Background: Physical therapy and biomechanical interventions for patients with hip OA should aim to reduce pain, improve function and restore or maintain gait patterns close to normal. The purpose of this study was to evaluate the effect of a biomechanical therapy on the pain, function, quality of life and spatio-temporal gait patterns of patients with hip OA. Methods: 60 patients with hip OA were examined before and after 12 weeks of using the biomechanical device and treatment (AposTherapy). Patients were evaluated using the WOMAC questionnaire for pain and function and the SF-36 Health Survey for quality of life. Patients also underwent a computerized gait test. Results: After 12 weeks of treatment, a significant improvement was found in the patients' velocity, step length and cadence (P≤0.001). WOMAC-pain, WOMAC-stiffness and WOMAC-function subscales were significantly improved compared with baseline (P≤0.001). SF- 36 physical score subscale improved significantly (P=0.007), whereas the SF-36 mental subscale improved but did not reach the statistical significance threshold. Conclusions: Patients with bilateral hip OA treated with the examined therapy for 12 weeks showed statistically and clinically significant improvements in pain, function and gait patterns. These findings suggest that this treatment may be an additional useful tool for conservatively treating patients with hip OA. Further RCT studies are needed to evaluate the effect of the examined therapy on hip OA population.
