Abstract
OBJECTIVE: This study aimed to examine the suitability of using mean dorsal (hand) skin temperature (MDT) before and after a short typing task as an indicator of upper extremity musculoskeletal disorder (UEMSD) severity. In addition, MDT reproducibility in controls was assessed for a pre-typing and three post-typing time periods over three trials. METHODS: Asymptomatic office workers (n = 10) and office workers with distal UEMSD symptoms (n = 35) typed for 9 min at three ambient temperatures (18, 22, and 26 degrees C). Pre- and post-trial MDT was measured by infrared thermography. UEMSD severity was defined anamnestically by symptoms and by a physical examination and symptom-derived case definition. RESULTS: Good to excellent reproducibility (intra-class correlation coefficients = 0.46-0.85) for MDT was found in controls at 22 degrees C. At 18 and 22 degrees C, pre-typing MDT differed between controls and cases by number of symptom sites marked on a hand-arm diagram (ANOVA, P
