Shock Wave Therapy for Management of Spasticity in Patients With Cerebral Palsy

Spasticity is the most common motor disorder in cerebral palsy (CP). The objectives of his therapeutic approach include; reducing pain, ease of use of orthopedic aids, improving posture, minimizing contractures and deformity, and facilitating mobility and dexterity, with the ultimate goal of maximizing the potential of the patient and promoting their independence and quality of life. The approach to spasticity in CP is complex and presents itself as a great challenge for the rehabilitation team. Radial extracorporeal shock wave therapy (rESWT) has been established in recent years as an effective, non-invasive alternative with hardly any side effects (small bruises or discomfort during the application) for the management of spasticity in patients with CP. rESWT is a relatively new therapy in the field of neurology, in 2010 was published the first clinical trial where shock waves were applied for the management of spasticity in patients with CP. Currently, few works have studied the efficacy of rESWT in patients with CP. In all of them, the results demonstrated the treatment's effectiveness in reducing spasticity locally in people with CP up to 3 months after the application. The group most studied muscle has been the Triceps Surae, and there is a great disparity regarding the doses of treatment applied in each study, especially regarding the number of sessions and the time interval between sessions. The most widely used protocol is 3 rESWT sessions with a time interval of 1 week between session; This protocol was established as the most effective in the treatment of trauma pathology. Despite all the variability in the administration of the dose, we have been able to observe that none of them has studied the effect of rESWT by lengthening the time interval between sessions beyond one week to check whether the therapeutic effects on spasticity can be prolonged over time by applying the same dose. Most of the studies conclude that future research should be aimed at studying the most optimal dose of treatment as well as evaluating the long-term results.
