The purpose of this study was to assess the effect of upper and lower limb exertions on manifestations of upper limb global synkineses in hemiparetic subjects. <\/jats:p><jats:p> Design: Involuntary muscle activities on the affected upper limb of 11 hemiparetic subjects and on the left or right upper limb of 10 control subjects were recorded using surface electromyography during successive bilateral maximal ankle exertions and during contralateral grips. <\/jats:p><jats:p> Results: Significant differences in the level of involuntary electromyography (EMG) activities were observed between experimental conditions (ANOVAs, p &lt; 0.05). EMG levels in hemiparetic subjects were significantly higher during contralateral grip tasks than during the ankle exertions. <\/jats:p><jats:p> Conclusion: These results suggest that upper limb global synkineses are more prevalent in specific tasks and that this task specificity may reflect the neurophysiological mechanisms involved in the generation of global synkineses. <\/jats:p>","DOI":"10.1191\/0269215500cr340oa","type":"journal-article","created":{"date-parts":[[2005,8,8]],"date-time":"2005-08-08T23:22:42Z","timestamp":1123543362000},"page":"393-401","source":"Crossref","is-referenced-by-count":14,"title":["Effects of upper and lower limb static exertions on global synkineses in hemiparetic subjects"],"prefix":"10.1177","volume":"14","author":[{"given":"Patrick","family":"Boissy","sequence":"first","affiliation":[{"name":"Neuromuscular Research Center, University of Boston, Boston, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Bourbonnais","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Denis","family":"Gravel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A Bertrand","family":"Arsenault","sequence":"additional","affiliation":[{"name":"School of Rehabilitation, University of Montreal and Research Centre, Montreal Rehabilitation Institute, Montreal, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yves","family":"Lepage","sequence":"additional","affiliation":[{"name":"Department of Mathematics and Statistics, University of Montreal and Research Centre, Montreal Rehabilitation Institute, Montreal, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2000,8,1]]},"reference":[{"key":"atypb1","first-page":"404","volume-title":"Disturbances of nervous function.
