Comparison between normal and parkinsonian pattern of motor unit firing.
There are many approaches to the study of the activity of separate motor units (MU) in man. In humans alpha motoneuron activity consists in generating spike trains that innervate groups of muscle fibers thus building MU. In the present study we used a new evolution of the joint interval density analysis in patients with Parkinson disease.
