Figure 6

Tactile acuity for median RMDQ in the abovemedian group versus the belowmedian group. (a) D-TPD, (b) A-TPD, (c) PTP, and (d) TPE. The median of RMDQ was 6. 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; RMDQ = Roland-Morris Disability Questionnaire.
