Abstract
Stiff-person syndrome (SPS) is a rare neurological disorder that causes muscle rigidity and stiffness of the trunk and proximal limb muscles, leading to movement difficulties and impaired function. Due to the rarity of the disease, studies on the benefit of rehabilitation for this disorder are quite limited. A 46-year-old female patient diagnosed with SPS complained of imbalance and movement difficulty. We prescribed therapeutic exercises aimed to reduce the stiffness of the trunk and proximal limbs and improve her function. Baseline measurement of the patient's range of motion, muscle power and tone, balance and functional abilities were taken pre- and post-program. Outcome measures showed a general improvement in the patient's muscle flexibility, balance, and functionality.
