Looking for information on diagnostic tests and how they work? Bad Backs have done the research and we've compiled our results for reference only.

X-ray (Radiography, plain film)

X-ray (Radiography, plain film)

Discogram

Discography is a procedure used to determine if the intervertebral discs are the source of a patient's pain. The test is usually done for patients with chronic back or neck...

Electromyogram (EMG)

Bone Scan

Bone scanning is extremely sensitive at detecting subtle stress fractures or bone tumours when they are invisible on plain x-rays. It is particularly helpful when it is unclear exactly where...
