Purpose
[edit | edit source]
This test is a diagnostic tool used in the identification of Thoracic Outlet Syndrome (TOS)
It is also known as the “elevated arm stress test” or "EAST".
Clinically Relevant Anatomy[edit | edit source]
Please refer to the Thoracic Outlet Syndrome (TOS) page.
Technique
[edit | edit source]
Starting postion: [1]
- The patient has both arms in the 90° abduction-external rotation postion
- Shoulders and elbows are in the frontal plane of the chest
Execution:
- The patient is to open and close the hands slowly over a 3-minute period
Results if normal:
- Only forearm muscle fatigue and minimal distress
Possible symptoms if TOS is present:
- gradual increase in pain at neck and shoulder, progressing down the arm
- Paraesthesia in forearm and fingers
- In case of arterial compression: arm pallor with arm elevated, reactive hyperemia when limb is lowered
- In case of vernous compression: Cyanosis and swelling
- Inability to complete test, and patient drops arms in lap in marked distress, recognized as reproduction of usual symptoms
- Reproduction of the usual symptoms that involve the entire extremity!
Possible results if carpal tunnel syndrome is present:
- Numbness in first three fingers due to compression of nervus medianus
Possible results in case of cervical disc syndrome:
- Pain in neck and shoulder from holding arms elevated but minimal distress in arm or hand.
Possible results in case of orthopedic shoulder problems:
- Intolerable symptoms confined to shoulder area
Diagnostic accuracy:[2]
- Sensitivity: 84%
- Specificity: 30%
- PPV: 68%
- NPV: 50%
Reliability:
- Inter and intra-examiner reliability have not yet been found in literature.
