Summary

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.

Conditions

• Neck Pain
• Chronic Pain
• Myofascial Pain Syndrome

Interventions

Type	Name	Description
PROCEDURE	Low frequency	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.
PROCEDURE	High frequency	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.
