Effect of m-PGA on MIA-induced locomotor deficit. The locomotor function at 3, 7, 14, and 21 days after MIA injection was assessed through walking track analysis and expressed as functionality index of the sciatic nerve (SFI). Values close to 0 indicate normal function while values tending to − 100 indicate total impairment. Results are expressed as means ± SEM (N = 10/group). §p < 0.05 and §§p < 0.0001 vs previous time point; *p < 0.05 and **p < 0.0001 vs vehicle; †p < 0.0001 vs non-micronized PGA
