Recovering movement after a stroke or spinal injury takes intensive, repetitive therapy. Rehabilitation exoskeletons, powered frames worn on the legs or arms, support and guide a patient's movements, helping them practise walking or reaching with assistance that adjusts to their progress.
Consistent, measured support lets patients do more repetitions and gives therapists data on improvement, and some people use the devices for mobility day to day. The systems are costly and must be fitted and supervised by professionals, and they aid rather than cure, but they have expanded what rehabilitation can offer to people regaining movement.
