Summary
This study tests whether an injection of hyaluronidase, a natural enzyme, can help reduce muscle stiffness and spasticity in the arm after a stroke. Fifty-six adults who had a stroke 4 months to 15 years ago 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 arm function.
