Effects of Pilates-Based Core Stability Training in Ambulant People With Multiple Sclerosis: Multicenter, Assessor-Blinded, Randomized Controlled Trial

Impact of Pilates suspension with self-awareness on gait and metacognition in multiple sclerosis: Randomized, single-blinded and parallel-group trial

BACKGROUND

Exercise and self-awareness are popular in the management of people with MS (pwMS). The combination of these techniques for diminishing mental and cognitive imparements doesn't apply. Since the capacity to monitor one's mind and maintain balance and efficient mobility is fundamental for carrying out the daily affairs of pwMS, in this study we assess the effect of Pilates Suspension with Self-awareness on Gait and Metacognition of pwMS. We also evaluate whether metacognition is trainable and, if so, which component of self-awareness (mental and physical) would be instrumental in this improvement.

METHOD

Twenty-four female PwMS who scored 2-6.5 on the EDSS were homogeneously divided into two intervention groups [one received pilates suspension training (PST) with Benson relaxation (PSBR), and the other received PST with Jacobson's progressive muscle relaxation (PSJR)] and one control group for 7 consecutive weeks. Relaxation training was used as a means to self-awareness. Due to the coronavirus pandemic around the world during the research process, baseline and postintervention tests and training sessions were held online. Dynamic Gait Index (DGI) and Metacognition Questionnaire-30 (MCQ-30), outcome measures were collected before and after the intervention.

RESULTS

Analysis of group data revealed significant improvement between baseline and intervention phases for Dynamic Gate Index (p = 0.002 for Benson relaxation and p = 0.001 for Jacobson's progressive muscle) and Metacognition Questionnaire-30 (p = 0.02 for Benson relaxation and p = 0.002 for Jacobson's progressive muscle).

CONCLUSIONS

With regard to multidimensional disorders of pwMS, a combined training protocol is recommended for pwMS.

An Internet- and Kinect-Based Multiple Sclerosis Fitness Intervention Training With Pilates Exercises: Development and Usability Study

BACKGROUND

Balance impairments are common in people with multiple sclerosis (MS), with reduced ability to maintain position and delayed responses to postural adjustments. Pilates is a popular alternative method for balance training that may reduce the rapid worsening of symptoms and the increased risk of secondary conditions (eg, depression) that are frequently associated with physical inactivity.

OBJECTIVE

In this paper, we aimed to describe the design, development, and usability testing of MS Fitness Intervention Training (MS-FIT), a Kinect-based tool implementing Pilates exercises customized for MS.

METHODS

MS-FIT has been developed using a user-centered design approach (design, prototype, user feedback, and analysis) to gain the target user's perspective. A team composed of 1 physical therapist, 2 game programmers, and 1 game designer developed the first version of MS-FIT that integrated the knowledge and experience of the team with MS literature findings related to Pilates exercises and balance interventions based on exergames. MS-FIT, developed by using the Unity 3D (Unity Technologies) game engine software with Kinect Sensor V2 for Windows, implements exercises for breathing, posture, and balance. Feedback from an Italian panel of experts in MS rehabilitation (neurologists, physiatrists, physical therapists, 1 statistician, and 1 bioengineer) and people with MS was collected to customize the tool for use in MS. The context of MS-FIT is traveling around the world to visit some of the most important cities to learn the aspects of their culture through pictures and stories. At each stay of the travel, the avatar of a Pilates teacher shows the user the exercises to be performed. Overall, 9 people with MS (n=4, 44% women; mean age 42.89, SD 11.97 years; mean disease duration 10.19, SD 9.18 years; Expanded Disability Status Scale score 3.17, SD 0.75) were involved in 3 outpatient user test sessions of 30 minutes; MS-FIT's usability was assessed through an ad hoc questionnaire (maximum value=5; higher the score, higher the usability) evaluating easiness to use, playability, enjoyment, satisfaction, and acceptance.

RESULTS

A user-centered design approach was used to develop an accessible and challenging tool for balance training. All people with MS (9/9, 100%) completed the user test sessions and answered the ad hoc questionnaire. The average score on each item ranged from 3.78 (SD 0.67) to 4.33 (SD 1.00), which indicated a high usability level. The feedback and suggestions provided by 64% (9/14) of people with MS and 36% (5/14) of therapists involved in the user test were implemented to refine the first prototype to release MS-FIT 2.0.

CONCLUSIONS

The participants reported that MS-FIT was a usable tool. It is a promising system for enhancing the motivation and engagement of people with MS in performing exercise with the aim of improving their physical status.

Orthotic shorts for improving gait and walking in multiple sclerosis: a feasibility study

PURPOSE

To explore the acceptability and potential efficacy of orthotic shorts in people with multiple sclerosis.

MATERIALS AND METHODS

This mixed-methods, cross-over study utilised qualitative data to investigate acceptability, including perceived effectiveness. Quantitative data included wear times, self-selected walking speed, spatiotemporal gait parameters, and participant-perceived walking ability. Fifteen participants were assessed with and without two pairs of custom-made shorts: one designed as an orthotic and a second looser pair. Each were worn at home for two weeks. Semi-structured interviews were conducted at the first and final appointments. Quantitative data were analysed using Cohen's d; qualitative analysis used a thematic framework. A triangulation protocol integrated qualitative and quantitative data.

RESULTS

Orthotic shorts were acceptable to most users who described improved control, stability, and function. Where shorts were less acceptable, this was due to restriction of hip flexion or appearance. Effect sizes were in the moderate category for participant-perceived walking ability and for those spatiotemporal gait parameters that reflect mediolateral stability. Small effect sizes were seen for walking speed and related spatiotemporal parameters, such as step length.

CONCLUSION

Orthotic shorts are acceptable and potentially efficacious for improving walking, stability, and function in people with multiple sclerosis. Further research and design development are warranted.Implications for rehabilitationOrthotic shorts are a type of fabric orthosis that have not been previously researched but might assist pelvic stability.Orthotic shorts appear to be acceptable to those people with multiple sclerosis who perceive themselves to be unstable around the trunk and hips.Orthotic shorts might improve gait stability and self-perceived walking ability.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

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

OBJECTIVE

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

DESIGN

Two-group randomized controlled trial.

SETTING

General community and referral center.

PARTICIPANTS

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

INTERVENTIONS

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

OUTCOME MEASURES

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

RESULTS

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

CONCLUSION

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

Factors Associated With Treatment-Related Changes in Voice Volume in People With Multiple Sclerosis

BACKGROUND

Vocal disorders are frequent in people with multiple sclerosis (MS). Cognitive impairment, fatigue, depression, and other clinical characteristics can be associated with treatment effectiveness in rehabilitation. Finding baseline characteristics that identify those who are responding to treatment can help the clinical decision-making process, which can then help improve the effectiveness of voice treatment. We developed a model to identify factors associated with treatment-related improvement on voice intensity in people with MS.

