Zone Technique

The Zone Technique is a chiropractic healing method which uses biomechanical and neurological input to restore health by improving the brain’s communication with the six zones of the body. Originally created by Dr. Therman Fleet in 1931, he taught the following:

The brain has six centers which connect to corresponding zones in the body:

  1. The Glandular System
  2. The Eliminative System
  3. The Nervous System
  4. The Digestive System
  5. The Muscular System
  6. The Circulatory System

The foundation of The Zone Technique is the theory that any disturbances in the body are within one or more of these zones and can be attributed to the brain’s inability to communicate effectively with that zone. Dr. Terrio will identify which zone or zones need healing in order to create a customized treatment plan for each patient.

Zone 1 The Glandular System

The glandular center in the brain controls all of the glands in the body which include the thyroid, adrenals, and reproductive organs, among others. Any trauma, disease or strain in the glands will cause a reaction along the nerves to the brain. If the strain is large enough, it can cause a block in regular nerve energy and result in overactive or under-active glands. Balancing the glandular system can improve energy levels, depression, focus, reproductive functions, and the immune system.

  • Glands of the head
  • Pineal, Pituitary, Memory, Energy, Skin, Hair
  • Glands of the stomach
  • Thyroid gland
  • Mammary Glands
  • Adrenals
  • Glands of the kidney region
  • Glands of digestion, Pancreas, Liver, Appetite, Sleep, Elimination
  • Glands of the pelvis, Uterus and Ovaries or Prostate and Gonads
  • Kidneys
  • Relaxation, Outlook on life, Temper, Concentration
  • Immune System, Hormonal System


Zone 2 The Eliminative System

The eliminative zone is composed of organs that remove waste from the body including the sinuses, urinary tract, skin, bowels, and lungs. If the eliminative zone is balanced, excretion is restored to normal levels. Conditions that can be treated by healing the eliminative systems include allergies, asthma, constipation, bladder issues, skin conditions and sinus problems.

  • Sinuses, Mucus elimination
  • Nasal passage
  • Throat, Nose, Bronchial tubes
  • Lungs
  • Kidneys
  • Bladder
  • Urination
  • Small intestine, Colon, Bowel movements
  • Skin
  • Toxins
  • Alkaline/Acid Balance

Zone 3 The Nervous System

The nervous system is controlled by the hemispheres of the cerebrum which is where our thoughts and emotions come from. The nervous system is made up of the nerve cells and fibers which connect throughout the entire body. If the zone is out of balance, there may be issues with many functions of the body including sight, hearing, the reproductive system, digestion, mood and sleep. Head trauma like concussions can also damage the nervous system. By balancing the zone, these functions may be restored so that you may have a healthy immune system and associated organs.

  • Nervous System
  • Eyes, Ears, Sense organs
  • Solar-plexus
  • Digestion
  • Mood, Relaxation, Sleep
  • Reproductive organs
  • Appetite, Elimination, Nerves
  • Immune System
  • Hormonal Balance


Zone 4 The Digestive System

The digestive system makes up the fourth zone and is closely linked to diet. In many cases, an unhealthy diet of preservatives and chemicals can wreak havoc on the digestive system. By balancing the zone through a proper diet, normal appetite can be restored, nutrients absorbed correctly, and food sensitivities decreased.

  • Liver, Appetite, Taste, Salivary Glands
  • Digestion
  • Gallbladder
  • Pancreas
  • Elimination
  • Bowels, Stomach glands
  • Intestines
  • Food Assimilation
  • Weight
  • Energy

Zone 5 The Muscular System

The muscular system controls all of the muscles which also directly influence spinal alignment and nerve connection. If there is an imbalance to the zone, balance and posture can be affected and increased muscle sensitivity or pain. Balancing this zone can restore balance, improve posture and eliminate chronic pain or acute pain.

  • Muscles in neck region and arms
  • Movement
  • Normal feeling
  • Nerve life
  • Muscles of the chest, abdomen and back
  • Spinal alignment
  • Normal tone, ease, strength
  • Muscles of the pelvic region and thighs
  • Walking
  • Muscles from thighs to feet
  • Relaxation, Immune System
  • Equilibrium/Balance/Center of gravity

Zone 6 The Circulatory System

Zone 6 is the circulatory system which moves blood through the heart, arteries, veins and capillaries of the body. If the zone is imbalanced, it can result in high or low blood pressure, varicose veins, heart problems or thyroid problems. Identifying and balancing the zone can reduce or eliminate these conditions.

  • Thyroid gland
  • Blood pressure
  • Heart, ease, strength
  • Blood vessels of back, arms, chest, abdomen, and lower extremities
  • Circulation
  • Lymph vessels
  • Movement of limbs
  • Relaxation
