Falls from residential roofs account for 80% of roofing industry fatalities. Furthermore, roofing work represents 44.7% of work in residual construction specialty trades and residential roofers count for 2.1% of overall workers in construction, with an anticipated growth in roofers of 14.9% by 2024. The purpose of the study was to evaluate the alterations in spatiotemporal gait parameters while traversing along a 6/12 pitched residential roof segment. Eighteen of the nineteen calculated spatiotemporal variables were statistically, significantly changed by walking across a 6/12 pitched simulated residential roof. The study clearly demonstrates that spatiotemporal gait variables increase and decrease while traversing across a residential roof. The changes in spatiotemporal parameters might suggest alterations to a person's balance system resulting in an increased risk of falling. The knowledge generated in the current study will be relevant to the residential roofing industry when it can be used in educational materials to increase awareness of how a roofer's altered gait while working on a pitched roof may increase their falling risk.
住宅屋顶坠落事故占屋面行业死亡人数的80%。此外，屋面工程占剩余建筑专业行业工作量的44.7%，住宅屋面工占建筑行业总工人数量的2.1%，预计到2024年屋面工数量将增长14.9%。本研究的目的是评估沿着6/12坡度的住宅屋顶段行走时时空步态参数的变化。在19个计算出的时空变量中，有18个在走过6/12坡度的模拟住宅屋顶时发生了统计学上的显著变化。该研究清楚地表明，在穿过住宅屋顶时，时空步态变量会增加和减少。时空参数的变化可能表明一个人的平衡系统发生了改变，从而增加了跌倒的风险。当本研究产生的知识可用于教育材料，以提高对屋面工在斜屋顶上工作时步态改变如何增加其跌倒风险的认识时，将与住宅屋面行业相关。
