“This compilation focuses on spasticity, a condition which results in an abnormal increase in muscle tone caused by injury of nerve pathways within the brain responsible for muscle movement control. The authors assess the effectiveness of extracorporeal shock wave therapy, a promising new non- invasive method, in the reduction of muscle spasticity. Selective dorsal rhizotomy, a successful neurosurgical technique for spasticity treatment, is subsequently described. In the postoperative phase, rehabilitation plays an essential role, supplemented by possible corrective orthopedic interventions. In general, physical therapy methods and rehabilitation techniques constitute suitable non-pharmacological options for spasticity, and they are primary care treatments used in early treatment. The closing study analyzes the effectiveness of upper limb orthosis for the treatment of spasticity, range of motion and functionality issues of persons with cerebral palsy and acquired brain damage”–
