FIG. 3.

Mechanical and thermal sensory testing. (a) Mechanical allodynia testing demonstrated that training initiated at 2 weeks (W) post-spinal cord injury (SCI) leads to a significant decrease of allodynia scores in at-level dermatomes compared with non-trained controls (*p=0.027 W5, p=0.046 W6, p=0.029 W7, p=0.006 W8, p=0.003 W9, p=0.016 W10, p=0.002 W11, p=0.015 W12). In agreement with Basso-Beattie-Bresnahan scoring, it took approximately 3 weeks to see a significant training effect. (b) The Hargreaves test for thermal hyperalgesia of the hindpaws did not reveal significant differences between trained and non-trained groups. The mean of 10 trials (5 on right and 5 on left hindpaws) is shown. Importantly, training did not exacerabate thermal hyperalgesia.
