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.

Process evaluation findings of a fall prevention and management program for wheelchair and scooter users with multiple sclerosis

Objective

To describe process evaluation findings of a clinical trial to evaluate the Individualized Reduction of Falls (iROLL) program, a 6-session, group-based intervention designed to reduce fall incidence among people living with multiple sclerosis (MS) who use a wheelchair or scooter full-time.

Methods

A mixed-methods process evaluation focusing on implementation and mechanisms of impact (MOI) was conducted. Both iROLL participants and trainers (licensed occupational or physical therapists) provided input.

Results

Seventeen iROLL participants and nine trainers participated. The overall session attendance rate was 93%. Content and logistics fidelity were 95% and 90%, respectively and average overall participant satisfaction rating was 4.7/5.0. Five MOI themes emerged: group dynamic, comprehensive nature of the program, strong program development, role of a skilled interventionist, and motivated participants. Recruitment challenged program reach.

Conclusion

iROLL is acceptable to the target audience, can be delivered with high fidelity and has diverse and interacting mechanisms of impact operating. Remote delivery may improve reach.

Innovation

Effective iROLL delivery requires trainers with strong group management skills who can also individualize material while maintaining program fidelity. Comprehensive training and on-going support of the occupational and physical therapists delivering iROLL bolsters program effectiveness. Program access may improve with online delivery.

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.

Prediction of future falls among full-time wheelchair and scooter users with multiple sclerosis: A prospective study

BACKGROUND

Seventy-five percent (75%) of full-time wheelchair or scooter users with multiple sclerosis (MS) experience at least one fall in a period of 6 months. Falls are detrimental for the independence, quality of life, and community participation. No previous prospective study has evaluated fall risk factors in this segment of MS community.

OBJECTIVE

To develop a multivariable falls risk prediction model for people with MS (PwMS) who use a wheelchair or scooter full-time.

METHODS

This prospective cohort study is a secondary data analysis that recruited PwMS from the community across the US. Forty-eight adults with MS who use a wheelchair or scooter as their main form of mobility were included. Dependent variable was fall incidence over 3-month recorded through diaries. Dependent variable was categorized as fallers (≥ 1 fall) and non-fallers (0 fall). Predictors were demographics, history of falls in the past 6 months, measures of fear of falling, Spinal Cord Injury- Falls Concern Scale, California Verbal Learning Test II, and Multiple Sclerosis Quality of Life- mental health. Multivariable logistic regression analyses were conducted to identity predictors of future falls.

RESULTS

In total, 63 falls (range 0 - 8) were reported over the 3-month period from a total of 26 fallers (54%). Multivariate logistic regression analyses indicated that the risk factor with the best predictive ability of future falls included history of falls in the past 6 months (sensitivity 77%, specificity 54%, and area under the receiving operating curve statistic = 0.76, 95% CI 0.62 to 0.89).

CONCLUSION

Findings highlight the importance of asking full-time wheelchair and scooter users with MS if they have fallen in the past 6 months to quickly identify those who are at increased fall risk and in need of follow up assessment and intervention to identify and address modifiable risk factors. More attention to fall risks among full-time wheelchair or scooter users with MS is suggested to increase the understanding among clinicians and researchers of modifiable risk factors.

Risk factors associated with falls and fall-related injuries among wheelchair users with spinal cord injury

•

Shorter time since injury and higher mobility levels as well as poor physical health are associated with higher risk of falls and fall-related injuries, respectively in wheelchair users with spinal cord injury.

•

The findings indicate good discriminant ability and clinical utility of the factors presented to identify wheelchair users who are at risk of falls and fall-related injuries.

Objective

To identify risk factors for falls and fall-related injuries for wheelchair users with spinal cord injury (SCI).

Design

Cross-sectional study.

Setting

Community setting.

Participants

Fifty-nine community dwelling wheelchair users (N=59), 47.5% male, median age of 52.5 years (IQR, 21 years) with chronic SCI, median time since injury of 16.6 years (IQR, 27.3 years).

Interventions

No intervention.

Main Outcome Measures

Outcomes were incidence of falls and fall-related injuries. Participants reported on falls and fall-related injuries experienced in the previous 6 months. Independent variables were self-reported and performance-based measures. Self-reported measures included demographics, characteristics of SCI, fear of falling, psychological measures, functional independence, wheelchair skills, environmental barriers, quality of life, and community participation. Performance-based measures included transfer quality and sitting balance assessments. Logistic regression analyses were conducted to identify factors influencing falls and fall-related injuries.

