Spring test = push down on L5 and determine whether or not it 'springs' (moves).
Spring test is POSITIVE when there is NO movement of L5. This indicates that L5 is flexed relative to the sacrum and suggests a backward sacral torsion (May also suggest a unilateral sacral extension or a bilateral sacral extension, however, I've mainly seen it used to confirm backwards torsion)
Spring test is NEGATIVE when L5 moves. This is generally a normal finding.
The test can also tell you if the sacral problem is physiologic or not. For example a L on R and a R on L, L on L, and R on R are all physiological issues. However if you have a Bilateral deep sulcus, this is NOT physiologic and therefor had to have been caused by some sort of trauma such as falling on your rump.
If you have a negative spring test you can already eliminate about 1/4 of the sacral dysfunctions.
You are testing the LS junction.
Positive: No spring: sacrum is extended or backward torsion or rotation for example (left on right or right on left)
Negative: there is spring or sacrum is flexed
What I usually do is have the patient breath in: this straightens the lumbar spine out and extends or counternutates the sacrum. There will be NO spring (negative) so you can see how that feels then have the patient breath out so you can compare. Hope this helps
