Intervention

Device:
• Interferential current
Interferential current will be applied during 30 minutes to volunteer's forearm at a strong but comfortable intensity. Carrier frequency will be set at 4 kilohertz (kHz) and modulated frequency will be set at 100 Hz.
• Aussie Current
Aussie current will be applied during 30 minutes to volunteer's forearm at a strong but comfortable intensity. Carrier frequency will be set at 4 kHz and modulated frequency will be set at 100 Hz.
• TENS
TENS will be applied during 30 minutes to volunteer's forearm at a strong but comfortable intensity. Pulse duration will be set at 125 microseconds and frequency will be set at 100 Hz.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pressure Pain Threshold	Pressure Pain Threshold will be measured using a digital pressure algometer SOMEDIC type II. The applied force will be measured in Newton (N).	Baseline, 15 minutes after the beginning of electrical stimulation, 30 minutes after the beginning of electrical stimulation, and 20 minutes after electrical stimulation.
Secondary	Sensory Discomfort	Sensory Discomfort will be measured using a 10 cm visual analogue scale (VAS). The degree of discomfort will be measured in centimeters (cm).	15 and 30 minutes after the beginning of electrical stimulation.
