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

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.
