The aim of the study was to record the surface electromyography activities of important muscles of the horse's neck in various <jats:styled-content style=\"fixed-case\">HNP<\/jats:styled-content>s. The electrical activities of the m. splenius, brachiocephalicus and trapezius were recorded on both sides. Five horses, both with and without a rider, were examined in all three gaits on both hands in three different <jats:styled-content style=\"fixed-case\">HNP<\/jats:styled-content>s: a \u2018free\u2019 position, a \u2018gathered\u2019 (head higher, neck more flexed) position with the noseline in front of the vertical and a \u2018hyperflexed\u2019 position. Averages of ten consecutive gait cycles in each <jats:styled-content style=\"fixed-case\">HNP<\/jats:styled-content> were evaluated and compared by standard statistical methods. No difference between ridden and unridden horses could be detected. The m. brachiocephalicus was in the hyperflexed position in all gaits significantly (p\u00a0&lt;\u00a00.01) more active than in the gathered and free position, which were not significantly different. By contrast, the m. splenius was in the hyperflexed position less active than in the free position (p\u00a0&lt;\u00a00.02), in which it always showed the highest activity. In walking, the muscle activities in the free and gathered positions deviated significantly (p\u00a0&lt;\u00a00.01). The m. trapezius was in the hyperflexed posture during walking significantly less active than in the free (p\u00a0&lt;\u00a00.01) and gathered (p\u00a0&lt;\u00a00.01) positions with the strongest activities in the free position. Again, the free and gathered positions differed significantly (p\u00a0&lt;\u00a00.01). In trot, the same pattern occured, although the gathered and hyperflexed positions did not differ significantly. In the canter, the activities of the m. trapezius showed no differences between <jats:styled-content style=\"fixed-case\">HNP<\/jats:styled-content>s. In <jats:styled-content style=\"fixed-case\">HNP<\/jats:styled-content>s with the noseline in front of the vertical, the muscles of the topline (m. splenius, m. trapezius) are activated and trained. In the hyperflexed position, however, a major muscle of the lower topline (m. brachiocephalicus) is activated and trained.<\/jats:p>","DOI":"10.1111\/jpn.12210","type":"journal-article","created":{"date-parts":[[2014,6,23]],"date-time":"2014-06-23T12:49:22Z","timestamp":1403527762000},"page":"132-138","source":"Crossref","is-referenced-by-count":20,"title":["The effect of three different head\u2013neck positions on the average <scp>EMG<\/scp> activity of three important neck muscles in the horse"],"prefix":"10.1111","volume":"99","author":[{"given":"K.","family":"Kienapfel","sequence":"first","affiliation":[{"name":"Department of Animal Ecology, Evolution and Biodiversity Ruhr University Bochum Bochum Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,6,23]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439-0396.2012.01274.x"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.applanim.2008.10.001"},{"key":"e_1_2_6_4_1","volume-title":"Der Reiter formt das Pferd: T\u00e4tigkeit und Entwicklung der Muskeln des Reitpferdes","author":"B\u00fcrger U.","year":"1939"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2010.01701.x"},{"key":"e_1_2_6_6_1","unstructured":"Denderen J.
