Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Comparison between high and low frequency percutaneous electrical nerve stimulation as treatment of myofascial chronic neck pain. The main hypothesis is that low frequency treatment will have more hypoalgesic effects than high frequency, and low frequency effects will last longer.

Study Groups

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

Low frequency

Percutaneous electrical nerve stimulation with frequency of 2 Hz and 120 microseconds of pulse width will be applied.

Group Type EXPERIMENTAL

Low frequency

Intervention Type PROCEDURE

A dry needling on trapezius muscle is performed, until two local twitch responses are obtained. The needle is kept inside the trigger point, as it will be the negative electrode, and an adhesive electrode will be added as the positive one. After that, a low frequency TENS is applied, at 2 Hz frequency and 120 microseconds of pulse width.

High frequency

Percutaneous electrical nerve stimulation with frequency of 120 Hz and 200 microseconds of pulse width will be applied.

Group Type ACTIVE_COMPARATOR

High frequency

Intervention Type PROCEDURE

A dry needling on trapezius muscle is performed, until two local twitch responses are obtained. The needle is kept inside the trigger point, as it will be the negative electrode, and an adhesive electrode will be added as the positive one. After that, a high frequency TENS is applied, at 12o Hz frequency and 200 microseconds of pulse width.
