This paper develops a growth-adjusted anthropometric scaling framework to improve biomechanical analysis of infants by integrating CDC growth charts with motion capture data.

This study shows that joint angle trajectories in human reaching are robust to different segment length estimation methods, with minor effects compared to within-subject variability.

This study identifies stroke-related changes in muscle recruitment during reaching by analyzing tonic and phasic EMG components, revealing pathway-specific motor deficits.

The paper examines how biomechanical constraints affect control signal dimensionality during reaching movements, finding that gravity support requires more consistent muscle co-contraction than propulsion.

This study evaluates how joint impedance affects the accuracy and stability of dynamic leg simulations using explicit and implicit solvers, finding that viscoelasticity reduces errors in explicit methods.

This study investigates how the human motor cortex contributes to muscle recruitment for gravity compensation during posture and reaching, finding that motor evoked potentials correlate with postural muscle moments.

This study shows that the spatial organization of spinal motoneuron pools reflects the functional relationships between muscles they innervate, supporting neuromechanical tuning for upper limb movements.

This study shows that muscle torques are more sensitive than joint angles in detecting post-stroke motor deficits during reaching movements.

This study shows that primary afferent feedback cannot replicate the dynamic muscle activity patterns during reaching movements, suggesting that task-dependent muscle co-activation and nonlinear feedback are key to controlling limb dynamics.

The paper validates and scales musculoskeletal models of the human forearm and hand using posture-dependent moment arms, isometric force measurements, and error detection to improve accuracy in torque prediction.

This study examines how gravitational and dynamic muscle torque components relate to static and phasic muscle activity during reaching movements.
