Adolescent idiopathic scoliosis: evaluating perioperative back pain through a simultaneous morphological and biomechanical approach

Table 4 Pain severity parameters – comparison between preoperative and postoperative time points

	Preoperative	6 weeks	P	6 months	P
APPT Worst Pain	4.85 ± 2.72	3.05 ± 2.33	0.027*	2.00 ± 2.00	< 0.001*
Neck Pain	0.30 ± 0.80	1.25 ± 1.92	0.043*	0.98 ± 1.53	0.044*
Thoracic Pain	3.50 ± 2.76	2.10 ± 2.32	0.042*	1.40 ± 1.96	< 0.001*
Lumbar Pain	3.30 ± 2.52	1.20 ± 1.61	0.005*	0.45 ± 0.95	< 0.001*
Pelvic Pain	1.63 ± 2.87	0.50 ± 1.00	0.265	0.33 ± 1.16	0.200
Painful Regions	1.90 ± 1.12	1.75 ± 1.07	0.625	1.10 ± 1.02	0.008*

All results are shown as mean ± standard deviation. All scores are based on a scale from 0 to 10, where 0 is no pain and 10 is the worst pain imaginable. Individual regional pain scores are based on the highest reported pain per area on a scale of 0–10. Painful regions are measured on a scale of 0 to 4, where 0 is no pain in any region and for every region where pain is felt there is the addition of 1 point. P values are given in regards to the preoperative and their associated postoperative time point values. Paired Student’s t-test, * = significance was reached when p < 0.05
