[Analysis of action potentials of muscles by a small general purpose computer (author's transl)].
To measure the duration of action potentials by a computer, the following steps are necessary: 1. automatic selection of suitable potentials from the EMG 2. identification of equal potentials (action potentials of the single motor unit) 3. measuring the durations of potentials, defined by the distance between first and last deviation from the base line. We noticed that the automatic evaluation of durations of single potentials is greatly deteriorated by base-line fluctuations. Therefore we average about 16 action potentials, stored in the computer, of the same single motor unit and measure the duration of the averaged potential.
