Physical and Radiographic Findings Correlate with SRS Instrument in Nonsurgical Idiopathic Scoliosis

The purpose of this study was to assess the physical and mental status in nonsurgical idiopathic scoliosis by the SRS instrument. Forty-six patients under forty years of age were included to find the correlation between their physical and roentgenographic parameters and the SRS instrument. Parameters were ATI by inclinometer, Cobb angle of the main curve, plumbline, apical vertebra, and sagittal balance. Questionnaires of SRS-24 were translated into Japanese. Four domains were included: Pain, General self-image, Function, and General level of activity were calculated. No domain had significant correlation with age or sex. Pain had modest correlation with Cobb angle (r=0.43: p<0.01) and ATI (r=0.46: p<0.01). General selfimage had a weak correlation with ATI (r=0.38: p<0.01). Function had no correlation with any parameters. General level of activity has a weak correlation with Cobb angle (r=0.30: p<0.05) and apex (r=0.30: p<0.05). The SRS instrument could delineate the physical and mental status of scoliotic patients.
