  1. Mean mode scores are presented for each LDD group with corresponding standard deviation (SD), standard error (SE) and confidence intervals. Post hoc tests indicated significant differences in mean mode 3 scores (M3) between ‘No LDD no pain’ and ‘LDD no pain’ groups and between ‘No LDD no pain’ and ‘LDD pain’ groups. Significant differences in mean mode 4 scores (M4) were also demonstrated between ‘No LDD no pain’ and ‘LDD pain’ groups
