What Is Surface Electromyography?
Surface electromyography is one of the most exciting technologies in contemporary chiropractic practice. Surface electromyography (sEMG) measures baseline status and changes in the muscles’ electrical activity that supports your spine.
Why Measure Muscle Tone with sEMG?
Measuring the tone of muscles is a part of just about every chiropractic evaluation procedure. Muscle spasm is an objective finding of stress in the spinal column. Motor nerves control the paraspinal muscles along the spine. The abnormal tone of these muscles indicates issues with the nerves in that area of the spine.
Surface EMG is a safe and effective way to measure muscle tone and nerve activity from the spine. Extensive research shows that sEMG is both a reliable and accurate way of assessing spinal nerve activity.
What Does The Scan Show?
This scan allows your chiropractor to identify areas and patterns of abnormal stress in the motor nerves that may create tension, poor posture, and misalignment in the musculoskeletal system. Areas of muscular imbalance are measured and mapped. The mapping is essential to monitor changes over time.
Why Use Insight sEMG Technology?
The Insight sEMG technology is similar to the technology used in EKG heart rate measurement machines. One primary difference is that the Insight sensors are 1,000 times more sensitive since the paraspinal muscles generate less electrical activity than the heart muscle. The sensitivity and accuracy of the Insight technology is unsurpassed!
By precisely measuring muscle activity, your progress can be followed as your care progresses, making the sEMG a powerful tool for tracking results from chiropractic care.
