Does the knee raiser test require stabilization?

• A. Yes, full stabilization
• B. Stabilization only at pelvis
• C. No
• D. Stabilization is optional

Answer: (C)

The knee raiser test is about how much the leg can lift using the knee/hamstring muscles without forcing the pelvis to stay completely still. Stabilization isn’t needed here because the goal is to observe true leg mobility and any natural compensations, not to isolate the pelvis. If you actively stabilize the pelvis, you can artificially restrict movement or mask how the body compensates, which would distort the assessment. So, you let the pelvis remain in a natural position and focus on the leg’s ability to raise.
