The Efficacy of Interferential Current Treatment on Knee Osteoarthritis

The Efficacy of Interferential Current Treatment on Knee Osteoarthritis: A Randomized Double Blind Study That Compares the Effects of Different Carrier Frequencies

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

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.

Inclusion Criteria:

• Age between 50-80 years
• Knee VAS pain scores ≥ 4
• Kellgren-Lawrence radiologic scores 2 and 3

Exclusion Criteria:

• History of knee surgery
• Inflammatory arthritis
• Paralysis of lower extremities
• Serious cardiovascular disease /presence of cardiac pacemaker
• Severe osteoarhthritis of lower extremity joints other than the knees
