The Efficacy of Interferential Current Treatment on Knee Osteoarthritis

Not Applicable
Completed
Conditions
Knee Osteoarthritis
Interventions
Device: Interferential current
Registration Number
NCT04015323
Lead Sponsor
Ege University
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.

Primary Outcome Measures
NameTimeMethod
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 Outcome Measures
NameTimeMethod
Change in the number of paracetamol tablets taken in a weekAt 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.

Change in pain status levels according to Western Ontario and McMaster Universities Arhtiritis Incex (WOMAC) scaleAt 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 scoreAt 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 functional status levels according to Western Ontario and McMaster Universities Arhtiritis Incex (WOMAC) scaleAt 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.
