Background and objective
The cause of scoliosis remains unknown in 80-85% of adolescent patients. Treatment of adolescent idiopathic scoliosis (AIS) remains a complex challenge.
The goal of this study was to evaluate the predictive value of different factors [age, initial Risser俟Q製 score and initial Cobb俟Q製 angle, surface electromyography (SEMG), activity of both paraspinal muscles at the apex of the curve] in the progression of AIS.
Patients and methods
This study included 30 patients with AIS. Full history taking and spinal and neurological examinations were carried out. Initial Cobb俟Q製 angle and Risser俟Q製 staging were determined, together with SEMG of paraspinal muscles at the curve俟Q製 apex. Reassessment of Cobb俟Q製 angle and Risser俟Q製 score was done 1 year later.
Analysis of data was carried out with an IBM computer using statistical program for social science (version 18) software and services.
Quantitative data were presented as mean, SD, minimum and maximum values, and range. Qualitative data were presented as number and percentage, analyzed with the χ2 -test. Analytic statistics were calculated using Student俟Q製 t-test to compare two independent means. A receiver-operating character curve was constructed using Medcalc program 3.5.
Twenty-six girls and four boys with dorsal and dorsolumbar scoliosis were included in this study. There was significant increase in Cobb俟Q製 angle and Risser俟Q製 score. Age, Risser俟Q製 score, and SEMG results on the convex side were significantly correlated with progression of the curve. Cobb俟Q製 angle was the most sensitive predictor, followed by SEMG, whereas age, initial Risser俟Q製 score, and SEMG had the highest specificity as predictors.
Cobb俟Q製 angle, Risser俟Q製 score, and SEMG are specific, sensitive, and positive predictors for progression of AIS.
