Abstract

Objective: To evaluate the efficacy of insoles in rheumatoid foot reducing pain, improving function and mean peak pressure.

Methods: This was an observational study. 27 patients with foot pain, referred to Orthoses and Prostheses Unit of Unicamp were assessed regarding foot pain, foot deformity, disability (Health Assessment Questionnaire – HAQ-DI) and disease activity (Clinical Disease Activity Index – CDAI). Foot orthoses were prescribed according to each patient’s needs aiming to reduce pain, improve function and reduce the mean peak plantar pressures. The Foot Function Index (FFI) and the pedobarography (FSCAN system) were assessed at base line and after two weeks of intervention.

Results: FFI values decreased in all subscales (pain, disability and activity limitation) with orthoses. No significant difference was noted in the plantar pressure. CDAI and HAQ-DI were associated with FFI but not with plantar pressure. Orthoses were worn on average for was 7.08 hours-day. Minor adverse effects were noted in 7 patients, none of them resulting in treatment interruption.

Conclusion: Insoles may reduce foot pain and disability with no significant improvement in plantar pressure distribution in rheumatoid patients with established disease.
