Assessment of plantar pressure dynamics in firefighters carrying self-contained breathing apparatus: a computational approach to gait stability analysis.
Firefighters carrying self-contained breathing apparatus (SCBA) during training or firefighting may reduce gait stability and increase the risk of injury. Twelve firefighters participated in treadmill gait experiments while carrying SCBA. Multiscale entropy (MSE) and fused pressure region amplitude ratios were used to assess gait stability and pressure distribution. Results showed that as speed increased from 4.5 km/h to 6 km/h, pressure amplitude decreased by 14.65% in the forefoot region and increased by 14.12% in the hindfoot region. MSE showed increased gait complexity at 6 km/h and increased stability at 4.5 km/h. These findings provide insights for potential boot optimization.
期刊介绍：
The primary aims of Computer Methods in Biomechanics and Biomedical Engineering are to provide a means of communicating the advances being made in the areas of biomechanics and biomedical engineering and to stimulate interest in the continually emerging computer based technologies which are being applied in these multidisciplinary subjects. Computer Methods in Biomechanics and Biomedical Engineering will also provide a focus for the importance of integrating the disciplines of engineering with medical technology and clinical expertise. Such integration will have a major impact on health care in the future.
