Arm Squeeze Test
Arm Squeeze Test is used to distinguish Cervical Nerve Root Compression from Shoulder Pain.
How do you perform the Arm Squeeze Test?
- The patient is sitting and the examiner behind him.
- The examiner squeezes the middle third of the patient’s upper arm with thumb on patient’s triceps and fingers on patient’s biceps with moderate compression (5.9 to 8.1 kg).

What does a positive Arm Squeeze Test mean?
Arm Squeeze Test positive if patient reports 3 points or higher on visual analog scale (VAS) with pressure on middle third of upper arm compared with acromioclavicular joint and subacromial area.
Accuracy
A study on 305 patients with cervical nerve root compression, 903 patients with rotator cuff tear, and 350 healthy volunteers founds that the sensitivity and specificity of this test was:
- Sensitivity: 96%
- Specificity: 96 %
The diagnosis of cervical nerve root compression (C5-T1) was based on clinical examination, electromyography, x-rays, and MRI.
The Arm Squeeze Test may be useful to distinguish cervical nerve root compression from shoulder disease in case of doubtful diagnosis.
A positive result to this test may lead to cervical etiology of the shoulder pain.
Note
A visual analog scale (VAS) consists of a line, often 10 cm long, with verbal anchors at either end (e.g., “no pain” on the far left and “the most intense pain imaginable” on the far right). The patient places a mark at a point on the line corresponding to the patient’s rating of pain intensity.
The VAS has often been recommended as the measure of choice for assessment of pain intensity.
