Comparison of Thickness, Tension, and Activation of the Scm and Upper Trapezius Muscles According To The Pillow Height

Abstract

The study aimed to analyze the effect of pillow height on upper trapezius and sternocleidomastoid (SCM) muscle activity and overall human body comfort to determine the optimal pillow height. METHODS:The study included 32 healthy college students, of both genders, who provided prior consent. It examined three pillow heights (flat, 6cm, 12cm) and measured the upper trapezius and SCM muscles using ultrasonography, myotone, and electromyography(EMG).Muscle activation, thickness, and fatigue were assessed. RESULTS:The study found significant differences in muscle thickness and muscle tone based on the pillow heights
