2 Comparison of East & West
Empirical Observations over Thousands Scientific Method & Case-Based Medicine Art of Medicine Technology of Medicine Holistic View Molecular and Organ View Circular Logic Linear Logic Energetic Mechanistic

3 What is Acupuncture? Acus meaning needle Pungare meaing to pierce
Zhenjiu meaning needle (zhen) and moxabustion (jiu) Manipulating body balance through regulating flow of Qi

4 Moxabustion Applied either moxa or heated element (1500° F) to arthritic joints Moxa burned in room Moxa was better & longer lasting

5 Scientific Evidence ?

6 What Scientific Evidence Exists?
Total Medline Cites for Acupuncture to Date Represents Publications (7085 non-human) 6430 Scientific Studies (376 non-human) 26,950 Total Sites About 1500/yr 25% Science About 300/yr 5% Science About 20/yr

7 Placebo Effect Study showed that, if something specific is measured, then there is no placebo effect. Only if the measure is subjective. So, “blindness” may not be valid in all cases.

8 NIH ‘97 Consensus on AP Effective for Osteoarthritis and Musculoskeletal Pain Effective for many GI Problems IBD, diarrhea, ulcerative colitis, peptic ulcers, dyspepsia, abdominal pain, nausea and vomiting Effective for Pulmonary disease asthma, colds

9 NIH ‘97 Consensus on AP Effective for Immunomodulation
reduces inflammation, elevates WBC,  interleukin-2 production Effective for Reproductive Disorders  uterine bleeding, ovulation

10 How Does AP Work? The physiologic effects of acupuncture therapy cannot be explained by a single mechanism, but rather a series of interactions among the Nervous System Endocrine System Immune System

11 AP Events Simple in concept, complex in action
Starts from Local Effects Expands to involve the entire Neural Axis

12 AP Events Local effects Segmental effects Central effects
Pain control Organ effects Central effects All take place at once

13 Basic Tenets of AP Based upon the AP point selected
Based upon the method of stimulation Dry needles Electrical AP Aquapuncture Hemoacupuncture Based upon the length of stimulation Low-rate, twisting stimulation of GV26 leads to endorphin response, while high-frequency needling of GV26 leads to epinephrine response

14 Effects of Acupuncture
Baseline Mannitol Using manganese-enhanced fMRI (functional magnetic resonance imaging), visual effects can be seen in human and animal neural tissues Mn Infusion EA GB34

15 Effects of Acupuncture
Activation of cortex is site specific Leads initially to specific effects GB34 ST36

16 Effects of Acupuncture
5 minutes 20 minutes Activation has temporal effects Longer stimulation activates more cortical structures Leads to broader effects

17 Effects of Acupuncture
In separate study, analgesic AP points were compared to non-analgesic points Analgesic AP altered brain regions involved in pain modulation PAG, MnR, hypothalamus, thalamus Non-Analgesic AP did not activate same areas

18 Method of Stimulation Stimulation of BL-20 (the SP association point) in horses led to analgesia using dry needles or electrical AP. Only EA increased release of endrophins into the blood.

19 Medication Timing & TCM 24-hour Clock

20 Anatomical Considerations
Acupuncture point Meridians Reflex Connections Central Connections

21 Shu Xue (communication outlet)
 Electrical resistance  Electrical conductivity High density of free nerve endings arterioles lymphatic vessels mast cells

22 AP Point Locations Points where neurovascular bundles where nerves penetrate the body fascia Points where nerves bifurcate

23 AP Points- -Bladder Meridian
Inner and Outer Bladder Meridian Points

24 Acupuncture points: 4 types
Type I: motor point; 67% of all the points maximal contraction with minimal intensity of stimulation the nerve enters the muscle LI-4 ( He-gu) Type II: dorsal & ventral midline superficial nerves in the sagittal plane #68 (Bai-hui)

25 Acupuncture points: 4 types
Type III: superficial nerves / nerve plexuses GB-34: common peroneal nerve (deep & superficial branches) PC-6: over the median nerve Type IV: Muscle tendon junctions Golgi tendon organ BL-57: gastrocnemius

26 HemoAcupuncture Points
Most AP points are associated with vascular elements (veins) Blood vessel walls (veins) appear to have AP points directly on or in them

27 Anatomical Considerations
Acupuncture point Meridians Reflex Connections Central Connections

28 Meridians: Myth or Reality?
Close correlation between AP Meridian Peripheral Nerve Pathways Meridians appear to possess bioelectric function similar to PN Meridians follow PN Lung (LU) = Musculocutaneous N Pericardium (PC) = Median N

29 Meridian Research Stimulation of AP points on meridian lower resistance at other meridian points Injection of radio-isotopes into one point gradually accumulates at other points Radio signals places over one AP point can be picked up at other AP points along the meridian Injection at acupoint Migration 6 cm/minute

30 14 Major Meridians Lung Meridian: LU Heart Meridian: HT
Pericardium M.: PC Spleen Meridian: SP Liver Meridian: LIV Kidney Meridian: KID Conception Vessels: CV Large Intestines M.: LI Small Intestines M.: SI Triple Heater M.: TH Stomach Meridian: ST Gallbladder M.: GB Bladder Meridian: BL Governing Vessels M.: GV

31 Meridians Energy flow system Chi (Qi): energy flow
AP points on 14 major meridians Normal: Energy flow all the time on all the meridians from one acupuncture point to another LU->LI->ST->SP->HT->SI->BL->KID->PC->TB->GB->LIV

32 Meridians Where there is no free flow, there is pain. Pain
Pathogenic factors Meridian No free flow Pain

33 Meridians Where there is free flow, there is no pain. Pain Normal
No free flow Pathogenic factors Meridian Acupuncture Stimulation Eliminating Meridian Normal

34 Anatomical Considerations
Acupuncture point Meridians Reflex Connections Central Connections

35 AP Effects Needle insertion stimulates afferent A-delta nociceptive fibers which leads to Local Effects Spinal Cord Effects Brainstem Effects

36 Acupuncture Pathway AP Stimulus is carried by afferent peripheral nerve Can be blocked by Procaine No AP analgesia on paralyzed limbs (somatosensory paralysis) Most profound AP analgesia is from points overlying major peripheral nerves

37 Acupuncture Pathway Stimulus enters the spinal cord
Integrated information ascends the spinal cord to the brainstem, thalamus and cerebral cortex

38 Gate Theory of Pain

39 Acupuncture & Pain Responses to heat electricity pinprick pinch AP
Naloxone  PT Analgesia

40 EA: Effect of Increasing Frequency
200 Hz 4 Hz 0.2 Hz Electrical Acupuncture

41 EA: Low Frequency ± Naloxone
Electro-acupuncture 4 Hz + saline 4 Hz + Naloxone

42 EA: High Frequency ± Naloxone
Electro-acupuncture 200 Hz + saline 200 Hz + naloxone

43 Mediators of AP Analgesia
Enkephalins & Dynorphins  Spinal Cord (Substantia Gelatinosa) Endorphins  Brainstem (Periaqueductal Gray Matter) 5HT  Brainstem (Raphe Nuclei)

44 AP Analgesia Varies among patients (species specific)
Varies from location of AP point Varies with proximity to AP point
