Table 2.
Cuff algometry parameters of patients and healthy control subjects.
| Cuff algometry parameters | RA patients n = 38 mean (SEM) |
Healthy controls n = 38 mean (SEM) |
p 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/SEskew being just at the limits and kurtosis/SEkurt being well inside the limits of −1.96 and 1.96.
