Neurographic studies are an extension of clinical examination and are performed for the functional assessment of peripheral nerves. The study of motor and sensory conduction velocity and the presence, amplitude, morphology and symmetry of the response to electrical stimulation are crucial for the diagnosis and management of peripheral neuromuscular disorders. Neurography also plays an important role in the search for so-called late responses comprising the F wave, H reflex, axonal response and A wave. By analysing the parameters of each late wave, this paper addresses the pathophysiological features and the most common conditions impairing the physiology of late responses, with a special focus on A waves.
神经电生理检查是临床检查的延伸，用于评估周围神经的功能。运动和感觉传导速度以及电刺激反应的存在、波幅、形态和对称性的研究对于周围神经肌肉疾病的诊断和治疗至关重要。神经电生理检查在寻找包括F波、H反射、轴索性反应和A波在内的所谓迟发电反应方面也发挥着重要作用。通过分析每个迟发电波的参数，本文探讨了迟发电反应的病理生理特征以及影响其生理功能的最常见情况，特别关注A波。
