Worse self reported outcomes but no limitations in performance based measures in patients with long standing hip and groin pain compared with healthy controls
PurposeThis study aimed to evaluate patient reported outcomes as well as lower extremity and trunk muscle function in patients with long standing hip and groin pain, in comparison with matched, healthy controls. It was hypothesized that patients with long standing hip and groin pain would report more deficiency on the Copenhagen Hip and Groin Outcome Score (HAGOS) and have worse outcomes on performance based measures than healthy controls.MethodsNineteen patients with long standing hip and groin pain and 19 healthy, activity level age gender and weight matched controls were assessed with the HAGOS for self reported outcomes, and a parallel squat (w/kg) single leg triple jump (cm) single leg rise (n) barbell roll out of height) and plank test (s) for performance based measures. Independent sample t test was performed to assess between group differences. The paired t test was used to analyse between limb differences in unilateral performance tasks.ResultsThe patients had worse scores than the controls in all HAGOS subscales (p 0.001) while no statistically significant differences were observed for any performance measure between groups or between symptomatic and non symptomatic limbs.ConclusionsDespite significant self reported functional limitations on the HAGOS, there were no significant differences between groups in performance based strength or power measures. The results of this study highlight the need to identify performance based measures, sensitive to functional deficiencies in patients with long standing hip and groin pain in order to complement the clinical picture obtained by patient reported outcomes such as the HAGOS.Level of evidenceIII.
