Figure 3. A, Photograph of the cylinder test apparatus - transparent cylinder (20 cm in diameter and 40 cm high). Cylinder was positioned on a glass tabletop and exploratory movements were video-recorded from below through an angled mirror. B, The forelimb asymmetry task was used to measure the number of contralateral forelimb contacts compared to ipsilateral contacts while the animal reared in a cylinder. All damaged groups showed an increase in contralateral forelimb use after median and ulnar nerve crush at post (24 h) and day 7. At day 14, both treated groups improved, with no difference between treatments. At this time, only the animals from the crush group remained impaired. Data are reported as means ± SEM. ^*P < 0.05 compared to the control and sham groups (repeated measures ANOVA followed by the Duncan multiple range test).
