The Role of the Deep Cervical Extensor Muscles in Multi-Directional Isometric Neck Strength - Associated Model and Code

The purpose of this study was to determine the effects of deep cervical extensor muscle (multifidus and semispinalis cervicis) weakness on multi-directional neck strength and muscle activation patterns. Maximum isometric forces and associated muscle activation patterns were computed in 25 test directions using a 3-joint, 24-muscle musculoskeletal model of the head and neck. Our computational approach accounted for the differential torques about the upper and lower cervical spine. The manuscript associated with this data has been accepted for publication in the Journal of Biomechanics.
