Inclusion criteria
* Age from 40 to 65 years old participated in this study, 2 * Having neck pain for more than 6 months with a grade five or greater on the visual analog scale * Having one or more trigger points in the upper trapezius muscle, * A significant increase in neck muscle EMG activity indicates the presence of tender points.
Exclusion criteria
* Taking non-pharmacological therapies (e.g., acupuncture, physical therapy, osteopathy) * Taking oral or intravenous pain therapy, intramuscular or subcutaneous injection of cortisone, or local anesthetics during the study period, * Presence of any contraindication to electrical current including pregnancy, epilepsy, cardiac arrhythmia, cardiac surgery, implanted pacemaker or defibrillator, previous surgery in the spinal cord, infectious diseases of the spinal cord, malignant tumors with or without secondary blastomas in the spinal cord, severe radicular pain with acute paralysis in the extremities
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain intensity | 2-3 months | Neck pain intensity will be assessed by the visual analog scale (VAS). Participants will be asked to explain their present pain by putting a mark on a 10 mm horizontal line with 0 degrees indicating no pain and 10 indicating the worst possible pain |
| Pressure threshold | 2-3 months | Myofascial trigger points' sensitivity will be measured by a pressure-pain algometer from upper trapezius muscle. |
| Electromyography | 2-3 months | The EMG activity from the upper trapezius muscle will be recorded during rest and voluntary maximum contraction. |
| Range of motion | 2-3 months | Flexion, lateral rotation to both sides, lateral flexion to both sides |
