Fig. 2. P + M induces gait abnormality in mice.

a Schematic illustration of gait analysis measurements of stride length and stride distance was shown. b–e After 2, 4 and 6 weeks of initial P + M treatment, the distance between subsequent limb placements (stride length) was measured. f, g The stride distance between limb placements of the mice was detected. *p < 0.05, **p < 0.01
