Pain Sensitisation in Women with Active Rheumatoid Arthritis: A Comparative Cross-Sectional Study

Table 2

Cuff algometry parameters of patients and healthy control subjects.

Cuff algometry parameters	RA patients; mean (SEM)	Healthy controls; mean (SEM)	value
Pain detection threshold (kPa)	16.4 (1.2)	24.9 (2.0)	<0.01
Pain tolerance threshold (kPa)	40.5 (2.5)	55.9 (3.1)	<0.01
TS-index	0.98 (0.09)	0.71 (0.04)	<0.01

A regression analysis showed that there was no relationship between age and the measured pain parameters in the healthy control and the patient group.
The TS-index data was borderline to follow normal distribution with skewness/SE_skew being just at the limits and kurtosis/SE_kurt being well inside the limits of −1.96 and 1.96.
