Overview

In the planned study, we aim to investigate the effectiveness of percutaneous electrolysis treatment applied to myofascial trigger points in the upper trapezius muscle in patients with chronic neck pain. Two different protocols, a low-intensity (0.5 mA × 90 s) and a high-intensity (3 mA × 3 s × 3 repetitions), will be compared in the study.

Patients participating in the research will be randomized into 2 groups using a computer program. Stretching exercises targeting the upper trapezius muscle will be given to both groups as a home exercise program. In both groups, the percutaneous electrolysis treatment protocol will be performed on the active myofascial trigger points in the upper trapezius muscle on the 1st, 8th, and 14th days of treatment, using 0.3-millimeter acupuncture needles and an EPTE® percutaneous electrolysis device (Ionclinics \& A. Deionic SL, Valencia, Spain). The low-intensity (0.5 milliampere × 90 s) treatment protocol will be applied to Group 1, and the high-intensity (3 milliampere × 3 s × 3 repetitions) treatment protocol will be applied to Group 2. In the study, two different protocols, low-intensity (0.5 mA × 90 s) and high-intensity (3 mA × 3 s × 3 repetitions), will be compared. In this way, it is aimed both to obtain information about optimal dosing and to contribute to the literature for a frequently involved muscle such as the upper trapezius.
