Reducing falls and improving mobility in multiple sclerosis

Preventing falls in multiple sclerosis: a qualitative study on user requirements for a self-management programme

PURPOSE

To explore perspectives of ambulatory and non-ambulatory people with MS (PwMS) and health care professionals (HCPs) on falls and falls management to gain a deeper understanding of how a self-management programme can be designed to fit the needs of end users.

MATERIALS AND METHODS

Twelve PwMS and seven HCPs participated in three four-hour workshops based on Design Thinking. Collected data were field notes and digital post-it notes gathered at the workshops. Data were analyzed using qualitative content analysis with an inductive approach.

RESULTS

Two main categories, "Managing the complexity of fall-risk behaviour" and "Embracing diversity to establish group engagement", comprising a total of seven categories were constructed from the analysis. The first main category reflects the challenges PwMS face in managing fall risk in their daily lives, and the support needed to address these challenges. The second main category highlights how engaging in peer learning activities can fulfil individual needs and improve learning outcomes for PwMS.

CONCLUSION

A self-management fall prevention programme that is relevant to PwMS regardless of ambulation level should include the development of self-tailored behavioural strategies to prevent falls along with interactive learning activities with other PwMS.

Effects of backward walking training on balance, gait, and functional mobility in people with multiple sclerosis: A randomized controlled study

BACKGROUND

Backward walking training (BWT) can have a positive effect on balance, gait, and functional mobility in neurological diseases; however, the effectiveness of BWT has not been examined in multiple sclerosis (MS). Therefore, the study aimed to investigate the effects of BWT on balance, gait, and functional mobility in people with MS (PwMS).

METHOD

Nineteen PwMS were randomly allocated to either the experimental group (n=10) and the control group (n=9). The experimental group received BWT in addition to conventional walking training (CWT) while the control group only received CWT. Both groups performed training three times a week for 8 weeks. Participants were assessed with the Berg Balance Scale (BBS), four square step test (FSST), activities-specific balance confidence scale (ABC), timed 25-foot walk test (T25FW), dynamic gait index (DGI), 3-meter backward walk test (3MBWT), Multiple Sclerosis Walking Scale-12 (MSWS-12), and timed up and go test (TUG) before and after training.

RESULTS

After training, both groups showed significant improvements on the T25FW, and TUG (p<0.05) while only the experimental group showed significant improvements on the BBS, FSST, ABC, DGI, 3MBWT, and MSWS-12 (p<0.05). The experimental group significantly improved more than the control group in all outcomes (p<0.05) except for the T25FW (p=0.202).

CONCLUSION

BWT in addition to CWT is an effective way to improve balance, gait, and functional mobility for PwMS. These results suggest that BWT may be a potentially useful treatment approach when added to CWT in the rehabilitation of MS.

Fall Assessment and Monitoring in People With Multiple Sclerosis: A Practical Evidence-Based Review for Clinicians

Purpose of Review

Falls occur in more than half of all people with multiple sclerosis (MS) but tend to be underdiagnosed and underreported in clinical encounters. This narrative review aims to summarize evidence-based approaches for evaluating fall risk and proven treatment strategies to reduce falling in people with MS to improve care for people with MS and to enhance interprofessional care coordination between treating neurologic and physical therapy (PT) teams.

Recent Findings

Screening not just for falls but for near-falls as well because fear of falling can improve fall assessment and identify patients who may benefit from fall prevention interventions. A number of barriers, including time constraints during visits and the fallacy that falling is inevitable in MS, can limit clinician awareness about patient falls and delay timely referral to PT. Consultation with physical therapists for individualized fall prevention treatment can reduce risk of falling. Interventional studies have also shown that PT-guided exercise programs improve balance confidence in people with MS. However, people with MS are often under-referred to PT by treating clinicians.

Summary

A clinical approach is provided to summarize practical, accessible, evidence-based, low-burden measurements and interventions likely to improve ascertainment of patients at risk of falling and optimize timely PT referral and treatment.

