Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control group

This group will not receive electrical stimulation. Volunteers will rest during 30 minutes.

Group Type NO_INTERVENTION

No interventions assigned to this group

Interferential current group

Interferential current will be applied during 30 minutes to volunteer's forearm. Intensity will be increase until volunteers fell a strong but comfortable paresthesia.

Group Type ACTIVE_COMPARATOR

Interferential current

Intervention Type 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.

TENS Group

TENS will be applied during 30 minutes to volunteer's forearm. Intensity will be increase until volunteers fell a strong but comfortable paresthesia.

Group Type ACTIVE_COMPARATOR

TENS

Intervention Type 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.

Aussie current group

Aussie current will be applied during 30 minutes to volunteer's forearm. Intensity will be increase until volunteers fell a strong but comfortable paresthesia.

Group Type ACTIVE_COMPARATOR

Aussie Current

Intervention Type 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.
