摘要: 目的 探索在使用MOTOmed康复训练器训练时,患者身高、座椅高度、距离、曲柄长度及运行速度等因素对康复效果的影响。方法 将人体下肢简化成杆件模型。以膝关节角运动为因变量,运用控制变量法探讨个体身高、座椅距离(S)、座椅高度(H)、曲柄长度(L1)及运行速度( ω1 )等因素对康复效果的影响,并用MATLAB进行仿真分析。结果 固定个体身高,其他各因素对膝关节角位移、角速度、角加速度初始值及末尾值均有较大的影响,其中 L1对膝关节活动度的影响最大,S次之,H最小; ω1主要影响膝关节角速度和角加速度。固定 S=550 mm,H=165 mm,L1=180 mm, ω1 =10 r/s,身高越高,膝关节活动范围、角速度、角加速度越小。结论 不同身高个体在不同康复阶段,需对 MOTOmed康复训练器的座椅高度、距离,曲柄长度及运行速度等因素进行调节。

Abstract: Objective To explore the factors associated with the rehabilitation outcome of lower limbs training with MOTOmed, such as the height and distance of seats, the crank length and the speed, as well as the height of patients. Methods The human lower limb model was simplified into a model of the bars. The activity of knee was as a dependent variable, and the individual body height, distance (S) and height (H) of seats, the crank length (L1) and speed ( ω1 ) were as the independent variables, and analysed with control variate method and MATLAB simulation analysis. Results Controlling the individual body height, all the other factors influenced the knee joint angle, angular velocity and angular acceleration value (initial or the end value). Among these factors, L1 impacted the mobility mostly, and less as S and H; ω1 mainly impacted the angular velocity and acceleration. Controlling the other factors as S=550 mm, H=165 mm, L1=180 mm, ω1 =10 r/s, the higher the body height would be, the less the knee joint activities, angular velocity and angular acceleration are. Conclusion It is necessary to adjust the height and distance of seats, crank length and the speed to meet the individual body height when training with MOTOmed for lower limbs rehabilitation.
