What Is EMG?
The letters EMG stand for Electro Myo Graphy, which refers to the measurement of electrical activity of muscles. In a similar way, ECG refers to Electro Cardio Graphy which is the measurement of electrical activity of the heart muscle. Just as cardiologists use ECG or EKG to accurately evaluate the heart, and neurologists use EEG to accurately evaluate the brain, Chiropractors, neurologists, researchers and clinicians use surface EMG to more accurately evaluate muscles. EMG measures the capacity of muscles to function.
How Does Surface EMG Work?
The small electric current, or signal, which comes from active muscles is detected by sensors placed on the skin directly above the muscles. The strength and pattern of the signal is seen on a computer screen and the data is collected in a software program that is able to run various analyses of the data to create useful reports regarding muscle function.
One of the most innovative technologies in contemporary Chiropractic Care, surface electromyography (sEMG) measures baseline status and changes in the electrical activity of the muscles that support your spine. These paraspinal muscles are controlled by the motor part of the nervous system. This scan enables 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 so that changes can be monitored over time. sEMG technology is similar to the technology used in EKG heart rate measurement machines. By precisely measuring muscle activity, your progress can be monitored as your care progresses, making the sEMG a powerful tool for tracking results from Chiropractic Care.
