Impedance control reduces instability that arises from motor noise.

5 Oct 2009 There is ample evidence that humans are able to control the endpoint impedance of their arms in response to active destabilizing force fields. However, such fields are uncommon in daily life. Here, we examine whether the CNS selectively controls the ... Read more...

Effect of electrode location on surface electromyography changes due to eccentric elbow flexor exercise.

29 Sep 2009 Experiments were carried out to determine whether the location of electrodes has an effect on eccentric exercise-induced changes in surface electromyography (sEMG) variables in the biceps brachii muscle. sEMG signals were recorded with a grid of 64 ... Read more...

Noninvasive estimation of muscle fiber conduction velocity distribution using an electromyographic processing technique.

30 Aug 2009 BACKGROUND: Electromyography (EMG) is useful in investigating muscle activation; however, noninvasive evaluation of surface EMG is limited due to its complicated waveform. This study investigated muscle structure and activation using an analysis ... Read more...
