Quantitative Sensory Testing in Painful Hand Osteoarthritis Demonstrates Features of Peripheral Sensitisation

Table 2

Participant-reported outcome measures (PROMs). Data for duration of diagnosis, VAS in the hand OA versus the control group, Hospital Anxiety and Depression Scale (HADs) with subscales for anxiety and depression, and Health Assessment Questionnaire (HAQ) scores are shown with mean ± SD. 𝑃 values are shown for group comparisons between hand OA and healthy control participants. Differences between groups were analysed using the Mann-Whitney 𝑈-test with significance considered at 𝑃≤0.05.

Demographic	OA group	Normal group	𝑃 value
Duration of diagnosis (y)	6.1 ± 1.19	n/a	n/a
VAS score (mm) mean	59.3 ± 8.19	4.0 ± 1.89	<0.0001*
HADS depression score	3.2 ± 2.34	1.5 ± 1.66	0.05*
HADS anxiety score	7.5 ± 3.93	3.7 ± 3.20	0.01*
HAQ score	0.8 ± 0.10	0.11 ± 0.08	<0.0001*
