护理干预对大鼠脊髓损伤后运动功能修复的影响

目的探索护理干预对脊髓损伤大鼠运动功能恢复程度的影响。方法将60只大鼠随机分为A、B、C共3个组(每组20只),A组为正常对照组,B组为实验对照组,C组为实验组;B组给予常规护理,C组在给予常规护理的基础上给予肌肉按压、关节被动运动、皮肤护理等护理干预。应用BBB评分和斜坡试验评价大鼠脊髓损伤后不同时相点的行为学变化,采用多道生理信号采集系统和电子天平称量,观察大鼠腓肠肌在脊髓损伤后不同时间点肌电反应和肌湿重变化。结果 BBB评分和斜坡试验结果基本一致,C组与B组相比,C组大鼠后肢功能明显改善,但与A组(正常对照组)相比,其后肢功能评分相差很大;腓肠肌肌电反应纤颤电位波幅C组较B组高;腓肠肌湿重下降C组较B组减轻。结论护理干预可延缓肌肉萎缩速度、改善运动功能,促进损伤脊髓功能的部分运动功能恢复。

Effect of nursing intervention on motor function recovery after spinal cord injury in rats

Objective To explore the effect of nursing intervention on degree of motor function recovery after spinal cord injury in rats. Methods 60 rats were randomly divided into three groups with 20 rats in each group. Group A was the control group, group B was the rou- tine nursing group, and group C was the nursing intervention group which was given nursing intervention such as muscle pressure,joint passive movement,and skin care. The ethology was evaluated by BBB score and inclined-plane score at different time points after spinal cord injury. Myoelectricity and wet weight of gastrocnemius muscle were observed at different time points after spinal cord injury through multi-channel physiological signal acquisition system and electronic weighing scMes. Results BBB score and inclined-plane score were basically the same. Compared with group B, hind limb function of group C was significantly improved, but it was obviously lower than the control group. Amplitude of gastrocnemius myoelectrical fibrillation in group C was higher than that in group B and gastrocnemius muscle wet weight decrease in group C was lower than that in group B. Conclusion Nursing intervention can delay the speed of gastrocnemius muscle atrophy, improve motor function, and promote the recovery of partial function after the spinal cord injury in rats.
