Effects of Including Interferential Current in a Therapeutic Exercise Program in Individuals With Knee Osteoarthritis

The therapeutic exercise program includes a warm-up, resistance, neuromuscular, mobility, and balance exercises.

However, the interferential current will be applied at the end of the therapeutic exercises. In this way, the IC will be used through a device (Endophasys® - NMS-0501, KLD Biosistemas® Equipamentos Eletrônicos Ltda). Four electrodes (8x5 cm), two upper and two lower (forming a square), will be positioned around the center of the knee. The parameters used were as follows: carrier current frequency of 4000 Hz; amplitude modulated frequency of 50 Hz; sweep frequency of 50 Hz; oscillation pattern of 1:1 second, and the amplitude of the current will be increased until the research participants report strong but comfortable and non-painful stimulation paresthesia. The interferential current will be applied for 30 minutes.

The device will only be turned on in the first minute