Cognitive Crescendo: How Music Shapes the Brain's Structure and Function

Music is a complex phenomenon with multiple brain areas and neural connections being implicated. Centuries ago, music was discovered as an efficient modality for psychological status enrichment and even for the treatment of multiple pathologies. Modern research investigations give a new avenue for music perception and the understanding of the underlying neurological mechanisms, using neuroimaging, especially magnetic resonance imaging. Multiple brain areas were depicted in the last decades as being of high value for music processing, and further analyses in the neuropsychology field uncover the implications in emotional and cognitive activities. Music listening improves cognitive functions such as memory, attention span, and behavioral augmentation. In rehabilitation, music-based therapies have a high rate of success for the treatment of depression and anxiety and even in neurological disorders such as regaining the body integrity after a stroke episode. Our review focused on the neurological and psychological implications of music, as well as presenting the significant clinical relevance of therapies using music.

Self-management of falls in people with multiple sclerosis: A scoping review

OBJECTIVE

Falls are common in people with multiple sclerosis. There is rising interest in how the multifactorial and chronic nature of fall risk among people with multiple sclerosis can be addressed through self-management. Thus, the aims were to investigate the extent and the scope of publications on self-management of falls in people with multiple sclerosis, and to identify how the concept of self-management was defined and used.

DATA SOURCES

A systematic literature search in Medline, Cochrane, Web of Science and PsycInfo was conducted to identify publications until July 2022.

REVIEW METHODS

Published methodological guidance was followed. Articles targeting: (1) people with multiple sclerosis, (2) falls, and (3) self-management were selected. Of 1656 records, 203 publications were assessed for eligibility, of which 173 did not meet the inclusion criteria, and 16 publications did not contain empirical data. The type of publication, study focus, and study design was extracted. If applicable, key findings, self-management tasks and skills, and the definition of self-management were extracted.

RESULTS

Fourteen original articles met all inclusion criteria. Ten articles represented six different fall prevention interventions. Three publications were randomized controlled trials. Self-management content was variable and not comprehensive in nature. None of the 14 publications included a self-management definition.

CONCLUSION

The limited number of original articles and the even fewer intervention studies show that the research on self-management of falls in people with multiple sclerosis is in its infancy. To progress in the research area of self-management of falls, a more robust, consensus-based description of self-management frameworks and activities is needed.

Online self-management fall prevention intervention for people with multiple sclerosis: a feasibility study protocol of a parallel group randomised trial

INTRODUCTION

Falls among people with multiple sclerosis (PwMS) are common and associated with injuries, fear of falling and low health-related quality of life. Considerations of behavioural, environmental, psychological and physical influences (including ambulation status) are needed to meet fall prevention needs for PwMS. Thus, using a codesign process involving key stakeholders a novel online self-management fall prevention intervention was created specifically for ambulatory and non-ambulatory PwMS. The feasibility, acceptability, fidelity and outcome of this complex intervention will be explored. Findings will inform a future full-scale randomised controlled trial.

METHODS AND ANALYSIS

A mixed-method design will be used. Forty-eight PwMS, stratified for ambulation level, will be randomised to control (n=24) or intervention (n=24). Both groups will receive a brochure about fall risk factors and fall prevention. The intervention is group-based (eight PwMS in each group); will be delivered online; and involve six, 2-hour weekly sessions and a booster session 8 weeks after the sixth session. Each intervention group will be led by a trained facilitator. Data collection will be performed at baseline, and after seven and 18 weeks. Outcome measures will capture data on fall prevention behaviours, fear of falling, falls self-efficacy, social and everyday activities, perceived impact of MS and number of falls. Feasibility of recruitment process, data collection procedures, outcome measures, and delivery, and intervention acceptability, fidelity and outcomes will be evaluated. Both quantitative and qualitative methods will be used.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the Swedish Ethical Review Authority (registration number 2021-04817). Results will be disseminated in peer-review journals, at conferences, research meetings, in social media and through the patient organisation Neuro Sweden.

TRIAL REGISTRATION NUMBER

NCT04317716.

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.

Effectiveness of interventions to prevent falls for people with multiple sclerosis, Parkinson's disease and stroke: an umbrella review

BACKGROUND

The implementation of condition-specific falls prevention interventions is proving challenging due to lack of critical mass and resources. Given the similarities in falls risk factors across stroke, Parkinson's Disease (PD) and Multiple Sclerosis (MS), the development of an intervention designed for groups comprising of people with these three neurological conditions may provide a pragmatic solution to these challenges. The aims of this umbrella review were to investigate the effectiveness of falls prevention interventions in MS, PD and stroke, and to identify the commonalities and differences between effective interventions for each condition to inform the development of an intervention for mixed neurological groups.

