CRPS Stages

Progressive Clinical Stages of CRPS (1, 2, & 3)

Pain: more severe than expected; burning or aching; increased by dependent position, physical contact, or emotional disturbances Stage I
AKA Acute inflammation stage Stage I
Denervation & sympathetic hypoactivity occuring Stage I
Begins up to 10 days following injury & lasts 3-6 months Stage I
Hyperalgesia (lower pain threshold, increased sensitivity); Allodynia (everything painful); Hyperpathia (threshold to pain increased; once exceeded, sensation intensity increases more rapidly & greater than expected) Stage I
Edema- soft & localized Stage I
Vasomotor/thermal changes- affected limb warmer Stage I
Skin- hyperthermia, dry Stage I
Increased hair & nail growth Stage I
AKA Dystrophic stage Stage 2
Paradoxic sympathetic hyperactivity occurring Stage 2
Occurs 3-6 months afer onset of pain, lasts about 6 months Stage 2
Pain- worsens; constant, burning, aching Stage 2
Allodynia/hyperalgesia/hyperpathia almost always present Stage 2
Edema- becomes hard, causes joint stiffness Stage 2
Vasomotor/thermal changes- neither warm nor cold Stage 2
Skin- thin, glossy, cool (b/c of vasoconstriction), sweaty Stage 2
Thin, ridged nails Stage 2
Xrays reveals osteoporosis, cystic & subchondral bone erosion Stage 2
AKA atrophic stage Stage 3
Begins about 6-12 months after onset; may last for years or may resolve & recur Stage 3
Pain- spreads proximally, occasionally to entire skin surface or plateaus Stage 3
Edema- continues to harden Stage 3
Vasomotor/thermal changes- SNS regulation decreased on affected extremity, affected limb is cooler Stage 3
Skin- thin, shiny, cyanotic, dry; fingertips on involved extremity are atrophic; fascia thickened & contractures may occur Stage 3
X-rays reveal demineralization & ankylosis Stage 3
