To learn the pelvic diaphragm release.
No but really. Yesterday, I had a patient with inanimate shear of one weeks duration. I had the tools to diagnose him and treat him affectively. He is now pain-free. Would he have gotten better on his own? Perhaps. Or this could have went on to be chronic LBP. Would one of my MD counterparts been able to accurately diagnose his cause of LBP? Unlikely.
OMT gives you an extra tool to put in your tool bag. And in medicine, it's nice to have tools. I personally have felt that the diagnostics have been more important than the treatment modality itself. I can't begin to tell you how valuable it is to diagnose leg length discrepancies, chest wall pain, neck pain, and lower back pain. I've seen patient who have seen every specialist in the hospital to treat their insidious onset of chest pain. Normal EKG, TTE, Stress test, PFT, CT chest. Who would think that a rib being pushed out of place could cause debilitating pain while someone ran? If you don't know it exists...you won't consider it apart of your differential.
