About this study
Official title: Ultrasonographic Evaluation of Abdominal Muscle Thickness Symmetry and Correlation With Pulmonary Function Test in Adolescent Idiopathic Scoliosis
We aimed in this study:

- To investigate the effect of measured thickness and symmetry on pulmonary function test.
Read the detailed description
This cross-sectional,case-control clinical study included 40 patients diagnosed with AIS and 40 age and gender -matched healthy individuals. AIS group was evaluated for localization of curvature and degree of curvature. Ultrasonographic measurements and were performed of bilaterally abdominal muscle thickness in both groups. Spirometry evaluation was performed in both groups. Intragroup and intergroup data were compared.

Questions about this trial
What is this clinical trial studying?
An observational study of Muscle Physiology and Adolescent Idiopathic Scoliosis, run by Istanbul Physical Medicine Rehabilitation Training and Research Hospital at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 23 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Abdominal Muscle Thickness Symmetry (time frame: during evaluation, an average of 45 minutes). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04567914, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jan 2024; AzTrials last refreshed its copy on 8 Nov 2026.
