Objective To design a foot-drop-prevention holder for paralysis patients , to prevent patients from long-term foot-drop causing limbs disuse atrophy , effecting function recovery , and to discuss the rehabilitation effect of patients .Methods The foot-drop-prevention holder included a lower limb placing and T-shaped groove , and sponge covering the T-shaped groove .Fifty-five patients were selected from neurology department as the experimental group , placed foot-drop-prevention holder .Another fifty-three patients were not given foot-drop-prevention holder and selected as the control group .Maryland foot function score and short form Fugl-Meyer movement function score of lower limbs in the two groups were compared .Results Before the intervention, there was no significant difference between the two groups ( P >0.05).After one month of intervention, Maryland foot function scores were (90.85 ±3.02) of the experimental group and (83.50 ±2.43) of the control group.The difference was statistically significant (t=12.52, P<0.05).The short form Fugl-Meyer movement function scores were (30.90 ±2.14) of the experimental group and (22.13 ±2.26) of the control group.The difference was statistically significant (t=19.75, P<0.05).Conclusions The foot-drop-prevention holder is beneficial to rehabilitation of patients ’ lower limbs function , and can effectively replace nursing staff manual fixing .It is suitable for neurology patients .%目的：为肢体瘫痪患者设计防足下垂固定装置，以防止患者长期足下垂引起肢体废用性萎缩，并探讨其对患者的康复效果。方法防足下垂固定器由放置下肢及足部的T型凹槽及覆盖在上面的海绵两部分组成。将108例下肢瘫痪患者按照随机数字表法随机分为对照组53例和研究组55例，对照组患者按常规护理，研究组患者在常规护理基础上使用防足下垂固定器。1个月后比较两组患者的Maryland足部功能评分和下肢简式Fugl-Meyer运动功能评分（仰卧位）。结果治疗前，两组Maryland足部功能评分和Fugl-Meyer 运动功能评分差异均无统计学意义（ P＞0．05）。治疗1个月后，研究组Maryland足部功能评分为（90．85±3．02）分，对照组为（83．50±2．43）分，差异有统计学意义（t＝12．52， P＜0．05）；研究组下肢简式Fugl-Meyer运动功能评分为（30．90±2．14）分，对照组为（22．13±2．26）分，差异有统计学意义（t＝19．75，P＜0．05）。结论防足下垂固定器有利于患者下肢功能康复，可有效替代护理人员手工固定，适合下肢瘫痪患者使用。
