Final answer:
The term for range of motion when performed by the patient is called 'active'. It is used by physical therapists to assess a patient's strength and flexibility in order to develop personalized rehabilitation plans. Therefore, the correct option is c.
Step-by-step explanation:
The term for range of motion (ROM) when it is performed by the patient is active. During an active range of motion, the patient moves their own joints through the full movement to assess flexibility and strength. Compared to passive ROM, where a physical therapist or another person moves the joint, active ROM provides a good indication of the patient's ability to move and control their limbs post-injury. For instance, if a patient had an injured shoulder from kayaking, the physical therapist would assess the shoulder's ROM by asking the patient to perform movements such as abduction, adduction, circumduction, and flexion-extension of the arm. This assessment helps in creating a personalized physical therapy plan that addresses the specific impairments of the joint.
