| 内容記述 | Sit-to-stand （STS） transition is one of the most bio-mechanically challenging task necessary for performing activities of daily life. With muscle strength being the most dominant, many co-occurring factors influence how individuals perform STS. This work investigated the STS changes and the STS failure caused by muscle strength deficits using the trajectories generated employing open-loop single shooting optimization and musculoskeletal models. It also presents the external assistance trajectories that can complement strength deficits for successful STS transition using the same framework. The muscle strength deficits were introduced by simultaneously scaling the maximum isometric strength of muscles in steps of 20%. The optimization could generate successful STS transition for models with up to 60% strength deficits. The joint angle, muscle activation and ground reaction force trajectories for the 0% strength deficit model’s STS transition agree with those experimentally observed for a healthy adult. Comparison of different strength deficit trajectories shows that when the vasti muscle gets saturated, the activation of antagonistic hamstrings muscles reduces to relieve it. The reduction in hamstring muscle activation subsequently increases the load on the gluteus maximus muscle. This adaptation and the motion tracking results are used to suggest the vastus muscle weakness to be responsible for STS breakdown. Finally, the successful STS trajectory generated for the externally assisted 80% strength deficit model is presented. The trajectory features utilization of external assistance as and when needed to complement strength deficits for successful STS transition. Our results will help plan intervention and design novel STS assistance devices. | |||||||
