OBJECTIVES: To compare balance, foot function and mobility in patients with rheumatoid arthritis with and without foot orthoses. DESIGN: Randomized controlled trial. SETTING: Outpatient rheumatology clinic. SUBJECTS: A total of 94 subjects with rheumatoid arthritis were randomized; of these, 81 were included in the analyses (intervention group 40; control group 41). INTERVENTION: The intervention group received custom-made foot orthoses while the control group received none intervention. MAIN MEASURE: The "Foot Function Index", the "Berg Balance Scale", and the "Timed-Up-and-Go Test" were assessed at baseline an after four weeks. The chosen level of significance was p < 0.05. RESULTS: Average (standard deviation) participant age was 56.7 (+/- 10.6) years old and average disease duration (standard deviation) was 11.4 (+/- 7.2) years. Groups were similar at baseline, except for comorbidity index and race. After four weeks, significant interaction group versus time was observed for Foot Function Index (change intervention group -1.23 +/- 1.58; control group -0.12 +/- 1.16; p = 0.0012) and for Berg Balance Scale (change intervention group 2 +/- 3; control group 0 +/- 3; p = 0.0110), but not for the Timed-Up-and-Go Test (change intervention group -1.34 +/- 1.99; control group -0.84 +/- 2.29; p = 0.0799). CONCLUSION: Foot orthoses improved foot function and balance in patients with rheumatoid arthritis.
