400 Section - Gender differences of the clinical characteristics in young adult idiopathic scoliosis patients

71 young AdIS patients (22 male vs. 49 female) with an average age of (20.34±3.55) years and average main Cobb Angle of (29.96±12.21)°, were included. ATR, type of scoliosis, main Cobb angle , maximum thoracic kyphosis, lumbar lordosis, and sacral slope were measured. The bilateral grip strength, plank duration and six-minute walking distance of the patients were measured. The pain of the patients were measured by VAS score, the fall index of the patients was determined by using a balance tester, the anxiety of the patients was evaluated by SAS, and the quality of life was evaluated by the Chinese version of SRS-22 questionnaire. 


Results:

There was no significant difference in age, BMI, ATR, and main Cobb Angle between male and female AdIS patients. The ratio of scoliosis types in male and female patients was different. Among male patients, the thoracic curvature type was the most common, while among female patients, the thoracolumbar curvature type was the most common. There was no significant difference in maximum thoracic kyphosis, lumbar lordosis and sacral slope between male and female AdIS patients. The incidence of pain in young female AdIS patients was higher than that in male patients(57.14% vs. 31.82%). The grip strength on the dominant and non-dominant sides, plank duration, six-minute walking distance, and fall index of male AdIS patients were greater than those of female patients. 14.08% of AdIS patients had anxiety symptoms. There was no significant difference in the standard SAS score and the scores of the SRS-22 questionnaire between male and female AdIS patients.

Conclusion: Female AdIS patients have a higher incidence of pain, poorer grip strength, core strength and motor ability, while male AdIS patients have poorer balance function.
