Participants in this arm will receive a static wrist-hand splint, which is designed to hold the wrist and fingers in a fixed position. The splint is worn according to the rehabilitation protocol, typically for several hours per day, to help maintain joint alignment, prevent contractures, and reduce wrist flexor spasticity. Participants will undergo wrist spasticity assessments at baseline and at the end of the intervention period.

Participants in this arm will receive a dynamic wrist-hand splint, which applies gentle, graded extension forces to the wrist and fingers while allowing limited movement. The splint is worn according to the rehabilitation protocol, typically for several hours per day, to reduce wrist flexor spasticity and improve wrist positioning. Participants will undergo wrist spasticity assessments at baseline and at the end of the intervention period.

Intervention 1: The static wrist-hand splint is a rigid device that holds the wrist and fingers in a fixed position. It is custom-fitted to each participant and worn according to a defined rehabilitation protocol, typically for several hours per day. The static splint provides continuous support to prevent wrist flexor contractures and reduce spasticity. The primary focus is on maintaining proper joint alignment and minimizing muscle hypertonicity.

Wrist flexor spasticity will be assessed using the Modified Ashworth Scale (MAS). Assessments will be performed at baseline before the intervention and after completion of the intervention period. The primary outcome is the change in MAS score, comparing participants using static versus dynamic wrist-hand splints.
