Visceral Dysfunction OMT Flashcards
How is visceral pain developed?
Facilitation increases neural excitability at the level of viscera
- this triggers supernumerary impulses from afferent/efferent signals passing through the point of disturbance “cross-talk”
Common visceral pain areas:
- liver = back right kidney
- gallbladder = right scapula and back right shoulder
- stomach = upper middle back (T1-4 roughly)
- appendix = middle abdomen radiating to McBurney point
What are the 4 parts of the body that visceral diseases affect?
Autonomic nervous system
Blood circulation
Lymphatic circulation
MSK system
What is the difference between mobility and motility of the viscera?
Mobility:
- how organs move in response to forces generated outside the organ (peristalsis/cardiac movement)
- example: moves in the 3 planes (sagittal/coronal/transverse) with respect to respiration
Motility: (Barral)
- observation of organs moving in 3 planes with OWN rhythm (not induced by outside forces)
- is controversial and not much evidence backs this up
How does the diaphragm and viscera move with inhalation vs exhalation
Inhalation:
- diaphragm descents
- thoracic/ab contents descend and compress
- increases SVC blood flow but decreases portal vein blood flow
Exhalation:
- exact opposite above
How is the motility of organs affected with inspiration and expiration
Inspiration = moves away form midline
Expiration = moves towards the midline
rate is 7-8 cycles per minute and occurs even when breath is held
Visceral ligaments
Are considered viscoelastic
- when stress is present: deform and creation heat
- when stress is removed: return to normal shape, dissipation of heat and movement of fluid occurs
- increased mechanical tension causes fluid vessels to get compressed in the following order (needs more stress as you move down):*
1) lymphatics = edema
2) veins = congestion and edema
3) arteries = hypoxia
How to test for visceral dysfunctions?
Observation
Auscultation
Percussion
Palpation
- toxicity of cavity wall
- ease-bind of visceral articulations and fascia
- inherent rhythmic motion
- assessment of fascial strain
osteopathic screening exam
- go and treat the AGR area first
Motion testing with viscera
the greatest motion in the viscera is superior-inferior “cardinal movement”
Find ease of direction in superior-inferior
- once its found move the tissues to the “balance” point and then check tissues in left-right plane
- do this again but with counterclockwise-clockwise
Beginners visceral protocol
- narrow the differential down to a specific target organ*
1) treat the appropriate ganglia that corresponds to the organ in question
2) treat any viscerosomatic reflex by working on the vertebral dysfunction associated with the corresponding sympathetic spinal reflex level
3) treat the corresponding Chapman’s point for the viscera if present
4) treat the organ itself with MFR or other techniques
Celiac ganglia controls what organs?
Distal esophagus
Stomach
Proximal duodenum
Liver
Gallbladder
Spleen
Proximal pancreas
Superior mesenteric ganglia affects what organs?
Distal duodenum
Portions of the pancreas
Ileum
Jejunum
Ascending colon
Proximal 2/3 of the transverse colon
Inferior mesenteric ganglia controls what organs?
Distal 3rd of the transverse colon
Descending colon
Sigmoid colon
rectum
Indications for visceral OMT
Visceral dysfunctions with a known medical diagnosis or somatic dysfunction
Contraindications of visceral OMT
Abdominal aneurysm
Visceral ruptures
Internal bleeding
Infections uncontrolled by antibiotics
Severe pain induced by palpation or manipulation
Friability (acute inflammation)
- CD/UC, appendicitis, diverticulitis, hepatitis, pyelonephritis, infectious diarrhea
Non-healed incision or open wound
Pregnancy (uterus or round ligaments only)
Ventral hernias (Linea alba and ganglion releases)
Where do the ganglia of the GI viscera lie?
- all are behind (deep) the superior lines alba
1) celiac = below the xyphoid process
2) inferior mesenteric = just superior to the umbilicus
3) superior mesenteric = half way between the celiac and inferior mesenteric
** if any of the ganglia are dysfunctional, TTA is often appreciated**
