If the injury to the nerves is mild, arm and hand function usually return after several months. If the nerves are actually torn, normal function may never be recovered. Fortunately, injuries of this severity are rare. If it appears that nerve function is not returning quickly, the arm and hand can be placed in splints while the infant is sleeping to maintain the normal joint function. Range-of-motion exercises may be recommended to keep muscles strong and active.
Splints can cause skin irritation or rash.
A child who has full recovery from brachial palsy will need no further treatment. A child who has mild to moderate nerve damage may need physical therapy to improve use of the arm and hand. A child who has full paralysis may need periodic physical therapy to adjust to using different equipment.
Brachial palsy can best be monitored by the caregiver and, as the child gets older, by the child. Any new or worsening symptoms should be reported to the doctor.
