Study conducted to compare the accuracies of four-bar and five-bar link segment models used to predict semi-reclined leg cycling kinematics in people who have spinal cord injuries and who are able-bodied. Data were collected from a participant with a spinal cord injury and from a participant who was able-bodied. Joint kinematic data of participants’ hips, knees, and ankles were evaluated and compared between the experimental and the two types of models during pedaling on a standard ERGYS exercise bike. A video-based motion capture system from Peak Performance Technologies was used for motion evaluation. The accuracies of the four-bar and the five-bar models were obtained using root-mean-square statistical analyses. The authors concluded that both models tended to oversimplify lower limb kinematics. The five-bar model was viewed as a more valid tool in determining the kinematics of cycling for both participants.