METHODS

A systematic literature search was conducted using 15 electronic databases, grey literature searches and hand-screening of reference lists. Systematic reviews of studies investigating the effects of falls prevention interventions in MS, PD and stroke were included. Methodological quality of reviews was assessed using the A MeaSurement Tool to Assess Systematic Reviews 2. A matrix of evidence table was used to assess the degree of overlap. The Grading of Recommendations Assessments, Development and Evaluation framework was used to rate the quality of evidence. Findings were presented through narrative synthesis and a summary of evidence table.

RESULTS

Eighteen reviews were included; three investigating effectiveness of falls prevention interventions in MS, 11 in PD, three in stroke, and one in both PD and stroke. Exercise-based interventions were the most commonly investigated for all three conditions, but differences were identified in the content and delivery of these interventions. Low to moderate quality evidence was found for the effectiveness of exercise-based interventions at reducing falls in PD. Best available evidence suggests that exercise is effective at reducing falls in stroke but no evidence of effect was identified in MS.

CONCLUSIONS

The findings suggest that exercise-based interventions are effective at reducing falls in PD, however, the evidence for MS and stroke is less conclusive. A strong theoretical rationale remains for the use of exercise-based interventions to address modifiable physiological falls risk factors for people with MS, PD and stroke, supporting the feasibility of a mixed-diagnosis intervention. Given the high overlap and low methodological quality of primary studies, the focus should be on the development of high-quality trials investigating the effectiveness of falls prevention interventions, rather than the publication of further systematic reviews.

Effective rehabilitation interventions and participation among people with multiple sclerosis: an overview of reviews

BACKGROUND

Multiple sclerosis (MS) is the most common cause of non-traumatic disability in people aged 10 to 65 years. Evidence exists for the effectiveness of multidisciplinary rehabilitation and exercise. However, the effectiveness of other rehabilitation approaches in MS needs further evaluation.

OBJECTIVE

We aimed to systematically synthesize and evaluate knowledge on effectiveness of rehabilitation interventions and determinants for participation among people with MS (pwMS) to inform clinical guidelines on rehabilitation.

METHODS

Joanna Briggs Institute methodology was used. PubMed, Embase, CINAHL, PsycINFO and Web of Science were searched for reviews, systematic reviews, meta-analyses, and meta-syntheses published during 2009-2019. All types of rehabilitation interventions provided to pwMS at any time and in all settings were eligible. Two reviewers independently screened and extracted data. The most recently published reviews on mixed and specific modalities were included. The findings were reported in a narrative summary and a mixed-methods analysis.

RESULTS

Among 108 eligible reviews, 6 qualitative or mixed-methods reviews and 66 quantitative reviews were included (total pwMS >90,000). This overview provides solid evidence for the effectiveness of a spectrum of modalities. Among the modalities, there was strong evidence for the effectiveness of multidisciplinary, cognitive and exercise approaches, physiotherapy, and occupational therapy, including full body training on functioning, and participation outcomes. Employment significantly affected quality of life; thus, vocational rehabilitation should be initiated early. Healthcare professionals should identify personal factors including relations and coping, and the rehabilitation process should involve partners or close family.

CONCLUSIONS

The mixed-methods analysis revealed insufficient consensus between the perspectives of pwMS on their rehabilitation and reported effects, indicating that further research should target the experiences of pwMS. Furthermore, rehabilitation should be patient-centred, focus on the complexity of needs, and be organised and performed by an experienced multidisciplinary team. Evidence-based rehabilitation should be initiated early after pwMS are diagnosed and follow international guidelines. Database registration. PROSPERO ID (CRD42020152422).

Falls in People with Multiple Sclerosis: Risk Identification, Intervention, and Future Directions

Falls are highly prevalent in people with multiple sclerosis (MS) and result in a range of negative consequences, such as injury, activity curtailment, reduced quality of life, and increased need for care and time off work. This narrative review aims to summarize key literature and to discuss future work needed in the area of fall prevention for people with MS. The incidence of falls in people with MS is estimated to be more than 50%, similar to that in adults older than 80 years. The consequences of falls are considerable because rate of injury is high, and fear of falling and low self-efficacy are significant problems that lead to activity curtailment. A wide range of physiological, personal, and environmental factors have been highlighted as potential risk factors and predictors of falls. Falls are individual and multifactorial, and, hence, approaches to interventions will likely need to adopt a multifactorial approach. However, the literature to date has largely focused on exercise-based interventions, with newer, more comprehensive interventions that use both education and exercise showing promising results. Several gaps in knowledge of falls in MS remain, in particular the lack of standardized definitions and outcome measures, to enable data pooling and comparison. Moving forward, the involvement of people with MS in the design and evaluation of programs is essential, as are approaches to intervention development that consider implementation from the outset.

