Arm && Interventions

Group	Intervention	Description
Interferential current group	Interferential current	Interferential current will be applied during 30 minutes to volunteer's forearm. Intensity will be increase until volunteers fell a strong but comfortable paresthesia.
TENS Group	TENS	TENS will be applied during 30 minutes to volunteer's forearm. Intensity will be increase until volunteers fell a strong but comfortable paresthesia.
Aussie current group	Aussie Current	Aussie current will be applied during 30 minutes to volunteer's forearm. Intensity will be increase until volunteers fell a strong but comfortable paresthesia.

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
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).
