Effects of a Supervised Rehabilitation Program on Disease Severity in Spastic Ataxias

The rehabilitation program will last 12 weeks and consists of three training sessions of 60 minutes per week (2 sessions in a therapy room and 1 session in an adapted pool with multiple levels of water) for a total of 36 sessions. Participants will be divided into 7 subgroups of 6 participants and each sub-group will be supervised by one physiotherapist (PT) and one physiotherapy technologist for safety considerations. It will focus on these three domains: 1) postural control; balance, trunk-limbs and multi-joints control and coordination and 3) functional mobility. Each domain contains a standardized list of exercises with different difficulty levels and specific times allocation. All exercises will be executed by the participants at each session at the appropriate difficulty level. The initial level of difficulty for each exercise will be determined by the PT based on individual results of the pre-intervention assessment and on individual performance, fatigue level and safety.
