by a central nervous system diseases are greater than traditional rehabilitation programs alone.

CONCLUSIONS

Because of the lack of high-quality studies and heterogeneity of treatments protocols, clinical practice recommendations on the efficacy of VR cannot be made. Results show that VR programs are safe and could easily be implemented with standard neurorehabilitation protocols in patients affected by neurologic disorders. Hence, more high-quality randomized controlled trials of VR in patients with neurologic disorders are needed.

Comparing the effects of vestibular rehabilitation with and without lavender oil scents as an olfactory stimulus on balance, fear of falling down and activities of daily living of people with multiple sclerosis: a randomized clinical trial

PURPOSE

To evaluate the effect of using lavender oil as an olfactory stimulus with vestibular rehabilitation (VR) on balance, fear of falling down, and activities of daily living of people with multiple sclerosis.

METHODS

Forty participants were randomly assigned into experimental and control groups. The experimental group did the VR exercises while smelling the lavender oil scents. The control group did the VR exercises without it. Both groups did the exercises in ten 45-min sessions. We assessed the participants with the timed up and go (TUG) test, Berg balance scale (BBS), fall efficacy scale - international (FES-I), and the 29-item multiple sclerosis impact scale (MSIS-29). We did the tests at the baseline and after the last exercise session.

RESULTS

The experimental group performed significantly better in the BBS (p = 0.007), TUG (p = 0.045), and FES-I (p = 0.016) tests as well as in the MSIS-29's psychological subscale (p = 0.034) than did the control group.

CONCLUSIONS

Using lavender oil as olfactory stimulus while doing the VR exercises can improve balance and reduce fear of falling down compared to doing the VR exercises without it in people with multiple sclerosis.Implications for rehabilitationIt seems that using lavender oil, as an olfactory stimulus, while doing vestibular rehabilitation exercises can improve balance and reduce fear of falling down in people with multiple sclerosis compared to doing the vestibular rehabilitation exercises without it.This treatment significantly alleviates the psychological effects of multiple sclerosis on daily life such as sleeping problems, feeling unwell, anxious, tense, depressed, etc.

Exercise with TENS does not augment gains in balance and strength for dancers

Electrical stimulation modulates sensory feedback and improves motor performance, at least for individuals with compromised sensorimotor function. The purpose of this study was to determine the effectiveness of a 4-wk intervention with transcutaneous electrical nerve stimulation (TENS) at improving strength and balance in dancers. Nineteen dancers completed a timed, single-leg balance test, the Y-balance test, and contractions with the hip flexor and knee extensor muscles to assess maximal strength and force steadiness. They completed 4-wks of moderate-intensity bodyweight exercises (3x/wk) and were pseudo-randomized to either a Treatment or Sham group in a single-blind design. The Treatment group received constant TENS over the hamstring muscles during the exercises, whereas the Sham group was exposed to a brief TENS current. The data were pooled due to few significant between-group differences from before to after the intervention. Most outcome measures significantly improved: hip extensor muscles were stronger (P ≤ 0.01), time stood on a single-leg with eyes closed increased (P = 0.02), and the distance reached during the Y-balance test increased (P ≤ 0.001). The improvement in scores on the Y-balance test exceeded the minimal clinically significant change. Twelve sessions of moderate-intensity bodyweight exercises improved muscle strength and balance in experienced dancers. The addition of TENS, however, did not augment the gains in function.

Vestibular rehabilitation in multiple sclerosis: study protocol for a randomised controlled trial and cost-effectiveness analysis comparing customised with booklet based vestibular rehabilitation for vestibulopathy and a 12 month observational cohort study of the symptom reduction and recurrence rate following treatment for benign paroxysmal positional vertigo

Background

Symptoms arising from vestibular system dysfunction are observed in 49–59% of people with Multiple Sclerosis (MS). Symptoms may include vertigo, dizziness and/or imbalance. These impact on functional ability, contribute to falls and significant health and social care costs. In people with MS, vestibular dysfunction can be due to peripheral pathology that may include Benign Paroxysmal Positional Vertigo (BPPV), as well as central or combined pathology. Vestibular symptoms may be treated with vestibular rehabilitation (VR), and with repositioning manoeuvres in the case of BPPV. However, there is a paucity of evidence about the rate and degree of symptom recovery with VR for people with MS and vestibulopathy. In addition, given the multiplicity of symptoms and underpinning vestibular pathologies often seen in people with MS, a customised VR approach may be more clinically appropriate and cost effective than generic booklet-based approaches. Likewise, BPPV should be identified and treated appropriately.

