The study purpose was to determine the minimum number of monitoring days necessary to reliably capture walking among individuals with lower limb salvage.
Nineteen participants with lower limb salvage wore an ankle-mounted motion sensor over a 7-day period to obtain step counts. Generalizability theory was used to examine the variance components in step counts (G study) and to determine the appropriate length of activity monitoring using various combinations of days (D study).
Mean step counts were higher on weekends than on weekdays. Fifty percent of the total variance in step counts was accounted for by interindividual variability in walking (D study). Eighty percent was reached individually with 4 weekdays, 2 weekend days, or 3 week days + weekend days.
The study provides data for an appropriate monitoring method to track walking outcomes of rehabilitation for individuals with lower limb salvage.
本研究旨在确定可靠捕捉下肢保肢患者步行情况所需的最少监测天数。
19名下肢保肢患者在7天时间内佩戴脚踝运动传感器以获取步数。采用通用izability理论来检查步数的方差成分（G研究），并使用不同天数组合来确定活动监测的合适时长（D研究）。
周末的平均步数高于工作日。步数总方差的50%由个体间步行差异所致（D研究）。分别在4个工作日、2个周末日或3个工作日加周末日时可达到80%。
本研究为追踪下肢保肢患者康复步行结果的合适监测方法提供了数据。
