Computer-Based Estimation of Spine Loading during Self-Contained Breathing Apparatus Carriage
文献摘要：
Firefighters' low back disorders (LBDs) are closely related to excessive spine loading when using the self-contained breathing apparatus (SCBA) continuously. The purpose of this study was to quantify firefighters' spine loading and evaluate the effects of strap lengths of SCBA on altering spine loading. Computer-based musculoskeletal models of three varying-strapped SCBA conditions and a control condition (CC) with no SCBA equipped were developed. The model was driven using three-dimensional (3D) inertial motion capture data from twelve male subjects performing a walking task and the predicted ground reaction force (GRF). Electromyography (EMG) activities were also recorded to validate the results from the model. The 4th - 5th lumbar vertebra (L4/L5) joint reaction forces, as well as erector spinae and rectus abdominis forces, were finally obtained. Results demonstrated that carrying SCBA significantly increased the compressive force and anteroposterior shear force at the spine. The risk of potential LBDs increased by about 17.77％. Dynamic balance of erector spinae and rectus abdominis contraction was also disturbed when carrying SCBA, indicating a higher risk of spine muscle strain. Adjustment of SCBA strap length was an efficient method to influence spine loading. The medium-fitting strap (MS) with a length of around 101 cm generated minimum joint reaction forces and achieved the optimum dynamic balance of spine muscle contraction, which was recommended for firefighters.
