摘　　要：介绍了一种基于优化和力—肌电关系的肌肉力混合计算方法,用于计算上肢屈曲运动中的肌肉力,并与传统优化方法和基于力—肌电关系的方法进行了比较。传统优化方法不能计算对抗肌的肌力值,基于力—肌电关系的计算结果不能满足力学平衡关系,基于优化和力—肌电关系的肌肉力混合计算方法克服了这两个缺点,但计算结果波动剧烈。目前,混合方法只适用于肌肉等长收缩和等动收缩的肌肉力计算。A hybrid method based on optimization and force-EMG relationships for predicting muscle force was presented and applied to the flexion movement of upper limb. The results were compared with those from classical optimization and from the method based on force-EMG relationships. The classical optimization can not predict the force of antagonistic muscles. The method based on force-EMG relationships can not satisfy the mechanical equilibrium. The hybrid method overcomes the two disadvantages, but the forces predicted by it fluctuate excessively. Now the hybrid method is just appropriate for use in predicting isometric and isokinetic movements.
