A retrospective cohort study.
Some patients after median or ulnar nerve injury report a diminished sensibility in the fingers that are supplied by the uninjured nerve.
The purpose of this study was to evaluate the function of the uninjured nerve in patients after peripheral nerve injury to assess the presence and degree of its functional impairment.
There were 28 patients with median and 29 patients with ulnar nerve injury examined for sensory disturbances in the injured and uninjured nerves, using several tests assessing touch, temperature, and vibration sensibility.
In 16 patients after ulnar and 13 patients after median nerve injury, some disturbances in the uninjured nerve were found, mostly in individual tests. Only 8 patients had 3 or more different tests abnormal.
The injured nerve function in patients with functional disturbances in the uninjured nerve was worse than in patients with normal test results.
Posttraumatic changes in central nervous system are the possible reasons.
Level III study.
一项回顾性队列研究。
一些正中神经或尺神经损伤后的患者报告称，由未受伤神经支配的手指感觉减退。
本研究的目的是评估周围神经损伤患者中未受伤神经的功能，以评估其功能损害的存在情况和程度。
对28例正中神经损伤患者和29例尺神经损伤患者进行检查，通过多项评估触觉、温度觉和振动觉的测试，来检测受伤神经和未受伤神经的感觉障碍情况。
在16例尺神经损伤患者和13例正中神经损伤患者中，发现未受伤神经存在一些障碍，主要出现在个别测试中。只有8例患者有3项或更多不同测试结果异常。
未受伤神经存在功能障碍的患者，其受伤神经功能比测试结果正常的患者更差。
中枢神经系统的创伤后变化可能是原因。
三级研究。
