Clinician´s view: dynamic EMG

The research into a correlation between joint biomechanics and the action of muscles that act on the limb segment involved during movement has become very important in recent years. However, while the techniques for elaborating the EMG signal and its relationship with the dynamics of movement are described in detail in the literature, from a clinical point of view publications on how these techniques are used for clinical gait analysis applications are scarce. The purpose of dynamic EMG in clinical gait analysis is essentially to define the muscular activity that controls joint movement during gait, as shown by studies carried out on children with cerebral palsy, in which the abnormal pattern of muscle activation is used, for example, as an indication for surgical tendon transfer or lengthening
