Abstract

Background: The main aim of this pilot study was to explore the parameters of posterior gluteus medius muscle thickness on the side of their total hip replacement in patient post-surgery and also to examine if there was any difference between the thicknesses of the posterior gluteus medius muscle in a group randomised to attend a functional exercise class when compared a usual care group post intervention. Purpose: This study was designed to explore the change in thickness of the posterior gluteus medius muscle following rehabilitation intervention in patients post primary total hip arthroplasty. Methods: This was a randomised controlled pilot study in which participants were randomised to either attend a functional exercise class or to a usual care group post total hip replacement. Results: There was a statistically significant increase in the size of the posterior gluteus medius muscle on the operated side on all participants in both groups over the six week period (p < .000).However there was no significant difference found in the size of the posterior gluteus medius between the intervention and control groups on the operated hip side. In the sub group of 10 participants for whom we had non- operative hip measurements also there was no significant change in posterior gluteus medius thickness on the non-operated side over the six week period. Conclusion(s): Significant change in thickness of the posterior gluteus medius on the operated side is evident following recovery post total hip replacement. Implications: This is an inexpensive, safe additional measurement tool that can be used to target specific muscle strengthening and may prove valuable with patients who require additional rehabilitation.
