Physiological rhythms are ubiquitous and essential to our life. They usually interact with one
another and also with the outside environment. Disappearance of normal rhythms and …

EMG and kinetic measures have been primary tools in the study of movement and have
provided the foundation for much of the work presented in this journal. Recently, novel ways …

The primary purpose of the present study is to determine if an organized control scheme
exists for the antagonist muscle during steady isometric torque. A secondary focus is to …

Abstract Background and Purpose. Global synkinesis (GS), or motor irradiation, is an
involuntary movement associated with the coactivation of numerous muscles in one limb …

Since muscle coactivation increases the stiffness and stability of a joint, greater coactivation
is likely during faster than slower movements. Very few studies, though, have been …

Background Ankle sprains are common joint injuries in daily and sports activities, whose
underlying mechanisms have been amply studied. If joint structures are directly damaged …

We present a system for polymyographic analysis which addresses detection of muscle
fatigue and strategies assumed by the central nervous system to deal with it. The system …

Co-activations of agonist and antagonist muscles are believed to be present in voluntary
limb movement. Recent studies indicate that such co-activations are either synergic or …

In reflex and volitional actions, co-activations of agonist and antagonist muscles are
believed to be present. Recent studies indicate that such co-activations can be either …

Rodent models of Parkinson's disease (PD) are usually assessed using measures of
akinesia, but other important parkinsonian symptoms such as rigidity are only rarely …
