Treatment and study plan

Interferential Current

Device

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

Device

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

Device

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.

Primary outcomes

  1. Pressure Pain Threshold

    Time frame: 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 outcomes

  1. Sensory Discomfort

    Time frame: 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).
