Use of different doses of pulsed short waves in the treatment of patients with osteoarthritis of the knee
Keywords:
Pain, Physical therapy modalities, OsteoarthritisAbstract
Objective
To evaluate the effectiveness of the application of pulsed short waves in the reduction of pain, and functional improvement in patients with osteoarthritis of the knee, and also to investigate changes in treatment between the groups with doses of 17 kilojoules or 33 kilojoules.
Methods
Forty-two female subjects with type II or III osteoarthritis of the knee and over 40 years of age, participated in this study, and were submitted to the application ofpulsed short wave doses of 17 or 33 kilojoules. They were evaluated by means of a knee and osteoarthritis score questionnaire, visual analog pain scale and knee flexion goniometry.
Results
The active groups of 17 or 33 kilojoules had less pain and improved function when compared with the control group. There was, however, no significant difference between the active groups.
Conclusion
This study demonstrated that the application of both 17 and 33 kilojoule doses of pulsed short waves is efficient in pain reduction and improved function in the treatment of osteoarthritis of the knee.