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.

Fall definitions, faller classifications and outcomes used in falls research among people with multiple sclerosis: a systematic review

Purpose: To identify the definitions of a fall, faller classifications and outcomes used in prospectively-recorded falls research among people with Multiple Sclerosis (MS).Methods: A systematic review of peer-reviewed journal articles was conducted using electronic databases. Relevant data were extracted by one reviewer and verified by a second independent reviewer.Results: Twenty-six papers met the inclusion criteria. A relative degree of heterogeneity existed amongst studies for the outcomes of interest to this review. Thirteen different fall definitions were identified. Fourteen different falls outcomes were used across the included studies, with six of these reported by only one study each. Data regarding injurious falls were presented by only eight papers. The majority (n = 17) of papers classified individuals as a faller if they fell at least once.Conclusions: This review highlights the large variation in fall definitions, faller classifications and outcomes used in this research field. This hinders cross-comparison and pooling of data, thereby preventing researchers and clinicians from drawing conclusive findings from existing literature. The creation of an international standard for the definition of a fall, faller classification and falls outcomes would allow for transparent and coordinated falls research for people with MS, facilitating progression in this research field.Implications for rehabilitationFalls are a common occurrence among people with Multiple Sclerosis (MS) resulting in numerous negative consequences.There is large heterogeneity in the definitions, methods and outcomes used in falls research for people with MS.This lack of standardisation prevents the accurate cross-comparison and pooling of data, impeding the identification of falls risk factors and effective falls prevention interventions for people with MS.Consequently, clinicians should interpret the outcomes of falls research for people with MS with caution, particularly when comparing studies regarding falls risk assessments and falls prevention interventions for use in clinical practice.

Development of the Better Balance Program for People with Multiple Sclerosis: A Complex Fall-Prevention Intervention

Background

Approximately 56% of people with multiple sclerosis (MS) will fall in any 3-month period, with the potential for physical, psychological, and social consequences. Fall-prevention research for people with MS is in its infancy, with a timely need to develop theory-based interventions that reflect the complexity of falls. The clear articulation of the development of any complex intervention is paramount to its future evaluation, usability, and effectiveness. Our aim was to describe how the development of Better Balance, a complex multicomponent fall-prevention intervention for people with MS, was guided by the Medical Research Council framework for the development of complex interventions.

Methods

Sources of information included existing literature, original research, clinician interviews, and views of people with MS. These sources were synthesized and refined through an iterative process of intervention development involving researchers, clinicians, and people with MS.

Results

The resulting intervention is outlined through a variety of key tasks supplementing the original Medical Research Council framework. Use of this framework resulted in a theoretically based and user-informed complex intervention designed to address the physiological, personal, and behavioral risk factors associated with falls in people with MS.

Conclusions

The articulation of the systematic process used to develop Better Balance will inform the future evaluation and usability of the intervention.

Exercise Interventions for Individuals With Neurological Disorders: A Systematic Review of Systematic Reviews

Fall prevention requires a multifaceted approach that should include individual risk assessment and intervention strategies. Exercise interventions may mitigate most risk factors for falls (eg, balance impairment, gait impairment, and muscle weakness). Numerous systematic reviews or meta-analyses have assessed the effectiveness of exercise interventions among people with various types of neurological disorders; however, the evidence obtained has not been synthesized into an overview. Therefore, the present systematic review assessed systematic reviews of exercise intervention for fall prevention among people with neurological disorders. The research sources were the Cochrane Database of Systematic Reviews, PubMed, and Embase. Eligible studies were selected, and data were extracted independently by two reviewers. A total of 15 studies (six systematic reviews and nine meta-analyses) were included. These systematic reviews examined in this study have demonstrated that exercise interventions reduced the number, frequency, and rate of falls among people with neurological disorders, including cognitive impairment, dementia, and Parkinson disease. Furthermore, the current study presented insufficient evidence regarding the effectiveness of exercise interventions for fall prevention among people with stroke, multiple sclerosis, and diabetes mellitus with polyneuropathy. Therefore, additional investigations are necessary to evaluate the effectiveness of exercise for fall prevention among people with multiple sclerosis, stroke, and diabetes mellitus with polyneuropathy.