METHODS

Data are from a randomized controlled trial of the effects of voice therapy. Forty-four people with MS were enrolled and randomized to receive Lee Silverman Voice Treatment LOUD, specifically addressing voice intensity, or conventional speech-therapy group. Voice intensity (dB) was measured during monologue before and after treatment and was used to differentiate those who responded (posttreatment voice intensity > 60 dB) from those who did not. Possible associated factors were cognitive impairment, fatigue, depression, disability, and disease duration. Associations were assessed by univariate logistic regression and univariate and multivariate linear regressions.

RESULTS

Mean ± SD monologue voice intensity is improved in the whole sample (before rehabilitation: 51.8 ± 4.2 dB; and after rehabilitation 57.0 ± 6.5 dB; P < .001), and 11 people with MS (27.5%) responded to treatment. Specificity of treatment was associated with the return to normal voice intensity (OR, 14.28; 95% CI, 12.17-309.56) and we found a linear association between voice improvement and the specificity of treatment (6.65 [SE = 1.54] dB; P < .05). Moreover, the analysis revealed a nonlinear association between improvement and fatigue, suggesting increased benefits for people with MS with moderate fatigue. Other factors were not significantly associated with treatment effectiveness.

CONCLUSIONS

Moderate fatigue and the specificity of the intervention seem to be key factors associated with clinically relevant improvement in voice intensity even in people with MS with a high level of disability and long disease duration.

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.

Pilates-based exercises for gait and balance in ambulant children with cerebral palsy: feasibility and clinical outcomes of a randomised controlled trial

PURPOSE

To determine if Pilates-based exercise classes could be feasible and effective in changing gait kinematics and balance in ambulant children with Cerebral Palsy (CP).

MATERIALS AND METHODS

A single-blind multi-centre randomised controlled trial compared a four-week, twice-weekly Pilates-based exercise class to a usual exercise control, for ambulant children with CP. Clinical outcome measures were three-dimensional trunk and lower limb kinematics during walking on level ground, uneven ground and crossing an obstacle; and clinical balance measures. Feasibility outcomes were adherence and enjoyment.

RESULTS

Forty-six children (29 male, mean age 10 years 8 months (range 7-17 years), 23 per group) participated. After the four-week intervention, there were no significant between-group differences in trunk or lower limb gait kinematics. Differences were detected in Berg Balance Scale (1.38 points, 95% CI 0.58-2.18) and Functional Walking Test (1.40 points, 95% CI 0.58-2.22), but they were less than the minimum clinically important difference and therefore clinically insignificant. Median class attendance was 5/8 classes.

CONCLUSION

Pilates-based exercises did not change lower limb or trunk kinematics during walking in children with CP and had a clinically insignificant impact on balance. Lower than anticipated adherence prompts consideration of more flexible delivery of future interventions. Implications for RehabilitationAmbulant children with CP can experience impairment of trunk control, negatively impacting balance and gait.In this study, Pilates-based exercise classes did not change kinematics of the trunk or lower limbs during walking and led to negligible improvement in functional balance.Children did not manage to do their Home Exercise Programme, indicating that Pilates-based exercise should be delivered within supervised practice.Children missed on average one in three classes due to unforeseen circumstances, so this should be anticipated when planning group classes.

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

INTRODUCTION

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

EVIDENCE ACQUISITION

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

EVIDENCE SYNTHESIS

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

CONCLUSIONS

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

Therapeutic Effects of the Pilates Method in Patients with Multiple Sclerosis: A Systematic Review

The Pilates Method is a rehabilitation tool with verified benefits in pain management, physical function, and quality of life in many different physiotherapy areas. It could be beneficial for patients with multiple sclerosis (pwMS). The aim of the study was to summarize current evidence for the effectiveness of Pilates in pwMS. A comprehensive search of Cinahl, Scopus, Web of Science, PEDro, and PubMed (including PubMed Central and Medline) was conducted to examine randomized controlled trials (RCT) that included Pilates intervention in multiple sclerosis. The PEDro scale and the Cochrane risk-of-bias tool, RoB-2, were used to evaluate risk of bias for RCT. Twenty RCT (999 patients) were included. Ten were of good quality (PEDro), and seven had low risk of bias (RoB-2). Pilates improves balance, gait, physical-functional conditions (muscular strength, core stability, aerobic capacity, and body composition), and cognitive functions. Fatigue, quality of life, and psychological function did not show clear improvement. There was good adherence to Pilates intervention (average adherence ≥ 80%). Cumulative data suggest that Pilates can be a rehabilitation tool for pwMS. High adherence and few adverse effects were reported. Future research is needed to develop clinical protocols that could maximize therapeutic effects of Pilates for pwMS.

Effect of dynamic neuromuscular stabilization on balance and trunk function in people with multiple sclerosis: protocol for a randomized control trial

Background

Multiple sclerosis is a chronic and disabling neurological disease among young people. One of the major complaints in patients with multiple sclerosis (PWMS) is falling. There are a number of factors that risk factors for falling, including balance disorder and spasticity. Core stability (CS) exercises such as trunk muscle strengthening exercises can improve balance and mobility and reduce falling. Dynamic neuromuscular stabilization (DNS) exercise is a new functional rehabilitation strategy that optimizes motor function based on the principles of developmental kinesiology. This trial will evaluate the effectiveness of DNS in comparison to CS on balance, spasticity, and falling in PWMS.

Methods

A total of 64 PWMS, between 30 and 50 years old and expanded disability status scale (EDSS) between 2 to 5, will be recruited from neurophysiotherapy clinic, Faculty of Rehabilitation Sciences, Iran University of Medical Sciences to participate in this 2-armed parallel study. Participants will be randomly divided into two groups to receive CS exercise or DNS exercise. All participants will receive exercise treatment for 15 sessions during a period of 5 weeks (3 sessions per week). Primary outcome measures will be balance. Falling rate, fear of falling, patient mobility, as well as spasticity, will be measured as secondary outcomes. All outcome measures will be measured at baseline, the day after the completion of the 15th session, and after 17 weeks.

Discussion

Dynamic neurostabilization exercises utilize the subconscious stimulation of special zones to reflexively mediate the diaphragm and other core stabilization muscles, which is extremely effective for individuals with reduced somatosensory or movement awareness. Findings from the proposed study are expected to benefit the knowledge base of the physiotherapist, and it can be a good alternative for the rehabilitation program and even reduce medication use in patients with multiple sclerosis. These exercises are easy to understand and applicable for these patients and their partners as well.

