Sensory Examination Scores: Mean scores (Mean) and standard deviation (SD) values of two-point discrimination (2PD) and tactile threshold discrimination (TTD) scores. 2PD scores are in centimetres. Tactile threshold discrimination (TTD) values are means of tactile threshold sensitivity values corresponding to filament thickness. Values of planned comparisons t values with associated significance values and Cohen's d effect sizes for comparisons between CLBP and Controls and Group 1 and Group 2 patients are reported. All data, except significance values have been corrected to 2 decimal places. *Statistically significant difference (p < 0.05).
