There really is no special test or diagnostic test, like an x-ray, for a frozen shoulder. The diagnosis is made by observation of the mobility of your shoulder. Usually, a painful loss of motion while lifting your arm forward, out to the side, and through rotation indicates a frozen shoulder.

A physical exam is usually enough to diagnose frozen shoulder, but your doctor may also order imaging tests such as X – Ray.
In some cases, your doctor might inject your shoulder with a numbing medicine to determine your passive and active range of motion. Frozen shoulder can usually be diagnosed from signs and symptoms alone. But your doctor may suggest imaging tests such as X-rays or an MRI to rule out other problems.

APLEY’S SCRATCH TEST :
The Apley scratch test is another useful maneuver to assess shoulder range of motion. In this test, abduction and external rotation are measured by having the patient reach behind the head and touch the superior aspect of the opposite scapula.

The Apley scratch test movement has two parts to it:
Step one:
It involves one arm abducting, and externally rotating with the fingers pointing down the spine reaching as far behind you as you can, like reaching to scratch your back.
Step two:
It involves the other arm adducting, and internally rotating with the fingers pointing up the spine, like reaching to put a bra strap on.