Trial registration

The trial was registered in the Iran registry organization with code IRCT20140222016680N5 and was approved on April 7^th, 2020. Address: IRCT administration team, Central Library Building, Iran University Campus, Hemmat Freeway, next to Milad tower, Tehran, Iran. postal code:14496-14535.

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.

Do Pilates exercises improve balance in patients with multiple sclerosis? A systematic review and meta-analysis

INTRODUCTION AND PURPOSE

Balance problems are common in people with multiple sclerosis (MS). Pilates can also be treatment strategy for people with MS, but there is inadequate evidence to support or refute the efficacy of Pilates, especially on balance in MS patients. The aim of this study was to conduct a systematic review and meta-analysis to determine the effects of Pilates exercises on balance in people with MS.

METHODS

We conducted a literature search of the Cochrane Library, MEDLINE (EBSCO), Physiotherapy Evidence Database (PEDro), CINAHL (EBSCO), PUBMED, OVID, Science Direct, and Scopus databases using the following search terms: multiple sclerosis, Pilates, core stability, balance, equilibrium, postural control. All content from the date of database inception to March 2021 was included in the search.

RESULTS

The initial search strategy based on date range and language yielded 246 relevant records and eight of them were about both Pilates and MS. According to this evaluation, we found the significant advantage of Pilates on balance in patients with MS, when compared to the control group in the Berg Balance Scale (SMD=1.017; 95% CI=-0.040, 1.994; p = 0.041), Activities-Specific Balance Confidence Scale (SMD=0.604; 95% CI=-0.078, 1.130; p = 0.024), Timed Up and Go Test (SMD=0.944; 95% CI=-0.022, 1.867; p = 0.045). But in the Functional Reach Test (SMD=1.846; 95% CI=-0.080, 3.772; p = 0.060), we did not found any difference between groups.

CONCLUSIONS

Pilates exercises might be an optional method for improving balance in MS patients, however, we need further robust studies to prove whether it is more effective than other physiotherapy interventions.

Observational Screening Guidelines and Smartphone Accelerometer Thresholds to Establish the Intensity of Some of the Most Popular Core Stability Exercises

The lack of training load control, mainly exercise intensity, is one of the main limitations of core stability (CS) programs, which makes the training individualization and the analysis of the dose-response relationship difficult. The objectives of this study were to assess the inter-and intra-rater agreement when using new observational screening guidelines to decide if a core stability exercise represents an adequate training intensity level for a given participant. Besides, the relationship between experts' ratings based on these criteria and pelvic accelerations recorded with a smartphone accelerometer was also analyzed. Ten healthy physically active participants with a smartphone accelerometer placed on their pelvis were video-taped while performing a progression of seven variations of the front bridge, back bridge, side bridge and bird-dog exercises. Two expert and four non-expert raters watched the videos and used the observational screening guidelines to decide for each exercise variation if it represented an adequate training intensity level or not. In order to analyze the inter-and intra-rater agreement, several Kappa (κ) statistics were used. Receiver operating characteristic (ROC) curves to explore if the accelerometry allowed to establish pelvic acceleration thresholds representing the minimum level of exercise intensity for CS training. Cut-off acceleration values were calculated balancing sensitivity (Se) and 1-specifity (1-Sp) indexes (i.e., Youden index) or minimizing 1-Sp. The intra-and inter-rater analysis showed a substantial-high level of agreement with a prevalence-adjusted bias-adjusted Kappa > 0.69. The ROC curves showed that the acceleration thresholds for the bridging exercises were very similar, with global cut-off values of 0.35 m/s² (Se = 82%; 1-Sp = 15%) when using the Youden Index and of 0.50 m/s² when minimizing 1-Sp (Se = 31%), whilst the bird-dog exercise showed lower cut-off values (Youden Index: 0.21 m/s², Se = 90%, 1-Sp = 16%; minimizing 1-Sp: 0.32 m/s², Se = 40%). Overall, this study provides observational screening guidelines and smartphone accelerometer thresholds to facilitate the decision-making process when setting the intensity of some of the most popular core stability exercises in young physically active individuals.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Participant experiences of eight weeks of supervised or home-based Pilates among people with multiple sclerosis: a qualitative analysis

PURPOSE

An exploratory qualitative study investigating participants' experiences of a feasibility study of supervised and home-based Pilates.

METHODS

All 10 females who participated in an eight-week supervised (n = 4) or home-based Pilates (n = 6) program were invited and agreed to be interviewed. Data were collected via semi-structured interviews and researcher observations of participant experiences. Data were analysed using codebook thematic analysis framework.

RESULTS

Two domain summaries emerged: (1) the suitability of home-based Pilates in particular for this population. Participants indicated that supervised and home-based Pilates was a safe, intensity-appropriate, and implementable exercise method to improve mental health outcomes among persons with multiple sclerosis (PwMS), and (2) the benefits experienced by PwMS while participating in Pilates. Home-based Pilates reduced both exercise participation and accessibility barriers commonly experienced by PwMS. Furthermore, PwMS reported improvements in mental health outcomes following Pilates, in both exercise environments.

CONCLUSIONS

PwMS reported experiencing improved mood following regular Pilates training and indicated that home-based in particular reduced barriers regularly experienced by this population. Results support Pilates as a feasible exercise modality providing potential mood improvements among PwMS. Future appropriately powered home-based randomised controlled trials to further explore the effects of Pilates training on mental health among PwMS with minimal-to-mild mobility disability are warranted.Implications for RehabilitationParticipants in this study described the mental health benefits experienced from engaging in Pilates, a non-traditional exercise modality.Home-based Pilates overcame participatory and accessibility barriers to exercise among people with multiple sclerosis (MS).Participants valued that Pilates was low intensity and did not exacerbate fatigue.Home-based Pilates is a feasible exercise method for people with MS with minimal-to-mild mobility disability.

Rehabilitation in multiple sclerosis in 2021

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

Retention of Physical Gains in the Community Following Physical Training for Multiple Sclerosis: A Systematic Review and Implications

Multiple sclerosis (MS) is a progressive neurological illness whose typically young adult onset results in a nearly entire lifetime of worsening disability. But despite being an unrelenting neurodegenerative disease, numerous clinical trials over the past 40 years for MS have vigorously attempted to improve or at least stabilize declining physical function. Although the vast majority of the studies assessed training effects only within controlled laboratory or clinic settings, in recent years a growing interest has emerged to test whether newer therapies can instead benefit real-life activities in the community. Nonetheless, comparatively little attention has been paid to whether the training gains can be retained for meaningful periods. This review discusses the comparative success of various physical training methods to benefit within-community activities in MS, and whether the gains can be retained long afterward. This review will suggest future research directions toward establishing efficacious treatments that can allow persons with MS to reclaim their physical abilities and maximize functionality for meaningful periods.

