Changes in the mechanical escape threshold after induction of MM inflammation and hyperalgesia. Two days after complete Freund’s adjuvant (CFA) or vehicle was injected into the skin overlying the ipsilateral MM, mechanical stimulation using von Frey filaments was applied to assess hyperalgesia in naïve and inflamed rats. Data are the mean ± SEM (naïve, n = 8; inflamed, n = 10). *P < 0.05.
