The nerve conduction part of the test usually takes longer than the needle exam because one needs to make calculations and measurements during it. On average, if one extremity is studied, the nerve conductions take anywhere between 15 and 30 minutes. The needle exam for one extremity usually ...
Among its various applications, the study of H-reflex and B-reflex stands out for its ability to unveil critical insights into nerve and muscle functionality. These reflexes, though less known to the general public, are indispensable in clinical neurophysiology. Let’s explore the sci...
EMG (electromyography), which records the electrical activity of our muscles, is a common test for muscle movement. This test helps determine whether there is a nerve injury or a muscle disease present, allowing the best course of treatment to be determined. EMG (electrical muscle activity) ...
while the other had undergone regenerative peripheral nerve interface (RPNI) amputation within the last 3 years. All three participants used negative pressure-type sockets and silicone liners. The participant who had undergone RPNI surgery participated in the electromyography (EMG) test in a dynamic...
Certainty of exclusive recruitment demands the isolation of nerve branches serving the target muscle7,8, which is not feasible. Here we circumvented this issue. We triggered and averaged surface EMGs separately with the firing instants of soleus and gastrocnemius motor units18. Instances of ...
Evoked laryngeal EMG has been described using a monopolar needle electrode percutaneously to stimulate the external branch of the superior laryngeal nerve and the RLN with recordings of the cricothyroid, thyroarytenoid, posterior cricoarytenoid, and cricothyroid muscles [24]. The optimal timing of...

In peripheral lesions, the frontal branches of the facial nerve are impaired, though in central lesions the forehead can still be focally innervated ipsilaterally and contralaterally (Beurskens and Heymans, 2004). Facial palsy is a relatively common condition that affects people across the age and...
the latter transmitting an electrical signal to a particular muscle and causing contraction thereof. The muscle itself is a volume conductor reacting to the signal of the associated nerve. There is a voltage change that occurs when a muscle contracts creating an electric potential that is directly ...
