这项研究的目的是调查经胫骨失去肢体的人在一天内残肢液体量的变化率。使用生物阻抗分析技术，对12名常规假体使用者进行每天两次的坐姿、站立和行走活动30min测试期间体液容量变化率的测量，一次在上午，一次在下午。在测试期间，所有受试者都食用食物和饮料，受试者的活动量从低到高不等。术中液体量变化率为-8.5%~5.9%/h(中位数：-2.2%/h)。治疗间歇液体量变化率为-2.7%~0.9%/h(中位数：-1.0%/h)。间歇液体量变化率与下午的间歇变化率高度相关(r=0.9)，而与上午的间歇变化率相关性不好(r=0.8)。有外周动脉并发症的受试者在测试过程中表现出比两次测试之间更大的液体容量丢失率。坐姿、站立和行走活动、存在外周动脉并发症、女性、截肢后的时间以及长时间佩戴插座而不脱毛可能会影响液体量的变化率。
The purpose of this research was to investigate rates of residual-limb fluid volume change within one day for people with transtibial limb loss. Rates of fluid volume change during 30 min test sessions of sitting, standing, and walking activities were measured twice a day, once in the morning and once in the afternoon, on 12 regular prosthesis users with the use of bioimpedance analysis. Between test sessions, all subjects consumed food and drink, and subject activity ranged from low to high. The rate of fluid volume change within sessions ranged from -8.5 to 5.9 %/h (median: -2.2 %/h). The rate of fluid volume change between sessions ranged from -2.7 to 0.9 %/h (median: -1.0 %/h). The between-session rate of fluid volume change correlated highly with afternoon within-session rates of change (r = 0.9) but was not well correlated with morning within-session rates of change (r = 0.8). Subjects with peripheral arterial complications showed greater fluid volume loss rates during test sessions than between sessions. Rate of fluid volume change may be affected by sitting, standing, and walking activities; presence of peripheral arterial complications; being female; time since amputation; and wearing the socket without doffing for extended periods.
