We investigated the influence of pain sensitization on the prognosis of de Quervain’s tenovaginosis after a local corticosteroid injection. One hundred and fifteen patients with de Quervain’s tenovaginosis who were treated with corticosteroid injection were recruited. We initially measured pain sensitization by assessing the patients’ pressure pain thresholds in the mid-dorsal forearm and by administering a Pain Sensitivity Questionnaire. The pain score using a visual analogue scale, the result of Eichhoff’s test, and the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire were assessed at baseline and at 6 and 24 weeks after the injection. The DASH scores at 6 weeks correlated slightly with higher Pain Sensitization Questionnaire scores, and the DASH scores at 24 weeks correlated moderately with higher Pain Sensitization Questionnaire scores and lower pressure pain thresholds. Lower pressure pain thresholds, higher Pain Sensitization Questionnaire scores, and heavy manual work were independently associated with a higher likelihood of persistent symptoms and signs after a local corticosteroid injection for de Quervain’s tenovaginosis. Level of evidence: III.
