Nonsurgical management of the foot and ankle affected by rheumatoid arthritis.

Rheumatoid arthritis frequently affects foot and ankle function, leading to pain, difficulty with ambulation, and disability. The purpose of this article is to describe common foot and ankle deformities associated with rheumatoid arthritis and present state-of-the-art nonsurgical management strategies. Physical impairments thought to be commonly associated with limitations of function and practical interventions for alleviating those impairments or reducing the impact of the impairment on ambulation are identified. Examples of rehabilitation interventions discussed include prescription footwear, custom and premolded foot orthoses, hindfoot orthoses, ankle-foot orthoses, shoe modifications, therapeutic exercises, and patient education. Early and aggressive attempts at prevention, delay, or correction of foot and ankle pathomechanics related to rheumatoid arthritis may play a key role in helping patients maintain an active ambulatory lifestyle.
