... saggital plane of torso (XZ) were examined for both reaches to a cup and to a spoon. Velocity profiles and curvature were also quantified for all trajectories. Results: We hypothesized that movements performed ... plane for all movements. Conclusion: The implemented minimum jerk trajectory model was not adequate for generating functional trajectories for these ADLs. The...