Efficacy of core stability versus task oriented trainings on balance in ataxic persons with multiple sclerosis. A single blinded randomized controlled trial

BACKGROUND

Balance and ataxic symptoms are commonly encountered in people with multiple sclerosis (PwMS). Many intervention approaches have been proposed to address balance in PwMS. The purpose of this study was to investigate the efficacy of adding core stability versus task oriented trainings on traditional approaches on balance in ataxic PwMS.

METHODS

Forty five ataxic relapsing-remitting PwMS from both sexes were randomly assigned into three identical groups. Control group (CG) treated with conventional balance exercise program; study groups I (GI) and II (GII) received respectively additional training using core stability exercises and task oriented trainings. Outcome measures recorded pre and post study period included stability index (SI), anterior posterior stability index (APSI), and mediolateral stability index (MLSI) using Biodex stability system in addition to the Berg balance scale (BBS).

RESULTS

Post treatment, the results indicated significant improvement in (SI) and (APSI) (p<0.05), and non-significant improvement (p>0.05) in (MLSI) and BBS in CG. In GI and GII there was a significant improvement in all balance measures (p<0.05). Comparison of post treatment results between groups indicated a significant improvement of GII compared to CG in all study measures, GI showed non- significant difference in all balance measures compared to the CG(P>0.05).

CONCLUSION

In PwMS balance rehabilitation should be multimodal; core stability exercises and task-oriented training in addition to conventional balance training are effective to improve balance and should be considered as an essential part of the training program for balance rehabilitation in ataxic PwMS. Task-oriented training in addition to conventional balance rehabilitation seem to be a favorable approach.

Postural control quantification in minimally and moderately impaired persons with multiple sclerosis: The reliability of a posturographic test and its relationships with functional ability

BACKGROUND

Postural control has been associated with the functional impairment in persons with multiple sclerosis (pwMS). However, there is a need for reliable methods to assess postural control in early stages of the disease, when subtle changes can be difficult to detect. The aims of this study were to assess the absolute and relative reliability of a standing and a sitting posturographic protocol in minimally (Expanded Disability Status Scale ≤ 2) and moderately (2.5 ≤ Expanded Disability Status Scale ≤ 4) impaired pwMS, and to analyze relationships among postural control and functional mobility and gait performance.

METHODS

To assess postural control in an upright stance, 14 minimally and 16 moderately impaired pwMS performed six 70 s trials in tandem stance, 3 with their weaker leg behind (TS_WL) and 3 with their stronger leg behind (TS_SL). Additionally, participants completed five 70 s trials using an unstable sitting protocol (US) to assess trunk stability. The mean radial errors of TS_WL, TS_SL, and US trials were calculated as postural control indexes. Furthermore, participants performed the Timed Up and Go test (TUG) and the Timed 25-foot Walk test (T25FW) to measure their functional mobility and gait speed, respectively. Reliability was evaluated using the intraclass correlation coefficient (ICC_3,1) and the standard error of measurement (SEM). Analyses of variances were carried out to assess between-group differences. Hedges' g index (d_g) was used to estimate the effect size of differences. Pearson correlation analyses (r) were performed to examine the relationships among the postural control and the functional tests.

RESULTS

Posturographic tests showed a high reliability in both minimally (0.87 ≤ ICC ≤ 0.92; 9.32% ≤ SEM ≤ 11.76%) and moderately (0.80 ≤ ICC ≤ 0.92; 10.33% ≤ SEM ≤ 15.33%) impaired pwMS. Similarly, T25FW and TUG displayed a high consistency in minimally (0.89 ≤ ICC ≤ 0.94; 3.43% ≤ SEM ≤ 5.17%) and moderately (0.85 ≤ ICC ≤ 0.93; 5.57% ≤ SEM ≤ 6.56%) impaired individuals. Minimally impaired pwMS showed a better performance on the TUG, T25FW, and TS_WL than moderately impaired individuals (p < 0.05; d_g ≥ 0.8). The TS_WL, TS_SL, and US variables correlated with TUG scores (0.419 ≤ r ≤ 0.604; p < 0.05), but TS_WL also correlated with T25FW scores (r = 0.53; p < 0.01). Furthermore, US scores correlated with both tandem stance parameters (TS_WL: r = 0.54, p < 0.01; TS_SL: r = 0.43, p < 0.05).

CONCLUSION

Tandem and sitting posturographic tests provide reliable measures of postural control in pwMS, even in individuals with a homogeneous disease profile. Gait speed, functional mobility, and weaker leg status seem decisive in assessing the degree of physical activity limitation in pwMS. Finally, although trunk stability does not seem to be so affected by the course of the disease, it remains relevant for postural control and functional capacity.

Effect of twelve weeks pilates training on functional balance of male patients with multiple sclerosis: Randomized controlled trial

OBJECTIVE

Pilates training has several well-known benefits for people with Multiple Sclerosis (MS). However, its effect on functional balance is unclear. The present study aimed to evaluate the effect of pilates exercises on the functional balance of male patients with MS.

METHOD

In the present parallel group randomized controlled trial, 30 men with MS were recruited from a local corrective exercise clinic in Tehran, Iran, and randomized into Pilates training group (N = 15), and control group (N = 15). At baseline, the age range was 25-40 years, and disability score index was 3-5.

INTERVENTION

The intervention group received Pilates exercises including the extension of the thoracic spine, abdominal strengthening, core stabilizing exercises, upper and lower limb, and posture exercises for 12 weeks.

OUTCOMES

Functional balance assessments including Berg's Balance Scale (BBS) test, Timed Up and Go (TUG) test, and Functional Reach Test (FRT) were measured at the baseline and after 12 weeks.

RESULTS

At a 12-week follow-up, a significant between-group difference was observed in favor of the Pilates training group for the functional balance scores (P < 0.05), while no adverse or harmful events were reported in any group.

CONCLUSION

Pilates training increases the functional balance of MS patients, and decreases known risk factors for falls among the patients in this group, which may have the potential to reduce therapeutic costs and can be considered as a complementary therapeutic approach for physical therapists and corrective exercise experts.

A self-management programme to reduce falls and improve safe mobility in people with secondary progressive MS: the BRiMS feasibility RCT

BACKGROUND

Balance, mobility impairments and falls are common problems for people with multiple sclerosis (MS). Our ongoing research has led to the development of Balance Right in MS (BRiMS), a 13-week home- and group-based exercise and education programme intended to improve balance and encourage safer mobility.

OBJECTIVE

This feasibility trial aimed to obtain the necessary data and operational experience to finalise the planning of a future definitive multicentre randomised controlled trial.

