Abstract:
AbstractBackgroundFoot orthoses and footwear interventions are advocated for the management of lower limb musculoskeletal conditions including the hip, but much of the research is focused on knee disorders. The aim of this systematic review was to synthesise the literature that investigates the use of foot orthoses or footwear in people with hip‐related pain.MethodsMEDLINE, EMBASE, CINAHL, AMED and SPORTDiscus were searched from inception to March 2023. Randomised controlled trials (RCT), cohort and pre‐post studies reporting on footwear and foot orthoses interventions, in participants with hip‐related pain, were eligible for inclusion. Outcomes included pain, physical function, and quality of life (QoL). Effect sizes were calculated where sufficient data were available. Reporting quality was assessed using the Cochrane Risk of Bias Tool (Rob‐2) and the Joanna Briggs Institute Checklist. The overall quality of evidence was rated according to the Grading of Recommendations, Assessment, Development, and Evaluations framework.ResultsOf the seven included studies (n = 266 participants), there was one RCT, one cohort and five single‐group pre‐post designs. Interventions included customised and non‐customised arch supports, heel lifts, and footwear modifications, used in the following hip conditions: trochanteric pain, non‐specific hip pain, hip osteoarthritis, and leg length dysfunction following total hip arthroplasty. Meta‐analysis was possible for outcomes in two studies, demonstrating moderate improvement in pain following foot orthoses use. Overall certainty of evidence ranged from very low to low.ConclusionSingle‐group pre‐post study designs describe positive relationships between foot orthoses and footwear use and improvements in hip pain, function, and QoL. However, these results were not supported by the only available RCT. Given this is a relatively inexpensive and non‐invasive treatment approach, further rigorous studies are warranted.
