Quantitative sensory testing compared to conventional neurological diagnostics in patients with vibration induced vasospastic syndrome

Aim: To determine the somatosensory profile in patients with vibration induced vasospastic syndrome (VVS) using quantitative sensory testing (QST) compared to conventional neurography and testing of sudomotor function. Methods: We investigated 23 patients with VVS (55.3±11.2 y., 2 women, 21 men) over the clinically more affected hand. QST data was compared to age and gender matched healthy control subjects. We used the QST protocol of the German Research Network on Neuropathic Pain (DFNS) to determine 13 QST parameters, including thermal and mechanical detection and pain thresholds. Additionally we performed con…
