[A comparative study on the surface electromyography of lumbosacral multifidus muscle in patients with lumbar disc herniation]

To compare the degeneration of lumbosacral multifidus muscle in patients with lumbar disc herniation.Thirty-five healthy volunteers and 35 patients with unilateral LThe average myoelectric amplitude of the multifidus muscle of healthy volunteers was (48.84±7.77) µV on the left and (49.13±7.86) µV on the right. There was no significant difference between the two sides (Patients with chronic lumbar disc herniation have an imbalance in myoelectric activity, and the muscle strength of the multifidus muscle on the affected side is significantly reduced.
