Nettetwere mapped for the soleus muscle by increasing stimulus intensity in 0.2- to 1.0-volt increments with 10-second rest intervals between stimuli, until the maximal M-wave and H-reflex were obtained. After determination of Hmax and Mmax, the intensity necessary to generate an H-reflex approximately 30% of Mmax (mean 31.5% ± 4.1%) was … Nettet4. nov. 2024 · 所以可见Hoffmann's reflex中文翻译为霍夫曼征,但有些人为反译时变成了Hoffmann's sign,又被另外一些人理所当然的误认为“霍夫曼征”了。不过,很多英文文献现在也无法区分这些了,Sign和Reflex常常混用。但不管怎样,都应该是德国神经学家Johann Hoffmann的贡献了。
