摘要
Peripheral nerve injuries are common in clinical practice because of traumas such as crushing and sectioning. Lesions of the nerve structure result in lost or diminished sensitivity and/or motor activity in the innervated territory. The degree of lesion depends on the specific nerve involved, the magnitude and type of pres- sure exerted, and the duration of the compression. The results of such injuries commonly include axonal degeneration and retro- grade degeneration of the corresponding neurons in the spinal medulla, followed by very slow regeneration （Rochkind et al., 2001）. The adverse effects on the daily activities of patients with a peripheral nerve injury are a determining factor in establishing the goals of early recovery （Rodriguez et al., 2004）.
