Introduction[edit | edit source]
This test was designed to assess radicular pain, specially at the C4-C6 nerve roots. It is otherwise known as the shoulder abduction test. This test can be suggestive of cervical nerve involvement, but however isn't diagnostic of it. [1][2]
History[edit | edit source]
Dr John Bakody, a neurosurgeon developed this technique in 1977 and published his findings in Surgical Neurology [3].
Purpose[edit | edit source]
It is used to diagnose cervical radiculopathy and is as definitive as the spurling's test, but is less painful. It can also be used in case of a herniated disc pathology, spinal nerve root compression, or acute neck pain which may be neural related.
Procedure[edit | edit source]
The subject could be sitting or lying down. The upper limb is actively or passively raised above the head with the palm of the hand touching the head.
Interpretation[edit | edit source]
Positive sign: Reduction in symptoms with the painful arm placed on top of the head. The suggested mechanism includes reduction of pain as the traction force to the nerves and the lower brachial plexus trunks are relieved. With the arm hanging at the side of one's body, the mechanical traction acting on the nerve increases, thus increasing symptoms. [4][5]
Negative sign: Increase in the symptoms when the patient's hand is placed on the head. These symptoms are probably increased due to inter-scalene muscle compression. Thus placing the hand could be termed positive for inter-scalene compression and negative for Bakody sign.[5][4]
Here are 2 videos demonstrating the Bakody's test:
