Veterinary Acupuncture,an introduction

Presentation Outline

  • History of acupuncture

  • Traditional Chinese Medicine theories

  • Acupuncture points

  • Mechanisms of action

  • Where can you look for more info?

Eastern and Western Medicine

  • Western Medicine

    • New techniques

    • Historical understanding?

  • Eastern Medicine

    • Theories 1000s of years old

    • Historical understanding necessary

How long ago?

  • Some texts of acupuncture-- 200 BCE

  • Confucianism and Taoist views

  • Physiology and nature are tied


--A state of harmony existing between internal and external environments



  • Central core of the Yin/Yang theory

  • Neither can exist in isolation

















Natural World


  • Yin Organs--Liver






  • Yang Organs--Stomach

    Lg/Sm Intestine

    Gall Bladder

    Urinary Bladder

    Triple Heater

Classification of Energy

  • Remember Physics?

  • Potential Energy

  • Kinetic Energy

  • Qi

When the balance is lost…

Illness– an imbalance in the homeostatic mechanisms of the body

Disorders of Qi

Deficient Qi

Stagnant Qi

Rebellious Qi

Meridian Concept

  • Pathways

  • 1 meridian associated with each organ

  • Total= 14 used mainly in veterinary acupuncture today

The 5 Phases

The 8 Principles


  • History

  • Physical Exam–

    all senses

  • Five Phases

  • Eight Principles

How is it performed?

  • Thin, flexible, sterile needles

  • Pierce and stimulation specific acupuncture points (“acupoints”)

  • Stimulation causes a complex cascade of body responses


  • Over 1,000 have been located and mapped

  • Found mostly in depressions located along cleavages between muscles, tendons, and bones

  • Foci of increased electrical conductivity (lower skin resistance)

Lower Skin Resistance (LRS)

  • Caused by…

    • Local increase in capillary


    • A sympathetic reflex

    • ???

  • Observed at many, but not all, acupoints

    • In dogs, 79% correlation

  • Zones or narrow bands of LRS resembling meridians extending along the long axis of limbs

Structural Basis

  • High density of nerve fibers and vascular networks in the subcutaneous tissue at or near acupoints

  • Specific structures…

    • Free nerve endings

    • Muscle spindles

    • Golgi tendon organs

Free Nerve Endings

  • Free nerve endings tend to converge in bundles with vascular structures beneath acupoints

    • Perforate superficial


    • Enter skin

Form unique cylindrical structures surrounded by a sheath of loose connective tissue

Trigger Points (Travell and Rinzler, 1952)

  • Skin location that, when stimulated, produces pain in an adjacent or distant location

  • Suggested that this response

    was caused by blood vessels

    or nerves lying close to

    skin’s surface

Trigger Points, continued

  • Applied dry needling

    technique to trigger

    points to produce pain


  • 71% correlation

    between trigger points

    and acupoints

Examples of Locations

  • Superficial nerves or plexuses

  • Midline points where superficial nerves meet on the dorsal or ventral midline

  • Motor points (where nerves enter target muscle)

  • Muscle-tendon junctions (where Golgi tendon organs are abundant)

  • Sites where nerves exit bony foramina (supraorbital, infraorbital)

Mechanisms of Action

  • Neural Opiate Theory

  • Humoral Mechanism Theory

  • Local Mechanism Theory

  • Bioelectric Theory

Neural Opiate Theory

  • Acupuncture causes release of endogenous opioids into the CNS

    • Enkephalins

    • β Endorphins

    • Etc.

  • These opioids alter the integration and perception of pain

Humoral Mechanism Theory

  • Acupuncture causes release of a variety of humoral factors from the brain and other organs

    • Cortisol

    • Serotonin

    • Prolactin

    • Luteinizing


    • Etc.

Local Mechanism Theory

  • Needle stimulation is associated w/ a local defense reaction

    • Muscle contraction around needle

    • Coagulation cascade

    • Activation of complement


    • Vasodilation and increased

      vascular permeability

    • Mast cells degranulate

Bioelectric Theory

  • Meridians are conduits for sodium ions

  • Acupuncture induces the flow of sodium ions to deficient areas

    • Reducing cell lysis

    • Reducing pain

“It matters not whether medicine is old or new, so long as it brings about a cure.

It matters not whether theories are Eastern or Western, so long as they prove to be true”
