Effects of TENS During the Performance of a Therapeutic Exercise Protocol in Individuals With Knee Osteoarthritis.

The therapeutic exercise program includes a warm-up, resistance, neuromuscular, mobility, and balance exercises. Therapeutic exercises will be performed in up to three sets of 8-12 repetitions or 30-60 seconds each, with rest intervals of 90 seconds between sets.

"TENS will be applied with a portable device, Neurodyn Portable System from Ibramed, while carrying out the entire therapeutic exercise program. The equipment has a two-phase and pulsed symmetric quadratic waveform. 5x5cm adhesive electrodes will be applied to the lateral and medial edges and superior and inferior to the patella, in a crossed manner, surrounding the region.~The parameters established for the protocol of this study are based on a survey already carried out, with continuous pulse mode, frequency of 150Hz, duration of 150us, and amplitude varying from 1-60mA or more as long as tolerated by the study participant, without causing pain. The application time will be proportional to the time of the exercise session, approximately 60 minutes. The researcher will evaluate the need to adjust the current intensity through the pulse amplitude regularly so that the stimulus does not accommodate."

To do this, the device will only be turned on during the first minute of therapeutic exercises. The same TENS parameters as the experimental group will be applied for this."
