Thermal Scan This scan measures temperature differential on one side of the spine compared to the other. When there is disturbance to the communication of the nerve system, the blood vessels are disturbed and it can cause the body's thermostat to malfunction producing an imbalanced temperature reading. The Central Nervous System controls the blood vessels and the organs and glands, known as the autonomic system. This thermal scan provides information regarding the autonomic system. Surface EMG Symmetry Scan Muscle Balance is extremely important because the vertebrae in the spine depend on the muscles to move properly. If one or more vertebrae are out of their normal position, it disturbs nerve function. This disturbance creates muscle imbalance caused by an abnormal amount of electrical current in the muscles on either side of the spine. As a result of this disturbance, the muscles can become weaker or stronger, tighter or fatigued. The abnormal muscle pattern on the scan reveals an increased amount of tension/pull on one side compared to the other (similar to a Tug-of-War). Surface Electromyography SEMG Scan This scan measures the amount of current in the muscles along your spine. Vertebral subluxations (misalignments) disturb the function of the motor nerves causing an abnormal amount of electrical current flowing to your muscles (indicated by colors and abnormal patterns). The Symmetry scan identifies muscle imbalance caused by an abnormal amount of electrical current in the muscles on either side of the spine. The abnormal muscle pattern on the scan revels an increased amount of tension on one side compared to the other side.
