Ultrasonographic Evaluation of Abdominal Muscle Thickness Symmetry and Correlation With Pulmonary Function

Completed

• Conditions: Muscle Physiology; Adolescent Idiopathic Scoliosis
• Interventions: Diagnostic Test: Bilaterally abdominal muscle thickness with ultrasonography

• Registration Number: NCT04567914
• Lead Sponsor: Istanbul Physical Medicine Rehabilitation Training and Research Hospital

Brief Summary

We aimed in this study:

1. To compare the ultrasonographic measurements of the abdominal muscles thickness symmetry in patients with adolescent idiopathic scoliosis (AIS) and adolescent healthy individuals

2. To investigate the effect of measured thickness and symmetry on pulmonary function test.

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.

Arm && Interventions

Group	Intervention	Description
Adolescent idiopathic scoliosis	Bilaterally abdominal muscle thickness with ultrasonography	Ultrasonographic measurements were performed of bilaterally abdominal muscle thickness of AIS patients diagnosed by a specialist. Spirometry evaluation was performed by the investigator
Adolescent healthy individuals	Bilaterally abdominal muscle thickness with ultrasonography	Healthy adolescents aged 10-18 were selected. Ultrasonographic measurements were performed of bilaterally abdominal muscle thickness. Spirometry evaluation was performed by the investigator.
