Return to Activity Algorithmus - Upper extremity

The Return to Activity Algorithm (RTAA®) for the upper extremity structures active rehabilitation after upper extremity injuries. It consists of a function-based test battery, which is directly associated with four levels (I-IV). Two tests are assigned to each level. First, possible compensations in the functional range of motion concerning the upper quadrant are evaluated (open chain) followed by the evaluation of the stabilizing and absorbing functions of the upper extremity (closed chain).

The levels build on each other, gradually increasing functional motor demands and required dynamic and static control in the performance of basic functions. To assess whether the patient has successfully completed each test, the result is then compared in terms of quality and quantity with the result of the unaffected extremity. The test results allow the therapist to derive direct training-therapeutic consequences and create a baseline for the selection of an appropriate training and therapy program for the patient.
