Purpose of Test: To assess the impact of decreased intervertebral foraminal space on the patient’s symptoms.
Test Position: Sitting.
Performing the Test: Laterally flex the spine to the unaffected side. Apply an axial compression force through both shoulders. Repeat on affected side. Pain/symptom reproduction is a positive test.
Diagnostic Accuracy: Unknown.
Importance of Test: As disc height decreases and bone spurs accumulate, the space for nerves to enter and exit the vertebral canal gets smaller. Certain spine positions close that gap and put even more pressure on the nerves. This test tries to recreate those sensitive positions by compressing the vertebrae, thus, pressing down on the nerve if compromised.
Note: tests should only be performed by a properly trained health care practitioner.
