The Relationship Between Lumbar Disc Herniation and Urinary Incontinence

EMG activity shows the electrical activity measured during striated muscle contraction. The electrical activity of the muscle is in microvolts (1 volt = 1,000,000μV). Biofeedback units usually produce audio or visual feedback depending on the amount of electrical activity. Recording the bio-electrical activity of the muscle is a practical indicator of its contractility.
