Extracorporeal Shockwave Therapy as an Additional Treatment for Spasticity Secondary to Spinal Cord Injury

Spasticity is a common consequence of spinal cord injury and can have a profound impact on quality of life. The goal of this study is to learn if an intervention called focused extracorporeal shockwave therapy can enhance the effectiveness of injections received for spasticity, such as Botox. The main questions this study seeks to answer are whether shockwave therapy and toxin injection 1) can improve spasticity symptoms greater than toxin injection alone, and 2) change the structure of the injected muscles. Researchers will compare the group who receives both shockwave therapy and toxin injection to a group who receives only toxin injection. Participants will be asked to visit the clinic five times over the span of three months. The first three visits will occur on three consecutive weeks, during which participants will receive shockwave therapy or the sham therapy. The final two visits
