Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

TENS have been used to treatment against pain and reflex modulation. However, the most part of evidence do not show the current density. This parameter has been demonstrated like a important factor in the effect of the current about the outcome measures.

This study show the difference between the same subjective sensation "strong but comfortable" in current density and the relation with the effect about H-reflex.

Study Groups

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

Transcutaneous nerve stimulation

Transcutaneous application of TENS current over the back for a 40 minutes session. The intensity of the current will increase until participants report a "strong but comfortable" sensation, just below motor threshold.

Group Type EXPERIMENTAL

TENS

Intervention Type DEVICE

TENS transcutaneous electrical stimulation over back through the electrotherapy device Myomed 932. (Enraf-Nonius, Delft, Netherlands)

Sham stimulation

Electrodes are placed over the back for a 40 minutes in the same manner as experimental groups, but will be applied a sham electrical stimulation increasing the current intensity of an unconnected channel
