College of Massage Therapists of British Columbia (CMTBC) Practice Exam

Which type of physical assessment would be appropriate for evaluating capsular tightness?

1. Passive range of motion test

2. Active range of motion test

3. Functional movement screening

4. Neurological examination

The correct answer is: Passive range of motion test

The passive range of motion test is particularly effective for evaluating capsular tightness because it allows the practitioner to assess how much movement is available at a joint when the muscles are relaxed. This type of assessment isolates the joint capsule and surrounding structures from any active muscle contraction, providing a clearer picture of the capsular constraints on movement. When performing this test, the therapist moves the joint through its available range while the patient remains passive. If there is a restriction in movement that is felt as "end-feel," indicating that the joint's capsule is likely tight, this suggests capsular tightness. In contrast, active range of motion tests gauge the range of motion achievable by the patient through their own muscular effort, which can introduce variable factors like pain or weakness, making it less specific for detecting capsular restrictions. Functional movement screenings assess the body’s ability to perform movements that involve multiple joints and systems, which does not specifically isolate the joint capsule. Neurological examinations focus on nerve function and responses, rather than mechanical restrictions of joints, and are not suitable for evaluating capsular tightness.
