Passive ankle dorsiflexion at the end of the SLR (Bragard test) is more sensitive, but can also remain normal in some cases of sciatica. However it is not perfect, and is not always well performed or interpreted. The Lasègue test is the most popular method, which starts with the straight leg-raising test (SLR). Sciatica may be confirmed if pain relief occurs.Diagnosis of sciatica mainly relies on pain reproduction by stretching of the lumbar roots since neurological examination and medical history are usually not sufficient to guarantee diagnosis. A diagnostic nerve block involves an anesthetic solution being injected around the sciatic nerve root(s) to numb the pain.A myelogram, electromyography (EMG), or discogram may also be performed.

Medical imaging tests may include X-rays, MRI, or CT scan.Slumping forward at the hip helps determine where pain bgins. A slump test includes an individual sitting upright with the hands behind the back. A straight leg raise (SLR) test may be performed, in which the individual lies on the back as the physician slowly raises each leg. Individuals will likely be asked to walk normally, walk on the toes or heels, and rise from a squatting or sitting position. A physical examination will evaluate range of motion, muscle strength, and reflexes.It also includes any injury (previous or current) of the back or hip area, muscle spasms or cramps in the pelvic region, and leg strength. A medical history reviews the pain onset, type (e.g., shooting, burning, etc.) and duration.Questions may include the level of pain experienced, movements or activities that worsen or relieve pain, and location of the pain.Medical imaging tests and a diagnostic nerve block may also be conducted if necessary. A physician will ask questions, obtain a medical history, and complete a physical examination. Diagnosing sciaticaĭiagnosing the underlying cause of sciatica is essential in managing pain and implementing an appropriate treatment plan. It is most commonly the result of a herniated or slipped disc, bone spurs, or spinal stenosis.

Sciatic nerve pain radiates from the lower back, into the buttocks, and down the legs. Sciatica, or sciatic nerve pain, refers to pain that occurs when the sciatic nerve root in the lower back becomes compressed, irritated or inflamed.
