Elevates 2nd rib
The ______ _______ muscle starts from the spine around the costal cartilage
external intercostal
The _____ _____ muscle starts from the rib angle to the sternum
Internal intercostal muscle
The ______ _______ muscle starts from the rib angle to the costal cartilage
innermost intercostals
The ______ handle motion is synonymous with the functional anterior-posterior rib axis
Bucket
The _______ handle motion is synonymous with the functional transverse rib axis
Pump
What are the various types of rib motion?
Bucket handle Pump handle Caliper Torsional Non-physiologic
Describe bucket handle motion. Which ribs does this involve?
move superiorly and laterally increases the transverse diameter ribs 1, 2 8-10
Describe pump handle motion. What ribs does it involve?
moves superiorly and anteriorly increases the a/p diameter ribs 3-7
The ribs move ______ and ______ with inhalation
Downward and posterior
The ribs move ______ and ______ with exhalation
upward and superior
_______ is the incomplete or partial dislocation of joint or organ
subluxation
Describe what happens to the right and left sixth ribs when T5 is rotated to the RIGHT (torsional movement)
RIGHT 6th rib: -posterior aspect turns externally -anterior extremity of the right sixth rib becomes more flat with inferior border sharp LEFT 6th rib: -posterior aspect turns internally -anterior extremity of the left sixth rib has superior margin accentuated
_______ ________ ______ is due to trauma or repetitive micro trauma
non-physiologic movement
What happens to the ribs during non-physiologic movement
rib becomes subluxed anteriorly or posteriorly one or more ribs become restricted in the deformed state
What are examples of the respiratory somatic dysfunctions?
Bucket handle Pump handle Caliper
What are examples of the structural somatic dysfunctions?
Torsional Non-physiologic
An inhalation dysfunction is a rib being held in a position of inhalation such that motion toward inhalation is more _____ and motion toward exhalation is _______.
free restricted
An exhalation dysfunction is a rib being held in a position of exhalation such that motion toward _______ is more free and motion toward _______ is restricted.
Exhalation and inhalation
The ____ ____ is the rib that maintains a group of ribs in dysfunctional motion
key rib
How do you treat a somatic dysfunction of a key rib?
BITE Bottom Inspired If a group of ribs is found to have Inhalation Dysfunction, the Bottom of the group is the key rib Top Expired If a group of ribs is found to have Exhalation Dysfunction, the Top of the group is the key rib
The key rib is at the ______ of the group during an inhalation dysfunction
bottom
Where is the key rib in an exhalation dysfunction?
At the top of the group
List the causes of rib dysfunction
thoracic scoliosis or hypnosis rib cage asymmetries bony diseases increased chest wall diameter abnormal muscle tension trauma lifestyle
What is pictured?
Pectus excavatum
What is pictured?
Pectus carinatum
What happens where there is deteroiration of vertebral support? (like kyphosis)
ribs become anteriorly depressed
COPD serves as an example of ______ ______ ______ _______ whcih can be a cause of a rib somatic dysfunction
increased chest wall diameter
