Loss of balance leads to increased likelihood of falling for human locomotion. Determining the likelihood of falling for skiing locomotion is challenging because, unlike walking, normal locomotion is not clearly defined. One of the first learned styles of skiing is wedge style (WS). WS affords relatively easier balancing and speed control due to a wide base of support and greater resistance to forward movement, respectively. As skiers become more familiar with WS, their sensory, cognition, and actuation improve and they are able to apply more advanced styles, namely parallel style (PS), which requires refined balance. This paper studies the effects of WS and PS, on a single subject pilot study, and how they effect the likelihood of falling. A traditional laboratory setting was not suitable because of extreme difficulty and expense required to mimic the environment. Specially designed instrumented insoles were used to capture force data in a mountain environment.
平衡丧失会增加人类行走时摔倒的可能性。确定滑雪运动中摔倒的可能性具有挑战性，因为与行走不同，正常的滑雪运动没有明确的定义。最早学会的滑雪方式之一是楔形滑雪（WS）。由于支撑面宽和对向前运动的阻力较大，楔形滑雪分别提供了相对更容易的平衡和速度控制。随着滑雪者对楔形滑雪越来越熟悉，他们的感官、认知和驱动能力得到提高，并且能够应用更高级的滑雪方式，即平行式滑雪（PS），这需要更精细的平衡。本文在一项单受试者初步研究中，研究了楔形滑雪和平行式滑雪的效果，以及它们如何影响摔倒的可能性。由于模拟环境需要极大的难度和费用，传统的实验室环境并不适用。在山区环境中，使用专门设计的仪器化鞋垫来采集力数据。
