Maternal and fetal birthing simulators are disclosed.

The maternal birthing simulator may optionally be used with a pressure-based uterine propulsive system. The fetal simulator has an extensible spine, a movable head, movable clavicles, and arms articulated at the shoulder and elbow joints, and may include sensors to measure spinal extension, head rotation, applied traction force, and brachial plexus displacement.
