Objective
The aim of this study is to investigate the effect of Extracorporeal Shock Wave Therapy (ESWT) on pain and decrease in pain can improve physical function in patients with pre-radiographic knee osteoarthritis.
Subjects and Methods
We enrolled 20 patients with knee pain belonging to K-L grade 0 or 1 on radiological examination, from December 2017 to December 2018. Patients were randomly assigned to the ESWT group (Group I) and the controlled group (Group II). The Group I (n=10) were treated once a week for 3 consecutive weeks using low energy ESWT (1000 shock wave and with low energy level of 0.04mJ/mm2 ,Dornier AR2®) with medical therapy, and the Group II (n=10) received only conventional medical therapy. The focus of shockwave treatment was 0.5cm below the medial tibia plateau in anteroposterior view and 0.5cm from the skin edge in lateral view.
Pain and physical functional outcome was assessed by visual analogue scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, Timed Up and Go (TUG) test and 6-minute walk test (6MWT). All outcome measurements were assessed at baseline, and at 1 and 4 weeks after the treatments were completed.
Results
There are no significant differences in the baseline characteristics and initial values between the two groups. The ESWT group showed significant improvement in VAS score and 6MWT. But, no significantly improvement in the WOMAC and TUG score.
Conclusion
Our result showed that low energy ESWT may be effective for patients with pre-radiographic knee osteoarthritis. The most important finding of the study was that a significantly improvement of ESWT in the long distance walking in patients with pre-radiographic knee OA. Therefore, ESWT can be another useful treatment option for them. |
