“…However, these have only been used in the healthy (Campbell, Lloyd, Alderson, & Elliott, 2009;Monnet, Desailly, Begon, Vallee, & Lacouture, 2007) or non-stroke (Rettig et al, 2013) population. Electromagnetic tracking devices have been used in the stroke population to measure scapular position during humeral movement in the subacute phase (Beebe & Lang, 2009;Meskers, Koppe, Konijnenbelt, Veeger, & Janssen, 2005;Niessen et al, 2008;Price, Rodgers, Franklin, Curless, & Johnson, 2001) or chronic phase (Hardwick & Lang, 2011a;Massie, Malcolm, Greene, & Browning, 2012;Rundquist, Dumit, Hartley, & Kendall, 2012) but have not yet been used to measure changes within the glenohumeral joint centre during the acute post-stroke phase. Furthermore, changes in the position of the glenohumeral joint centre may be influenced by demographic and clinical characteristics such as age, gender, whether the left or right side has been affected by the stroke, hand dominance, motor recovery and muscle tone, but have not been explored in an acute stroke population.…”
