Natural Goal-Directecd Movements and the Triphasic EMG

WebDec 1, 1985 · Abstract In fast (time-optimal) movements about many joint systems, the triphasic EMG pattern has been observed. Although the first agonist burst obviously initiates the movement, the roles of the second and third bursts, appearing in the antagonist and agonist respectively, have been less clear. WebNormal, fast, and accurate elbow flexions had single-peaked velocities and a bi- or triphasic EMG pattern in agonist and antagonist muscles. During cerebellar dysfunction movements became ataxic. Ataxic movements were classified into two categories: those with oscillations (tremor) during the movement and those without oscillations. A terminal ... chasse manhattan bank.com https://stebii.com
