Lower Limb Bilateral Amputee Model
A musculoskeletal model has been developed to estimate the muscle and joint contact forces in the lower residual limbs of a bilateral amputee during everyday activities. The model was developed in Opensim (Delp et al., 2007) based on the lower-body MRI scans of a single subject who lives with one above-knee and one through-knee amputation. The model has been adapted from the existing lower-limb model published by Modenese et al. (2011), with the insertions of certain muscles adapted to reflect re-attachments made during the subject’s amputation.
The model has been used to estimate muscle forces and joint contact forces in the lower limbs and pelvis during amputee gait, stair-climbing and sitting. These results will be used to create a physiologically accurate loading scenario for future Finite Element Analyses on amputee biomechanics.
