This afferent volley can be altered by manipulating NMES parameters. Presently, we manipulated one such parameter, pulse duration, during NMES over the common peroneal nerve and assessed the influence on H-reflexes and CS excitability. We hypothesized that compared with shorter pulse durations, longer pulses would (i) shift the H-reflex recruitment curve to the left, relative to the M-wave curve; and (ii) increase CS excitability more. Using 3 pulse durations (50, 200, 1000 \u03bcs), M-wave and H-reflex recruitment curves were collected and, in separate experiments, CS excitability was assessed by comparing motor evoked potentials elicited before and after 30 min of NMES. Despite finding a leftward shift in the H-reflex recruitment curve when using the 1000 \u03bcs pulse duration, consistent with a larger afferent volley for a given efferent volley, the increases in CS excitability were not influenced by pulse duration. Hence, although manipulating pulse duration can alter the relative recruitment of afferents and efferents in the common peroneal nerve, under the present experimental conditions it is ineffective for maximizing CS excitability for rehabilitation. <\/jats:p>","DOI":"10.1139\/cjpp-2014-0195","type":"journal-article","created":{"date-parts":[[2014,8,19]],"date-time":"2014-08-19T21:34:36Z","timestamp":1408484076000},"page":"821-825","source":"Crossref","is-referenced-by-count":10,"title":["The pulse duration of electrical stimulation influences H-reflexes but not corticospinal excitability for tibialis anterior"],"prefix":"10.1139","volume":"92","author":[{"given":"Alyssa R.","family":"Hindle","sequence":"first","affiliation":[{"name":"Centre for Neuroscience, University of Alberta, 4-142 Katz Group Centre, Edmonton, AB T6G 2E1, Canada."},{"name":"Human Neurophysiology Laboratory, Faculty of Physical Education and Recreation, University of Alberta, E-488 Van Vliet Centre, Edmonton, AB T6G 2H9, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jenny W.H.","family":"Lou","sequence":"additional","affiliation":[{"name":"Faculty of Science, University of Alberta, 1-001 CCIS, Edmonton, AB T6G 2E9, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David F.","family":"Collins","sequence":"additional","affiliation":[{"name":"Centre for Neuroscience, University of Alberta, 4-142 Katz Group Centre, Edmonton, AB T6G 2E1, Canada."},{"name":"Human Neurophysiology Laboratory, Faculty of Physical Education and Recreation, University of Alberta, E-488 Van Vliet Centre, Edmonton, AB T6G 2H9, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"155","reference":[{"key":"refg1\/ref1","doi-asserted-by":"publisher","DOI":"10.1007\/s00421-011-2087-9"},{"issue":"1","key":"refg2\/ref2","doi-asserted-by":"crossref","first-page":"277","DOI":"10.1113\/jphysiol.1997.sp021857","volume":"498","author":"Bostock H.","year":"1997","journal-title":"J.
