| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control group | No Intervention | This group will not receive electrical stimulation. Volunteers will rest during 30 minutes. | |
| Interferential current group | Active Comparator | 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 | Active Comparator | 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 | Active Comparator | Aussie current will be applied during 30 minutes to volunteer's forearm. Intensity will be increase until volunteers fell a strong but comfortable paresthesia. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| 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. |
| Measure | Description | Time Frame |
|---|---|---|
| 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. |
| Measure | Description | Time Frame |
|---|---|---|
| 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. |
