Abstract: . Corticospinal excitability is lower during rhythmic arm movement than during tonic contraction. J Neurophysiol 95: 914 -921, 2006. First published October 26, 2005 doi:10.1152/jn.00684.2005. Humans perform rhythmic, locomotor movements with the arms and legs every day. Studies using reflexes to probe the functional role of the CNS suggest that spinal circuits are an important part of the neural control system for rhythmic arm cycling and walking. Here, by studying motorevoked potentials (MEPs) in response t… Show more

“…There is evidence that rhythmic movements in humans are also produced in part by spinal CPGs (Capaday et al 1999;Zehr and Stein, 1999;Carroll et al 2006;Zehr et al 2009). A great deal of this research comes from indirect measures of corticospinal tract excitability, which is one of the major descending pathways of the central nervous system (CNS) responsible for voluntary control of movement.…”

“…For the type of indirect research that is common in human work, this is most often conducted by contrasting a rhythmic motor output (such as walking or cycling) with a tonic, or isometric contraction. This type of methodology has been previously used in both leg ) and arm cycling (Carroll et al 2006;Forman et al 2014). The reason for this strategy's effectiveness is that the basic, alternating characteristics of rhythmic motor outputs, such as leg and arm cycling, are generated in part by spinal pathways (Zehr et al 2004), which are absent during tonic contractions.…”
