Objectives: Extra corporeal shock wave therapy (ESWT) has been evaluated for the knee osteoarthritis (KOA) treatment, recently .We aim to investigate the therapeutic effects of ESWT for the treatment of patients with moderate KOA, compared with the conventional physiotherapy.
Materials and Methods: In this randomized controlled clinical trial, a total of 75 adult patients (70 female and 5 male) with moderate KOA were randomly assigned into three groups: ESWT with exercise, physiotherapy (PT) with exercise and exercise only. Patients were evaluated using visual analogue scale (VAS), Western Ontario and McMaster universities (WOMAC), knee range of motion (ROM), time to up and go test (TUG) and High Sensitivity C-Reactive Protein (HSCRP).
Results: In either treatment group, VAS, WOMAC and TUG improved toward 3 weeks and this improvement sustained till the 7-weeks follow-up session, significantly. Also, patients’ knee ROM improved in ESWT group throughout the course of study, significantly we observed no significant difference between the ESWT and PT after 3 weeks and both were superior to exercise alone. In the 7-weeks evaluation, patients in ESWT group, reported lower pain (50.42% improvement in VAS compared to 30.31%; P<0.001 and 28.26%; P=0.008 in PT and exercise group, respectively) and better improvement in knee extension ROM (P= 0.004 and <0.001, respectively).
Conclusions: Even though PT and ESWT seem to be more effective than exercise alone in the short-term treatment of patients suffering from KOA, medium intensity ESWT is better than PT and exercise in medium-term rehabilitation of these patients resulting in better pain-relieving and knee ROM improvement.
