1st step is to look for high risk factors: PAD65

Paresthesias in Extremities, Age more than 65, Dangerous mechanism of injury (high speed, axial load, 1metre or 5 stairs, bicycle, recreational vehicle)

2nd Step is to look for Low risk factors: PARTS

Delayed onset of neck PAIN,
Ambulatory at any time
Simple Rear End Collision
No Midline Spinal Tenderness, or
Sitting in the ED

If any of these present, no Imaging, go to step 3

Lateral movement of neck 45 degrees
