Objective: We investigated the utility of a wearable robot for the fingers that we developed using pneumatic artificial muscles for rehabilitation of patients with post-stroke spasticity.
Methods: Three patients with post-stroke finger spasticity underwent rehabilitation for 20 minutes a day, 5 days a week, for 3 weeks. Passive range of motion, Modified Ashworth Scale (MAS), and circumference of each finger were measured before and after training and compared.
Results: The range of motion and finger circumference increased when using a wearable robot. The MAS improved partially, and no exacerbation was observed.
Conclusions: The wearable robot we developed is useful for rehabilitation of post-stroke spasticity and may improve venous return.

Key words: spasticity, pneumatic artificial muscle, range-of-motion exercise, venous return
