DR parameters of the lumbar (n = 15) and thoracic AIS (n = 10) patients.

Lumbar AIS (n = 15)	Cobb angle (°)	Maximum vertebral inclination angle (°)	Flexibility index of the convex side (%)	Flexibility index of the concave side (%)	Maximum thickness of the erector spinae muscles of the convex side (mm)	Maximum thickness of the erector spinae muscles of the concave side (mm)
Mean	26.8	15.5	−30	69.6	2.8	2.4
Standard deviation	9.7	6.8	24	19	0.27	0.23
P value*			0.001*		0.001*

Thoracic AIS (n = 10)	Cobb angle (°)	Maximum vertebral inclination angle (°)	Flexibility index of the convex side (%)	Flexibility index of the concave side (%)	Maximum thickness of the erector spinae muscles of the convex side (mm)	Maximum thickness of the erector spinae muscles of the concave side (mm)
Mean	32.5	11.9	−19.3	63.2	2.7	2.2
Standard deviation	13.7	5.2	48.2	23.7	0.85	0.83
P value^			0.001^		0.006^

P value*: P < 0.05, comparisons between the convex side and concave side in the lumbar AIS; P value^: P < 0.05, comparisons between the convex side and concave side in thoracic AIS.
