Acupuncture Pain Management


Part I: Theory
Overview of scientific bases of acupuncture
Mechanisms of pain management
Current researches and clinical trials
Pain Scores and evaluation methods

Scientific Bases of
Acupuncture

Neurohumoral
Morphogenetic
Nerve Reflex Theory
The gate control theory
of pain
Endorphin

Neuro-humoral Approach
Peripheral nervous
system to be crucial in
mediating the
acupuncture analgesia
Meridian-CortexViscera correlation
hypothesis

Neurohumoral Approach
Acupoint-brain-organ
Acupuncture stimulates
to brain cortex and
nerve system, then
control the chemical or
hormone release to the
disordered organs.

Morphogenetic Theory
Shang C. China, 1989
Acupuncture points are
singular points in surface
bioelectric field
The role of electric field in
growth control and
morphogenesis
Organizing centers have
high electric conductance
Acupuncture points
originate from organizing
centers

Nerve Reflex Theory


-Ishikawa and Fujita et al, Japan, 1950s
Autonomic nervous system
extending thru the internal
organs
Viscera-mutinous reflex
Cutanous Viscera reflex
Acupuncture utilize these
reflexes for restoring the
homeostasis of the body
and acceralate the healing
process.

The Gate Control Theory


Drs Melzack and Wall, 1965
Model for acupuncture pain
relief
Specific nerve fibers that
transmit pain to the spinal
cord (substantia gelatinous)
Balance between
Stimulation & inhibitory
fibers
Short term block pain by
acupuncture ( did not
explain the prolong effect)

Endorphin Theory
Dr. Pomeranz, Canada, 1996
Natural Morphine
Acupuncture trigger the
release of endorphin into
the central nervous system
Only deal with pain
Corticoids and Substance P
also released along with
endorphin

Therapeutic Mechanisms of
Acupuncture

Acupuncture Mechanisms of
Action
Conduction of
electromagnetic signals
Activation of opioids
systems
Changes in brain
chemistry-release of
neurotransmitters and
neurohormones.

Acupuncture Pathways

Meridian-Cortex-Viscera
Correlation Hypothesis
1. The meridian system is and connected the
nervous system to the cerebral cortex.
2. It acts through neurohumoral mechanisms
3. Acu-point-Brain-organ model: stimulates
the brain cortex/nervous system, then
controlling the chemical or hormone release
to the disordered organs for treatment.

Morphogenetic Singularity
Theory
Acupuncture points are
singular points in surface
bioelectric field
Converging points of
surface current for change
in electric current flow.
Abrupt transition from one
state to another.
Eg: BaiHui (Du 20)

Physical characteristics of the


acupuncture points-WHO
Points are corresponds to the high electrical
conductance points on the body surface
High density of gap junctions at the epithelia
of the acupuncture points.
Gap junctions are hexagonal proteins that
facilitate intercellular communication and
increase electric conductivity.

Research on Auricular points


WHO found 43 points
have proven
therapeutic value
Therapeutic effect can
be achieved by
needling, temperature
variation, laser,
ultrasound, and
pressure.

Effects of Acupuncture on the


Brain
UCI-Use functional MRI to
investigate the mechanisms
of acupuncture analgesia
Stimulates Li 4 revealed
activation of visual cortex.
Needling Tin Hui revealed
auditory cortex activation

Effects of acupuncture on the


Brain-auditory cortex

Why acupuncture has


fewer side effects?
May indirect adjust the process
and restore normal function by
activating the network of
organizing centers in the
organism
The activation of the selforganizing activity is less likely
to cause the side effects resulted
from directly antagonizing a
pathological process which often
overlap with other normal and
beneficial physiological
processes.

The role of electric field in growth


control and morphogenesis
Enhanced cell growth toward
cathode and reduced cell growth
toward anode in electric fields of
physiological strength
Fast growing cells tend to have
relative negativity polarity.
The polarity is due to the
increased negative membrane
potential generated by
mitochondria at high rate of
energy metabolism

Efficacy, effective, safety and costs of


acupuncture for chronic pain
Evaluated 304,674 patients
over 10,000 physicians and
received 10+ acupuncture
for pain
Results: acupuncture was an
effective and safe treatment
The effects attributed to
specific or nonspecific
mechanisms and depend on
the diagnosis-results a large
research initiative.

Mechanisms of acupuncture for


Pain relief
Polymodal receptors
(PMRs) in the acupuncture
points are sensitized for the
immediate action.
Action mediated by
endogenous opioids
Potent stimulus for
activating the analgesic
systems

Therapeutic Mechanisms of Acupuncture


-Dr.D. Kendall, 1980
1. Inserting a needle provokes an acute defensive
inflammatory response
2. Afferent nociceptive (pain) neurons distribute to the dorsal
horn of the spinal cord
3. Trigger the gamma loop efferent in the ventral horn and
activate neurons that cross over the spinal cord to the brain
4. Activate somatic motor nerves
5. To muscles, and autonomic motor nerves to peripheral
blood vessels and to the internal organs

Acupuncture Pain Management


Part II: Clinical applications
Differential diagnosis and treatment for
Headache & migraines, Trigeminal neuralgia,
Carpal Tunnel Syndromes, Arthritis, Neck
pain, Fibromyalgia, lumbago and sciatic
neuralgia.

Etiology of Headache
Blood Vessels that become
dilated enlarged or constricted
Muscles in the neck and head
become tight or tense
Muscles around the eyes the
become strained due to overwork
Sinuses became swollen due to
allergies or infections
Nerves that transmit abnormal
pain signals
Joints in the jaw and neck are
overused or damaged.

Types of Headache
-Western Medicine
I. Vascular headache (Migraines)
II. Muscle contraction headache
III. Combined vascular & muscle contraction
headache
IV. Headache of nasal vasomotor reactions

hypochondriacal states

especially on exposure to
wind.

nape of the neck and back
region.

by own antibodies in
the blood level which
causes inflammation.

the hand and wrist are
from nerve
compression, most
often compression of
the median nerve in the
carpal tunnel.

Anatomy of CTS

Diagnosis of CTS
Numbing pain in the
distribution of the median
nerve but not limited to it.
Phalens sign positive
Tinels sign positive
Light touch/vibratory touch
positive
Muscle weakness and
atrophy
EMG: slowed conduction
velocity across the CT.
