In this study, a human motion computer model in a wheelchair was developed to evaluate the effectiveness of a headrest for disabled people traveling in a motor vehicle. The human model was composed of four rigid links and four masses. This model was characterized with muscle reflection defined by Hill's equation. A sudden start experiment by using a carriage on which a wheelchair was fixed with a subject was performed to obtain human muscle parameters and to evaluate the model. Volunteer subjects including disabled people participated in the experiment. The motion and muscle activity of a subject with a headrest was simulated by this model. The muscle reflection of disabled people was stronger than that of normal people in the case of not using a headrest. The result of computer simulation showed that a headrest is more important for disabled people than for normal people.
