Dr. Thomason demonstrates in this video how a small portion of the scapula can often be confused by clinicians to be the first rib, especially with patients that have poor shoulder girlde position related to bad posture. Remember, when mobilizing/manipulating the first rib… rule number one is… BE ON THE FIRST RIB! In order to do that effectively, we need to make sure our palpation is correct and not getting fooled by the scapula.
