The study group for this research comprises patients diagnosed with idiopathic scoliosis, a condition characterized by abnormal lateral curvature of the spine of unknown cause.

In the physiotherapy evaluation, patients' spinal stability, rotary stability, and body awareness will be assessed.

Spinal stability will be assessed utilizing the Stabilizer Biofeedback Pressure device.Participants will lie on their backs on a Stabilizer Biofeedback Pressure unit connected to a manometer. The pressurized biofeedback device will be placed under the vertebrae and in the middle of the spina iliaca posterior superior (SIPS) by the physiotherapist. The valve of the manometer will be closed, and the cuff will be inflated to a pressure of 40 mm/Hg. Participants will then be instructed to perform the posterior pelvic tilt maneuver as demonstrated and maintain the position for 10 seconds. The value indicated on the manometer will be recorded. This measurement procedure will be repeated three times, and the average of these measurements will be utilized in the subsequent statistical analysis.

The Rotary Stability Test is a physical assessment used to evaluate an individual's ability to stabilize the spine and pelvis during rotational movements. During the test, the individual assumes a plank position (face down, supported by the toes and forearms) while maintaining a neutral spine alignment. Then, they are instructed to lift one arm and the opposite leg simultaneously while minimizing any rotation or movement in the torso and pelvis. The test measures the individual's ability to resist rotational forces.The patient will receive 3 points if the test is successfully repeated bilaterally, 2 points if it can be performed unilaterally, 1 point if there is a loss of balance during the test, and 0 points if the test cannot be completed.

Body awareness will be evaluated using the Body Awareness Questionnaire comprising 18 items. Participants will be instructed to rate each question on a scale of 1 to 7.The total score to be taken from the survey can be 126 or at least 18.Higher total scores indicate greater levels of body awareness, while lower scores suggest lower levels of body awareness.
