Sciatica is characterized by radiating pain, functional limitations, reduced flexibility, disturbed sleep, and impaired quality of life. Extracorporeal Shockwave Therapy (ESWT) and Therapeutic Ultrasound are commonly used physiotherapy modalities for pain relief and tissue healing; however, evidence directly comparing their effectiveness remains limited. This randomized controlled trial compares the effects of Shockwave Therapy and Ultrasound Therapy, each combined with conventional physiotherapy, on pain intensity, hamstring range of motion, sleep quality, and quality of life in patients with chronic sciatica.
