Short- and long-term changes in joint co-contraction associated with motor learning as revealed from surface EMG.

Abstract

In the field of motor control, two hypotheses have been controversial: whether the brain acquires internal models that generate accurate motor commands, or whether the brain avoids this by using the viscoelasticity of musculoskeletal system. Recent observations on relatively low stiffness during trained movements support the existence of internal models… (More)
