Correlation Between 3 Phase Bone Scintigraphy and Pressure Pain Thresholds in Patients With Complex Regional Pain Syndrome (CRPS)

Germany53 participantsStarted 2010-10

Plain-language summary

The aim of the study is to investigate the correlation between increased bone metabolism in the 3 phase bone scintigraphy (TPBS) and decreased pressure pain thresholds in patients with complex regional pain syndrome (CRPS) of the upper limb and a non-CRPS-group. The investigators assume that there will be a significant correlation between the investigated values in the CRPS-group whereas the non-CRPS-group shows no significant correlation.
