Brief summary
This study evaluates whether a single session of percussion therapy can reduce muscle tension and increase blood flow in the transverse cervical artery in individuals with neck pain. The investigators will evaluate muscle stiffness using ultrasound elastography, and assess blood flow in the transverse cervical artery via Doppler imaging before and after treatment. The primary objective is to determine how this therapy affects neck muscle relaxation and vascular responses, specifically within the upper trapezius region.
Interventions
Theragun device applied to dominant side of upper trapezius muscle. Session duration: 3 minutes.
Longitudinal stripping massage of dominant side of upper trapezius muscle. Session duration: 3 minutes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Neck pain intensity on Visual Analog Scale (VAS) | Baseline, 20 minutes post-therapy, 2 days post-therapy (follow-up), immediately before next therapy session, 20 minutes post-second therapy, and 2 days post-second therapy (final follow-up) | Neck pain intensity evaluated using a Visual Analog Scale slide scale (score range 0-10, where 0 = no pain and 10 = worst imaginable pain). The patient marks their pain level using the slider, and the result is recorded as a numerical score. Unit of Measure: points |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Neck pain-related disability on Neck Disability Index (NDI) | Baseline, 2 days post-therapy (follow-up), immediately before next therapy session, and 2 days post-second therapy (final follow-up) | Neck pain-related disability measured with the Neck Disability Index (score range 0-50 points, where higher scores indicate greater disability). Unit of Measure: points |
| Shear-wave elastography of upper trapezius muscle: mean stiffness | Baseline, 20 minutes post-therapy, 2 days post-therapy (follow-up), immediately before next therapy session, 20 minutes post-second therapy, and 2 days post-second therapy (final follow-up) | Ultrasound shear-wave elastography of the upper trapezius muscle at the midpoint (foramen magnum-acromion line) to evaluate the mean stiffness value. Measurements performed supine with head stabilized, arms alongside body, cervical spine neutral. Probe placed at the midpoint of the trapezius. Ultrasound gel applied for optimal contact. The measurement is performed 3 times and the average value is used; repeated if discrepancies. Same researcher throughout. Unit of Measure: kilopascals (kPa) |
