How to diagnose sciatic nerve pain?

Selective nerve block injections are considered an accurate and effective method in diagnosing sciatic nerve pain. An anesthetic solution is injected around the sciatic nerve root (s) to numb the pain transmitted by the nerve.

These techniques allow the physician to guide the needle to the accurate location where the medication needs to be deposited. If pain relief is experienced, sciatica may be confirmed.

Note: A physician has a number of testing procedures that can be ordered to diagnose the cause of sciatica. These include X-Ray to assess osteoarthritic bone spur encroachment in the IVFs, MRI or CT Scan to assess pathologic disc or other soft tissue encroachment in the IVF or central canal, and electrophysiologic testing in which conduction of the sciatic nerve is directly assessed.

How to assess sciatica?

Physical examination assessment of sciatica begins with straight leg raise (SLR). Straight leg raise is performed by passively raising the lower extremity of the supine client/patient by flexing the thigh at the hip joint with the knee joint extended. This places a tensile force upon all posterior soft tissues, including the sciatic nerve, stretching them longer. If the sciatic nerve is already compressed in the intervertebral foramen (IVF) (or the central canal), then stretching it longer will pull it taut against the space-occupying lesion (bulging/herniated disc or bone spur), thereby increasing the referral symptoms into the lower extremity. For this reason, a positive finding for SLR assessment of sciatica requires referral into the lower extremity. This test would then be repeated for the other side.

Why is it important to assess the piriformis for tightness that might compress against the sciatic nerve?

Because sciatica might be caused by piriformis syndrome, it is important to also assess the piriformis for tightness that might compress against the sciatic nerve. This can be done via palpation and by assessing its ability to lengthen by stretching it.

What is a positive slump test for sciatica?

A positive finding for slump test for sciatica requires referral into the lower extremity. This test would then be repeated for the other side.

How to do a seated lumbar spine test?

Can sciatica cause nerve pain?

Sciatica causes symptoms into the sciatic nerve distribution in the lower extremity. Therefore, any condition that causes symptoms into this region could potentially be mistaken for sciatica. Many conditions can do this. Foremost amongst these is myofascial trigger point referral or referral from an irritated sacroiliac joint. Therefore, before being confident in the assessment of sciatica, it is important to rule out these other conditions. Local pain in the lower extremity caused by tight musculature, sprains, and strains, might also be mistaken for sciatica. And because sciatica can cause numbness into the foot, diabetes and other conditions that cause peripheral neuropathy must also be differentially assessed.

Is sciatica a condition?

In a sense, sciatica is not a condition but rather a sign of another condition: a space-occup ying (nerve compression ) condition that is compressing the sciatic nerve. Therefore, successful assessment/diagnosis of sciatica depends upon successfully assessing the underlying cause of the sciatic nerve compression.
