The comparison of Clinical Diagnostic Criteria for CRPS adopted by the IASP in 2012 and the characteristics observed in our CPIP model mice

Budapest clinical diagnostic criteria for CRPS adopted by the IASP in 2012 Characteristics observed in our CPIP mice
1. Continuing pain, which is disproportionate to any inciting event CPIP model mice showed persistent pain.
2. Must report at least one symptom in three of the four following categories: Not applicable (The symptoms can not be measured in CPIP mice)
  Sensory: Reports of hyperalgesia and/or allodynia Not applicable
  Vasomotor: Reports of temperature asymmetry and/or skin color changes and/or skin color asymmetry Not applicable
  Sudomotor/Edema: Reports of edema and/or sweating changes and/or sweating asymmetry Not applicable
  Motor/Trophic: Reports of decreased range of motion and/or motor dysfunction (weakness, tremor, dystonia) and/or trophic changes (hair, nail, skin) Not applicable
3. Must display at least one sign* at time of evaluation in two or more of the following categories: The signs of CPIP mice were consistent with most criteria
  Sensory: Evidence of hyperalgesia (to pinprick) and/or allodynia (to light touch and/or deep somatic pressure and/or joint movement) The CPIP mice showed hyperalgesia to von Frey filament stimulation and radiant heat stimulation, accompanied by spontaneous pain (Figure 1D-K)
  Vasomotor: Evidence of temperature asymmetry and/or skin color changes and/or asymmetry After ischemia/reperfusion, the temperature of ipsilateral hind paw of our CPIP mice was obvious increased in a short time (Figure 1C)
  Sudomotor/Edema: Evidence of edema and/or sweating changes and/or sweating asymmetry After ischemia/reperfusion, the thickness of ipsilateral hind paw of our CPIP mice was obviously increased in a short time (Figure 1A and B)
  Motor/Trophic: Evidence of decreased range of motion and/or motor dysfunction (weakness, tremor, dystonia) and/or trophic changes (hair, nail, skin) The distance traveled and velocity of CPIP mice in the open field test were decreased at the late stage of CPIP generation (Figure 1L and M)
4. There is no other diagnosis that better explains the signs and symptoms Not applicable

CPIP: Chronic postischemia pain; CRPS: complex regional pain syndrome; IASP: International Association for the Study of Pain.
