Abstract

Smoothness of the upper limb endpoint trajectory depends on the joint angular velocities, accelerations, and jerks and on the instantaneous arm configuration and its rate of change during the movement. We compared the contribution of these components to the endpoint jerk when able bodied participants performed arm cranking on a cycle ergometer with 2 different crank lengths. There is significant effect of crank length on jerk partitioning.
