(Swiss Paraplegic Centre Nottwil) – Spasticity is the most problematic self-reported secondary medical problem in patients with spinal cord injury. It has the potential to negatively influence quality of life through restricting activities of daily living. Problematic spasticity can cause pain and fatigue, disturb sleep, contribute to the development of contractures and pressure ulcers, and has a negative effect on patients morbidity. For this reason there is enormous interest in therapeutic interventions addressing to decrease spasticity in persons with spinal cord injury. Recently, studies reported positive effects of extracorporeal shock wave therapy on spasticity in patients with stroke, focal limb dystonia and cerebral palsy. To date, no studies are published, assessing the effect of extracorporeal shock wave therapy on focal spasticity in patients with spinal cord injury.