Methods/ design

People with MS and symptoms of vertigo, dizziness and/or imbalance will be screened for central and/or peripheral vestibulopathy and/or BPPV. Following consent, people with BPPV will be treated with re-positioning manoeuvres over 1–3 sessions and followed up at 6 and 12 months to assess for any re-occurrence of BPPV. People with central and/or peripheral vestibulopathy will be entered into a randomised controlled trial (RCT). Trial participants will be randomly allocated (1:1) to either a 12-week generic booklet-based home programme with telephone support or a 12-week VR programme consisting of customised treatment including 12 face-to-face sessions and a home exercise programme. Customised or booklet-based interventions will start 2 weeks after randomisation and all trial participants will be followed up 14 and 26 weeks from randomisation. The primary clinical outcome is the Dizziness Handicap Inventory at 26 weeks and the primary economic endpoint is quality-adjusted life-years. A range of secondary outcomes associated with vestibular function will be used.

Discussion

If customised VR is demonstrated to be clinically and cost-effective compared to generic booklet-based VR this will inform practice guidelines and the development of training packages for therapists in the diagnosis and treatment of vestibulopathy in people with MS.

Effects of Vestibular Rehabilitation on Fatigue and Activities of Daily Living in People with Parkinson's Disease: A Pilot Randomized Controlled Trial Study

One of the most disabling nonmotor symptoms in persons with Parkinson's disease is fatigue, which can decrease the quality of life by restricting the function and activities of daily living (ADL). Nonetheless, sufficient evidence for treating fatigue, including drug or nondrug treatment, is not available. In this study, we evaluated the probable effects of vestibular rehabilitation on fatigue and ADL in patients with Parkinson's disease. Methods. This was a single-blind clinical trial study in which patients with Parkinson's disease voluntarily participated based on the inclusion and exclusion criteria. The patients were randomly assigned to the case and control groups. The case group received 24 sessions of vestibular rehabilitation protocol, and conventional rehabilitation was performed in the control group (i.e., 3 sessions each week, each lasted about 60 minutes). Both groups were also given fatigue management advice. Fatigue was measured by the Parkinson Fatigue Scale (PFS) and the Modified Fatigue Impact Scale (MFIS). ADL was measured by the Functional Independence Measure (FIM). All changes were measured from the baseline at the completion of the intervention. Results. Both fatigue (P ≤ 0.001) and ADL (P ≤ 0.001) improved significantly more in the vestibular intervention group than in the control one. Conclusion. Vestibular rehabilitation may improve fatigue and ADL and therefore can be used as an effective intervention for patients with Parkinson's disease, which was also found to be well tolerated.

Better balance: a randomised controlled trial of oculomotor and gaze stability exercises to reduce risk of falling after stroke

OBJECTIVE

To assess the effect of a domiciliary program of oculomotor and gaze stability exercises on the incidence of falls and risk of fall in stroke survivors.

DESIGN

Two-arm, non-blinded parallel randomized controlled trial.

SUBJECTS

Stroke survivors older than 60 years, with positive Romberg test and autonomous gait after the stroke.

SETTING

Physiotherapy outpatient clinic of a tertiary care hospital.

INTERVENTIONS

Every participant accomplished the current rehabilitation program; the intervention group was randomly allocated into an additional three weeks intervention with a domiciliary program of oculomotor and gaze stability exercises.

MAIN MEASURES

Primary outcome was the incidence of falls through the three weeks after the intervention started; in addition, the variation of the estimated risk for falling assessed by both Berg Balance Scale (four points) and Timed Up and Go Test (four seconds) was the secondary outcome.

RESULTS

79 patients were recruited and 68 completed the protocol (control group 35; intervention group 33). During the follow up, falls were registered in 4/35 participants in the control group and no event occurred in the intervention group (P = 0.064). The estimated risk for falling decreased in 11/35 control group participants and in 28/33 intervention group participants (RR 0.37; 95%CI 0.22-0.62; P < 0.001).

CONCLUSION

After three weeks of a domiciliary program of oculomotor and gaze stability exercises, the estimated risk of falling significantly diminished and no falls occurred among the intervention group. These findings encourage further exploration of this promising intervention.