DESIGN

Randomised controlled feasibility trial. Participants were block randomised 1 : 1. Researcher-blinded assessments were scheduled at baseline and at 15 and 27 weeks post randomisation. As is appropriate in a feasibility trial, statistical analyses were descriptive rather than involving formal/inferential comparisons. The qualitative elements utilised template analysis as the chosen analytical framework.

SETTING

Four sites across the UK.

PARTICIPANTS

Eligibility criteria included having a diagnosis of secondary progressive MS, an Expanded Disability Status Scale (EDSS) score of between ≥ 4.0 and ≤ 7.0 points and a self-report of two or more falls in the preceding 6 months.

INTERVENTIONS

Intervention - manualised 13-week education and exercise programme (BRiMS) plus usual care. Comparator - usual care alone.

MAIN OUTCOME MEASURES

Trial feasibility, proposed outcomes for the definitive trial (including impact of MS, mobility, quality of life and falls), feasibility of the BRiMS programme (via process evaluation) and economic data.

RESULTS

A total of 56 participants (mean age 59.7 years, standard deviation 9.7 years; 66% female; median EDSS score of 6.0 points, interquartile range 6.0-6.5 points) were recruited in 5 months; 30 were block randomised to the intervention group. The demographic and clinical data were broadly comparable at baseline; however, the intervention group scored worse on the majority of baseline outcome measures. Eleven participants (19.6%) withdrew or were lost to follow-up. Worsening of MS-related symptoms unrelated to the trial was the most common reason (n = 5) for withdrawal. Potential primary and secondary outcomes and economic data had completion rates of > 98% for all those assessed. However, the overall return rate for the patient-reported falls diary was 62%. After adjusting for baseline score, the differences between the groups (intervention compared with usual care) at week 27 for the potential primary outcomes were MS Walking Scale (12-item) version 2 -7.7 [95% confidence interval (CI) -17.2 to 1.8], MS Impact Scale (29-item) version 2 (MSIS-29vs2) physical 0.6 (95% CI -7.8 to 9) and MSIS-29vs2 psychological -0.4 (95% CI -9.9 to 9) (negative score indicates improvement). After the removal of one outlier, a total of 715 falls were self-reported over the 27-week trial period, with substantial variation between individuals (range 0-93 falls). Of these 715 falls, 101 (14%) were reported as injurious. Qualitative feedback indicated that trial processes and participant burden were acceptable, and participants highlighted physical and behavioural changes that they perceived to result from undertaking BRiMS. Engagement varied, influenced by a range of condition- and context-related factors. Suggestions to improve the utility and accessibility of BRiMS were highlighted.

CONCLUSIONS

The results suggest that the trial procedures are feasible and acceptable, and retention, programme engagement and outcome completion rates were sufficient to satisfy the a priori progression criteria. Challenges were experienced in some areas of data collection, such as completion of daily diaries.

FUTURE WORK

Further development of BRiMS is required to address logistical issues and enhance user-satisfaction and adherence. Following this, a definitive trial to assess the clinical effectiveness and cost-effectiveness of the BRiMS intervention is warranted.

Effectiveness of Physical Therapy Interventions in Reducing Fear of Falling Among Individuals With Neurologic Diseases: A Systematic Review and Meta-analysis

OBJECTIVE

To summarize the effectiveness of physical therapy interventions to reduce fear of falling (FOF) among individuals living with neurologic diseases.

DATA SOURCES

PubMed, Physiotherapy Evidence Database, Scopus, Web of Science, PsycINFO, Cumulative Index to Nursing and Allied Health, and SportDiscuss were searched from inception until December 2019.

STUDY SELECTION

Clinical trials with either the primary or secondary aim to reduce FOF among adults with neurologic diseases were selected.

DATA EXTRACTION

Potential articles were screened for eligibility, and data were extracted by 2 independent researchers. Risk of bias was assessed by the Cochrane Risk of Bias tool for randomized controlled trials and the National Institutes of Health Quality Assessment Tool for pre-post studies. A meta-analysis was performed among trials presenting with similar clinical characteristics. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) was used to rate the overall quality of evidence.

RESULTS

Sixty-one trials with 3954 participants were included in the review and 53 trials with 3524 participants in the meta-analysis. The included studies presented, in general, with a low to high risk of bias. A combination of gait and balance training was significantly more effective compared with gait training alone in reducing FOF among individuals with Parkinson disease (PD) (mean difference [MD]=11.80; 95% CI, 8.22-15.38; P<.001). Home-based exercise and leisure exercise demonstrated significant improvement in reducing FOF over usual care in multiple sclerosis (MS) (MD=15.27; 95% CI, 6.15-24.38; P=.001). No statistically significant between-groups differences were reported among individuals with stroke and spinal cord injury. The overall quality of evidence presented in this review ranges from very low to moderate according to the assessment with the GRADE approach.

CONCLUSIONS

Gait with lower limb training combined with balance training is effective in reducing FOF in individuals with PD. Also, home-based or leisure exercise is effective among individuals with MS. However, because of several limitations of the included studies, further research is needed to examine the effectiveness of FOF intervention among individuals with neurologic diseases.

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.

Adherence and drop-out in randomized controlled trials of exercise interventions in people with multiple sclerosis: A systematic review and meta-analyses

BACKGROUND

The short-term benefits of exercise in people with multiple sclerosis (MS) are well established. To sustain benefits exercise needs to continue long-term. Despite important clinical implications, no systematic reviews have synthesized evidence on adherence and drop-out in MS exercise interventions.

OBJECTIVES

1) To summarize reported adherence and drop-out data from randomized controlled trials (RCTs) of exercise interventions, and 2) identify moderators related to adherence and drop-out.

METHODS

Nine databases were electronically searched in October 2018. Included studies were RCTs of exercise interventions in adults with MS published from January 1993 to October 2018. Abstracts and full texts were independently screened and selected for inclusion by two reviewers. Methodological quality was assessed using the TESTEX rating scale.

RESULTS

Ninety three articles reporting 81 studies were included. Forty one studies (51%) reported both adherence and drop-out data during the intervention period with three (4%) also reporting follow-up data. Of the 41 studies, < 25% pre-defined adherence or described how adherence was measured. Meta-analyses of 59 interventions (41 studies) showed a pooled adherence estimate of 0.87 (95% CI 0.83 to 0.90) and 0.73 (CI 0.68-0.78) when including drop-outs. Mean age, proportion of females and intervention duration were inversely associated with adherence.

