The rib lock extrusion test is often used to check the degree of slack in the ligament of the upper limb band and the space of the rib lock gap when the weight is heavy. Rib lock extrusion test: take a straight position, so that the patient will extend the shoulder joint backwards, similar to the military standing upright. Check for changes in the brachial artery pulse. In this examination, it must be noted that the patient's neck should not be overstretched, flexed or rotated.

Basic Information

Specialist classification: growth and development check classification: physical examination

Applicable gender: whether men and women apply fasting: not fasting

Analysis results:

Below normal:

Normal value:
no

Above normal:

negative:
The test result was negative. In the normal population, after the intensive traction, the brachial artery pulsation completely disappeared by 22%, significantly reduced by 37%.

Positive:
The test result was positive, indicating that the ligament of the upper limb of the examinee was slack, and the gap of the rib lock was easy to become small when the weight was heavy. The biggest disadvantage of this check is that the result varies with the size of the examiner.

Tips: Check your relaxation and follow the doctor's instructions. Normal value
