BPI = Brief Pain Inventory; HADS-D = Hospital Anxiety and Depression Scale-depression subscale; HADS-A = Hospital Anxiety and Depression Scale-anxiety subscale; HFS = Hand Function Sort and SFS = Spinal Function Sort, normalized to 200 points; FCE = Functional Capacity Evaluation (kg). Correlation coefficient [46]: 0.20 to 0.39 = weak; 0.4 to 0.59 = moderate; 0.60 and greater = strong.
