Introduction: There is currently no standardized method for measuring wrist kinematics in a 4D CT scanner. Various methods of wrist motion during a 4D CT scan have been reported in the literature, including asking the patient to move the wrist or using a motion guidance device. No research was done into …

Force transmission across the wrist during a grasping maneuver of the hand was simulated for three children with juvenile idiopathic arthritis (JIA) and for one healthy age-matched child. Joint reaction forces were estimated using a series of springs between articulating bones. This method (i.e., rigid …
