Study Overview
Brief 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.

Outcomes
Primary Outcomes
Pain
Time Frame: Changes on pain will be assessed during one month follow up. Baseline will be measured on the first day and one month later pain score will be reassessed.
Subjective feeling expressed by subjects in the area of discomfort. It will be measured by a Visual Analogue Scale, meaning a score of 0 points/centimiters "no pain" and a score of 10 points/centimiters "unbearable pain".
Secondary Outcomes
- Neck disability index.(Pre treatment at the beginning of the study and one month later, on the last of the follow up period.)
- kinesiofobia(Pre treatment at the beginning of the study and one month later, on the last of the follow up period.)
- Pressure pain threshold(Changes on pain will be assessed during one month follow up. Baseline will be measured on the first day and one month later pain score will be reassessed.)
