Brief summary
To compare the effects of low intensity pulsed ultrasound with high intensity continuous ultrasound in knee osteoarthritis
Detailed description
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.
Interventions
Low intensity pulsed ultrasound therapy will use ultrasound with frequency of 1.5 MHz, power intensity of 30 mW/cm\^2 (0.03 W/cm\^2 ) and 20% duty cycle.
High intensity continuous ultrasound therapy will use ultrasound with frequency of 1 MHz, power intensity of 3 W/cm\^2 and 100% duty cycle.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Visual Analog Scale (VAS) | 8 weeks | It is one of the most commonly used measures of pain intensity and it is divided into 10 ordinal ratings with 0 being no pain and 10 being pain as bad as it could be. |
| Western Ontario McMaster University Osteoarthritis Index Inventory (WOMAC) | 8 weeks | This index measures clinically important symptoms of pain, stiffness and function. It consists of 23 questions (5 pain, 2 stiffness and 16 physical function) and the maximum score is 100, indicating the worst outcome while the minimum score is 0, indicating the best outcome. |
| Percentage of participants with skin irritation | 8 weeks | Skin irritation, a possible complication of ultrasound therapy, will be recorded as a dichotomous variable (i.e. present or absent). |
| Percentage of participants with tingling | 8 weeks | Tingling sensation, a possible complication of ultrasound therapy, will be recorded as a dichotomous variable (i.e. present or absent). |
| Percentage of participants with oedema | 8 weeks | Oedema, a possible complication of ultrasound therapy, will be recorded as a dichotomous variable (i.e. present or absent). |
| Percentage of participants with burns | 8 weeks | Burns, a possible complication of ultrasound therapy, will be recorded as a dichotomous variable (i.e. present or absent). |
