Effects of a footwear intervention on foot pain and disability in people with gout: a randomised controlled trial

Abstract Background There is limited evidence supporting the long-term effect of a foot care package that includes footwear for people with gout. The aim of this study was to investigate the effectiveness of a footwear intervention on foot pain and disability in people with gout over 6 months. Methods Participants with gout (n = 94) were randomly allocated to either a control group (podiatric care and gout education) or footwear intervention group (podiatric care and gout education plus a commercially available athletic shoe). Measurements were undertaken at baseline and 2, 4, and 6 months. Primary outcome was foot pain severity. Secondary outcomes were overall pain, foot impairment/disability, footwear comfort, fit, ease and weight. Data were analysed using repeated measures models. Results Baseline foot pain scores were low, and no differences in foot pain scores were observed between groups over 6 months (adjusted effect estimate: − 6.7, 95% CI − 16.4 to 2.9, P = 0.17). Improvements between groups in overall pain scores (adjusted effect estimate: − 13.2, 95% CI − 22.2 to − 4.3, P 0.05). Conclusions Addition of footwear to a foot care package did not improve foot pain in people with gout. Short-term improvements in overall pain and foot impairment/disability and more durable improvements in footwear comfort and fit were observed with the footwear intervention.
