背景：下肢假肢使用者通常会在一天中经历残肢体积损失，这可能会对接受腔贴合产生不利影响。目的：确定暂时脱下假肢是否会促进残肢液体体积恢复以及是否维持回收的液体。研究设计：实验设计。方法：在每次三个测试阶段对 16 名参与者的残肢液体体积进行监测。参与者进行了六个休息/站立/行走循环。在第三个和第四个周期之间，参与者佩戴假体和内衬坐 30 分钟：戴上 (ON)、脱下假体但戴上内衬 (LINER)，或脱下假体和内衬 (OFF)。 结果：液体容量增加和保留百分比在 OFF 条件下最大，其次是 LINER 条件。参与者在 ON 情况下经历了体液容量损失。结论：与佩戴假体和内衬相比，在休息期间摘下假肢或假体和内衬可改善残肢体液容量保留。临床相关性医生应建议每日肢体容量损失较多的患者考虑暂时脱下假肢。如果假体和衬垫都脱落，则后续活动期间的液体容量保留将最高。
Background: Lower-limb prosthesis users typically experience residual limb volume losses over the course of the day that can detrimentally affect socket fit.Objectives: To determine whether temporarily doffing the prosthesis encouraged residual limb fluid volume recovery and whether the recovered fluid was maintained.Study Design: Experimental design.Methods: Residual limb fluid volume was monitored on 16 participants in three test sessions each. Participants conducted six cycles of resting/standing/walking. Between the third and fourth cycles, participants sat for 30min with the prosthesis and liner: donned (ON), the prosthesis doffed but the liner donned (LINER), or the prosthesis and liner doffed (OFF).Results: Percentage fluid volume gain and retention were greatest for the OFF condition followed by the LINER condition. Participants experienced fluid volume losses for the ON condition.Conclusion: Doffing the prosthesis or both the prosthesis and liner during rest improved residual limb fluid volume retention compared with leaving the prosthesis and liner donned.Clinical relevance Practitioners should advise patients who undergo high daily limb volume losses to consider temporarily doffing their prosthesis. Fluid volume retention during subsequent activity will be highest if both the prosthesis and liner are doffed.
