Comprehensive rehabilitation of patients after burn injury requires the organized application of sound, recognized principles. The basic concerns are the prevention of loss of joint motion, loss of muscle mass, and the prevention of anatomic deformities. Important considerations are starting the rehabilitative program as early as possible after injury and avoiding techniques that unduly immobilize the patient or parts of the body. The use of early active motion to the patient and all movable joints, along with appropriate positioning while at rest, is crucial to a successful program. Passive exercising along with the use of restraints and splints is necessary in certain patients.
