hi all,

The only way to do a test objectively is to have set parameters that you can measure.

Physiotherapy will always have an art component involved because of this reason - no matter what test you use...and because everyone is unique (even twins).

To measure either the APAS test (neuromuscular's test) or the "Stork Test" objectively, you would have to put markers into the bone to determine the direction of movements in 3 dimensions. And that would only give you direction of motion...how much motion is significant???

The Stork test has studies on reliability which support its use when it is a simple +/- result.

Do neuromuscular's test - it is simply hip ABD in the coronal plane at predetermined distances (which has the flaw of people having different leg lengths therefore not being comparable between patients unless they all have the same leg length). You then see if the pelvis as a unit twists.

It is simply a standing stretch of sorts - the tightest structures will lock up first causing a torsion or some other compensation of the body - when this occurs, you still have to work out what it is that caused the compensation...good luck!
