Leg Weakness in a Child

Many reasons exist for leg weakness in a child, but the only adequate way to discover the underlying cause is to make an appointment with a pediatrician and begin the process of diagnosis.

Significance

• Children complaining of weakness of the lower extremities may not always be a cause for alarm. When muscles are overtired, or a child is recovering from an illness or injury, some weakness may occur. However, if these causes have been ruled out, it is best to seek medical advice.

Types

• According to the Morgan Stanley Children's Hospital, there are approximately ten major types of neuromuscular diseases that may cause leg weakness, with multiple diseases in each main category. For instance, the Milton S. Hershey Medical Center lists nine different types of muscular dystrophies.

Diagnosis

• The Weill Cornell Medical College reports that there are several diagnostic procedures commonly used to rule out neuromuscular disease as the cause of leg weakness in a child. A physical exam, muscle biopsy or electromyogram is usually performed, as well as the appropriate blood tests.

Treatment

• One of the most important aspects of treatment for neuromuscular disorders in children is early intervention to prevent deformity and complications. The Nationwide Children's Rehabilitation Program recommends that a comprehensive physical therapy routine be established by a medical professional as soon as a definitive diagnosis is made.

Other Considerations

• Sometimes leg weakness in a child is idiopathic, meaning no known cause. This does not mean an underlying condition doesn't exist, it simply means the cause may be a disease which has not yet been discovered. In this situation, continuous monitoring by a pediatrician is advisable.
