Thrust and Fulcrum Position

by admin on May 31, 2012

Hi Everyone. I was speaking to a good friend about thoracic spine thrust and he thought I should post it. As we know, thrust is a helpful tool for getting “sticky” segments to mobilize. You can bias the outcome of flexion or extension dependent upon your line of thrust impulse and your fulcrum. In the first photo, an extended lesion (ie. loss of flexion) is depicted. The fulcrum (operator’s table hand) is supporting the superior segment (extended segment) of the dysfunctional unit. The thrust impulse (green bolt) is delivered just below the fulcrum causing a gapping or opening effect between segments allowing the superior segment more ability to now flex (black arrow). In the second photo, a flexed lesion (ie. loss of extension) is depicted. The fulcrum (operator’s table hand) is supporting the inferior segment of the dysfunctional unit (remember, the superior segment is the one limited in extension). The thrust impulse (green bolt) is delivered just above the fulcrum causing a closing effect allowing the superior segment more ability to now extend over the inferior segment (black arrow). Give it a try and let me know. See you next month.