CONCLUSION

Little consensus existed on definition of adherence or determination of drop-out in MS exercise studies, with reporting generally of poor quality, if done at all. Hence it is largely unknown what can moderate adherence and whether exercise continued following an exercise intervention. Researchers should ensure clear transparent measurement and reporting of adherence and drop-out data in future trials.

Biofeedback Based Home Balance Training can Improve Balance but Not Gait in People with Multiple Sclerosis

Background

Impaired balance is common in people with multiple sclerosis (MS) and can be present even in those with a mild disability level. With increasing disability, gait, and balance impairment progress, and lead to increased risk of falls. In some recent studies, interactive commercial video games were used for improving balance, but their limitation is their lack of individual training parameter settings needed for rehabilitation purposes. The aim of this study was to evaluate the feasibility and effect of balance exercise in the home setting using the rehabilitation Homebalance® system.

Methods

A single-centre, controlled, single blind study with allocation to intervention group or to control group was utilised. Participants were assessed at baseline, after four weeks of home-based balance training, and follow-up after four weeks. The primary outcomes were the Berg Balance Test (BBT). The secondary outcome measures included the Mini-BESTest, Timed Up, and Go Test (part of Mini-BESTest), and spatio-temporal gait parameter evaluation using the GAITRite instrument. The patient reported outcomes (PRO) included the 12-Item MS Walking Scale, Activities-specific Balance Confidence Scale, and the Falls Efficacy Scale.

Results

A total of 39 people with Multiple Sclerosis (10 men) were enrolled into the study. The mean age of participants was 40.69 ± 10.2 years, with a mean disease duration 14.76 ± 9.1 years and mean disability level 3.8 ± 1.9 EDSS (EDSS range 1.5–7). Statistically significant improvements within the home exercise group were present for the BBT and the Mini-BESTest. This improvement was more significant in the subgroup with moderate and higher disability (EDSS 4.5–7). All other gait parameters and PRO did not show any improvement. Follow-up assessment after four weeks showed that the reached improvement persisted for a short time period after finishing the regular training regimen.

Conclusion

In comparison with no intervention, a short-term programme of home-based balance training using Homebalance® improved balance but not gait performance in a group of people with MS. It seems that home-based balance training tailored according to individual needs by a physiotherapist may be a future approach to consider for telerehabilitation of people with MS.

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

BACKGROUND

Balance and trunk control are often impaired in individuals with multiple sclerosis (MS). Interventions addressing these issues are needed.

OBJECTIVE

The objective of this study was to compare the immediate and long-term effects of a 6-week individualized, group-based, comprehensive core stability intervention (GroupCoreDIST) with standard care on balance and trunk control in individuals with MS.

DESIGN

This study was a prospective, assessor-masked, randomized controlled trial.

SETTING

The GroupCoreDIST intervention was conducted by 6 physical therapists in 6 municipalities in Norway. Standard care included the usual care for individuals with MS in the same municipalities. Assessments at all time points took place at a Norwegian hospital.

PARTICIPANTS

Eighty people with Expanded Disability Status scores of 1 to 6.5 participated in this trial.

INTERVENTION

Randomized, concealed allocation was used to assign the participants to the GroupCoreDIST intervention (n = 40) or to standard care (n = 40). The GroupCoreDIST intervention was conducted with groups of 3 participants (1 group had 4 participants), for 60 minutes 3 times per week.

MEASUREMENTS

Assessments were undertaken at baseline and at weeks 7, 18, and 30. Outcomes were measured with the Trunk Impairment Scale-Norwegian Version, Mini Balance Evaluation Systems Test, and Patient Global Impression of Change-Balance. Repeated-measures mixed models were used for statistical analysis.

RESULTS

One individual missed all postintervention tests, leaving 79 participants in the intention-to-treat analysis. GroupCoreDIST produced significant between-group effects on the mean difference in the following scores at 7, 18, and 30 weeks: for Trunk Impairment Scale-Norwegian Version, 2.63 points (95% confidence interval [CI] = 1.89-3.38), 1.57 points (95% CI = 0.81-2.33), and 0.95 point (95% CI = 0.19-1.71), respectively; for Mini Balance Evaluation Systems Test, 1.91 points (95% CI = 1.07-2.76), 1.28 points (95% CI = 0.42-2.15), and 0.91 points (95% CI = 0.04-1.77), respectively; and for Patient Global Impression of Change-Balance, 1.21 points (95% CI = 1.66-0.77), 1.02 points (95% CI = 1.48-0.57), and 0.91 points (95% CI = 1.36-0.46), respectively.

LIMITATIONS

Groups were not matched for volume of physical therapy.

CONCLUSIONS

Six weeks of GroupCoreDIST improved balance and trunk control in the short and long terms compared with standard care in individuals who were ambulant and had MS. The intervention is an effective contribution to physical therapy for this population.

Factors influencing balance improvement in multiple sclerosis rehabilitation: A pragmatic multicentric trial

OBJECTIVES

Treatment for progressive multiple sclerosis (pMS) is a key area of research. To date, whether MS type and the rehabilitation setting are associated with worse or better response to rehabilitation is unclear. We aimed to understand the association between balance and MS type, in/outpatient treatment and specificity of the intervention.

METHODS

We assessed 150 people with MS before and after in/outpatient rehabilitation. The Berg Balance Scale (BBS) was used to discriminate between responders (≥+3-point improvement in BBS score; a clinically meaningful improvement) and non-responders to specific or non-specific balance rehabilitation. Factors associated with balance were analyzed by univariate and multivariable logistic regression analyses, estimating odds ratios (ORs) and 95% confidence intervals (CIs).

RESULTS

Balance improved after rehabilitation: median (quartile 1 [Q1]-Q3) BBS score pre- and post-rehabilitation of 49 (45-53) and 52 (47-55) (P<0.001). Univariate logistic analysis revealed a clinically meaningful improvement in balance associated with pMS (OR 2.21 [95% CI 1.09-4.05]), inpatient therapy (0.41 [0.19-0.84]), using a walking aid (1.68 [1.06-2.69]), and low baseline BBS score (0.86 [0.81-0.92]). On multivariable analysis, probability of improvement was similar for participants with pMS and the relapsing-remitting form but was associated with low baseline BBS score and specific treatment (OR 0.81 [95% CI 0.74-0.89] and 5.66 [1.79-21.5]).

CONCLUSION

A clinically meaningful improvement in balance was more likely when MS individuals with moderate to high disability had specific exercises targeting balance, but MS type did not influence the outcome.

Short-term effects of core stability training on the balance and ambulation function of individuals with chronic spinal cord injury: a pilot randomized controlled trial

BACKGROUND

To investigate the effects of core stability training (CST) on an unstable support surface (USS) on the balance and ambulation function of individuals with chronic spinal cord injury (SCI).

