A review of 15 patients with posttraumatic syringomyelia indicates that the most reliable electrodiagnostic criteria for the diagnosis of syrinx are the loss of motor unit numbers with increase in motor unit amplitude and duration nd synchronous firing. Prolongation of F wave latency in a previously stable patient is a useful observation. Return of function and improvement of F wave latencies can occur rapidly following decompression of the syrinx. Forty per cent of the patients studied had concomitant involvement of at least one peripheral nerve as one would expect invoking the double crush hypothesis.
对15例创伤后脊髓空洞症患者的回顾表明，诊断脊髓空洞症最可靠的电诊断标准是运动单位数量减少，同时运动单位波幅和时限增加以及同步放电。对于先前病情稳定的患者，F波潜伏期延长是一项有用的观察指标。脊髓空洞症减压后，功能可迅速恢复，F波潜伏期也会改善。正如根据双重压迫假说所预期的那样，40%的研究患者至少合并有一条周围神经受累。
