• Vasomotor: reports of temperature asymmetry and/or skin color changes and/or skin color asymmetry

• Sudomotor/edema: reports of edema and/or sweating changes and/or sweating asymmetry

• Motor/trophic: reports of decreased range of motion and/or motor dysfunction (weakness, tremor, dystonia) and/or trophic changes (hair, nail, skin)

3. Must display at least one sign at the time of evaluation in two or more of the following categories:

• Sensory: evidence of hyperalgesia (to pinprick) and/or allodynia (to light touch and/or temperature sensation and/or deep somatic pressure and/or joint movement)

• Vasomotor: evidence of temperature asymmetry (> 1) and/or skin color changes and/or asymmetry

• Motor/trophic: evidence of decreased range of motion and/or motor dysfunction (weakness, tremor, dystonia) and/or trophic changes (hair, nail, skin)
