This study aims to compare respiratory parameters -including pulmonary function and respiratory muscle strength-as well as aerobic capacity and sleep quality in individuals with thoracic adolescent idiopathic scoliosis. Participants will be categorized according to the ISST classification into T-type and TL-type curvature patterns. The study will evaluate differences between these groups using standardized clinical assessments.
This study aims to compare respiratory parameters (including pulmonary function tests and respiratory muscle strength), aerobic capacity, and sleep quality in individuals aged 12 to 20 years with thoracic adolescent idiopathic scoliosis (AIS), classified as T-type or TL-type based on the ISST classification. The study will be conducted at the Spine Health Center of Acıbadem Maslak Hospital.
A total of 30 volunteer participants will be included. Sagittal plane curvatures will be assessed using EOS imaging, and Cobb angles and axial trunk rotation (ATR) will be recorded. ATR will be measured using a scoliometer during the Adams forward bend test. Demographic data including age, sex, height, weight, and dominant side will also be collected.
Pulmonary function will be assessed using FVC and FEV₁ measurements, while respiratory muscle strength will be evaluated using the Cosmed Pony Fx device to measure maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP). Each test will be repeated three times, and the highest value will be used for analysis. Aerobic capacity will be evaluated using a progressive shuttle walk test. Sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI), and body image perception will be evaluated using the Scoliosis Appearance Questionnaire.
This is a cross-sectional observational study. Data will be compared between the T-type and TL-type scoliosis groups. The study will be supported by Üsküdar University, and all required devices will be provided by the university.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| T-Type | Participants diagnosed with thoracic type Adolescent Idiopathic Scoliosis (AIS), defined as a primary thoracic curve according to ISST classification. Eligible individuals are between 12 and 20 years of age and meet the inclusion criteria. All outcome measures, including pulmonary function tests, respiratory muscle strength, aerobic capacity, sleep quality, and body image assessments, will be evaluated in this group. | ||
| TL-Type | Participants diagnosed with thoracolumbar type Adolescent Idiopathic Scoliosis (AIS), defined as a primary thoracolumbar curve according to ISST classification. Eligible individuals are between 12 and 20 years of age and meet the inclusion criteria. All outcome measures, including pulmonary function tests, respiratory muscle strength, aerobic capacity, sleep quality, and body image assessments, will be evaluated in this group. |

| Measure | Description | Time Frame |
|---|---|---|
| Respiratory Muscle Strength (MIP, MEP) | Respiratory muscle strength will be assessed using an electronic mouth pressure meter (Cosmed Pony FX, ) by measuring Maximal Inspiratory Pressure (MIP) and Maximal Expiratory Pressure (MEP). This outcome evaluates the strength of inspiratory and expiratory muscles in participants with thoracic and thoracolumbar AIS. | At baseline (single measurement during study enrollment) |
| Measure | Description | Time Frame |
|---|---|---|
| Pulmonary Function (FVC, FEV₁) | Pulmonary function will be assessed using an electronic spirometry device (Cosmed Pony FX, ) by measuring Forced Vital Capacity (FVC) and Forced Expiratory Volume in 1 second (FEV₁). This outcome evaluates respiratory capacity in participants with thoracic and thoracolumbar AIS. | At baseline (single measurement during study enrollment) |

| Aerobic Capacity (Incremental Shuttle Walk Test, ISWT) | Aerobic capacity will be measured using the Incremental Shuttle Walk Test (ISWT) to determine exercise tolerance and endurance in participants with thoracic and thoracolumbar AIS. | At baseline (single measurement during study enrollment) |
| Sleep Quality (PUKI - Pittsburgh Sleep Quality Index) | Sleep quality will be evaluated with the validated Turkish version of the Pittsburgh Sleep Quality Index (PUKI). Higher scores indicate poorer sleep quality. | At baseline (single measurement during study enrollment) |
| Body Image (Scoliosis Appearance Questionnaire, SAQ) | Body image perception will be assessed with the Scoliosis Appearance Questionnaire (SAQ) to evaluate patients' perception of spinal deformity. | At baseline (self-administered questionnaire during study enrollment) |
