Spinal Muscular Atrophy (SMA)
Conditions
Brief summary
The goal of this clinical trial is to evaluate the long-term effects of isokinetic rehabilitation training in patients with spinal muscular atrophy (SMA). The main question it aims to answer is: • Does isokinetic training at fixed angular velocity improve muscle strength and functional recovery in SMA patients? Participants will: * Perform isokinetic training using a portable device with a fixed angular velocity. * Undergo long-term rehabilitation sessions, with assessments of muscle strength and overall functional improvement over the training period.
Interventions
A child with SMA will use a wearable isokinetic training robot to train the knee joint for three stages. ( Stage 1: 1.5 months=30 sessions; Stage 2 (follow up): 1.5 months=18 sessions, Stage 3(follow up) = 0 session)
