The gait pattern of five amputees was recorded by visual observation and also by a quantitative measurement system. The results were compared with the gait pattern predicted from biomechanical analysis. Visual observation was found to be an unreliable clinical skill. The observers recorded only 22.2% of the predicted gait deviations and were unable to comment on 15.6% of all the required observations. The gait parameters which were difficult to assess visually, namely step length and step time, are considered by most workers to be of particular value as diagnostic clinical indicators in gait assessment. The measurement system used was accurate in recording gait deviations and picked up 3.4 times as many deviations as visual observation. This report demonstrates the inadequacy of visual observation as a diagnostic method and emphasises the need for measurements.
通过视觉观察和定量测量系统记录了五名截肢者的步态模式。将结果与生物力学分析预测的步态模式进行了比较。发现视觉观察是一项不可靠的临床技能。观察者仅记录了预测步态偏差的22.2%，并且无法对所有所需观察结果的15.6%进行评论。大多数工作人员认为，视觉上难以评估的步态参数，即步长和步时，作为步态评估中的诊断临床指标具有特别的价值。所使用的测量系统在记录步态偏差方面很准确，检测到的偏差是视觉观察的3.4倍。本报告证明了视觉观察作为一种诊断方法的不足，并强调了测量的必要性。
