Continue Education Course of@Advanced Acupuncture, Inc.2007Acupuncture Pain ManagementPart 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 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.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 mechanisms3. 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 self-organizing 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 cord3. Trigger the gamma loop efferent in the ventral horn and activate neurons that cross over the spinal cord to the brain4. Activate somatic motor nerves5. To muscles, and autonomic motor nerves to peripheral blood vessels and to the internal organs

Acupuncture Pain Management

Part II: Clinical applicationsDifferential diagnosis and treatment for Headache & migraines, Trigeminal neuralgia, Carpal Tunnel Syndromes, Arthritis, Neckpain, Fibromyalgia, lumbago and sciaticneuralgia.

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 headacheIV. Headache of nasal vasomotor reactionsV. Headache of delusional conversion or hypochondriacal states

Migraine Headache

Classic Migraine Common migraine Cluster headache Hemiplegic and ophthalmoplegic migraine Lower half headache

HeadachePrinciple acupuncture points G 20 Taiyang Li 4 GV 20 Liv 3 G 8 T 3

TCM Classification of headache

1. Headache due to invasion of pathogenic wind into the channels and collateral: Headache occurs often, especially on exposure to wind. The pain may extend to the nape of the neck and back region. Tongue white coating, pulse floating

2. Headache due to upsurge of liver-yang: Headache distension of the head, irritability, hot temper, dizziness, blurred vision, Tongue red with thin and yellow coating Pulse thin wiry and rapid.

3. Headache due to deficiency of qi and blood: Lingering headache, dizziness, blurred vision, lassitude, pale complexion Tongue pale with thin white coating Pulse thin and thread

Trigeminal Neuralgia (TN)

Causation:-blood vessels compressing the Trigeminal nerve root as it enters the brain stem Peripheral pathology-neurovas compression Central pathology- hyperactivity of the trigeminal nerve nucleus

Classifications of TN

TN-Pathogenic Wind & Cold

Clinical manifestation:1. Acute onset 2. Usually affects V1 sensory3. Aversion of wind & cold or aggravated by4. Pain like cutting, boring and electric shock but transient ( few minutes)s5. Wind cold or wind heat symptoms

Causation of Carpal Tunnel Syndrome

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

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.

Etiology of CTS

Median nerve compression by tendonitis Usually due to repetitive motion of the wrist and hands.
