Biering-Sorensen Test: What It Measures and Why It Matters

At Vertex PT Specialists in Columbia, SC, we regularly use the Biering-Sorensen Test to evaluate lumbar endurance in athletes, active adults, and individuals recovering from low back pain. It’s a powerful tool to assess the isometric endurance of the back and hip extensors, helping us identify clients who may be at higher risk for developing nonspecific low back pain.

Whether you’re a CrossFit athlete, weightlifter, or weekend warrior, understanding your posterior chain endurance is key before returning to deadlifting, running, or any high-level physical activity.

What Is the Sorensen Test?

The Biering-Sorensen test (often referred to simply as the Sorensen Test) is a clinical assessment of the endurance of your lumbar spine extensors. Research supports its use in predicting the likelihood of future or recurring low back pain, especially in active populations.

How Is the Sorensen Test Performed?

You’ll need:

• A GHD machine (glute-ham developer), available in most gyms and performance clinics
• A timer
• A trained provider or clinician (preferably a physical therapist in Columbia, SC )

Instructions:

1. Position the patient face-down on the GHD in a horizontal prone position.
2. Cross arms over the chest and keep the chin tucked.
3. Make sure the upper edge of the iliac crest aligns with the pad.
4. Instruct the patient to brace the abs and squeeze the glutes to maintain a neutral spine.
5. Start the timer when they reach full position.
6. Stop the test when:
   The patient’s shoulders drop
   They can no longer hold position
   240 seconds (4 minutes) is reached
