Range of motion assessment
Range of motion refers to how far a joint or body region can move. Range of motion assessment helps the therapist understand movement capacity, comfort, restriction, and possible tissue involvement. Massage therapists commonly use range of motion assessment to compare sides, identify movements that reproduce symptoms, and reassess change after the session.
There are three major types of range of motion assessment: active range of motion, passive range of motion, and resisted range of motion.
Active range of motion occurs when the client moves a joint using their own muscles. For example, the therapist may ask the client to slowly turn the head to the right and left, raise an arm overhead, bend forward, or flex and extend the ankle. Active range of motion shows what the client can do independently. It includes joint mobility, muscle strength, motor control, coordination, willingness to move, and pain response. Because the client controls the movement, active range of motion is often the safest first step.
Passive range of motion occurs when the therapist moves the client’s relaxed body part. For example, with the client supine, the therapist may gently move the client’s shoulder, hip, or neck within a comfortable range. Passive range of motion helps assess joint and soft tissue mobility without requiring the client’s muscles to create the movement. It must be done slowly, gently, and with consent. Passive motion is not appropriate in all situations, especially when there is acute injury, instability, severe pain, or medical precautions.
Resisted range of motion occurs when the client attempts a movement while the therapist provides gentle resistance. For example, the therapist may ask the client to lift the arm while the therapist lightly resists the motion. Resisted testing may provide information about muscle involvement, weakness, or pain with contraction. Massage therapists should use resisted range of motion only within their training and scope. It should not be aggressive, and it should stop if pain increases significantly.
During range of motion assessment, the therapist observes the quality of movement. Is it smooth or jerky? Is it hesitant or confident? Is there a sudden stop? Does the client hold the breath? Does the client compensate with another body part? Does one side move more freely than the other? These observations reveal more than the final distance of the movement.
The therapist may also notice end feel. End feel refers to the quality of resistance felt at the end of a passive range of motion. For example, the end of a movement may feel soft, firm, springy, empty, or blocked. A soft end feel may occur when muscle or soft tissue approximates. A firm end feel may occur when ligaments or joint capsules limit the movement. An empty end feel occurs when the client stops the motion because of pain before the therapist feels a clear tissue barrier. Massage therapists should treat end-feel assessment with caution and remain within scope. If end feel suggests serious restriction, instability, or unexplained pain, referral may be appropriate.
Range of motion findings can be recorded as qualitative or quantitative measurements. A qualitative measurement might be “right cervical rotation limited compared with left and produces pulling in left up
