Predictability of motor outcome according to the time of diffusion tensor imaging in patients with cerebral infarct

Abstract: In terms of both positive and negative predictabilities, we found that predictability of DTT for motor outcome was better in patients who were scanned later (15-28 days after onset) than in patients who were scanned earlier (1-14 days after onset).

“…Our results were also agreed with Kwon et al [17] who found a direct relation between the degree of motor disability and the tractography findings with p value < 0.05. Also with Shereen et al [18] who found a significant statistical correlation between the findings of fibers tractography and the motor changes as well as the clinical outcome.…”

“…Our sample was smaller than eight of the studies we are aware of that have demonstrated an association between CST-FA and motor function Cho, Kim, Choi, et al, 2007;Jang et al, 2010;Kim et al, 2015;Kwon et al, 2012;Liu et al, 2012;Puig et al, 2013;Puig et al, 2011), and slightly larger than seven others (Grassel et al, 2010;Koyama et al, 2012;Kusano et al, 2009;Kuzu et al, 2012;Liang et al, 2007;Lindenberg et al, 2012;Ma, Liu, Li, Zhou, & Zhou, 2014). We also included participants with either ischemic or hemorrhagic stroke.…”

“…Our finding that lower CST‐FA was associated with poorer motor performance at 1 month poststroke has also been observed by other groups (Liang et al, ; Yu et al, ). A number of studies have reported a relationship between CST‐FA and motor performance at 6 months (Groisser, Copen, Singhal, Hirai, & Schaechter, ; Koyama et al, ; Kwon et al, ; Lindenberg et al, ). However, the present study and a number of others have failed to observe a significant relationship between CST‐FA and motor function at 6 months poststroke (Grassel et al, ; Puig et al, ; Yu et al, ).…”
