Children with physical disabilities usually lack of control over their environment due to limited mobility. The purpose of this article is to develop a frame of reference to help children with physical disabilities gain mastery over their environment. An entire frame of reference includes four components: theoretical base, function-dysfunction continua, behaviors indicative of function and dysfunction, and postulates regarding change. Theoretical base of this frame of reference is drawn from the theories of empowerment and social learning theory. Function-dysfunction continua are competencies identification, environmental analysis and strategies developing. Behaviors indicative function and dysfunction provide therapists guidelines and examples to identify problems. Postulates regarding change describe the practical methods which enable children with physical disabilities to control over their own environment.
