Biomechanical Analysis of Gait in Forestry Environments: Implications for Movement Stability and Safety

Walking through forests poses unique challenges due to uneven terrain. There are several different Gait studies investigating conditions of human movement, in urban, laboratory, or other terrain simulations. This study examines how people adjust their gait when moving across solid surfaces, forest trails, and natural forest environments. Utilizing the digital Xsens MVN Awinda motion capture system using precise IMU units, data were collected from 15 participants across 150 walking trials. Gait analysis key findings revealed that gait parameters, including step length, cadence, and foot strike variability, were significantly influenced by terrain type. Uneven forestry surfaces resulted in increased step width, reduced cadence, and heightened center of mass variability, reflecting adaptive strategies to maintain stability and reduce fall risk. These biomechanical changes highlight the body's efforts to maintain balance in challenging terrains. The study findings offer valuable implications for improving mobility and reducing fall risks in forestry work activities. Understanding these changes can help design better safety measures for navigating complex outdoor environments.
