Keywords
interferential current, knee osteoarthritis, pain
Brief summary
The effects of different carrier frequencies of interferential current on pain and function in patients with knee arthrosis will be compared
Detailed description
60 patients with knee osteoarhthritis will be enrolled in the study. Subjects will be randomized to 3 groups. All patients will receive interferential currents to both their knees, with different carrier frequencies (2, 4 and 8 kilohertz (kHz) respectively). The effect of different types of carrier frequencies on pain, 10 meter walk test will be analysed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in pain scores according to visual analog scale (VAS) | At baseline, on the 3rd week visit (last day of interference therapy) and on the 7th week visit | A visual analog scale value between 0-10. 0 meaning lack of pain and 10 meaning the worst pain the patient has experienced. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in functional status levels according to Western Ontario and McMaster Universities Arhtiritis Incex (WOMAC) scale | At baseline, on the 3rd week visit (last day of interference therapy) and on the 7th week visit | Womac scale is a questionnaire assessing patients' level of pain and functional status. Scores. Scores range from 0 to 96, 0 representing best and 96 representing worst scores. Pain, stiffness and functional limitation subscores are added up to obtain a total WOMAC score. |

| Change in 10 meter walking test score | At baseline, on the 3rd week visit (last day of interference therapy) and on the 7th week visit | This test is a measure that is used to assess walking speed in meters per second over 10 meters. It is used to determine functional mobility. |
| Change in the number of paracetamol tablets taken in a week | At baseline, on the 3rd week visit (last day of interference therapy) and on the 7th week visit | Number of 500 mg tablets taken over one week will be written by subjects. |
