Overview
Currently, no previous studies have investigated how the position of a muscle before dry needling may influence the outcome and effectiveness of the treatment.
This study aims to demonstrate whether the position of the upper trapezius muscle during dry needling treatment influences the outcome of that treatment in subjects with neck pain.
A total of 46 participants with chronic neck pain will be recruited and randomly assigned to two groups: a dry needling group with the muscle in a stretched position and a dry needling group with the muscle in a shortened position. A total of two treatment sessions will be performed, separated by a 7-day interval. The primary outcome measure will be the intensity of neck and head pain, measured using the visual analog scale (VAS). Other variables to be measured include the cervical disability index, kinesiophobia, and catastrophizing (using a self-completion questionnaire), as well as participants' expectations and post-needling pain.
