An interventional study of Low frequency and High frequency in Neck Pain, Chronic Pain and Myofascial Pain Syndrome, sponsored by Centro Universitario La Salle. Completed at 1 site in Spain. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2018-05-09.
Sponsored by Centro Universitario La Salle · Not applicable, Interventional, and Treatment
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.
Exclusion Criteria:
Percutaneous electrical nerve stimulation with frequency of 2 Hz and 120 microseconds of pulse width will be applied.
Procedure: Low frequency
Percutaneous electrical nerve stimulation with frequency of 120 Hz and 200 microseconds of pulse width will be applied.
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 low frequency TENS is applied, at 2 Hz frequency and 120 microseconds of pulse width.

Pain
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".
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.
Pressure pain threshold
Minimal amount of pressure that induces pain. An algometer will be used to measure pressure pain threshold. Units will be kilograms per square centimeter. The higher the score is, the less sensitive the area will be.
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.
Neck disability index.
Ten items questionnaire designed to asses the level of pain and self-assessment of cervical disability. The NDI (Spanish version) is composed of 10 questions related to daily functional activities. NDI presents an acceptable reliability with an intraclass correlation coeffcient (ICC) ranging from 0.50 to 0.98. It has been proposed that the clinically important difference required for NDI is seven points.
Time frame: Pre treatment at the beginning of the study and one month later, on the last of the follow up period.
kinesiofobia
Eleven items questionnaire designed to asses pain-related fear. TSK-11, Spanish version.
Time frame: Pre treatment at the beginning of the study and one month later, on the last of the follow up period.
Plan to share: No — Data collected will be used only for research objective. Once the trial have finished, data will be destroyed.
