To investigate in a pilot study the use of extended walking times as an objective method of distinguishing differences in outcome in lower limb amputees.
Sixteen lower limb amputees attending the prosthetic clinic.
Patients were asked to walk 100 m, turning every 20 m, using their usual walking aids and prostheses at their chosen walking speed. Demographic details and modified Stanmore/Harold Wood mobility grades, walking aids used and discomfort were recorded. Time to walk each 20 m up to 100 m was recorded. Statistical analysis was carried out using the Spearman rank order correlation coefficient.
There was a wide age range and differing causes of amputation. Five out of 16 subjects failed to complete 100 m and these had the slowest 20- and 40-m times. The mean time to walk 40 m was 41 seconds for those who were able to complete 100 m and 144 seconds for those who could not complete 100 m. All those with modified Stanmore/Harold Wood mobility grades less than four failed to complete 100 m. There was a high correlation between 20-, 40-, 60-, 80- and 100-m times and mobility grades, which was statistically significant, and between 20-, 40-, 60-, 80- and 100-m times.
Forty-metre walking time can differentiate between those of mobility grades 4b-6 and those with lower mobility grades who are unable to walk significantly outside.
在一项初步研究中，调查使用延长步行时间作为区分下肢截肢者结局差异的客观方法。
16名下肢截肢者前往假肢诊所就诊。
要求患者使用其常用的助行器和假肢，以其选择的步行速度行走100米，每20米转弯一次。记录人口统计学细节、改良的斯坦莫尔/哈罗德·伍德活动等级、使用的助行器和不适感。记录每20米直至100米的步行时间。使用斯皮尔曼等级相关系数进行统计分析。
年龄范围广泛，截肢原因各不相同。16名受试者中有5人未能完成100米行走，这些人20米和40米的行走时间最慢。能够完成100米行走的人步行40米的平均时间为41秒，而无法完成100米行走的人则为144秒。所有改良的斯坦莫尔/哈罗德·伍德活动等级低于4级的人都未能完成100米行走。20米、40米、60米、80米和100米的行走时间与活动等级之间存在高度相关性，具有统计学意义，且20米、40米、60米、80米和100米的行走时间之间也存在相关性。
40米步行时间可以区分活动等级为4b - 6级的人与活动等级较低且无法在室外显著行走的人。
