Summary

This randomized controlled study aims to compare the effects of synchronous and asynchronous exercise programs on individuals diagnosed with relapsing-remitting multiple sclerosis (RRMS). Participants meeting the inclusion criteria (EDSS score between 2 and 5.5, aged 18-55) were randomly assigned to either the Synchronous Exercise Group (SEG) or the Asynchronous Exercise Group (ASEG). The synchronous program was delivered via live online sessions using Google Meet and WhatsApp video calls, while the asynchronous program consisted of pre-recorded exercise videos accessible to participants. Both programs included structured exercises focusing on functional capacity, muscle strength, fatigue, independence, and quality of life. The sample size was determined using G\*Power software based on previous studies in individuals with multiple sclerosis, targeting a total of 16. Statistical analyses will be conducted using SPSS 26.0. Parametric and non-parametric tests will be used depending on data distribution, with significance set at p \< 0.05. The study seeks to improve accessibility to exercise programs for MS patients and provide evidence for the efficacy of remotely delivered synchronous versus asynchronous rehabilitation models.

Detailed description

This randomized controlled trial was designed to evaluate and compare the effects of synchronous and asynchronous structured exercise programs in individuals diagnosed with relapsing-remitting multiple sclerosis (RRMS). The main aim was to investigate differences in fatigue, functional exercise capacity, muscle strength, functional independence, and quality of life between the two intervention models. Participants were recruited according to the inclusion criteria: age 18-55, RRMS diagnosis according to McDonald criteria, Expanded Disability Status Scale (EDSS) score between 2 and 5.5, no relapse within the last six months, and access to technological infrastructure (internet, camera, microphone). Exclusion criteria included other neurological diagnoses, cardiovascular, vestibular, or orthopedic conditions limiting exercise participation, cognitive impairment (Mini-Mental State Examination \<24), fall risk (Timed Up and Go \>14.2 s), psychiatric disorders, vision or hearing impairments, pregnancy, or concurrent physiotherapy programs. Participants were randomly assigned into two groups (n=20 each): the Synchronous Exercise Group (SEG) and the Asynchronous Exercise Group (ASEG). Both groups performed a 12-week combined exercise program (2 sessions per week, 40 minutes per session) consisting of strengthening, core stabilization, and respiratory exercises, followed by a 3-month follow-up period. The structured program included warm-up (10 min: rhythmic stepping, diaphragmatic breathing, shoulder mobility), main exercises (25 min: bridging, plank, squats, seated upper-limb strengthening), and cool-down (5 min: stretching and relaxation). The synchronous group performed exercises live through Google Meet or WhatsApp video calls under real-time physiotherapist supervision. The asynchronous group followed pre-recorded video sessions and submitted exercise logs weekly; feedback and follow-up were provided via e-mail or phone. Assessments were conducted at four time points: baseline (D0), mid-intervention (4th week; D1), post-intervention (12th week; D2), and after a 3-month follow-up (D3). Statistical analyses were performed using SPSS 26.0; normality was assessed via the Kolmogorov-Smirnov test. Within-group comparisons used paired-sample t tests or Wilcoxon tests, and between-group differences were analyzed using independent t tests or Mann-Whitney U tests. Repeated-measures ANOVA was applied for follow-up analyses, with significance set at p \< 0.05. The study hypothesized that synchronous telerehabilitation would result in superior outcomes compared to asynchronous exercise delivery in terms of fatigue reduction, muscle strength improvement, and enhanced functional capacity.

Interventions

Type	Name	Description
OTHER	Combined Exercise Program (Synchronous Delivery)	Participants receive a 12-week structured combined exercise program delivered twice weekly via live online video sessions (Google Meet or WhatsApp). Each session lasts approximately 40 minutes and included 10 minutes of warm-up, 25 minutes of strengthening and core stabilization exercises, and 5 minutes of cool-down stretching. Exercise intensity is maintained between 12 and 15 on the Borg Rating of Perceived Exertion scale. Rest periods are adjusted individually. Exercises are supervised in real time by a physiotherapist, who monitored participants' form, safety, and perceived fatigue throughout each session
OTHER	Combined Exercise Program (Asynchronous Delivery)	Participants follow the same 12-week structured exercise program twice weekly using pre-recorded instructional videos. The program consists of warm-up, strengthening/core, and cool-down components identical to the synchronous arm. Participants receive detailed guidance to ensure correct posture and performance, logged each session in exercise diaries, and submitted weekly feedback to researchers. Investigators review exercise logs and provided individualized feedback via e-mail or phone. In case of difficulties, participants can contact the research team for assistance
