Strength Isometric Test: Hip Flexion

To test hip flexion isometric strength with a Muscle Meter, you can follow these steps:

1. Have the client adopt a supine position on a massage table with their legs out straight.
2. On the testing leg, ask the client to bring their leg up into approximately 20 degrees of hip flexion.
3. Once set, take the Muscle Meter and place it at the bottom of the client’s tibia. Queue the client to push up as hard as they can, holding for 2-3 seconds to achieve peak force output.
4. Upon completion, hit save on the Measurz app and compare to the other side.

Normative data for hip flexion strength with a Muscle Meter varies depending on the population being tested, the dynamometer used, and the specific testing protocol. However, here are some general normative values for hip flexion strength in adults:

• For males, the normative value for hip flexion strength is around 200-300 N (Newton).
• For females, the normative value for hip flexion strength is around 150-250 N (Newton).