A Controlled Clinical Trial on the Effects of Exercise on Cognition and Mobility in Adults With Multiple Sclerosis

OBJECTIVE

The aim of the study was to investigate the effects of a 6-mo exercise program on cognition and mobility in participants with multiple sclerosis.

DESIGN

This is a prospective, single-blind, controlled clinical trial.

SETTING

A community rehabilitation program within a large metropolitan health service.

PARTICIPANTS

Twenty-eight patients with multiple sclerosis were referred for outpatient rehabilitation.

INTERVENTIONS

Participants were allocated to one of two groups and undertook a cognitive-motor exercise program or monitoring (control group).

MAIN OUTCOME MEASURES

Cognition and mobility were the main outcome measures. Cognition was evaluated using the Mini-Mental State Examination and the Frontal Assessment Battery. Mobility was assessed with the Timed Get Up and Go test, applied with and without dual task distractors.

RESULTS

The findings showed benefits provided by exercise on cognition and mobility. Differently, participants of the control group did not have significant changes in cognition scores after 6 mos of follow-up and had a worse performance in mobility tests.

CONCLUSION

Six months of exercise provided benefits to cognition and mobility in adults with multiple sclerosis. This trial was registered prospectively with the Brazilian Clinical Trials Register, ID: RBR-9gh4km (http://www.ensaiosclinicos.gov.br/rg/?q=RBR-9gh4km).

ADSTEP: Preliminary Investigation of a Multicomponent Walking Aid Program in People With Multiple Sclerosis

OBJECTIVE

To evaluate the effect of the Assistive Device Selection, Training and Education Program (ADSTEP) on falls and walking and sitting activity in people with multiple sclerosis (PwMS).

DESIGN

Randomized controlled trial.

SETTING

Veterans affairs medical center.

PARTICIPANTS

PwMS (N=40) using a walking aid at baseline who had fallen in the previous year.

INTERVENTIONS

Participants were randomly assigned to ADSTEP or control. ADSTEP had 6 weekly, 40-minute, 1-on-1 sessions with a physical therapist, starting with walking aid selection and fitting, followed by task-oriented progressive gait training. Control was usual medical care with the option of ADSTEP after the study.

MAIN OUTCOME MEASURES

The following were assessed at baseline, intervention completion, and 3 months later: falls, timed Up and Go, timed 25-foot walk, 2-minute walk, Four Square Step Test, International Physical Activity Questionnaire, Quebec User Evaluation of Satisfaction with Assistive Technologies, Multiple Sclerosis Walking Scale-12, Activities-Specific Balance Confidence Scale, and Multiple Sclerosis Impact Scale-29. Effect on these outcomes was estimated by a 2-by-2 repeated measures general linear model.

RESULTS

Fewer ADSTEP than control participants fell (χ²=3.96, P<.05. number needed to treat =3.3). Time spent sitting changed significantly differently with ADSTEP than with control from baseline to intervention completion (F=11.16, P=.002. ADSTEP: reduced 87.00±194.89min/d; control: increased 103.50±142.21min/d; d=0.88) and to 3-month follow-up (F=9.25, P=.004. ADSTEP: reduced 75.79±171.57min/d; control: increased 84.50±149.23min/d; d=0.79). ADSTEP yielded a moderate effect on time spent walking compared to control at 3-month follow-up (P>.05. ADSTEP 117.53±148.40min/d; control 46.43±58.55min/d; d=0.63).

CONCLUSIONS

ADSTEP prevents falls, reduces sitting, and may increase walking in PwMS.

