Strength Isometric Test: Hip Abduction

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

1. Ask the client to adopt a side lying position on a massage table. Ensure their top leg is out straight and the bottom leg flexed to roughly 90 degrees at the knee and about 45 degrees at the hip.
2. The client can either cross their arms, or use their top arm to grip onto the edge of the table in the name of extra stability. 
3. Ensure the client is lying directly on their side in a neutral position, directly over their greater trochanter. Then, ask the client to bring their hip up into a neutral position so that they are in roughly 0 degrees of hip abduction.
4. Take the Muscle Meter and place it just above the client’s lateral malleolus.
5. Ensuring the Muscle Meter is held close to the practitioner’s body, queue the client to abduct their hip as best they can, holding for 2-3 seconds.
6. Once peak force production is achieved, hit save on the Measurz app and compare to the other side.

Normative data for hip abduction 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 abduction strength in adults:

• For males, the normative value for hip abduction strength is around 300-400 N (Newton).
• For females, the normative value for hip abduction strength is around 200-300 N (Newton).
