Effects of Neutral Postures on Mechanical Properties of Cervical Spine Under Different Gravitational Environments: A Musculoskeletal Model Study.

ABSTRACT: This study used the Anybody musculoskeletal model to investigate the effects of different neutral postures on the cervical spine and its associated muscle mechanical properties in various gravitational environments. A full-body musculoskeletal model (male, height: 1.74 m, mass: 74 kg) from the AMMR database, developed using the Anybody Modeling System, was employed to perform a quantitative analysis of three postures, including the neutral body posture in microgravity (NBP 0G), the neutral body posture in normal gravity (NBP 1G), and the relaxed standing posture in microgravity (SM 0G). The results showed that, compared to the NBP 1G posture in a gravitational environment, adopting the NBP 0G posture in microgravity resulted in an average reduction of 76.6% in the compressive force of the
