防足下垂牵引装置的设计及应用

目的探讨防足下垂牵引装置在预防长期卧床伴下肢主动运动功能缺陷患者足下垂中的作用。方法采用治疗型的弹力袜、弹性绷带、羊羔毛、软魔术贴等材料，制作预防足下垂的装置并应用于临床。结果18例采用防足下垂牵引装置患者在住院期间未发生1例足下垂。人院时患者肢体功能评分为（56．78±16．45）分，出院时为（66．11±9．89）分，入院时和出院时比较，t=一2．06，P〈0．05，差异具有统计学意义。结论防足下垂牵引装置可预防长期卧床伴下肢主动运动功能缺陷患者足下垂的发生，而且使用方便，值得临床推广应用。

Design and use of a device for prevention of foot drop

Objective To design a device for prevention of foot drop and explore the effects. Method A device was designed and made using elastic sock, elastic bandage and wools to prevent foot drops in 18 patients in bed for long term combined with motion functional deficit in lower limbs. Result None of the 18 patients contracted with foot drop, with limb function score of（66.11 ＋ 9.89）. There was statistical difference between discharge and admission （P 〈 0.05）. Conclusions The self-designed device is effective in the prevention of foot drop in the patients sleep in bed for long term combined with motion function deficits in lower limbs. It is easy and useful for the enhancement of the function of their limbs.