Results

In total, 152 falls and 30 fall-related injuries were reported from a total of 37 fallers. After logistic regression analysis, the model with the greatest levels of clinical utility and discriminative ability for falls (sensitivity 81%; specificity 55%; area under the receiving operating characteristic curve [AUC] statistics=0.73; 95% CI, 0.60-0.86) included the variables of shorter time since SCI, high mobility level, and having received education on fall prevention. The model for fall-related injuries (sensitivity 79%; specificity 75%; AUC statistics=0.77; 95% CI, 0.59-0.96) included the variables of older male individual, lower physical health score, and having received education on fall prevention.

Conclusions

The regression models presented may be used to identify wheelchair users with SCI at greater risk of falls and fall-related injuries. The findings may help to refer those in need to tailored fall and fall-related injury prevention programs. The findings presented in this study were based on a relatively small sample convenience; therefore, further prospective studies with a larger sample size are warranted.

Smartphone applications to assess gait and postural control in people with multiple sclerosis: A systematic review

BACKGROUND

Methods to effectively assess gait and balance impairments are necessary to guide interventions among people with Multiple Sclerosis (PwMS). Smartphone-based evaluations are becoming popular due to the ubiquitous use of smartphones in society.

OBJECTIVE

To determine the current state of smartphone applications that assess gait and balance among PwMS.

METHODS

Two independent reviewers screened articles retrieved from PubMed, Web of Science, Scopus, CINAHL, and SportDiscuss. Articles meeting eligibility criteria were summarized and qualitatively discussed. Participant characteristics, validity, reliability, sensitivity and specificity measures, and main results of smartphone-based gait and balance evaluations were summarized. Methodological quality appraisal of the studies was performed using the quality assessment tool for observational cohort and cross-sectional studies.

RESULTS

Eight articles were included in this review. The studies present mostly with low risk of bias. All studies successfully tested the use of smartphone applications in assessing gait and balance among PwMS. In total, 75% of the studies evaluated the validity; 38% evaluated the reliability, sensitivity, and specificity of smartphone applications to assess gait and balance. Of those, all studies except one found smartphone applications to be appropriately valid, reliable, sensitive, and specific in assessing gait and balance. Most studies (88%) reported PwMS and clinicians as their intended users.

CONCLUSION

There is evidence supporting the use of smartphone applications to assess gait and balance among PwMS. Future studies should further examine the psychometric properties of smartphone-based gait and postural control assessments as well as the sensitivity and specificity to improve the interpretation of the results.

Validation of an individualized reduction of falls intervention program among wheelchair and scooter users with multiple sclerosis

INTRODUCTION

Falls are a serious concern for wheelchair and scooter users with multiple sclerosis (MS). Approximately, 75% of the population reports at least one fall in a 6-month period and nearly half report frequent falls. Falls can result in physical injuries and contribute to activity curtailment. Despite the negative consequences, limited evidenced-based fall prevention programs designed specifically for wheelchair and scooter users with MS exist.

PURPOSE

Recognizing the threat falls pose to health and well-being and the dearth of fall prevention programs, the purpose of this study is to perform a structured process evaluation and examine the feasibility and efficacy of a community-based intervention specifically designed to reduce fall incidence among wheelchair and scooter users with MS. Secondary aims of the intervention are to improve functional mobility skills associated with fall risk (e.g., transfer and wheelchair skills, balance), increase knowledge of fall risk factors, decrease fear of falling, and enhance quality of life and community participation.

METHODS

To evaluate our specific aims, a clinical trial will be performed with 160 wheelchair and scooter users with MS. (ClinicalTrials.gov Identifier: NCT03705364). Participants will be recruited to participate in a small group-style community-based program. The content of the program will be based on factors found to be associated with falls among wheelchair and scooter users with MS. These factors include but are not limited to, wheelchair/scooter related characteristics, transfer activities, impaired seated balance, and environmental factors. A physical or occupational therapist, will implement the intervention, which is comprised of 6 sessions that occur once weekly. The incidence of falls, along with an examination of wheelchair/scooter and transfer skills, seated postural control and knowledge of fall related risk factors will be compared between intervention and control participants, with assessment periods occurring prior to the intervention, 1 to 2 weeks after completion of the 6-week intervention session, and 12 weeks after the intervention period is complete.

CONCLUSION

Results from this study will guide the refinement of the intervention program and inform future research among a large and diverse group of wheelchair and scooter users living with MS.
