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.

This study aimed to explore the potential of a mobile health (mHealth) application (app) to support the delivery of a fall prevention and management program, Individualized Reduction of FaLLs (iROLL), for people with spinal cord injury (SCI) and multiple sclerosis (MS) who use wheelchairs and scooters (WC/S) full-time by seeking end-users' input into the functioning and ongoing design of the iROLL-O + mobile app. Two focus group discussions included nine adults with SCI or MS who used a WC/S for at least 75% of mobility, who experienced at least one fall in the past three years and have internet and access to an internet-capable device. One group had prior iROLL experience ( = 4); while the other had none ( = 5).

Background: Falls are prevalent among people living with Multiple Sclerosis (PwMS) and Spinal Cord Injury (PwSCI) who use wheelchairs or scooters (WC/S) full time, however, there is a scarcity of evidence-based fall prevention and management programs.
Objective: To describe the systematic translation of an in-person fall prevention and management program (Individualized Reduction Of FaLLs - iROLL) for PwMS to an online platform, extending its scope to include PwSCI, and to evaluate the preliminary useability, usefulness, and safety of the intervention.
Methods: iROLL was systematically translated to an online platform (iROLL-O).

Introduction: People with multiple sclerosis and gait impairment are particularly susceptible to facing restrictions in their participation. This study aims to investigate (a) which contextual factors within the framework of the International Classification of Functioning, Disability and Health (ICF) are relevant for participation from the perspective of people with multiple sclerosis and gait impairment who (intend to) use mobility assistive devices, and (b) how these contextual factors shape the subjective facets of participation, including a sense of connection, efficacy and meaning, based on the social identity approach to health and well-being.
Methods: We conducted a qualitative analysis on data gathered from four online focus group interviews, each involving four to six people with multiple sclerosis and gait impairment who (intend to) use mobility assistive devices (totalling N = 19), and 12 individual online interviews conducted with participants from the focus group interviews.

Purpose: The purpose of this systematic review of the literature is to build understanding of the key elements and recommendations for the design of mHealth technology for individuals using wheelchairs and/or scooters and identify key features associated with the use of mHealth to support healthy behaviour changes for this population.
Materials And Methods: Eight major electronic databases were systematically searched to identify mobile health (mHealth) interventions, which targeted adult WC/S users. Independent reviewers used Endnote and Covidence to manage articles meeting review criteria and to exclude duplicates.

Purpose: To evaluate the psychometric properties of a Fall Concerns Scale for people who use Wheelchairs and Scooters (FCS-WC/S).
Materials And Methods: Developed by fall prevention experts, FCS-WC/S underwent refinement through interdisciplinary reviews and focus groups with researchers, clinicians, and individuals who use WC/S full-time. The psychometric evaluation involved adults who used WC/S for ≥1 year and had ≥1 fall in the previous 3 years, recruited between April and September 2022.
