Answer:
d. fully moving the muscles without locking your joint.
Step-by-step explanation:
An example of moving properly through range of motion is fully moving the muscles without locking the joint. This is because joint locking can be a symptom of pathology in a joint, such as damage of ligaments, a lose body present inside the joint or a meniscal tear. A natural, healthy range of motion requires people to be able to fully flex and extend a joint.
