Understanding the Hyperabduction Test (Wright's Test) Assessment
To detect vascular compression of the **subclavian artery** due to entrapment under the **Pectoralis Minor tendon** (Pec Minor Syndrome).
Watch How It's Done
How do I start?
Patient is sitting. Examiner palpates the radial pulse.
What happens?
The arm is passively moved into a position of **maximal hyperabduction** (above the head) and **full external rotation**. The position is held for 1 minute.
In Plain English
What Does a Positive Result Mean?
A **diminution or disappearance of the radial pulse** and/or the reproduction of the patient's hand/arm symptoms.
Helpful Tip:
Hyperabduction stretches the Pectoralis Minor, which can pinch the neurovascular bundle against the coracoid process.
Safety First
This guide is to help you understand what happens in a clinic. Do not try to diagnose yourself. If you have severe pain, swelling, or cannot put weight on your leg, please visit an urgent care center or your doctor immediately.
Other Thoracic Outlet Tests
Allen Test (for TOS)
To detect vascular compression of the **subclavian artery** as it passes under the Pectoralis Minor muscle (Pec Minor Syndrome, or Hyperabduction Syndrome).
Costoclavicular Test (Military Brace Test)
To detect compression of the neurovascular bundle between the **clavicle** and the **first rib** (Costoclavicular space).