Therapies for mobility disability in persons with multiple sclerosis

INTRODUCTION

Mobility disability is one of the most widespread and impactful consequences of multiple sclerosis (MS). Disease modifying drugs (DMDs) may delay the progression of disability over time; however, there is minimal evidence supporting the efficacy of DMDs for reversing mobility disability or restoring ambulatory function in persons with MS. Areas covered: This review outlines symptomatic pharmacologic and non-pharmacologic therapeutic approaches that target mobility disability with the goal of restoring and improving walking function. First, the efficacy of dalfampridine, currently the only Food and Drug Administration approved symptomatic pharmacologic agent that improves walking in persons with MS is described. Next, a review of the efficacy of non-pharmacologic therapies for improving walking, including exercise training, physical therapy, and gait training is given. Last, guidance on future research on mobility in MS is provided by emphasizing the importance of combinatory treatment approaches that include multiple intervention modalities, as the best treatment plan likely involves a comprehensive, multidisciplinary approach. Expert commentary: There has been an increased effort to develop symptom-specific treatments in MS that directly target mobility disability; however, more research is needed to determine the efficacy of these rehabilitative strategies alone and together for improving walking in persons with MS.

Effects of cognitive versus motor dual-task on spatiotemporal gait parameters in healthy controls and multiple sclerosis patients with and without fall history

BACKGROUND

The purpose of the current study was to compare the effects of cognitive or motor tasks on gait performance between healthy controls and multiple sclerosis (MS) patients with and without fall history.

METHODS

The investigation included MS patients with fall history (n = 25) and without fall history (n = 25) and matched healthy controls (n = 25). Participants walked at their preferred speed on a motorized treadmill under three walking conditions in a randomized order: walking only, walking while performing a concurrent cognitive task (counting backward aloud by 3s), and walking while performing a concurrent motor task (carrying a tray with glasses).

RESULTS

The findings showed that in patients with MS, regardless of fall history, spatiotemporal gait parameters were different compared to healthy controls. In contrast to average gait parameters, variability in stride length and stride time could discriminate between MS fallers and non-fallers. Simultaneous performance of cognitive task and walking resulted in higher dual-task costs (DTC) in gait performance compared to the motor dual-task. However, the pattern of change was not different among the three groups. All participants responded to the cognitive task challenges by increasing stride length and decreasing cadence and stride length variability while maintaining cognitive task performance.

CONCLUSIONS

The findings may reflect successful adaptation of locomotor system to preserve cognitive task performance under cognitive dual-task condition. Future studies should examine more complex concurrent cognitive and motor tasks to better understand the dual-task-related gait changes and their contribution to falls in patients with MS.

Fall prevalence in people with multiple sclerosis who use wheelchairs and scooters

Falls are a serious health concern for persons with multiple sclerosis (PwMS) who use wheelchairs or scooters as their primary mode of mobility. Unfortunately, little is known about the fall prevalence and characteristics of this large segment of the multiple sclerosis (MS) community. The purpose of this study is to determine the prevalence and circumstances of falls in wheelchair and scooter users living with MS. Forty-four PwMS were recruited from research and medical centers in the United States and Asia. Participants completed a survey focusing on prevalence of falls, frequency of injurious falls, circumstances of the fall, and various quality of life indicators. A total of 44 individuals (32 females/11 males/1 not reported) aged 27 to 82 years (mean = 58 yrs) completed the survey. Seventy-five percent (n = 33) reported falling at least once in 6 months and 48% (n = 12) of those that fell sustained an injury. The majority (87.5%) of the falls occurred inside the home. Most individuals (76.7%; n = 33) reported concerns about falling and 65.9% (n = 29) limited their activities because of their concern of falling. Falls are prevalent in wheelchair and scooter users with MS. The observations highlight the need for interventions targeting this segment of the MS community.

An exploration of fall-related, psychosocial variables in people with multiple sclerosis who have fallen

Introduction

Psychosocial contributors to fall risk for people with multiple sclerosis are often overlooked in falls prevention practice. This study explored several fall-related, psychosocial variables and their association with falls self-efficacy in a sample of people with multiple sclerosis reporting a fall.

Method

A cross-sectional, structured telephone survey was employed. The survey explored socio-demographics, multiple sclerosis characteristics, and fall-related psychosocial variables. Multiple linear regression was employed to investigate associations with Falls Efficacy Scale – International scores.

Results

The mean Falls Efficacy Scale – International score for 140 participants was 38.14(SD = 10.16), and the mean Falls Control Scale score was 5.38(SD = 2.22). Fear of falling was expressed by 129 (92%) participants, with 111 (79%) reporting associated activity curtailment. A regression model including six predictors explained 47% of the variance in the Falls Efficacy Scale – International scores. Results of the multiple linear regression showed that fear of falling, associated activity curtailment, balance interference, falls control, and health status were associated with falls self-efficacy.

