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

WebAt the fastest movement speeds, triphasic EMG patterns (Ag 1 -Ant-Ag 2, Ag 1 being first activation of agonist muscle) were always present. This data indicated that the triphasic pattern of muscle activation was not switched on when a particular t mov was achieved. WebNatural goal-directed movements and the triphasic EMG.

WebJul 1, 2024 · During fast single-joint actions, both movements and force generation in isometric conditions, the typical triphasic EMG pattern shows an increase in the antagonist activation at the time of action initiation simultaneously with the first burst of activation of the agonist muscle, which produces torque in the desired direction ( Gottlieb et al. … chasse marine
