Active exercise is an exercise in which the patient exerts force to complete an action, e.g. standing up from the bed. The Physiotherapist is typically a supervisor and provides little to no assistance to the patient unless a problem arises i.e. fall. OR The movement performed within the unrestricted ROM controlled by the voluntary contraction of the muscle is known by Active Movement in Physiotherapy. Classification of Active Movement 1- Active assisted exercise: In which assistance is provided by an outside force, either manual or mechanical when muscle strength is inadequate to complete the motion. 2- Active free exercise: In which the voluntary contraction of the muscle can perform full ROM against gravity. 3- Active resisted exercise: In which the voluntary contraction of the muscle is resisted by an outside force.
