Correlations between Age, Pain Intensity, Disability, and Tactile Acuity in Patients with Chronic Low Back Pain

Figure 3

Tactile acuity for median general pain in the abovemedian group versus the belowmedian group. (a) D-TPD, (b) A-TPD, (c) PTP, and (d) TPE. The median of general pain intensity was 4. D-TPD = two-point discrimination test performed in a descending manner; A-TPD = two-point discrimination test performed in an ascending manner; PTP = point-to-point test; TPE = two-point estimation.
