Objective: Common data elements (CDEs) help harmonize data collection across clinical trials and observational studies, allowing for cross-study and cross-condition comparisons. Although CDEs exist for multiple clinical conditions and diseases, this work was extended only recently to neurorehabilitation research.

Design: Subgroups of clinical neurorehabilitation investigators operationalized a domain definition, selected applicable CDEs from 23 existing National Institute of Neurological Disorders and Stroke (NINDS) CDE projects and National Institutes of Health (NIH) CDE repositories, and identified areas needing further development.

Background: There is emerging evidence for poor health outcomes among Black people with MS, and Black people with MS may have worse walking performance than White counterparts.

Purpose: The current study examined if Black participants with MS had slower walking speed (timed 25-foot walk, T25FW) and shorter walking distance (six-minute walk, 6MW) than White participants, and if these differences were accounted for by demographic variables, physical activity, disease/clinical characteristics, and Social Determinants of Health (SDOH).

Method: The analysis included samples of Black (N = 105) and White (N = 246) participants with MS who completed the T25FW and 6MW, underwent a neurological exam for generating an Expanded Disability Status Scale (EDSS) score, and provided data on demographic variables (i.

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).

Article Synopsis
  • Multiple sclerosis (MS) significantly impacts mobility in young and middle-aged adults, and the Patient Determined Disease Steps (PDDS) scale is used to measure disability levels, particularly in terms of walking function.
  • This study aimed to determine if the middle-range PDDS scores accurately represent different levels of walking dysfunction through a detailed analysis involving various tests and scales among 374 participants.
  • Results indicated strong correlations between PDDS and various walking measurements (like EDSS and T25FW), suggesting that the PDDS can effectively reflect varied walking disabilities in MS patients, though its relationship with fatigue and quality of life is weaker.

Practicing clinicians in neurorehabilitation continue to lack a systematic evidence base to personalize rehabilitation therapies to individual patients and thereby maximize outcomes. Computational modeling- collecting, analyzing, and modeling neurorehabilitation data- holds great promise. A key question is how can computational modeling contribute to the evidence base for personalized rehabilitation? As representatives of the clinicians and clinician-scientists who attended the 2023 NSF DARE conference at USC, here we offer our perspectives and discussion on this topic.

Physical rehabilitation and exercise training have emerged as promising solutions for improving health, restoring function, and preserving quality of life in populations that face disparate health challenges related to disability. Despite the immense potential for rehabilitation and exercise to help people with disabilities live longer, healthier, and more independent lives, people with disabilities can experience physical, psychosocial, environmental, and economic barriers that limit their ability to participate in rehabilitation, exercise, and other physical activities. Together, these barriers contribute to health inequities in people with disabilities, by disproportionately limiting their ability to participate in health-promoting physical activities, relative to people without disabilities.

Article Synopsis
  • Successful translation of exercise interventions into clinical practice requires a balance between treatment fidelity (how closely the intervention follows the original plan) and adaptability (making changes to fit different settings).
  • The study analyzed behavioral coaches' experiences through surveys, team meeting transcripts, and session audits to identify challenges and adaptations made during the STEP for MS Trial, particularly during the COVID-19 pandemic.
  • Key findings showed that coaches adapted the program by shifting to virtual sessions, modifying equipment, and adjusting delivery methods while ensuring the core components of the exercise program remained intact, proving that fidelity can be maintained even with necessary changes.

Impaired mobility is amongst the most debilitating symptoms reported by people with multiple sclerosis (MS). Historically, it has been viewed that walking impairments in people with MS are directly caused by the physical damage to the neurons in the central nervous system (CNS) which results from the immunopathology of MS. However, research from over the past 4 decades has revealed that physical function in people with MS is also affected by skeletal muscle dysfunction characterized by a reduced capacity to produce, regulate, and sustain the force-generating muscle contractions that propel human movement.

Background: During spring and summer 2020, US states implemented COVID-19 pandemic restrictions, resulting in the closure of rehabilitation facilities and, with them, some of the clinical trials that were taking place. One such trial was the Supervised Versus Telerehabilitation Exercise Program for Multiple Sclerosis ("STEP for MS") comparative effectiveness multiple sclerosis (MS) exercise trial. Although 1 study arm was implemented via telerehabilitation, the comparative arm took place in rehabilitation facilities nationwide and was subsequently closed during this time frame.
