我们对人类行走了解甚多，但不知道在典型活动中如何使用行走。由于改善步行能力是许多外科、药理学和物理治疗干预的关键目标，了解典型的社区活动需求，包括步行回合的长度、经常进行的连续步数以及常见的非步行（休息）行为的持续时间似乎是明智的。本研究记录了10名非残疾受雇成年人的日常生活步态，以确定步行时间、连续步数和休息时间的长度，为期2周。受试者佩戴了一个StepWatch （TM）活动监测器（OrthoCare Innovations; Mountlake Terrace, Washington），该监测器在每10秒的时间窗口内计算步数。自定义代码总结了连续的步骤、行走行为的周期（回合）和没有步骤的周期（休息）。60%的步行比赛只持续30秒或更短；一场2分钟的步行比赛只占所有步行比赛的1%。在所有的步行比赛中，40%的比赛是连续走不到12步，75%的比赛是连续走不到40步。休息时间主要很短，一半的休息时间持续20秒或更短。非残疾就业成人的社区移动需求似乎包括频繁的短时间步行行为和许多短时间的非步行（休息）行为。
Much is known about human walking, but it is not known how walking is used during typical activities. Since improving walking ability is a key goal in many Surgical, phamacological, and physiotherapeutic interventions, understanding typical community mobility demands regarding the length of walking bouts, the number of sequential steps frequently performed, and the duration of common nonwalking (rest) behavior seems prudent. This study documents the gait of daily living in 10 nondisabled employed adults to define walking bout duration, sequential step counts, and length of rest periods over a 2-week period. Subjects wore a StepWatch (TM) Activity Monitor (OrthoCare Innovations; Mountlake Terrace, Washington) that counted steps in each 10-second time window. Custom code summed sequential steps, periods of walking behavior (bouts), and periods without steps (rest). Sixty percent of all walking bouts lasted just 30 seconds or less; a 2-minute walking bout was just I percent of total walking bouts. Forty percent of all walking bouts were less than 12 steps in a row, and 75 percent of all walking bouts were less than 40 steps in a row. Rest periods were predominantly very short, with half of all rests periods lasting 20 seconds or less. The Community mobility demand for nondisabled employed adults appears to involve frequent short-duration walking behavior with low numbers of sequential steps strung together and many short-duration nonwalking (rest) behaviors.
