This study was carried out to determine the effect of foot orthoses on pain, gait, and energy expenditure in patients with rheumatoid arthritis. Eighteen patients were evaluated for these parameters. Each patient was given a foot insert or shoe modification suitable for his or her foot deformity. Following 3 months of orthosis use, a significant difference was found in regards to pain (P < .05), step length and stride length (p < .05), and physiological cost index (p < .05). The results suggest that foot orthoses are an important feature in the rehabilitation of the rheumatoid foot.
