A Novel Shape Memory Alloy-Based Orthosis for Proximal Interphalangeal Joint Stiffness

The home program with the shape memory alloy-based orthosis contains warm-up part and correction part. The SMA-based orthosis is an improvement over traditional dynamic splint. This corrective device uses shape memory alloy as an elastic component specifically designed to address finger joint stiffness. It provides continuous force for stiff joint in order to address stiffness.

The home program for the stretching group includes active joint range of motion exercises and passive stretching exercises. Participants will follow instructions to perform various joint movements, with a focus on their restricted fingers.
