Jackson Compression test is a cervical spine examination procedure used to determine joint damage, meniscoid entrapment or muscle strain. It is a confirmatory test for cervical spine nerve root compression which causes neck pain.
Patient should be awake and cooperative for the Jackson Compression test.
- Patient should be seated for the procedure.
- The patient rotates her head to one side as the examiner applies a downward pressure over the head.
- The patient rotates her head to the opposite side and the examiner applies a downward pressure over the head.
- The examiner assesses the patient for any local or peripheral pain.
Positive Jackson Compression Test
There is positive Jackson Compression test when the following is seen:
- Increased localized pain; this could indicate joint damage, meniscoid entrapment or muscle pain.
- Increased peripheral pain; this could indicate pressure on nerve roots (IVF encroachment or radiculopathy).
Jackson Compression test may also elicit VBI-type symptoms since it also compresses the vertebral artery. VBI-type symptoms include dizziness, vertigo and nystagmus).