METHODS

Twenty-nine chronic patients with SCI were randomly divided into experiment group (N.=14) and control group (N.=15). The two groups received residual extremity muscle strengthening exercises (REMSE), body weight supported treadmill (BWSTT) training and CST five times per week for 12 weeks. Patients in control group were implemented CST on a stable support surface (SSS), but patients in experiment group on an unstable support surface (USS) created by sling in lying and physio-ball in sitting position. Gait and balance, static and dynamic, data were collected and analyzed by 3D Motion Analysis Software Version 1.0 (America) and Active Balancer EAB-100 (Sakai Iryo, Japan) respectively.

RESULTS

After the 12-week intervention, stride length, cadence, comfortable walking speed (P=0.025, 0.028, 0.009), and Romberg ratio of WPL, UPL, circumference area (CA), effective value area (EVA) (P=0.009, 0.009, 0.043, 0.049) and DCDX with eyes closed (P=0.036) of static balance showed significant differences between the two groups with the unstable group showing a better outcome.

CONCLUSIONS

Our pilot study was feasible to deliver. When combined with REMSE and BWSTT, CST on an USS surpasses SSS in terms of improving chronic SCI patients' ambulation and static balance function after a 12-week intervention.

Instrumented Version of the Modified Dynamic Gait Index in Patients With Neurologic Disorders

BACKGROUND

Gait instability is common in adults with neurologic disorders and the modified Dynamic Gait Index (mDGI) was recently introduced to assess dynamic balance. However, instrumental assessment is needed to provide quantitative measures.

OBJECTIVE

To develop and validate an instrumented version of the mDGI.

DESIGN

Cross-sectional study.

SETTING

Clinical setting.

PARTICIPANTS

Thirty adults with neurologic disorders (10 with multiple sclerosis, 10 with Parkinson disease, and 10 with stroke) and 20 healthy volunteers.

METHODS

Participants were assessed with the Timed Up and Go test (TUG) and with the mDGI. During the assessment of mDGI, data were collected by a single Inertial Measurement Unit (IMU) positioned on the sternum. Principal component analysis (PCA) was performed on the instrumented data extracting eight PC scores (ImPC) describing dynamic balance. The instrumented overall score (ImDGI) was then calculated as the sum of the mPCs. PCA revealed two components associated with stride features and regularity (ImDGI_Gait_Pattern) and trunk movements (ImDGI_Trunk_Sway). Spearman coefficients were calculated between mDGI and ImDGI, whereas Mann-Whitney (U) and Kruskal-Wallis (H) tests assessed differences between groups and neurologic conditions.

MAIN OUTCOME MEASUREMENTS

ImDGI.

RESULTS

ImDGI did not show ceiling effects, and good correlations were found between ImDGI and mDGI (r = .84), and TUG (r = .84) for people with neurologic disorders (P < .001). Significant differences among pathologies (H test₍₂₎ =12.5, P = .002) and between healthy participants and adults with neurologic disorders (U test = 47.0, P = .001) were found. ImDGI_Trunk_Sway discriminated between people using or not using walking aids and among the three pathologies (H₍₂₎ = 10.0, P = .007).

CONCLUSIONS

The ImDGI test seems to provide valid measures to objectively assess dynamic balance in neurologic conditions and possibly quantify balance deficits also in adults with neurologic disorders.

Feasibility of a targeted strengthening program to improve gait in people with multiple sclerosis: a brief report

This study aims to determine feasibility of strengthening muscles that are important contributors to gait for people with multiple sclerosis, yet are not routinely targeted in the literature. An 8-week strengthening intervention targeted ankle plantarflexion, hip abduction, and trunk muscles using a repeated-measures design. Outcomes included satisfaction, adherence, muscle strength, gait speed (timed 25-foot walk), gait endurance (6-min walk test), and self-reported gait-related participation (Multiple Sclerosis Walking Scale-12). Ten participants (Expanded Disability Status Scale: 3.5-5.5) completed the intervention. All participants were at least 'satisfied'; adherence was 87% (supervised sessions) and 75% (home sessions). All quantitative measures improved: muscle strength (23.1-47.6%, P<0.001-0.039), timed 25-foot walk (-13.4%, P<0.001), 6-min walk test (41.56 m, P=0.019), and Multiple Sclerosis Walking Scale-12 (-10.5, P=0.007). Strengthening of ankle plantarflexion, hip abduction, and trunk muscles was feasible and associated with improvements in gait performance.

Balance exercise facilitates everyday life for people with multiple sclerosis: A qualitative study

OBJECTIVES

The aim of this qualitative study was to describe the experience and perceived effects on everyday life for people with multiple sclerosis after participating in a balance exercise programme focusing on core stability, dual tasking, and sensory strategies (the CoDuSe programme).

METHODS

A qualitative approach was chosen, using face-to-face interviews analysed with content analysis. Twenty-seven people with multiple sclerosis (20 women, 7 men) who had participated in the CoDuSe programme were included. All could walk 20 m with or without walking aids but could not walk further than 200 m. The CoDuSe programme was given twice weekly during a 7-week period.

RESULTS

The analysis revealed five categories. Learning to activate the core muscles described how the participants gained knowledge of using their core muscles and transferred this core muscle activation into everyday life activities. Improved bodily confidence covered narratives of being more certain of the ability to control their bodies. Easier and safer activities showed how they could now perform activities in everyday life more safely and easily. Increased independence and participation involved the participants' improved ability and self-confidence to execute activities by themselves, as well as their increased participation in activities in daily living. Experiences of the balance exercise programme revealed that they found the programme novel and challenging. The overall theme was balance exercise facilitates everyday life.

CONCLUSION

Participating in the CoDuSe programme was perceived to facilitate everyday life for people with multiple sclerosis. Taking part in the balance exercise programme taught the participants how to activate and use the core muscles, which increased their bodily confidence. Having increased bodily confidence helped them to perform everyday life activities with more ease and safety, which increased their independence and participation. The participants described the CoDuSe programme as novel and challenging, yet feasible.

Contributions of Ankle, Knee, Hip, and Trunk Muscle Function to Gait Performance in People With Multiple Sclerosis: A Cross-Sectional Analysis

BACKGROUND

The relative importance of lower extremity and trunk muscle function to gait in people with multiple sclerosis (MS) is unknown.

OBJECTIVE

This study aimed to investigate the association of lower extremity and trunk muscle function with gait performance in people who have MS and mild-to-moderate disability.

DESIGN

This was a cross-sectional, observational study.

METHODS

Participants were people who had an Expanded Disability Status Scale score of ≤ 5.5. Eleven lower extremity and trunk muscles were assessed using handheld dynamometry or endurance tests. Gait performance was assessed with the Timed 25-Foot (7.62 m) Walk (T25FW) and 6-Minute Walk Test (6MWT). Regression analysis was used to quantify the association between gait outcomes and muscle variables.

RESULTS

Seventy-two participants with MS and a mean Expanded Disability Status Scale score of 3.5 (SD = 1.14) were enrolled. Adjusted for age and sex, the multivariate model including hip abduction, ankle plantar flexion, trunk flexion, and knee flexion explained 57% of the adjusted variance in the T25FW; hip abduction, ankle plantar flexion, and trunk flexion explained 61% of the adjusted variance in the 6MWT. The strongest predictors were ankle plantar flexion endurance for the T25FW and hip abduction strength for the 6MWT: a 1-SD increase in ankle plantar flexion (15.2 heel-raise repetitions) was associated with a 0.33-second reduction in the T25WT (95% CI = - 0.71 to - 0.14 seconds); a 1-SD increase in normalized hip abduction strength (0.14 kg/body mass index) was associated with a 54.4-m increase in the 6MWT (28.99 to 79.81 m).

LIMITATIONS

Different measurement scales for independent variables were included because the muscle function assessment used either force or endurance.

CONCLUSIONS

For the major muscles in the lower extremity and trunk, hip abduction, ankle plantar flexion, trunk flexion, and knee flexion were the strongest predictors of gait performance.

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.

Impact of Pilates Exercise in Multiple Sclerosis: A Randomized Controlled Trial

Background

Pilates is a series of exercises based on whole-body movement and may improve mobility in people with multiple sclerosis (MS). The purpose of this study was to determine the effect of Pilates on walking performance in people with MS.

Methods

30 individuals with MS who were not restricted to a wheelchair or scooter (Patient-Determined Disease Steps scale score <7) were randomized to receive Pilates (twice weekly) and massage therapy (once weekly) or once-weekly massage therapy only (control group). The Pilates was delivered in a group setting (five to ten participants per session). The primary outcome was change in walking performance (6-Minute Walk Test) after 12 weeks. Secondary outcomes included functional ability (Timed Up and Go test), balance (Fullerton Advanced Balance Scale), flexibility (sit and reach test), body composition (dual-energy X-ray absorptiometry), core endurance (plank-hold test), and muscle strength and voluntary activation (quadriceps). Intention-to-treat analysis was performed using a two-factor repeated-measures analysis of variance.

Results

Walking distance increased by a mean (SD) of 52.4 (40.2) m in the Pilates group versus 15.0 (34.1) m in the control group (group × time, P = .01). Mean (SD) time to complete the Timed Up and Go test decreased by 1.5 (2.8) seconds in the Pilates group versus an increase of 0.3 (0.9) seconds in the control group (group × time, P = .03). There were no other significant differences between groups over time.

Conclusions

Pilates improved walking performance and functional ability in persons with MS and is a viable exercise option to help manage the disease.

Feasibility and Efficacy of Mat Pilates on People with Mild-to-Moderate Parkinson's Disease: A Preliminary Study

This pilot study aimed at assessing the feasibility and efficacy of a Mat Pilates program in people with mild-to-moderate Parkinson's disease (PD). The participants carried out a Mat Pilates program twice a week for 12 weeks. The Senior Fitness Test battery and the 39-item PD Questionnaire were used to assess the effects of the program on the participants' fitness level and quality of life. A total of 16 patients with mild-to-moderate PD volunteered for and finished the study. The Mat Pilates program proved to be feasible. Adherence to the program was excellent, and no adverse effects were observed. The program had a positive effect on the participants' fitness levels, except for shoulder range of motion and dynamic balance, and on their quality of life. Assessments at follow-up indicated a regression in the improvements obtained by the end of the intervention, even though the sample still showed higher levels of fitness and quality of life than those tested at baseline. Mat Pilates is feasible and may be a beneficial rehabilitation strategy to improve fitness and quality of life in people with mild-to-moderate PD. Future randomized controlled trials might determine the extent of such benefits.

Effects on Balance and Walking with the CoDuSe Balance Exercise Program in People with Multiple Sclerosis: A Multicenter Randomized Controlled Trial

Background. Balance and walking impairments are frequent in people with multiple sclerosis (MS). Objective. The aim was to investigate the effects of a group-based balance exercise program targeting core stability, dual tasking, and sensory strategies (CoDuSe) on balance, postural sway, walking, perceived walking limitations, and balance confidence. Design. A single-blinded randomized multicenter trial. No intervention was given to controls. Participants. People with MS able to walk 100 meters but unable to maintain tandem stance ≥30 seconds. Eighty-seven participants were randomized to intervention or control. Intervention. The 60-minute CoDuSe group program, twice weekly for seven weeks, supervised by physical therapists. Measurements. Primary outcome was dynamic balance (Berg Balance Scale (BBS)). Secondary outcomes were postural sway, walking (Timed-Up and Go test; Functional Gait Assessment (FGA)), MS Walking Scale, and Activities-specific Balance Confidence (ABC) Scale. Assessments were performed before and after (week 8) the intervention. Results. 73 participants fulfilled the study. There were significant differences between the intervention and the control groups in change in the BBS and in the secondary measures: postural sway with eyes open, FGA, MS Walking Scale, and ABC scale in favor of the intervention. Conclusions. The seven-week CoDuSe program improved dynamic balance more than no intervention.

CoDuSe group exercise programme improves balance and reduces falls in people with multiple sclerosis: A multi-centre, randomized, controlled pilot study

Background:

Imbalance leading to falls is common in people with multiple sclerosis (PwMS).

Objective:

To evaluate the effects of a balance group exercise programme (CoDuSe) on balance and walking in PwMS (Expanded Disability Status Scale, 4.0–7.5).

Methods:

A multi-centre, randomized, controlled single-blinded pilot study with random allocation to early or late start of exercise, with the latter group serving as control group for the physical function measures. In total, 14 supervised 60-minute exercise sessions were delivered over 7 weeks. Pretest–posttest analyses were conducted for self-reported near falls and falls in the group starting late. Primary outcome was Berg Balance Scale (BBS). A total of 51 participants were initially enrolled; three were lost to follow-up.

Results:

Post-intervention, the exercise group showed statistically significant improvement (p = 0.015) in BBS and borderline significant improvement in MS Walking Scale (p = 0.051), both with large effect sizes (3.66; −2.89). No other significant differences were found between groups. In the group starting late, numbers of falls and near falls were statistically significantly reduced after exercise compared to before (p < 0.001; p < 0.004).

Conclusion:

This pilot study suggests that the CoDuSe exercise improved balance and reduced perceived walking limitations, compared to no exercise. The intervention reduced falls and near falls frequency.
