Whiplash

Compression, Tension, Sheer all within 50-120 milliseconds.

“A 10 mile/hour collision is equivalent to catching a 200 lb bag of cement dropped from a second story window.”

Dr Scott Rosa

Whiplash Considerations

Ligaments

The ability, under physiologic loads, to limit patterns of displacement so as not to damage or irritate the spinal cord or nerve roots.

CSF circulation

Influences

• Cardiac

• Respiratory

• Vasomotor (autonomic)

Systole (brainstem and CSF move caudally)

Diastole (brainstem and CSF move cephalad)”

What happens when the venous outflow backs up? Brain shrinkage?

Respiration

“CSF motion may be connected to breathing as well as heart rate

Coughing & Valsalva

• Valsalva causes caudal and then cephalad movement of CSF

• Coughing causes a cephalad movement of CSF”

(Whedon & Glassey 2009)

Vasomotor

“Traube-Herring Mayer (THM) (Vasomotor) waves • …generated by spontaneous pulsations of arterial, venous and lymphatic vessels.• …independent of the respiratory and cardiac cycles• …generally longer wavelengths than those of the respiratory and cardiac”
