Recovery of an injured CST is one of the motor recovery mechanisms in stroke patients （Hendricks et al., 2003; Jang et al., 2006, 2007; Swayne et al., 2008; Kwon et al., 2011, 2013; Kwon and Jang, 2012; Yeo and Jang, 2013; Rong et al., 2014）. Diffusion tensor tractography （DTT）, derived from diffusion tensor imaging （DTI）, and transcra- nial magnetic stimulation （TMS） have been widely used in demonstrating the recovery of an injured CST （Hendricks et al., 2003; Jang et al., 2006, 2007; Swayne et al., 2008; Pannek et al., 2009; Kwon et al., 2011, 2013; Kwon and Jang, 2012; Yeo and Jang, 2013; Rong et al., 2014）.
