Investigation of the relationship of cobb angle with trunk muscle activity, trunk muscle endurance, cosmetic deformity and quality of life in adolescent idiopatic scoliosis individuals

The aim of this study is to examine the relationship between Cobb angle and trunk muscle activity, trunk muscle endurance, cosmetic deformity and quality of life in individuals with adolescent idiopathic scoliosis. It was conducted with people whose average age was 14.31±2.41 years, between the ages of 10-18, who were diagnosed with adolescent idiopathic scoliosis, whose Cobb angle was measured, scoliosis classification was made and Risser's sign was determined. Pressure Biofeedback Unit (Chattanooga Stabilizer Pressure Biofeedback) was used to evaluate deep trunk muscle activity. To evaluate trunk muscle endurance, Trunk Flexors Endurance test, Lateral Bridge Test, Modified Biering-Sorensen Test, Sit-ups Test and Modified Push-ups Test were applied. The Walter Reed Visual Assessment Scale was used to evaluate cosmetic deformity. The individuals' quality of life was measured with the SRS-22 (Scoliosis Research Society-22) survey. As a statistical method; The suitability of continuous variables for normal distribution was evaluated with the Kolmogorov Smirnov test. In independent group comparisons; In cases where parametric test conditions were not met for continuous variables specified by measurement, the Mann-Whitney U test or Kruskal-Wallis test was used. The relationship between two continuous variables was evaluated with Pearson or Spearman Rank correlation coefficients. p<0.05 was considered statistically significant. According to the results of the study, there was no statistically significant relationship between Cobb angle and trunk muscle activity and trunk muscle endurance in individuals with adolescent idiopathic scoliosis (p>0.05). A significant relationship was found between Cobb angle and Walter Reed Visual Assessment Scale shoulder level figure and quality of life (p<0.05). It was observed that as the Cobb angle increased, the perceived deformity severity increased and the quality of life decreased.
