Migraine is a significant health problem due to its high prevalence and substantial contribution to disability. Individuals with migraine have been reported to exhibit myofascial trigger points, increased pain sensitivity, and altered muscle activation patterns, particularly in the trapezius muscles. As the upper and middle trapezius muscles play critical roles in scapular stability and movement, alterations in these muscles may affect scapular orientation and upper extremity function. However, studies investigating the relationship between trapezius muscle activation, scapular orientation, and upper extremity performance in individuals with migraine are limited. Therefore, this study aimed to compare trapezius muscle activation, scapular orientation, and upper extremity performance between individuals with and without migraine. We hypothesized that individuals with migraine would exhibit altered upper and middle trapezius muscle activation, impaired scapular orientation, and reduced upper extremity performance compared with healthy controls.

Primary outcome measure(s)
Trapezius muscle activity — Single assessment at baseline Upper and middle trapezius muscle activations will be assessed on the dominant side using surface electromyography (sEMG). Following skin preparation, EMG sensors will be placed over the upper and middle trapezius muscles according to the recommendations of the Surface Electromyography for the Non-Invasive Assessment of Muscles (SENIAM). Resting muscle activity will be recorded prior to measurements to ensure signal quality. Muscle activations will first be recorded during maximal voluntary isometric contraction (MVIC) and subsequently during arm elevation in the scapular plane. EMG data will be analyzed using EMGworks software; signals will be filtered, processed using the root mean square (RMS) method, and normalized to each participant's MVIC values, expressed as %MVIC. Additionally, upper trapezius/middle trapezius activation ratios will be calculated, and muscle activation levels will be categorized according to predefined threshold values.
