Dynamic Surface Electromyography (sEMG) measures
Similar to an electrocardiogram (ECG) which measures heart activity, dynamic SEMG measures paraspinal muscle activity (those on either side of the spine). Utilizing adhesive surface electrodes and by having the individual move through a range of motion, normal or abnormal muscle activity can be determined. Dynamic SEMG can determine the extent of muscle hypertonicity and dysfunction. This aids the practitioner in developing an accurate course of rehabilitation.
Like a video camera, the Dynamic sEMG watches the spinal muscles as they move.
If the Static sEMG Test discussed in the previous section was described as a "picture" of how the muscles respond to the vertebral subluxation, the Dynamic sEMG Test would be best described as a "video".

By knowing what patterns are characteristic of pain and dysfunction brought about by injury, this dynamic sEMG "tool" of the MyoVision System is particularly suited for documenting and managing patients that have been involved in automobile accidents.
