INTRODUCTION: There are many studies on the Greater Trochanteric Pain Syndrome (GTPS), however its relationship with radiographic and biomechanics parameters is not established.
OBJECTIVE: To compare the magnetic resonance images (MRI) of the hip, radiographic parameters of sagittal alignment (pelvic incidence, sacral slope and lumbar lordosis), muscular strength and endurance in women with and without GTPS.
METHODS: Forty women, age over 45, IMC <30 Kg/m2 and sedentary, were recruited and distributed in two groups: GTPS group (GTPSG, n = 20) and Control group (CG, n = 20). All participants underwent MRI scans and X-ray for sagittal alignment analysis in the hip and performed tests for muscular strength and endurance of the hip and trunk.
RESULTS: No differences were found between the GTPSG and CG for the frequency of tendinopathy (P = .30), peritendinitis (P = .10), bursitis (P = .68) and enthesitis (P = .15), however the gluteus medius tendon tear was more prevalent in GTPSG (P = .05). There were no differences in radiographic parameters for pelvic incidence (P > .05), sacral slope (P > .05) and lumbar lordosis (P > .05). The GTPSG showed lower strength of all hip muscle groups (abductors, adductors, flexors, extensors and rotators; P < .01 for all), as well as lower endurance in the Supine Bridge test and Prone bridge test (P < .01).
CONCLUSION: The results of the MRI and radiographic parameters did not differentiate women with and without GTPS. However, the evaluation of muscle strength and endurance can establish the difference between groups.
