-Flexion/extension/ hyperextension -Lateral flexion -Lateral rotation
Motion Segment
-Functional unit -Any 2 adjacent vertebrae and soft tissues between them
effects of impact forces
-High speed and collision → risk -Cervical flexion (large bending moment) + axial compression load = danger
spinal assessment physical examination testing
-If, at anytime, movement leads to increased acute pain or change in sensation or the individual resists moving the spine, a significant injury should be assumed and EMS should be activated
