The QST values represent the mean of both shoulders. QST parameters are given as means ± SD. p-Values are based on raw data when the data are normally distributed and on log transformed data when they are non-normally distributed.

CDT, cold detection threshold; HDT, hot detection threshold; TSL, thermal sensory limen; CPT, cold pain threshold; HPT, hot pain threshold; TDT, tactile detection threshold; MPT, mechanical pain threshold; PSP, mechanical pain sensitivity for pinprick; DMA, dynamic mechanical allodynia; WUR, wind up ratio; VT, vibration threshold; PPT, pressure pain threshold.
