目的：建立舒适和最大步态速度的参考值，并描述步态速度的措施和选定的变量与them.Design的相关性的可靠性：描述性和横截面。步态是在7.62米的地板上计时的。测定实际和高度归一化速度。结果：平均舒适步态速度范围为127.2厘米/秒的女性在他们的70岁到：146.2厘米/秒的男性在他们的40岁。平均最大步态速度范围为174.9 cm/s（70多岁女性）至253.3 cm/s（20多岁男性）。两种步态速度测量值都是可靠的（相关系数大于或等于0.903），并且与年龄（r大于或等于-0.210）、身高（r大于或等于0.220）和四种测量的下肢肌肉动作的强度（r=0.190-0.500）显著相关。肌肉动作强度最强烈相关的步态：速度是非显性髋关节外展（舒适的速度）和膝关节伸展（最大速度）。结论：这些规范值应该给临床医生一个参考：病人的表现可以在各种设置进行比较。在年龄较大、身高和下肢肌肉力量较小的个体中，预计步态速度会降低。
Objectives: to establish reference values for both comfortable and maximum gait speed and to describe the reliability of the gait speed measures and the correlation of selected variables with them.Design: descriptive and cross-sectional.Methods: subjects were 230 healthy volunteers. Gait was timed over a 7.62 m expanse of floor. Actual and height normalized speed were determined. Lower extremity muscle strength was measured with a hand-held dynamometer.Results: mean comfortable gait speed ranged from 127.2 cm/s for women in their seventies to: 146.2 cm/s for men in their forties. Mean maximum gait speed ranged from 174.9 cm/s for women in-their seventies to 253.3 cm/s for men in their twenties. Both gait speed measures were reliable (coefficients greater than or equal to 0.903) and correlated significantly with age (r greater than or equal to-0.210), height (r greater than or equal to 0.220) and the strengths of four measured lower extremity muscle actions (r=0.190-0.500). The muscle action strengths most strongly correlated with gait: speed were nondominant hip abduction (comfortable speed) and knee extension (maximum speed).Conclusions: these normative values should give clinicians a reference against which:patient performance can be compared in a variety of settings. Gait speed can be expected to be reduced in individuals of greater age and of lesser height and lower extremity muscle strength.
