Co-creation phase:~Preceding the intervention, a co-creation phase involving healthcare professionals (3), patient-partners (2), and ARSACS researchers (3) will be conducted to develop the exercises for the rehabilitation program and the evaluation scale to determine the level of difficulty of each exercise assigned to participants.~Intervention phase:~Random sampling stratified by gender and level of indoor mobility (unassisted walking, assisted walking, wheelchair) from the Neuromuscular Clinic's registry of 48 participants (24 women and 24 men) will be conducted.~Control phase: All participants will be asked to maintain their usual activities for 12 weeks.~Intervention phase: All participants recruited to the project will complete the home-based rehabilitation program assigned to them for 12 weeks, unsupervised, 20 minutes 3 times a week. Follow-up calls by a physiotherapist will be conducted at weeks 2, 4, 6, 8, 10 and 12.
48 participants (24 women and 24 men) with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) will participate in 2 phases : control phase (12-week usual care) and intervention phase (12-week home-based rehabilitation program). The participants will be evaluated at baseline, week 12 (end of control phase) and week 24 (end of intervention phase) to quantify the effects of an individualized home-based rehabilitation program. Participants will also participate on a focus group at the end of the program to evaluate the acceptability of the program and the perceived changes.
