The efficacy of shock wave therapy in patients with knee osteoarthritis and popliteal cyamella

Abstract This randomized, controlled study was performed to compare the effects of extracorporeal shockwave therapy (ESWT) and ultrasound on the rehabilitation of knee osteoarthritis with popliteal cyamella. One hundred and twenty patients with bilateral moderate knee osteoarthritis (Altman III) and...

Description
Summary:Abstract This randomized, controlled study was performed to compare the effects of extracorporeal shockwave therapy (ESWT) and ultrasound on the rehabilitation of knee osteoarthritis with popliteal cyamella. One hundred and twenty patients with bilateral moderate knee osteoarthritis (Altman III) and popliteal cyamella were selected and randomly assigned to four groups (GI–GIV). Patients in Groups I–III received isokinetic muscular strengthening exercises three times weekly for 8 weeks. Group II received pulse ultrasound treatment for popliteal cyamella three times weekly for 8 weeks, Group III received weekly shock wave therapy for popliteal cyamella for the first 6 weeks, and Group IV acted as controls. The therapeutic effects were evaluated by changes in the arthritic knees range of motion (ROM), visual analogue scale, Lequesne's index, and muscle peak torques after treatment and at follow-up 6 months later. Each treated group exhibited increased muscle peak torques and significantly reduced pain and disability after treatment and at follow-ups. However, only patients in Groups II and III showed significant improvements in ROM after treatment, and only participants in Group III showed immediate improvement in ROM after each treatment. Patients in Group III also showed the greatest increase in muscular strength and the greatest decrease in disability after treatment and at the follow-ups. ESWT is better than pulse ultrasound in rehabilitation of patients with knee osteoarthritis and popliteal cyamella results in more functional improvements.
