I was watching some Youtube videos, and saw several touting ultrasonic techniques for cervical stenosis. I was surprised to not find any threads about this here (at least searching for 'ultrasonic' did not return anything).

Has anyone had experience with this technique? It appears to be claiming far less intrusive, less chance of damage to the spinal cord, quicker recovery etc.
It claims to be a newer technique, and I know from experience that many doctors only recommend what they were trained on, no matter how long ago.

Thanks,

Mitch
