Abstract
OBJECTIVE: Knee osteoarthritis (OA) is the main cause of pain, physical impairment and chronic disability in older people. Electrotherapeutic modalities such as interferential therapy (IFT) and action potential simulation (APS) are used for the treatment of knee OA. In this study, we aim to evaluate the therapeutic effects of APS and IFT on knee OA. METHODS: In this randomized clinical trial, 67 patients (94% female and 6% male with mean age of 52.80 ± 8.16 years) with mild and moderate knee OA were randomly assigned to be treated with APS (n = 34) or IFT (n = 33) for 10 sessions in 4 weeks. Baseline and post-treatment Western Ontario and McMaster Universities Osteoarthritis (WOMAC) subscales, visual analogue scale (VAS) and timed up and go (TUG) test were measured in all patients. RESULTS:VAS and WOMAC subscales were significantly improved after treatment in APS and IFT groups (p < 0.001 for all). TUG was also significantly improved after treatment in APS group (p < 0.001), but TUG changes in IFT was not significant (p = 0.09). There was no significant difference in VAS, TUG and WOMAC subscales values before and after treatment as well as the mean improvement in VAS, TUG and WOMAC subscales during study between groups. CONCLUSION: Short-term treatment with both APS and IFT could significantly reduce pain and improve physical function in patients with knee OA.
