Overview
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.

Outcomes
Primary Outcomes
Change in pain scores according to visual analog scale (VAS)
Time Frame: 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 Outcomes
- 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)
- Change in pain 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)
- 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)
- 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)
