摘要:
基于人体运动协同控制理论提出人体爬行过程中四肢关节的协同运动模式与步行过程中四肢协同运动模式具有相似性是其能促进步行功能康复重要运动生理基础的假设。为了证明该假设，本研究首先基于MPU9250加速度传感器收集了5名受试者爬行和步行过程中双侧肘、腕、膝、踝关节等8处关节在运动过程中的加速度信号；然后，依次对信号进行预处理、周期分割、矢量化等处理；最后，利用非负矩阵分解算法提取爬行和步行运动过程中肢体间多关节运动的协同运动模式，并计算爬行与步行运动关节协同模式之间的相关系数。结果显示5名受试者爬行及步行过程中均能提取2种关节姿势协同模式，并且对应协同模式的相似系数分别为0.76和0.72，说明爬行运动与步行运动过程中肢体运动协同模式具有一定的相似性。本研究可以为爬行运动用于儿童步行功能康复提供一定的参考。
Abstract:
Abstract: Based on the coordinated control theory of human motion, a hypothesis that the similarity between the inter-joint synergies during crawling and walking is an important physiological basis for the promotion of walking rehabilitation by crawling is given and proved. The acceleration signals of 8 joints, including bilateral elbow, wrist, knee and ankle joints, in 5 subjects during crawling and walking are collected using MPU9250 accelerometer. After signals preprocessing, period segmentation and vectorization, the non-negative matrix factorization algorithm is used to extract the inter-joint synergies of the limbs during crawling and walking, and the correlation coefficients between the inter-joint synergies during crawling and walking are calculated. The results show that two inter-joint synergy patterns can be extracted from 5 subjects during crawling and walking, and that the corresponding correlation coefficients are 0.76 and 0.72, which indicates that the inter-joint synergies during crawling and walking are similar. The study provides some reference for the application of crawling in childrens walking rehabilitation.
