Effectiveness of High-Intensity Laser Therapy in Patients With Greater Trochanteric Pain Syndrome

Overview

Greater trochanteric pain syndrome causes pain on the outer side of the hip. This study examined whether adding high-intensity laser therapy to exercise improved hip pain and function more than exercise alone. Adults with this condition were randomly assigned to two groups. Both groups followed the same exercise program three days per week for 8 weeks. One group also received high-intensity laser therapy twice weekly for 4 weeks, for a total of eight sessions. Each laser session lasted 15 minutes. The main outcome was the total Harris Hip Score, which assesses hip pain and function. Pain intensity and quality of life were also assessed. Evaluations took place before treatment, 1 month after treatment initiation, and 3 months after completion of the 8-week exercise program.

This single-center, randomized controlled trial was conducted at the Physical Medicine and Rehabilitation Clinic of Uşak Training and Research Hospital. Participants had lateral hip pain lasting at least 3 months. The diagnosis was based on clinical examination and supported by magnetic resonance imaging. Participants were assigned to exercise alone or high-intensity laser therapy plus exercise using a computer-generated random number list. The trial was open-label. Participants, the treating physiotherapist, and the physician performing the assessments knew the treatment assignments. No sham laser treatment was used. The exercise program included gluteal muscle activation, hip abductor strengthening, pelvic stabilization, stretching, and functional exercises. A physician taught the exercises. Participants were instructed to perform three sets of 10 repetitions for each exercise. Exercise intensity and progression were adjusted to pain tolerance and functional capacity. Adherence was monitored through weekly telephone calls. An experienced physiotherapist applied laser treatment around the greater trochanter and the gluteus medius and minimus tendon insertions. Both the participant and the physiotherapist wore protective eyewear. Participants were monitored for adverse events during and after treatment.
