Improved Estimation of Human Neck Tensile Tolerance: Reducing the Range of Reported Tolerance Using Anthropometrically Correct Muscles and Optimized Physiologic Initial Conditions

Muscle forces are a function of the muscle's state of activation, geometry, and constitutive properties. Load bearing capabilities of neck muscles impact the tolerance of the human neck in tension. Computational modeling of the cervical spine is the best way to comprehend the influence of muscle on whole neck tolerance to tension. The authors obtained accurate three-dimensional muscle geometry for 23 pairs of cervical muscles from dissection of human cadavers and also from magnetic resonance images of 50th percentile male volunteers. They incorporated those muscles into a computational model of the ligamentous spine that has been previously validated. They developed techniques to provide quantitative estimates of load sharing between the ligamentous spine and neck muscles.
