This study tested three different treatment approaches for tennis elbow (pain in the outer elbow), a common condition affecting the forearm muscles. The treatments included shock wave therapy, a dietary supplement containing collagen and hyaluronic acid, and therapeutic exercises. The results showed that combining all three treatments was most effective, providing the best pain relief, functional improvement, and grip strength recovery within 30 days. The findings suggest that combining different treatment approaches may work better together than using them separately.
