Consideration of lower extremity function
•Lower extremities, dependent as well on core stability, must be closely monitored as well.
•It has been noted throughout the literature that children with a brachial plexus birth injury often lack usage not only of the affected upper extremity but also of the same side lower extremity.  This may be due to the involvement of the spinal cord in a severe injury but can also be found in the child with a more mild injury.
