Fig. 7. Mg²⁺-releasing MPs relieve pain and gait in a rat OA model.

(A) Schematic diagram of measurement indexes for gait analysis. (B) A photograph of the rats’ gait after conditional treatment for 2 and 4 weeks. (C) Spatial symmetry calculation results of the rats after conditional treatment for 2 and 4 weeks (n = 6). (D) Pain threshold of the rats tested at 2 and 4 weeks after conditional treatment (n = 6). Notes: All data are shown as the means ± SD. Statistical differences between groups were determined by one-way ANOVA. **P < 0.01; ****P < 0.0001.
