[spinal stenosis with syrinx model (SSE)]
This video depicts the motion of a compliant spinal cord model with syrinx and stenosis.  Flow enters the model on the right (rostral) to the stenosis. 

[CSF system model layout (for SSE)]
General video showing CSF system model running with pulsatile CSF flow pump.

[Pressure variation in SSE model]
Depicts motion of compliant spinal cord model with syrinx and stenosis.  Flow enters on right.  Syrinx is pressurized by adding or removing fluid through a catheter leading into the syrinx cavity. 

[syrinx motion (larger size in vitro model)]
Larger size syrinx model with stenosis and laser Doppler vibrometer tape. 

[CSF pump sine wave]
CSF flow pump running with 1 Hz, 1 ml sine wave, connected to an early stage spinal cord model with syrinx. 

[CSF pump square wave]
CSF flow pump running with 1 Hz, 1 ml square wave, connected to an early stage spinal cord model with syrinx.
