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.
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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control followed by intervention phase | Experimental | All participants will participate in 2 phases : control phase (12-week usual care) followed by an intervention phase (12-week home-based rehabilitation program). The rehabilitation program consists of three domains of exercises divided by levels of difficulty: sitting balance (16 levels), standing balance (21 levels) and sit-to-stand transfer (12 levels), including 67 exercises. Each individualized home-based rehabilitation program will include 3 to 6 exercises, for a total duration of 15 to 20 minutes. |
