本研究旨在探讨规定速度的台阶测验的信度及性别、年龄差异，并阐明有用的测验参数和速度。140名老年人和50名年轻人进行了敲击和踏步测试，与节拍器提供的克里思相匹配。这两种测试都涉及到受试者用右手和左手或右腿和左腿在指定位置触摸纸张的动作。评价参数是在两个测试中蜂鸣声和片材被接触的时间之间的时间差以及在台阶测试中的双腿支撑和单腿支撑时间。两项试验中参数的试验间可靠性较高。老年人中两种40 bpm测试的时间差异男性大于女性。在台阶试验中，老年人的时间差和两条腿支撑时间较大，依次为40、60和120 bpm，单腿支撑时间在40 bpm小于60 bpm或120 bpm。年轻受试者的单腿支撑时间较大，约为40、60和120 bpm。在40 bpm和60 bpm测试中发现了显著的年龄相关差异，并且老年人的时间差和两条腿支撑时间较大，而年轻受试者的单腿支撑时间较大。老年人在40 bpm时的时间差在台阶试验中比在敲击试验中大。在年轻受试者中，两种测试之间没有显著差异。总之，慢速台阶试验，因为它需要一个长的单腿支撑阶段，是有效的评估老年人的动态平衡。时间差、单腿支撑和双腿支撑次数是台阶试验的有效评价参数。
This study aimed to examine the reliability and sex- and age-related differences of step tests with stipulated tempos as well as to clarify useful test parameters and,tempos. One hundred forty elderly people and fifty young adults conducted tapping and stepping tests, matching the tempo provided by a metronome. Both tests involve movements where the subject touches a sheet with both the right and left hands or right and left legs at a designated spot. Evaluation parameters were the time difference between the beep sound and the time at which the sheet was touched in both tests as well as two-leg support and one-leg support times in the step test. The trial-to-trial reliability of the parameters in both tests was high. The time differences of both 40 bpm tests in the elderly were larger in males than in females. In the step test, the time difference and two-leg support times of the elderly were larger, in the order of 40, 60, and 120 bpm, and the one-leg support time was less in 40 bpm than 60 bpm or 120 bpm. The one-leg support time of the young subjects was larger, in the order of 40, 60, and 120 bpm. A significant age-related difference was found in the 40 bpm and 60 bpm test, and the time difference and two-leg support time were larger in the elderly while the one-leg support time was larger in the young subjects. The time difference at 40 bpm in the elderly was larger in the step test than in the tap test. There was no significant difference between both tests in the young subjects. In conclusion, the step test with the slow tempo, because it requires a long one-leg support phase, is effective for evaluating dynamic balance in the elderly. The time difference and two-leg and one-leg support times are effective evaluation parameters of the step test.
