dc.description.abstractBackground: Chronic neck pain (CNP) is associated with altered muscle properties and pain sensitivity, especially in the trapezius muscle. However, evidence on how viscoelastic properties vary across different regions of the trapezius remains limited. Objective: This study aimed to compare the viscoelastic properties, pressure pain threshold, cervical range of motion, disability, depression, and perceived stress between individuals with CNP and asymptomatic controls. Methods: Twenty-six individuals with CNP (median age (IQR): 23 (22 – 24)) and 26 age- and sex-matched controls (median age (IQR): 23 (22 – 25)) were included. Muscle viscoelastic properties of the upper, middle, and lower trapezius were measured using the MyotonPRO. Pressure pain threshold was evaluated with a digital algometer, and cervical range of motion was assessed using a CROM device. Disability, depression, and perceived stress were measured using the Neck Disability Index, Beck Depression Inventory, and Perceived Stress Scale, respectively. Results: Individuals with CNP showed significantly increased muscle tone and stiffness in the upper trapezius bilaterally and altered viscoelastic properties in the middle trapezius (affected side). Pressure pain threshold values were significantly lower across all portions of trapezius. Despite these differences, no significant cervical range of motion limitations were found. Conclusion: Altered mechanical and sensory properties in the trapezius muscle — particularly in its upper and middle portions — may contribute to CNP, even in the absence of substantial cervical mobility limitations. This study provides the first comprehensive comparison of all three trapezius regions in individuals with CNP using handheld myotonometry, offering novel insights into the segment-specific mechanisms underlying chronic neck pain.
