Analysis of individual parameters of paw print. (A) Print width is the width of the artificial box positioned around the paw print by the CatWalk software. Paw print could be recorded from 10 DPO. The width of the injured paw print was roughly 60–70% of normal value for several days, and rapidly recovered to normal values after 21 DPO. Print width of electro-acupuncture (EA) treated mice was significantly larger at 14 and 17 DPO. Total time for recovery was similar to control mice. (B) Print length is the length of the artificial box which the CatWalk software positions around the paw print. The print length of the injured paw was 65% of the normal value from 10–14 DPO and then rapidly recovered to a normal value at 26 DPO. The print length of electro-acupuncture treated mice showed the same length of time for a full recovery as control mice, but displayed a significant apparent and transient recovery at 14 DPO. ** p < 0.01, *** p < 0.001 (ANOVA).
