The pulse controlled laser acupuncture concept (PCLAC) has four components. The first component is a basic understanding of traditional Chinese veterinary medicine theories and the use of Channels and acupoints to diagnose and treat disease. The second component is a basic understanding of auriculotherapy and the use of auricular (ear) points to diagnose and treat disease. The third component is the diagnosis and selection of acupoints to treat based on changes in the arterial pulses when “active” (unbalanced) auricular and body acupoints are stimulated with a special device such as a 3-volt hammer or a low-level impulse laser therapy (LLLT) unit. Modern LLLT units have a wide range of frequencies and have both diagnostic and treatment capabilities. The changes in the arterial pulse when “active” acupoints are stimulated are due to vascular autonomic reflexes, called “reflex auriculo cardial” or vascular autonomic signs. Sensory nerves near the acupoint in turn stimulate sympathetic nerves to blood vessels that alter the pulses. The concept is called pulse-controlled (pulse-guided) acupuncture because the pulse changes determine the acupoints to be treated. The final component of the PCLAC is the use of LLLT to stimulate acupoints and treat local tissues. The PCLAC combines ancient TCVM wisdom, recent advances in diagnosis and treatment, conventional medical knowledge and modern technology to further expand TCVM diagnosis and treatment to improve animal health and recovery from disease.
