The purpose of this study is to develop a motor evaluation system for the lower limb using a sensor ergometer and a musculoskeletal model with the prospect that the system is used in rehabilitation and in general exercise institutions. To estimate joint angles from the pedal position, an inverse kinematics model was constructed, and the validity was investigated by comparing these values with those from a motion capture system. The muscle forces were calculated from the musculoskeletal model, and also compared with the filtered EMG patterns. Using the developed system, the effect of changing the saddle height on a mechanical load of the patellofemoral joint was discussed. As the results, the estimated joint angles agreed with those from the motion capture system with the accuracy of correlation coefficients of over 0.98, and the calculated muscle forces pointed to a trend to analogize with the EMG patterns. These results showed that the proposed system was valid. However, the relationship between the mechanical load of the patellofemoral joint and the saddle height was not found.
