Vasomotor disturbances in complex regional pain syndrome--a review.
TLDR
Measurements of skin temperature differences between the affected and the contralateral extremity can serve as a diagnostic tool in CRPS, in particular when sensitivity and specificity is increased by considering dynamic alterations in skin temperature asymmetries.
Multicenter study on the asymmetry of skin temperature in complex regional pain syndrome
TLDR
A considerable proportion of the patients that participated in this study did not meet the thermal criteria set forth by the IASP and AMA, and there was no correlation between symptom duration and skin temperature difference.
Does prolonged skin temperature measurement improve the diagnosis of complex regional pain syndrome?
TLDR
Commentary on a prospective study that explored the diagnostic utility of long-term temperature measurements in patients with upper extremity complex regional pain syndrome finds that improved identification of pain mechanisms will translate into better treatment outcomes, but this hypothesis remains to be tested.
Experimental approach to CRPS
Sympathetic dysfunction as a temporary phenomenon in acute posttraumatic CRPS I
TLDR
Sympathetic dysfunction is regularly seen at the onset of CRPS I and normalizes during the course of the disease, which suggests a posttraumatic sympathetic deficit playing a decisive role in the genesis ofCRPS I.
Identification of complex regional pain syndrome in the upper limb: Skin temperature asymmetry after cold pressor test
TLDR
This study adds further support for the accuracy of SkTA as a diagnostic indicator of CRPS to larger studies, which should also seek to replicate the findings for SkTA in the lower limbs.
Warm and cold complex regional pain syndromes
TLDR
The results indicate that warm and cold complex regional pain syndromes (CRPS) are associated with different clinical findings, beyond skin temperature changes, which might have implications for the understanding of CRPS pathophysiology.
Complex regional pain syndrome – diagnostic, mechanisms, CNS involvement and therapy
TLDR
Though there is no diagnostic gold standard, careful clinical evaluation and additional test procedures should lead to an adequate diagnosis, an early diagnosis and an interdisciplinary approach are important for optimal and successful treatment.

Vascular abnormalities in reflex sympathetic dystrophy (CRPS I): mechanisms and diagnostic value.
TLDR
It is suggested that, in CRPS I, unilateral inhibition of sympathetic vasoconstrictor neurones leads to a warmer affected limb in the acute stage, whereas sympathetic activity is still depressed.
Vascular abnormalities in acute reflex sympathetic dystrophy (CRPS I): complete inhibition of sympathetic nerve activity with recovery.
TLDR
Demonstrated for the first time is a complete functional loss of cutaneous sympathetic vasoconstrictor activity in an early stage of RSD/CRPS I with recovery, and results of investigations in healthy subjects ruled out the possibility that antidromic vasodilation caused by activation of nociceptive afferents is responsible for the complete depression of sympathetic vasoluntary reflexes.
Complex regional pain syndrome I (CRPS I): prospective study and laboratory evaluation.
TLDR
Clinical and autonomic laboratory probability scores correlate in an internally consistent manner and can be combined to provide an improved set of diagnostic criteria for CRPS I.
Value of autonomic testing in reflex sympathetic dystrophy.
TLDR
Sweating abnormalities correlate strongly with the clinical syndrome of RSD, and alterations in RST may be superior to clinical findings in predicting the response to sympathetic block, providing physiologic support for the unproven view of a natural disease progression ("stages"), with better treatment response and a warmer extremity initially.
Stress infrared telethermography is useful in the diagnosis of complex regional pain syndrome, Type I (formerly reflex sympathetic dystrophy)
TLDR
It is concluded that the stress IRT is a sensitive and specific indicator of CRPS-I.
Laboratory Findings in Reflex Sympathetic Dystrophy: A Preliminary Report
TLDR
Laboratory quantitation of autonomic indices enhances the clinical evaluation of patients with reflex sympathetic dystrophy and when sudomotor and vasomotor indices were combined, abnormalities were seen in all patients.
Validation of thermography in the diagnosis of reflex sympathetic dystrophy.
TLDR
Thermography can be a useful component of RSD diagnosis in situations where sensitivity and specificity are equally important, and an asymmetry cutoff of 0.6 degree C appears optimal.
