Rehabilitation Medicine is the diagnosis, assessment and management of an individual with a disability due to illness or injury. Rehabilitation physicians work with people to help them achieve an optimal level of performance and improve their quality of life.

Rehabilitation medicine differs from other types of medical practice in several ways. A major focus is on preserving residual function and preventing secondary complications (physical, physiological, behavioural, or social) that lead to increased disability or pain. 

Rehabilitation is geared to the needs of people with multifaceted problems and, therefore, tends to take a multidisciplinary approach to treatment in which experts from a few pertinent disciplines work together to design and implement treatment plans.
