Typically recovers over the course of the first 6 to 12 months of life.

Physiotherapy or occupational therapy is used in children with brachial plexus birth palsies in order to maintain motion and prevent contracture as the nerves reinnervate muscles affected by the initial injury.

Nerve reconstruction or muscle transfer surgery may be needed to improve function in children with incomplete recovery.
