Clinical Investigation of the Quality of Life Benefit of Using a Home Walking Exoskeleton for a Population of Multiple Sclerosis Patients.

Summary

The goal of this clinical investigation is to evaluate the effectiveness of home use of a lightweight robotic lower limb exoskeleton as a walking aid device on quality of life in patients with multiple sclerosis with gait disorders. Participants will wear an exoskeleton (Keeogo) for 8 weeks at home during the experimental phase. This phase is compared to an 8-week control phase at home with advice on regular physical activity adapted to their abilities.
