WebSep 8, 2004 · Wrist flexion-extension movements Wrist movements were accompanied in all subjects by a triphasic pattern of EMG activity in the forearm muscles. This consisted of an initial burst of activity in the agonist muscle, followed by a burst in the antagonist muscle, and a second burst in the agonist. WebJun 13, 2009 · Early in the task surface EMG b shows discrete extensor and flexor bursts, with an alternating agonist–antagonist burst pattern. Smoothed rectified EMG traces c show this more clearly, and also demonstrate a triphasic agonist–antagonist–agonist activation pattern within each extension and flexion phase of movement ( arrows Ag1/2 = 1st/2nd ...

WebStartle reveals independent preparation and initiation of triphasic EMG burst components in targeted ballistic movements Muscles involved in rapid, targeted movements about a single joint often display a triphasic [agonist (AG1)-antagonist (ANT)-agonist (AG2)] electromyographic (EMG) pattern. WebFeb 1, 2008 · When these ballistic target movements are performed, similar patterns of triphasic electromyographic (EMG) activity are observed in the agonist and antagonist muscles. That is, two bursts in the agonist muscle (AG1 and AG2) are separated by a single burst in the antagonist muscle (ANT). インボイス とは ホテル
