Background/Purpose: Rheumatoid arthritis (RA) is a systemic inflammatory disease characterized by peripheral polyarthritis, which may cause joint destruction and deformities, resulting in reduced function and disability. The joint involvement of the foot occurs in 85-100% of the patients with RA. The use of insoles has been a routine in the treatment of rheumatoid feet, despite the weak evidence of its use in randomized controlled trials. The aim of the present study were to evaluate the effectiveness of the use of insoles for foot pain, function, gait, foot load distribution, quality of life and patient satisfaction regarding the use of the insoles in patients with RA.
Methods: Eligible patients included women classified as RA according to the ACR criteria, aged 18-65 years old with pain in feet between 3 and 8 on a 10-cm pain scale (VAS) for walking; functional classes I, II, and III. Of the 208 patients evaluated, 80 met the eligibility criteria and were randomized into experimental (EG) or control groups (CG). The EG group made use of EVA insoles with medial arch and retrocapital support, and CG group employed flat insoles during the study. Pacients were evaluated for pain (VAS) when walking and at rest, function (HAQ), function of the feet (FFI), quality of life (SF-36), 6-minute walk test, satisfaction with the treatment (Likert scale) and dynamics baropodometry (Pro FootWalk, AMcube ®, Gargas, France) at baseline, 45 days (T45), 90 days (T90) and 180 days after randomization by a blinded evaluator.
Results: Thirty-nine and 41 patients were randomly divided into EG and CG groups, respectively. The groups were homogeneous at baseline regarding clinical and demographic characteristics. In the comparison between the groups over time, we found better results for the EG with a statistical difference for pain during walking and at rest on the right and left foot (p <0.001), stride length (p = 0.001), and satisfaction with the treatment (p = 0.039). For other variables, we found no statistically significant difference between groups.
Conclusion : The use of insoles with medial arch and retrocapital support is effective in reducing pain during walking and at rest on both feet, increasing stride length and satisfaction with the use of insoles.
