Low Intensity Pulsed Ultrasound Versus High Intensity Continuous Ultrasound Therapy in Knee Osteoarthritis

A Comparative Study of Low Intensity Pulsed Ultrasound (Osteotron IV) Versus High Intensity Continuous Ultrasound Therapy in Knee Osteoarthritis

To compare the effects of low intensity pulsed ultrasound with high intensity continuous ultrasound in knee osteoarthritis

Knee osteoarthritis is a common disorder affecting elderly and obese. Currently, there are 3 types of treatment; pharmacological, non-pharmacological and surgery. Though ultrasound, a non-pharmacological treatment, is increasingly used in knee osteoarthritis, the advantages and disadvantages of low intensity pulsed ultrasound (LIPUS) and high intensity continuous ultrasound (HICUS) are yet to be clarified. Therefore, a randomized control trial will be done to compare LIPUS and HICUS in participants with knee osteoarthritis presenting to Department of Physical Medicine and Rehabilitation, Yangon General Hospital, Myanmar.
