Brief summary

The objective of this study is to compare the hypoalgesic effects of TENS, Interferential current and Aussie current in pressure pain threshold and sensory discomfort in healthy subjects.

Interventions

DEVICEInterferential 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.

DEVICEAussie 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.

DEVICETENS

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.

Design outcomes

Primary

Measure	Time frame	Description
Pressure Pain Threshold	Baseline, 15 minutes after the beginning of electrical stimulation, 30 minutes after the beginning of electrical stimulation, and 20 minutes after electrical stimulation.	Pressure Pain Threshold will be measured using a digital pressure algometer SOMEDIC type II. The applied force will be measured in Newton (N).

Secondary

Measure	Time frame	Description
Sensory Discomfort	15 and 30 minutes after the beginning of electrical stimulation.	Sensory Discomfort will be measured using a 10 cm visual analogue scale (VAS). The degree of discomfort will be measured in centimeters (cm).