Feasibility of a smartphone app to enhance physical activity in progressive MS: a pilot randomized controlled pilot trial over three months

BACKGROUND

People with chronic progressive multiple sclerosis (CPMS) have limited options in medical treatment. Enhancing physical activity (PA) might promote neuroregeneration in multiple sclerosis (MS) and positively influence disability, thus providing an alternative to medical treatment. Previous studies indicate that evidence-based patient information (EBPI) is essential for inducing behavioral change, e.g. enhancing PA.

OBJECTIVE

To investigate feasibility of a smartphone app providing EBPI about the benefit of PA and a simple activity feedback to enhance PA in people with CPMS in a pilot randomized controlled trial over 3 months.

METHODS

Thirty-eight people with CPMS (mean age 51 years, median Expanded Disability Status Scale 4.0) were 1:1 randomized into either a control group (n = 20) or an intervention group (n = 18). The intervention group received access to a multimedia EBPI app including activity feedback, texts, figures and videos. In the control group, participants received a leaflet with unspecific information about exercising in general. The EPBI itself was designed based on a systematic review. At baseline and after 3 months, all participants underwent clinical performance tests, filled in questionnaires and received an activity monitor (Actigraph®) for 7 days. The primary endpoint was the rate of responders defined as participants with a 20% increase of physical acitivity (time of moderate or vigiorous PA-MVPA) or 20% increase of the number of steps, both assessed with the activity monitor. As secondary endpoints, we compared accelerometry, performance and questionnaires adjusted for baseline measurments between the groups (ANCOVA). Moreover, we used questionnaires to compare knowledge about exercise (activity requiring physical effort, carried out to improve or improve health and fitness) in MS, usability of the app in general and motivation towards a more active lifestyle after 3 months in both groups.

RESULTS

The groups showed significant differences in disease duration and PA according to the Godin-Leisure Time Exercise Questionnaire at baseline. After 3 months, we detected no difference in the rate of responders, which was an overall 22%. However, MVPA significantly increased in both groups (p < 0.001) and the intervention group tended to have a higher motivation towards a more active lifestyle (Cohens D = 0.7, p = 0.09) as measured by the questionnaire. Reponses also showed, that participants appreciated the app but claimed a lack of interactivity as a short-coming.

CONCLUSION

Just providing information in a multimedia smartphone app did not enhance physical activitiy more than a simple leaflet in this small pilot trial in CPMS. However, the group of app users tended to have a higher motivation towards a more active lifestyle. Overall, the concept of a smartphone app to support an active lifestyle in MS is highly appreciated by participants.

Pilates for rehabilitation in patients with multiple sclerosis: A systematic review of effects on cognition, health-related physical fitness, general symptoms and quality of life

OBJECTIVE

The aims of this systematic review is to analyze the effectiveness of Pilates intervention programs on cognitive function, health-related physical fitness, general symptoms, physical function, quality of life, and the impact Pilates can have on activities of daily living in Multiple Sclerosis (MS) patients. This review also aims to provide a synthesis of the most commonly used protocols regarding exercise parameters, such as periodicity and treatment duration.

DATA SOURCES

Systematic review of the literature was carried out following the PRISMA guidelines (PROSPERO no. CRD42017070004). A literature search was undertaken for studies that investigated the effects of Pilates training on MS patients, using databases included PubMed, Medline, Scopus and the Physiotherapy Evidence Database (PEDro) up to May 2018.

STUDY SELECTION

Three researchers independently reviewed the titles and abstract of each article to screen the papers in relation to the inclusion criteria.

DATA EXTRACTION

Data were extracted by three researchers independently. The eligible articles were read in full and their levels of evidence were evaluated using the PEDro scale.

DATA SYNTHESIS

Forty-two papers were found during the research phase. Duplicated (n = 23) or incomplete articles (n = 1) were excluded. Studies were also eliminated from the sample based on methodological approach (study design) quality assessment (n = 6). Twelve studies were ultimately selected and analyzed.

CONCLUSIONS

The majority of the studies analyzed showed positive results after Pilates training intervention and concluded that Pilates intervention is safe and effective for the treatment of dysfunction of balance, strength, quality of life, cognition, physical performance, walking and posture parameters on MS patients. The articles investigated in this review provide a scientific basis to support Pilates as an option for rehabilitation programs for MS patients.
