Muscle-ultrasound evaluation in healthy pediatric subjects: Age-related normative data

Area of Science:

• Pediatric Neurology
• Musculoskeletal Imaging
• Biomedical Engineering

Background:

• Muscle ultrasound examination (MUS) is a vital, noninvasive tool for diagnosing neuromyopathies.
• Existing standardized MUS normative data for pediatric populations are insufficient.

Purpose of the Study:

• To establish comprehensive, standardized muscle ultrasound normative data for healthy children.
• To provide essential reference ranges for pediatric neuromyopathy evaluation.

Main Methods:

• A muscle ultrasound study was conducted on 120 healthy children (ages 2-16).
• Bilateral muscle width and echogenicity were measured in 10 key muscle groups.
• Data were analyzed to determine age-related changes and establish confidence limits.

Main Results:

• Muscle thickness significantly increased with age across all measured muscles.
• Echogenicity showed age-dependent increases in specific muscles.
• Normative data and confidence limits for muscle width were established for pediatric age groups.

Conclusions:

• This study provides novel physiological muscle structural data for healthy children.
• The findings enhance the limited available references for pediatric muscle ultrasound.
• This research supports improved diagnostic accuracy for pediatric neuromyopathies using MUS.
