Muscle can move only if the resistance of gravity is removed. As an example, the elbow can only be fully flexed only if the arm is maintained in a horizontal plane |

Muscle strength is further reduced such that the joint can be moved only against gravity with the examiner's resistance completely removed. As an example, the elbow can be moved from full extension to full flexion starting with the arm hanging down at the side. |
