Lumbar radiculopathy is diagnosed by HK chiropractors using a physical examination and a review of the patient’s medical history. The physical examination will include a number of tests to measure range of motion and reflexes in the affected area, as well as tests to determine whether there is lower back pain or muscle spasm. Imaging tests, such as MRI scans or X-rays, may be used in specific cases (for example, severe symptoms or lack of improvement) to support the diagnosis.
