What are the limits of Osteopathy?
No one knows the limits of Osteopathy.”
John Martin Littlejohn
(except peer-reviewed literature)
Is Osteopathy only useful for treating musculoskeletal pain and injuries?
No - viscerosomatic reflexes, and somatovisceral input
Also, use of lymph techniques and other circulatory enhancing tachniques to improve venous return, possibly preload if necessary
Where does the sympathetic innervation of the heart have its origins? Where are the synapses?
Cord segments T1-5(6)
Synapses occur in the upper thoracic and/or cervical chain ganglia
Does SNS fiber distribution to the heart have something unusual about it? Is it perfectly symmetrical?
Sympathetic fibers to the heart do have a right- and left-sided distribution
Right sided fibers pass to the right deep cardiac plexus - innervate the right heart and sinoatrial (SA) node
Left sided fibers pass to left deep cardiac plexus – innervate left heart and atrioventricular (AV node)
What is the result of hypersympathetic activity (tone) to the right side of the heart (SA node)?
Supraventricular tachyarrhythmias
Sinus tachycardia
Paroxysmal supraventricular tachycardia (PSVT)
What is the result of hypersympathetic activity (tone) to the left side of the heart (AV node)?
Ectopic foci
Ventricular tachycardia
Ventricular fibrillation
What type of somatic dysfunction can increase sympathetic activity (tone) to the heart?
Upper thoracic dysfunction (especially extended segments)
Upper rib dysfunction, many times associated with upper thoracic dysfunction
Cervical dysfunction – affecting the superior, middle and inferior cervical ganglia
Where does the parasympathetic innervation of the heart have its origins?
Vagus nerves (cranial nerve 10)
Also have ipsilateral distribution:
Right vagus – innervates the sinoatrial (SA) node
Left vagus – innervates atrioventricular (AV) node
What is the result of hyperparasympathetic activity (tone) to the right side of the heart (SA node)?
Sinus Bradycardia
What is the result of hyperparasympathetic activity (tone) to the left side of the heart (AV node)?
AV Blocks
What is the course of the vagus nerve (cranial nerve 10)?
Originates on the medulla
Exits the skull via the jugular foramen between the occipital and temporal bones
Has connections with the first 2 cervical somatic nerves
Enters the chest via the thoracic inlet
What types of somatic dysfunction can affect the vagus nerves?
Occipitomastoid compression affecting the jugular foramen
Occiput, atlas and axis (upper cervical spine)
Thoracic inlet:
Upper thoracics
Upper ribs
Clavicles
Lower cervicals
Cervical fascia
ECT.
How is lymph drainage from the heart and lungs taken care of? Where does it drain, and what is the course of the lymph vessels? What drives this movement?
Lymphatic drainage from heart and lungs primarily carried back to the heart via the right lymphatic duct
Courses through the thoracic inlet on the way back into the heart
Driven by synchronized diaphragmatic function and muscle activity – overall body movement
Describe the relative dist of the body in terms of what each lymph vessel drains:
right lymphatic duct
left lymphatic duct
right lymphatic duct
- heart and lungs, right half of neck and head, right arm and shoulder
left lymphatic duct
- everything else
What 2 treatment modalities (other than drugs) that can improve lymph flow, and by how much?
OMM, in dog studies, can improve lymphatic flow by 4-5 times
Exercise can improve lymphatic flow by 30+ times
We can combine both for the benefit of the patient
What are some areas of somatic dysfunction that can negatively affect lymphatic flow?
Thoracic inlet
Respiratory diaphragm
Lower thoracics
Lower ribs
Upper lumbars (psoas major muscle)
Sympathetics
What are Chapman’s reflexes?
Chapman’s Reflexes
A viscerosomatic reflex mechanism
Associated with palpable nodules deep to skin and subcutaneous tissue
Can be used for diagnosis and treatment
Can be used to affect heart, renal and adrenal function
What can take a patient closer to threshold of sx and disease?
Allostatic load
- SD anywhere affects the individual locally and globally
Stressors/imbalance that takes them closer to the threshold of symptoms and disease-activates SNS-HPA couple
SD is frequently associated with what type of activity?
Hypersympathetic activity
Example – upper thoracic dysfunction may be associated with local hypersympathetic tone to innervated structures but also a global increase in sympathetic tone throughout the body
Overall, the entire individual is closer to their threshold for firing , more susceptible to imbalance and closer to the threshold for symptoms and disease
What is increased allostatic load associated with?
Increased allostatic load may contribute to breakdown of the cardiovascular, immune, renal, gastrointestinal and central nervous systems
How should osteopaths treat allostatic load - what is the philosophy?
Our job – to work knowingly with the system to allow health to manifest itself
As a result, multiple layers of dysfunction are removed to allow the underlying health to shine through
It is not a sequence of wresting holds to mindlessly apply to disease conditions
Osteopathy is art and science integrated into one
The overall result of a competently applied Osteopathic treatment is to improve the health, function and motion of the individual
Do our genes/DNA just randomly think for themselves?
Probably not! Epigenetics look at the genes as responding to multiple environmental signals that go into them
Positive signals may produce positive epigenetic expression and vice versa
Epigenetic abnormalities may be passed on for multiple generations unless the environmental signals are altered
What are some negative environmental signals that may have a negative impact on gene expression?
Poor nutrition
Toxic thoughts/mental stress
Physical stress
Environmental toxins
Somatic dysfunction
Others???
How common is HTN? What is it a risk factor for?
Affects a significant amount of the US population
Is a risk factor for:
coronary heart disease,
congestive heart failure,
ischemic and hemorrhagic stroke,
renal failure and
peripheral arterial disease
