FIG. 5.

Behavioral pain responses over time, recorded after punctate stimulus of tibial nerve stumps (mean ± SEM). Significant differences were seen between the groups at 2, 3, 6, 8, and 12 weeks (three-groups Kruskal-Wallis, *p-value <0.05). In addition, at 2 and 8 weeks, the SC group had a significantly higher pain response than the CNC group, at 3 weeks the SC group had a significantly higher pain response than the SNC group and at 12 weeks the SC group had a significantly higher pain response than both the CNC and SNC groups (Tukey and Kramer-Nemenyi, *p-value <0.05).
