用机械刺激激发腱反射,常用于腰骶神经根病的诊断。Stam和Tan的研究表明人工激发的与机械刺激器激发的腱反射同样可靠。本文应用一种手握式电子反射锤触发标准肌电图机扫描,测量了正常人所记录电位的起始潜伏时、峰—峰波幅和时限。 资料与方法 本文采用电子反射锤研究了24名正常自愿者(其中女17,男7;年龄23~58岁不等,平均36岁)的48个肢体上的踝反射(ATR)、膝反射(PTR)和肱二头肌反射(TTR)。采用表面
Mechanical stimulation of tendon reflex, commonly used in the diagnosis of lumbosacral radiculopathy. Stam and Tan’s research shows that artificial excitation is as reliable as mechanical stimulator-induced tendon reflexes. In this paper, we use a hand-held electronic reflex hammer to trigger a standard EMG scan and measure the peak-to-peak amplitude and time-delay of the initial latency of normal-recorded potentials. Materials and Methods In this study, ankle reflex (ATR) and knee reflex (ATR) were measured in 48 limbs of 24 normal volunteers (17 female, 7 male; ranging in age from 23 to 58 years old) PTR) and biceps reflex (TTR).
