Interferential
The individuals are treated acutely with IES during 30 min, providing a continuous flow of symmetrical rectangular interferential current biphasic pulses using bipolar electrodes with two channels and a slope of 1/5/1. The fixed current is adjusted to 4000 Hz, with the current AMF at 100 Hz and an AMF variation of 25 Hz (25% of AMF).
Interferential Placebo
The same instructions and electrode positions were provided to the placebo, although the equipment did not provide any stimulation current
