Clinical Trial Summary

The effects of different carrier frequencies of interferential current on pain and function in patients with knee arthrosis will be compared

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in pain scores according to visual analog scale (VAS)	A visual analog scale value between 0-10. 0 meaning lack of pain and 10 meaning the worst pain the patient has experienced.	At baseline, on the 3rd week visit (last day of interference therapy) and on the 7th week visit
Secondary	Change in functional status levels according to Western Ontario and McMaster Universities Arhtiritis Incex (WOMAC) scale	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.	At baseline, on the 3rd week visit (last day of interference therapy) and on the 7th week visit

At baseline, on the 3rd week visit (last day of interference therapy) and on the 7th week visit
Secondary	Change in 10 meter walking test score	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.	At baseline, on the 3rd week visit (last day of interference therapy) and on the 7th week visit
Secondary	Change in the number of paracetamol tablets taken in a week	Number of 500 mg tablets taken over one week will be written by subjects.	At baseline, on the 3rd week visit (last day of interference therapy) and on the 7th week visit
