This study aims to compare the effectiveness of Extracorporeal Shockwave Therapy (ESWT) with conventional physical therapy in patients with Greater Trochanteric Pain Syndrome (GTPS). GTPS is a common cause of lateral hip pain, often related to gluteal tendinopathy rather than trochanteric bursitis. Sixty patients will be randomly assigned to two groups: ESWT or conventional physical therapy (TENS, hot pack, ultrasound). Pain (VAS), hip function (Harris Hip Score), lower limb function (LEFS), and global improvement will be evaluated at baseline, week 3, and week 12. The purpose of this study is to determine which treatment provides greater pain relief and functional improvement.
Age between 18 and 65 years
Lateral hip pain for at least 3 months
Ability to understand study procedures and provide informed consent
Hip deformities
Gluteus medius, gluteus minimus, or piriformis tendon tears
Lumbar radiculopathy or history of lumbar spine surgery
Recent trauma or active infection in the hip region
Parallel
Extracorporeal Shockwave Therapy (ESWT)
DeviceESWT applied with Elmed Vibrolith Ortho device at 15 Hz, 3 bar, 2000 pulses, 5 sessions over 3 weeks.
TENS; Hot Pack; Ultrasound
Other intervention10 sessions of TENS (20 min), hot pack (20 min), and continuous ultrasound (1.5 W/cm², 5 min).
Change in Visual Analog Scale (VAS) Pain Score
Pain intensity will be assessed using a 0-10 Visual Analog Scale (VAS) for activity, rest, and night pain. The primary endpoint is the change in VAS score from baseline to Week 12.
Harris Hip Score
Hip function will be evaluated using the Harris Hip Score, which includes pain, daily activities, gait, and range of motion parameters. Higher scores indicate better hip function.
Lower Extremity Functional Scale (LEFS)
The LEFS questionnaire will be used to assess lower limb function. It consists of 20 items scored from 0 to 4 (total score 0-80), with higher scores indicating better function.
Global Rating of Change (GROC)
Overall patient-perceived improvement will be assessed using the Global Rating of Change Scale, scored from -1 (worse) to +3 (near normal improvement).
