About this trial
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.

Treatment groups
Trial outcomes
Primary outcomes
Neck pain intensity on Visual Analog Scale (VAS)
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 outcomes
Neck pain-related disability on Neck Disability Index (NDI)
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
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)
Myotonometry of upper trapezius muscle: oscillation frequency
Assessment of myofascial tissue tone (oscillation frequency) of the upper trapezius at the midpoint (foramen magnum-acromion line) using MyotonPRO device. Measurements performed supine with head stabilized, arms alongside body, cervical spine neutral. Probe placed perpendicular to the muscle surface at the midpoint of the trapezius. Same researcher throughout. Unit of Measure: hertz (Hz)
Myotonometry of upper trapezius muscle: dynamic stiffness
Assessment of biomechanical properties (dynamic stiffness) of the upper trapezius at the midpoint (foramen magnum-acromion line) using MyotonPRO device. Measurements performed supine with head stabilized, arms alongside body, cervical spine neutral. Probe placed perpendicular to the muscle surface at the midpoint of the trapezius. Same researcher throughout. Unit of Measure: newtons per meter (N/m)
Other outcomes
Peak systolic velocity (Vs) of the transverse cervical artery.
Doppler ultrasound of the transverse cervical artery to evaluate Vs. Measurements performed supine with head stabilized, arms alongside body, cervical spine neutral. Probe positioned over the transverse cervical artery. Ultrasound gel applied for optimal contact. The measurement is performed 3 times and the mean value is used; repeated if discrepancies. Same researcher throughout. Unit of Measure: millimeters per second (mm/s)
End-diastolic velocity (Vd) of the transverse cervical artery.
Doppler ultrasound of the transverse cervical artery to evaluate Vd. Measurements performed supine with head stabilized, arms alongside body, cervical spine neutral. Probe positioned over the transverse cervical artery. Ultrasound gel applied for optimal contact. The measurement is performed 3 times and the mean value is used; repeated if discrepancies. Same researcher throughout. • Unit of Measure: millimeters per second (mm/s)
Resistive index (RI) of the transverse cervical artery.
Doppler ultrasound of the transverse cervical artery to evaluate RI. Measurements performed supine with head stabilized, arms alongside body, cervical spine neutral. Probe positioned over the transverse cervical artery. Ultrasound gel applied for optimal contact. The measurement is performed 3 times and the mean value is used; repeated if discrepancies. Same researcher throughout. • Unit of Measure: dimensionless (lub ratio / score)
