Which action is performed by the client without assistance from the practitioner?

The client performs active range of motion independently, which means they are able to move their joints and limbs without any assistance from the practitioner. This type of movement is crucial for maintaining and improving flexibility and strength, as it directly engages the muscles that control the movement. By using their own power, the client actively engages in the exercise, promoting improved muscle coordination, strength, and joint mobility.

In contrast, passive range of motion requires the practitioner to move the client’s joints and limbs without the client’s muscular engagement. Active assisted range of motion involves the practitioner providing some help or support while the client performs the movements, indicating that the client is not fully independent in the action. Isometric range of motion involves muscle contraction without joint movement, and this also does not reflect the client acting on their own initiative to move. Understanding these distinctions helps clarify why active range of motion is characterized by the client's independent action.
