Assessment of Pelvic Floor Muscle Activation in Adolescents With Idiopathic Scoliosis

Adolescent idiopathic scoliosis is a three-dimensional deformity of the spine with a curvature of at least 10° on radiography, accompanied by rotation, seen in children aged 10-18 years, the cause of which is unknown. The pelvic floor consists of muscles and connective tissue in the shape of an equilateral triangle bounded by the symphysis pubis at the front, the sacrum at the back, and the ischial spines at the sides. The pelvic floor supports the pelvic organs, controls intra-abdominal pressure, maintains urinary and faecal control, and provides dynamic support to the body in conjunction with other core muscles. The aim of our study is to investigate pelvic floor muscle activation in adolescents with idiopathic scoliosis. Our study will include volunteers diagnosed with adolescent idiopathic scoliosis at Istanbul Gaziosmanpaşa Training and Research Hospital who have been referred to the Spine Unit of Gaziosmanpaşa Physical Therapy Training and Research Hospital for control purposes (presence of scoliosis in the family, postural abnormalities in appearance). X-rays will be taken, and volunteers with Cobb angles below 10 degrees will be included. Taking into account a 15% loss of the calculated sample, a total of 19 patients will be included in the study. The study group will consist of individuals diagnosed with adolescent idiopathic scoliosis, and the control group will consist of healthy individuals without spinal deformities. Each individual who agrees to participate in the study will undergo evaluations. For the study group, evaluations will include Cobb angle (radiography), trunk rotation angle (forward bending test), pelvic floor muscle activation (Neurotrac Myoplus 4 Pro) for both groups, and health-related quality of life (Paediatric Quality of Life Inventory).