Conclusion

Fear of falling and associated activity curtailment, low falls self-efficacy, and compromised falls control are common among people with multiple sclerosis who have fallen. These fall-related psychosocial variables are distinct and each warrants attention during assessment. Findings suggest that falls self-efficacy among people with multiple sclerosis who have fallen is a complex construct associated with physical and psychosocial factors.

The effect of exercise training in adults with multiple sclerosis with severe mobility disability: A systematic review and future research directions

INTRODUCTION

There is evidence for the benefits of exercise training in persons with multiple sclerosis (MS). However, these benefits have primarily been established in individuals with mild-to-moderate disability (i.e., Expanded Disability Status Scale [EDSS] scores 1.0-5.5), rather than among those with significant mobility impairment. Further, the approaches to exercise training that have been effective in persons with mild-to-moderate MS disability may not be physically accessible for individuals with mobility limitations. Therefore, there is a demand for an evidence-base on the benefits of physically accessible exercise training approaches for managing disability in people with MS with mobility impairment.

OBJECTIVE

To conduct a systematic review of the current literature pertaining to exercise training in individuals with multiple sclerosis (MS) with severe mobility disability.

METHODS

Four electronic databases (PubMed, EMBASE, OvidMEDLINE, and PsychINFO) were searched for relevant articles published up until October 2016. The review focused on English-language studies that examined the effect of exercise training in people with MS with severe mobility disability, characterized as the need for assistance in ambulation or EDSS score ≥ 6.0. The inclusion criteria involved full-text articles that: (i) included participants with a diagnosis of MS; (ii) included primarily participants with a reported EDSS score ≥ 6.0 and/or definitively described disability consistent with this level of neurological impairment; and (iii) implemented a prospective, structured exercise intervention. Data were analyzed using a descriptive approach and summarized by exercise training modality (conventional or adapted exercise training), and by outcome (disability, physical fitness, physical function, and symptoms and participation).

RESULTS

Initially, 1164 articles were identified and after removal of duplicates, 530 articles remained. In total, 512 articles did not meet the inclusion criteria. 19 articles were included in the final review. Five studies examined conventional exercise training (aerobic and resistance training), and thirteen studies examined adapted exercise modalities including body-weight support treadmill training (BWSTT), total-body recumbent stepper training (TBRST), and electrical stimulation cycling (ESAC). Outcomes related to mobility, fatigue, and quality of life (QOL) were most frequently reported. Two of five studies examining conventional resistance exercise training reported significant improvements in physical fitness, physical function, and/or symptomatic and participatory outcomes. Nine of 13 studies examining adapted exercise training reported significant improvements in disability, physical fitness, physical function, and/or symptomatic and participatory outcomes.

CONCLUSIONS

There is limited, but promising evidence for the benefits of exercise training in persons with MS with severe mobility disability. Considering the lack of effective therapeutic strategies for managing long-term disability accumulation, exercise training could be considered as an alternative approach. Further research is necessary to optimize the prescription and efficacy of exercise training for adults with MS with severe mobility disability.

Mobility measures differentiate falls risk status in persons with multiple sclerosis: An exploratory study

BACKGROUND

Falls are of great concern among persons with multiple sclerosis (MS).

OBJECTIVE

To examine differences in metrics of mobility, postural control, and cognition in persons with MS with distinct fall risk status; and to investigate predictors of fall risk group membership using discriminant analysis.

METHODS

Forty-seven persons with MS completed the Activities-Balance Confidence (ABC) Scale and underwent a battery of assessments of mobility, balance, and cognition. Participants further wore an accelerometer for 7 days as an assessment of steps/day. Participants were allocated into fall risk groups based on ABC scale scores (increased fall risk (IFR); and normal fall risk (NFR)). We examined univariate differences between groups using ANOVA, and discriminant function analysis (DFA) identified the significant multivariate predictors of FR status.

RESULTS

After controlling for disability level, the IFR group had significantly (p < 0.05) worse scores on measures of mobility (i.e., MSWS-12, 6 MW, and steps/day) compared to the NFR group. DFA identified MSWS-12 and 6 MW scores as significant (p < 0.05) predictors of fall risk group membership. Those two variables collectively explained 55% of variance in fall risk grouping.

CONCLUSIONS

The findings suggest that mobility should be the focus of rehabilitation programs in persons with MS, especially for those at IFR.
