Objective.定义从坐到走的运动阶段，并在正常人群中测试其一致性。一项对13名健康志愿者的观察性研究。从坐着到走路是一项日常活动，对于某些人群来说，在控制和稳定性方面可能存在困难。根据地面反作用力和全身质心峰值速度的变化，将运动划分为不同的阶段。每个阶段持续时间的一致性进行了评估。定义了从坐到走的四个阶段：屈曲动量、伸展、卸载和站立。ICC评分的阶段持续时间范围为0.54（伸展）至0.81（站立）。这是第一个定义从坐到走运动的不同阶段的研究。阶段持续时间具有中度至良好的一致性。
Objective. To define phases of the sit-to-walk movement and test their consistency in a normal population.Design. An observational study of thirteen healthy volunteers.Background. Moving from sitting to walking is a daily activity that may present difficulty for some populations in terms of control and stability.Methods. The movement was partitioned into phases according to changes in ground reaction forces and peak velocity of the total body centre of mass. Consistency of each phase duration was assessed.Results. Four phases of sit-to-walk were defined; flexion momentum, extension, unloading and stance. ICC scores for phase duration ranged from 0.54 (extension) to 0.81 (stance).Conclusions. This is the first study to define distinct phases of the sit-to-walk movement. There was moderate to good consistency for phase duration.
