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.
