Objective.臂丛神经牵拉性损伤可能发生在颈椎创伤性屈伸后，常见于机动车事故或福尔斯。放射学和传统的神经传导研究在许多情况下是阴性的。本研究试图简化、标准化和量化临床检查中最常见的阳性和阴性感觉异常。对38例臂丛神经牵拉性损伤患者及一组年龄和性别匹配的对照组进行了热检测阈值、疼痛阈值、振动阈值、压痛阈值和手臂抬高负荷试验阈值的定量分析。与对照组相比，患者组除热痛外，所有诱发痛阈均显著降低，但感觉检测阈沿着升高。定量的感觉所见可以大大促进和证实这种类型的损伤的诊断。这些数据与臂丛神经牵拉性损伤导致小感觉纤维系统功能障碍并导致神经病理性疼痛的假设一致。
Objective. Stretch injury to the brachial plexus may occur following traumatic flexion-extension of the cervical spine often seen in motor vehicle accidents or falls. Radiologic and conventional nerve conduction studies are negative in many cases. The present study was undertaken in an attempt to simplify, standardize, and quantify the positive and negative sensory abnormalities that are most often seen during the clinical examination.Methods. Quantitation of thresholds for thermal detection and pain, vibration, pressure pain and elevated arm stress test was performed in a series of 38 patients with the clinical picture of brachial plexus traction injury as well as a group of age and sex matched control subjects.Results. Significant decreases in all evoked pain thresholds, except for heat pain, along with increases in sensory detection thresholds were found in the patient group compared with controls.Discussion. Quantification of sensory findings may greatly facilitate and substantiate the diagnosis of this type of injury. The data are consistent with the hypothesis that brachial plexus traction injury causes dysfunction of small sensory fiber systems and results in a form of neuropathic pain.
