title: Regeneration of the radial nerve in a dog influenced by electrical stimulation.
abstract: The effect of biphasic electric fields on nerve regeneration that follows injury to the left radial nerve of a dog was examined using electromyography (EMG). The left and right radial nerves were crushed with a serrated hemostat and the stimulating electrodes were positioned proximally and distally relative to the site of the injury. The left nerves received rectangular, biphasic current pulses (30 microA, 0.5 Hz) through the lesion for two months. The right radial nerves were treated as controls and regenerated without electrical stimulation. EMG activity was recorded intramuscularly from left and right musculus extensor digitorum (from Medical dictionary) communis (MEDC). Results obtained at the end of the two-month stimulation period showed a significant difference between the EMG activity of the stimulated and the unstimulated MEDC suggesting that the electrical treatment enhanced the nerve regeneration.
