A computerized Surface EMG (surface electromyography ) is a highly sensitive Spinal Examination which can help determine the severity of a Vertebral Subluxation (spinal misalignment) by measuring increased electrical activity of the muscles associated with the subluxation. This is a functional test which can more precisely locate your trouble areas, measure muscular imbalances, and help determine your progress. This test can also help show if you have sustained a soft tissue injury as a result of an accident such as a car collision. Subluxations can cause a wide variety of symptoms including headaches, neck & back pain, muscle spasms, as well as interfering with, and causing abnormal function of your internal organs.
