Following an injury to the head, the brain may be damaged in such a way as to impair its ability to control the body. Depending on the site and extent of the injury, the symptoms can vary greatly. The effects can include: problems with mobility, walking, balance, vision, speech, memory, and personality changes.

Each person affected will have his or her own individual rehabilitation needs.
Initially treatment would be in a hospital environment, as the injured person needs careful monitoring and supervision. Once his condition is stable, rehabilitation can begin and usually involves a team of many different professions working together.

Physiotherapy aims to retrain movement to regain function, co-ordination and balance and to prevent problems developing with muscle spasm and joint stiffness. A treatment programme may include specific exercises, stretches, positioning and movements.

Once discharged from hospital treatment can continue as an outpatient.
