摘要
背景:足位和座椅高度是影响“坐-站转移”的重要因素,但目前对“坐-站转移”动作的研究多侧重于健康人群和帕金森患者,痉挛型脑瘫儿童在不同座椅高度和足部位置下执行“坐-站转移”任务中的下肢运动学和动力学特征尚未可知。目的:探究不同足部位置及座椅高度对脑瘫儿童执行“坐-站转移”任务过程中下肢运动学和动力学参数的影响。方法:选择7名痉挛型脑瘫儿童作为研究对象,对其进行6个任务即3种座椅高度(高、中、低凳)×2种足位(前、后足位)的“坐-站转移”动作测试,采集脑瘫儿童在不同足位和座椅高度下“坐-站转移”时的运动学和动力学数据。结果与结论:(1)时间特征结果表明,相较于低凳条件,脑瘫儿童在高凳条件下进行“坐-站转移”任务所需总时间显著减少(P=0.046);(2)动力学结果表明,抬离瞬间,双足后位条件下的膝关节屈曲力矩显著大于双足前位条件(P=0.049);相较于中凳条件,在高凳条件下膝关节屈曲力矩显著减小(P <0.001);(3)结果提示抬高座椅高度和改变足位条件均对痉挛型脑瘫儿童的“坐-站转移”表现有影响,在高凳双足后位条件下儿童使用较小的运动补偿就可以完成坐站动作;同时高座椅可作为痉挛型脑瘫儿童增强“坐-站转移”表现的辅助工具,高凳双足后位条件更有助于脑瘫儿童“坐-站转移”动作的完成。
BACKGROUND:Foot position and seat height are important factors affecting“Sit-to-Stand”,but most of the current research on“Sit-to-Stand”focuses on healthy people and Parkinson’s disease patients.The kinematic and kinetic characteristics of the lower limbs of children with spastic cerebral palsy during the“Sit-to-Stand”task under different foot positions and seat heights are not known.OBJECTIVE:To investigate the effects of different foot positions and different seat height on lower limb kinematic and kinetic parameters during the“Sit-to-Stand”task in children with cerebral palsy.METHODS:Seven children with spastic cerebral palsy were selected as the research subjects.All subjects received the“Sit-to-Stand”test of six tasks,namely three seat heights(high,medium,and low stools)×two foot positions(front and back foot positions).The kinematic and dynamic data of children with cerebral palsy were collected under different foot positions and seat heights.RESULTS AND CONCLUSION:(1)The time characteristics results showed that the total time required for the children with cerebral palsy to perform the sit-to-stand transfer task was significantly smaller in the high stool condition compared to the low stool condition(P=0.046).(2)The kinetic results showed that at the moment of lifting,the knee flexion moment was significantly larger in the bipedal posterior condition than the bipedal anterior condition(P=0.049).The knee flexion moment was significantly smaller in the high stool condition compared to the medium stool condition(P<0.001).(3)It is concluded that raising the seat height and changing the foot position had an effect on the sit-to-stand transfer in children with spastic cerebral palsy.The children were able to perform the sit-to-stand maneuver with less motor compensation in the high-stool bipedal-rear position condition.Meanwhile,the high chair can be used as an aid to enhance the performance of sit-to-stand transfer in children with spastic cerebral palsy.The high stool bipedal hindfoot condition was the most effective in improving the sit-to-stand transfer in children with spastic cerebral palsy.
