Hip-Joint Posture and Movement Alterations Are Associated With High Interference of Pain in the Life of Patients With Greater Trochanteric Pain Syndrome

Abstract

ObjectiveGreater trochanteric pain syndrome (GTPS) is a common condition that can cause lateral hip pain. The single-leg-squat test (SLST) may be used by physicians in primary care environments to evaluate patients’ dynamic stability. The aim of this study was to evaluate the dynamic stability and strength of lateral abduction hip movements in primary care patients with GTPS in relation to their perceived pain interference in life. MethodsA descriptive observational study was carried out in a primary health care center. Fifty-four participants with GTPS were included in this study and divided into lower- and higher-interference groups (n = 30 and 19, respectively) according to the Graded Chronic Pain Scale. Participants were evaluated for their lateral abduction hip strength and the SLST. ResultsThe SLST showed a statistically significant difference between groups with respect to hip-joint posture and movement level (P = .043) but not for other SLST domains or lateral abduction hip strength (P > .05). ConclusionPatients with GTPS with more pain interference in their lives had poorer dynamic stability with respect to hip-joint posture and movements based on the SLST but did not present impaired lateral hip abduction strength in comparison with those who perceived lower pain interference in life.
