Muscle Weakness in Children
Children can develop muscle weakness for several reasons. Muscle weakness can be a sign of a serious health condition that needs medical care. Or it may be a temporary problem that goes away with minimal treatment. Often, a child has muscle weakness along with other symptoms.
The pediatric neurology team at Children’s Health expertly diagnoses the cause of muscle weakness in children. We offer specialized treatments for common and complex conditions that cause muscle weakness.
What is childhood Muscle Weakness?
A child with muscle weakness lacks the strength to move certain muscles the way they should. This lack of muscle strength makes it more difficult for a child to perform basic functions like walking, feeding or dressing themselves. A child may be able to perform these tasks, but it takes extra effort. As a result, a child with muscle weakness may tire more easily.
What are the signs and symptoms of Muscle Weakness in Children?
Muscle weakness symptoms in children include:
Difficulty crawling, standing, walking, running, jumping or climbing stairs
Inability to raise their arms, feed themself or pick up items and hold onto them
Trouble sucking, swallowing or speaking
Neurodevelopmental delays and developmental delays (not hitting milestones like rolling over or crawling as expected)
Lack (or loss) of muscle tone (soft, doughy muscles)
Floppy head and neck
Droopy eyelids or inability to track things with the eyes

These tests may include:
Developmental testing, to check for motor, language, social and behavioral delays
Electromyogram (EMG), to show how muscles respond to nerve signals
Genetic testing, to look for gene changes that cause certain disorders
MRIs or CT scans, to look for muscle changes that indicate neuromuscular disease
Muscle biopsies, to diagnose neuromuscular disorders and infections
Neurological examinations, to assess motor skills, balance and coordination
