This study aims to investigate the effects of brace use on shoulder position, upper extremity proprioception, and upper extremity function in adolescents with idiopathic scoliosis. Participants will be assessed under both in-brace and out-brace conditions. The control group's upper extremity proprioception and upper extremity function will be assessed under out-brace condition. Shoulder position will be evaluated using a photographic method, while upper extremity proprioception (angular deviation) will be measured with the Laser Pointer-Assisted Angle Reproduction Test. Upper extremity function will be assessed through muscle strength tests, the Closed Kinetic Chain Upper Extremity Stability Test, the Medicine Ball Throw Test, the Finger-to-Nose Test, the Nellson Hand Reaction Test, and the Minnesota Manual Dexterity Test. Adolescents diagnosed with idiopathic scoliosis who have been prescribed brace treatment and have no history of spinal surgery or neurological/musculoskeletal conditions affecting upper extremity function will be included. Individuals with congenital or neuromuscular scoliosis, previous spinal surgery, neurological disorders affecting proprioception, or those unable to comply with study assessments will be excluded. This study aims to provide insights into the impact of bracing on proprioception and upper extremity function, contributing to the development of rehabilitation strategies for scoliosis management.
To have a diagnosis of adolescent idiopathic scoliosis (AIS),
Be using Cheneau Type corset for at least one month,
Having a primary thoracic or thoracolumbar curve,
Cobb angle of 20 degrees or more,
Having a diagnosis of Congenital Scoliosis,
Becoming a Professional Athlete,
Neuromuscular, Rheumatologic, Renal Except Scoliosis, Any History of Vestibular, Pulmonary or Cardiovascular Disease Finding
History of Surgical Intervention on the Spine. Exclusion Criteria for Control Group;
This study will be carried out on adolescent idiopathic scoliosis individuals between the ages of 10-18 who have been using the brace prescribed by a physician for at least one month and age-matched healthy individuals. The corsets used by the individuals with scoliosis included in the study will be the previously prepared Cheneau type brace. Healthy individuals will be included in the study with the snowball method from the close environment of the individuals with scoliosis.

Not listed
Cobb Angle Measurement
Cobb angle, a standard measurement used to quantify spinal curvature in scoliosis, will be obtained from physician notes and radiographic images. A tangent will be drawn along the superior edge of the uppermost involved vertebra and the inferior edge of the lowest involved vertebra. Perpendicular lines will then be drawn, and the angle at their intersection will be recorded. Cobb angle will be measured both with and without bracing, and the difference will be noted. Unit of Measure: Degrees (°)
Angle of Trunk Rotation (ATR)
Trunk rotation will be assessed using a scoliometer during the Adams forward bending test. Participants will bend forward with arms hanging freely while the scoliometer will be placed perpendicularly on the spine and moved downward from the thoracic region. The highest degree of trunk rotation will be recorded. Unit of Measure: Degrees (°)
Upper Extremity Proprioception Accuracy
Proprioception will be assessed using the Laser Pointer-Assisted Angle Reproduction Test (LPAART) at 55°, 90°, and 125° in shoulder flexion and abduction. A laser pointer will be attached to the dominant wrist, and participants will position their arm to the designated angle with eyes open. After memorizing the position, they will attempt to replicate it with eyes closed. The deviation from the target angle will be recorded. Unit of Measure: Degrees (°) of deviation
Anterior Humeral Head Position
The anterior displacement of the humeral head relative to the acromion will be measured in two positions: (1) neutral shoulder position and (2) hands on hips (wrists extended, thumbs posterior). The distance between the anterior humeral head and the anterior acromion will be palpated, marked, photographed from 20 cm above, and measured in centimeters. Unit of Measure: Centimeters (cm)
Upper Extremity Muscle Strength
Isometric muscle strength of shoulder and elbow muscles will be assessed using a digital dynamometer (Power Track). Each test will be performed three times, and the highest value will be recorded in Newtons (N). Strength tests will include shoulder elevation (upper trapezius), flexion, abduction, internal and external rotation, elbow flexion, and extension. Unit of Measure: Newtons (N)
Hand Dexterity (Minnesota Dexterity Test)
Hand dexterity will be assessed using the Minnesota Hand Dexterity Test, which includes two timed tasks: (1) placing disks in holes and (2) rotating disks. The total completion time will be recorded. Unit of Measure: Seconds (s)
Hand Reaction Time (Nelson Hand Reaction Test)
Reaction time will be measured using the Nelson Hand Reaction Test, where participants will catch a dropped ruler between their thumb and index finger. The distance (cm) the ruler falls before being caught will be converted into reaction time using the formula: Reaction Time = √(2 × Distance / 980 ms²). The best and worst trials will be excluded, and the average of three trials will be recorded. Unit of Measure: Milliseconds (cm/ms)
Upper Extremity Coordination (Finger-to-Nose Test)
Coordination will be assessed using the finger-to-nose test. Participants will touch their nose and then the examiner's finger, repeating the movement for 20 seconds. The number of successful repetitions will be recorded. Unit of Measure: Repetitions in 20 seconds
