An isovelocity dynamometer method to determine monoarticular and biarticular muscle parameters

摘要: This study aimed to determine whether subject-specific individual muscle models for the ankle plantar flexors could be obtained from single joint isometric and isovelocity maximum torque measurements in combination with a model of flexion. Maximum flexion were taken on one subject at six knee angles spanning full extension. A planar three-segment (foot, shank thigh), two-muscle (soleus gastrocnemius) was developed. Seven parameters per determined by minimizing weighted root mean square difference (wRMSD) between output experimental data. Valid using data only two giving wRMSD score 16 N m, values ranging 11 17 m each angles. The robustness methodology confirmed through repeating optimization perturbed torques (±20%) segment lengths (±10%) r...
