Abstract: A Systems-Level Evaluation of the Biomechanical Response of the Cervical  Spine to Sagittal Plane Flexion

Neck pain and discomfort is a prevalent problem among surgeons. Previous studies have shown that there is a correlation between surgeons’ neck pain and their neck postural exposure during surgeries. How much do we know about this correlation and what can we do to mitigate the risk of neck pain and discomfort due to neck postural exposure? As the first step, a systematic review of the literature was conducted and two research questions were identified. 1) What are the effects of different work-rest cycles on neck muscle fatigue during static neck flexion tasks? The main goal was to investigate the impact of varied work-rest intervals and how they can affect the development of neck muscular fatigue (evaluated using surface electromyography (sEMG)) during a standing task that required static neck flexion. 2) What role do the passive tissues (e.g., ligaments) play in the support of the head/neck during flexion postures? The focus was to perform a systems-level evaluation of the biomechanical response of the cervical spine to sagittal plane flexion. Specifically, this part of the study explored the biomechanical difference between neck flexion relative to trunk and neck flexion relative to gravity.

The second part of this talk will focus on the applications of our findings to enhance current work assessment tools. Also, some of the ergonomic interventions that are being evaluated at Mayo Clinic to mitigate the risk of neck pain and discomfort among surgeons will be briefly reviewed.
