About

The purpose of this study is demonstrate the importance of density current of TENS in the effect about H-reflex in healthy volunteers.

Full description

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.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Crossover Assignment

Masking: Double Blind

---

20 participants in 2 patient groups

Transcutaneous nerve stimulation

Experimental group

Description:

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.

Treatment:

Device: TENS

Sham stimulation

Sham Comparator group

Description:

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

Treatment:

Device: Sham stimulation
