How do you perform the arm squeeze test? How do you interpret it?
When there is NR compression, 1+ nerves of the arm are sensitive to moderate compression of the biceps and triceps area and should be more painful than other areas of the shoulder and upper arm.
A positive test hurts 3+ more (3/10 pain scale) or during the pressure on the middle third of the upper arm, compared with compressing the AC and anterolateral-subacromial areas.
Example: if shoulder hurt 1/10 but arm hurt 4/10 that suggests it may not be a shoulder problem, but a nerve problem that is from the neck.
