A method based on Information Theory for quantify the movement efficiency was proposed. The measurement of information provides a quantitative metric of motor efficiency. This measure is obtained from electromyographic (EMG) recordings and the kinematic of motor activity. Here, the EMG signals from middle right deltoid were recorded during dynamic contraction. These contractions were evoked by abduction-adduction arm movements at scapular plane. The arm movements were realized at different speeds and under different loading conditions. The efficiency of motor activity was then evaluated for each situation. The proposed method is suitable for situations in which motor activity is performed under non-stationary conditions (dynamic contractions).
