Evaluation of effective alternative stepping and development of exercise program for avoiding falls in the elderly

本研究旨在发展一种避免跌倒的侧向交替踏步运动，并提出适合老年人的运动计划。侧向前伸运动后的交替步可分为滑步和交叉步。滑步表现为延迟反应，直到开始的步骤和姿势不稳定后的步骤。此外，参加滑步运动的老年人有跌倒的高风险。本研究提出了提高跨步能力的练习，并编制了四跨步测验，以检验其练习效果。建议通过5个月的运动干预，提高跨步能力。

This study aimed to develop test of alternative stepping as an avoiding fall movement to lateral direction and to propose exercise program for the elderly. The alternative step after lateral reach motion was classified slide step and crossover step. The slide step showed delay response until onset of step and postural instability after the step. In addition, the elderly who took slide step tended to have fall high risk. This study proposed the exercise to improve a cross over step ability, and developed Four Cross Step Test to examine its exercise effect. It is suggested the improvement of cross over step ability by the exercise intervention for five months.
