Exploring muscle properties in children with spastic cerebral palsy

Botulinum Neurotoxin for Children With Cerebral Palsy: a Delicate Balance Between Clinical Benefits and Muscular Harm

Observational Universitaire Ziekenhuizen KU Leuven · NCT06991725

This study is trying to see how the muscles of children with spastic cerebral palsy are different from those of kids without the condition, using special imaging techniques to look at things like muscle size and fat content.

What this trial studies

This observational study aims to investigate the muscle composition and morphology in children diagnosed with spastic cerebral palsy (CP). Utilizing advanced imaging techniques such as quantitative Magnetic Resonance Imaging (qMRI) and shear wave elastography (SWE), the study will assess muscle fat infiltration, collagen content, and overall muscle size. By comparing these metrics in children with CP to typically developing peers, the research seeks to provide a comprehensive understanding of how muscle properties affect function in this population. The study will include children aged 2-16 years with varying degrees of CP severity, as classified by the Gross Motor Function Classification Scale (GMFCS).

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 2-16 years with a diagnosis of spastic cerebral palsy and specific motor function classifications.

Not a fit: Patients with dyskinesia, ataxia, or severe co-morbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of muscle function in children with spastic cerebral palsy.

How similar studies have performed: While there is limited quantitative data on muscle composition in CP, the use of advanced imaging techniques like qMRI and SWE is promising and may provide novel insights.
