How to Conduct the Standing Calf Raise Test to Measure Lower Extremity Strength

Assessing a client’s lower extremity strength is essential for evaluating mobility and overall functional health. One reliable tool for this assessment is the Standing Calf Raise Test, which measures force production in the plantar flexors surrounding the ankle joint. By conducting this test, you gain valuable insights into a client’s strength and potential areas for improvement. Here’s a step-by-step guide to performing this test, along with the recommended force values relative to body weight.

 

Equipment Needed

For accuracy, we recommend using the following equipment for the Standing Calf Raise Test:

  1.   Muscle Meter and Tester – Provides reliable measurements of force output.
  2.   Two Large Carabiners – Attach to either end of the Muscle Meter.
  3.   Chain and Smaller Carabiner – Typically included in the Muscle Tester package.
  4.   Squat Belt – Worn around the client’s waist.
  5.   Stability Stick (Optional) – Helps the client maintain balance during the test.

 

Step-by-Step Procedure

  1.   Prepare the Client

Secure the squat belt around your client’s waist and ensure it’s comfortable. Attach the chain to the belt using the smaller carabiner.

  1.   Warm-Up and Practice

Allow the client to become familiar with the setup by performing 2–3 practice calf raises. This helps them feel comfortable and improves test reliability.

  1.   Perform the Calf Raise Test

Instruct the client to perform a double-legged calf raise, lifting their heels off the ground and holding at the top for 2–3 seconds before lowering. Repeat this sequence three times, recording the highest score achieved.

 

Interpreting Results: Recommended Force Values

To assess strength relative to the client’s body weight, use the following force benchmarks as reference points:

  •   Female Clients: Aim for at least 0.84 Newtons (N) per kg of body weight.
  •   Male Clients: Aim for at least 0.97 Newtons (N) per kg of body weight.

These benchmarks are based on normative data from Buckinx et al. (2019), which provides valuable reference points for assessing isometric strength and its relation to functional autonomy.

By following this approach, you can confidently assess lower extremity strength, providing data-driven insights into your client’s mobility and functional health.
