Clinical Application of the Sahrmann Test
The Sahrmann Core Stability Test is distinct from traditional "abs" tests. It evaluates the patient's ability to dissociate limb movement from spinal position. Failing Level 1 is a primary clinical indicator of instability-related low back pain.
Interpreting the Results
- Level 0-1: Severe Motor Control Impairment. Patient cannot maintain TrA activation during basic breathing or minimal limb load.
- Level 2-3: Functional Core Stability. Patient can handle unilateral loads but lacks the eccentric control for bilateral leg lowering.
- Level 4-5: Elite Athletic Stability. High-level motor recruitment suitable for heavy lifting and impact sports.
Expert FAQ Section
What is the "10mmHg Rule"?
When using a Pressure Biofeedback Unit (PBU), the baseline is typically 40mmHg. If the pressure increases or decreases by more than **10mmHg**, it signifies a failure to maintain neutral spine stability.
Does a strong 'six-pack' help pass this test?
Not necessarily. Over-reliance on the Rectus Abdominis (the six-pack muscle) often leads to spinal flexion (arching into the mat), which causes a failure in the Sahrmann protocol.
