Development and validation of a musculoskeletal human model to study crutch-assisted gait
| Resumo: | The main purpose of this work is to present and discuss the development and validation of an advanced musculoskeletal human model to study crutch-assisted gait. For that, a 3D multibody approach is utilized, which incorporates the kinematic chain of the human body, the muscle structure, as well as the key features of crutches. The connection between the crutches and the human model is modeled by imposing kinematic constraints to the pair handle-hand. Moreover, the interaction between the crutches and ground is modeled using a penalty contact formulation. The skeletal muscle model for the lower limbs is based on the well-established Hill solution. In addition, an experimental analysis, performed at the Lisbon Laboratory of Biomechanics, is carried out with all the above-mentioned human model characteristics. From the key results obtained, it can be concluded that crutches’ solutions are able to support different levels of load during assisted gaits. |
