Question

range of motion is normally greater than range of motion. a) active, passive b) isometric/isotonic c) passive, active d) isometric/isokinetic

Explanation:

Passive range of motion (PROM) refers to the movement of a joint that is achieved by an external force (such as a therapist or a machine), without any active muscle contraction from the patient. Active range of motion (AROM) is the movement of a joint that is produced by the patient's own muscle contraction. Since in passive movement, there is no limitation from muscle resistance (as the muscles are relaxed), the passive range of motion is normally greater than the active range of motion. Isometric (muscle contraction without joint movement) and isotonic (muscle contraction with joint movement) are types of muscle contractions, not directly related to the comparison of ranges of motion in the context of the question. Isokinetic is a type of muscle contraction where the speed of movement is constant.

Answer:

C. Passive, Active
