Objectively monitored free-living physical behaviours of adults with and without lower limb amputation (LLA) were compared.
57 adults with LLA wore an activPAL3™ for 8 days. A comparison data set ( = 57) matched on gender, age and employment status was used. Variables included: time sitting; standing; stepping; sit-to-stand transitions; step count and cadence. Comparisons were made between adults with and without LLA and between gender, level and cause of amputation.
Participants with LLA due to trauma versus circulatory causes were less sedentary and more active; however, no difference in physical behaviour was recorded across gender or level of amputation. Participants with LLA spent more time sitting ( < 0.001), less time standing and stepping ( < 0.001) and had a lower step count ( < 0.001). Participants with LLA took more steps in cadence bands less than 100 steps·min and fewer steps in cadence bands greater than 100 steps·min compared to participants without LLA.
People with LLA were less active and more sedentary than people without LLA and participated in less activity at a moderate or higher intensity when matched on age, gender and employment. Interventions are needed to promote active lifestyles in this population.
目的：比较有和无下肢截肢（LLA）成年人的客观监测的自由生活体力行为。
方法：57 名有 LLA 的成年人佩戴 activPAL3™ 8 天。使用性别、年龄和就业状况相匹配的对照数据集（n=57）。变量包括：坐着时间；站立时间；行走时间；从坐到站的转换次数；步数和步频。比较有和无 LLA 的成年人以及性别、截肢水平和原因之间的差异。
结果：与循环原因导致的创伤性 LLA 参与者相比，活动量较少，但在性别或截肢水平方面，体力行为没有差异。有 LLA 的参与者坐的时间更多（<0.001），站立和行走时间更少（<0.001），步数更少（<0.001）。与无 LLA 的参与者相比，LLA 参与者在步频小于 100 步·min 的步频带中行走的步数更多，在步频大于 100 步·min 的步频带中行走的步数更少。
结论：与无 LLA 的参与者相比，有 LLA 的参与者活动量较少，久坐时间更多，在匹配年龄、性别和就业状况的情况下，中等或更高强度的活动量较少。需要干预措施来促进这一人群的积极生活方式。
