Tissue‐Level Neck Response in Rotary‐Wing Aircrew With Head‐Supported Mass Assessed With Finite Element Model

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 5, May 2026.
Rotary‐wing aircrew have reported the occurrence of neck pain, potentially associated with rapid scanning tasks and head‐supported mass (HSM). The aim of this study is to gain additional insight into the interaction of HSM and neck positions with the innervated tissues in the neck.
