Costoclavicular or Military Brace or Eden’s Test
Original Editor - Venus Pagare
Purpose[edit | edit source]
Test for presence of thoracic outlet syndrome.
Technique[edit | edit source]
Patient is standing. The examiner palpates the radial pulse and then draws the patient's shoulders down and back as the patient lifts their chest in an exaggerated "at attention" posture. A positive test is indicated by an absence or decrease in vigor of the pulse and implies possible costoclavicular syndrome. It is also positive if the client experiences an increase of neurologic symptoms into the upper extremity on that side. This test is particularly effective in patients who complain of symptoms while wearing a backpack or heavycoat.
Importance of Test[edit | edit source]
Patients with vascular types of thoracic outlet syndrome often describe their pain as a fullness, heaviness, clumsiness, or weakness in their arm. The patient may also have subjective complaints of swelling, either permanent or intermittent. When performing the Costoclavicular Brace Test, the examiner is placing the patient in a position that compresses the neurovascular bundle between the first rib and clavicle, thus resulting in a decrease in pulse strength. When performing this test, it is important to test the contralateral side as well to understand the patient's normal radial pulse.
Evidence[edit | edit source]
Demirbag et al compared MRI findings to postural maneuver tests for thoracic outlet syndrome. They recommend the military brace test with moderate support for use in clinical diagnostics of thoracic outlet syndrome.
