Summary

This study tests if an injection of hyaluronidase can help reduce muscle stiffness in the arm after a stroke. About 56 people with moderate to severe arm stiffness will receive either the study drug or a placebo, and later switch to the other option. The goal is to see if the treatment improves range of motion and reduces spasticity.
