چکیده
• MATLAB tool to apply lower limb rotational profiles generic musculoskeletal models. Dependency of joint loadings on femoral version angles was studied. Our results were assessed against in vivo knee (5th Grand Challenge data). Most accurate model predictions obtained with personalized version. Caution using models for patient-specific loading predictions. Musculoskeletal (MSK) based literature data are meant represent a anatomy and popular employed by biomechanists estimate the internal loads occurring joints, such as reaction forces (JRFs). However, since these normally just linearly scaled an individual’s anthropometry, it is unclear how their estimations would be affected personalization key features MSK anatomy, one which angle.

Ground reaction forces and lower-limb joint kinetics of turning gait in typically developing children.
Turning is a common locomotor task essential to daily activity; however, very little is known about the forces and moments responsible for the kinematic adaptations occurring relative to straight-line gait in typically developing children. Thus, the aims of this study were to analyse ground reaction forces (GRFs), ground reaction free vertical torque (TZ), and the lower-limb joint kinetics of 9...
متن کاملThe influence of soft tissue movement on ground reaction forces , joint torques and joint reaction forces in drop
The aim of this study was to determine the effects that soft tissue motion has on ground reaction forces, joint torques and joint reaction forces in drop landings. To this end a four body-segment wobbling mass model was developed to reproduce the vertical ground reaction force curve for the first 100 ms of landing. Particular attention was paid to the passive impact phase, while selecting most ...
