| Research Abstract |
Dysfunction in the lumbar multifidus muscles was attributed to the lumbar nerve disorders in intermittent low back pain. While the intensity of pain in the intermittent low back pain group was equivalent to that of motion provoked low back pain, poor oxidative response and joining of type I fibers instead of type II fibers during the multifidus muscle contraction were shown by hemodynamic and electrophysiological study. Surgical decompression of the affected nerves provided better outcome in intermittent low back pain than in motion provoked low back pain. Improvement of low back pain was not associated with back muscle function, which leads to the idea that treatment of nerve disorders plays a key role in intermittent low back pain rather than muscle strengthening therapy.
