[Purpose] The aim of the present study was to investigate effects of skilled reach
training with affected forelimb and treadmill exercise on the expression of neurotrophic
factor following ischemia-induced brain injury in rats. [Subjects and Methods] Thirty male
Sprague-Dawley rats were divided into 3 groups randomly: namely, the control sacrified 2
weeks after surgery, skilled reach training with forepaw contralateral to brain injury for
2 weeks, and treadmill exercise for 2 weeks. Transient focal cerebral ischemia was induced
by intraluminal occlusion of the left middle cerebral artery. After that, skilled reach
training and treadmill exercise were conducted. Western blot analysis was performed to
investigate expressions of neurotrophic factors. [Results] There were significant
differences in brain-derived neurotrophic factor and nerve growth factor expression
between the control group and the experimental group. There were no significant
differences in brain-derived neurotrophic factor and nerve growth factor expression
between the skilled reach training group and the treadmill exercise group. [Conclusion]
Skilled reach training and treadmill exercise can affect the expression of neurotrophic
factors.
