Sciatica Treatment in East Brunswick, NJ: A McKenzie Method Approach

If you feel pain that travels from your lower back down through your buttock and into your leg, you may be dealing with sciatica.^[1] It is one of the most common reasons patients come to our clinic in East Brunswick. The good news is that sciatica often improves over time,^[2] and clinical guidelines recommend advice to help you self-manage and stay active, with exercise programs as one option to consider.^[3]

What Causes Sciatica?

Sciatica is not a diagnosis in itself; it is a description of symptoms, usually pain that travels from the lower back down into the leg.^[1] True sciatica comes from an irritated nerve root in the lower spine, and research suggests that both pressure on the nerve root and inflammation play a part.^[1] Common underlying causes of this kind of leg pain include:

• A herniated disc pressing on a nerve root, the classic cause of true sciatica^[1]
• Narrowing of the spinal canal (spinal stenosis), a common cause of back and leg pain in older adults^[4]
• Pain referred into the buttock or leg from structures in the lower back, without a pinched nerve. Many people call this sciatica too, but it is a different problem that can need different treatment^[1]

Because the source can vary, a careful assessment is an important first step. Telling nerve-root pain apart from referred pain matters because the two can need different treatment,^[1] and guidelines advise ruling out specific causes of back pain, such as infection, injury or inflammatory disease.^[3] Because many of our patients commute or work at desks throughout Middlesex County, we also look at how sitting and other everyday positions affect your symptoms.

When Should You See a Physical Therapist for Sciatica?

Many people wait, hoping the pain will simply fade. Sometimes it does, but not always: in a large UK study of adults who saw their family doctor with back-related leg pain, just over half had improved a year later (meaning their disability score had dropped by at least 30%).^[2] But if your symptoms have lasted more than a week or two, are getting worse, or are affecting your sleep, work, or daily activities, an evaluation is worthwhile.

Physical therapy is commonly used as a first-line, non-invasive treatment for sciatica,^[5] and experts agree that, unless there are severe or worsening nerve symptoms, treatment in the first 6 to 8 weeks should be non-surgical.^[1] That said, research on physical therapy for sciatica is still too limited and mixed to show clearly whether, or how much, it helps.^[5] Guidelines suggest considering surgery when non-surgical treatment has not improved pain or function and scans match the symptoms.^[3] For people with disc-related sciatica who are candidates for surgery, an operation can ease leg pain faster, but the evidence for this is of low to very low certainty and the advantage is negligible by one year.^[6]

Get emergency care right away if back or leg pain comes with numbness or altered feeling between your legs or around your bottom (the "saddle" area), or with new bladder or bowel problems. These are red flags for cauda equina syndrome, a medical emergency that needs urgent assessment and an MRI.^[7] Several guidelines also list new leg weakness as a warning sign.^[7]

The McKenzie Method Approach to Sciatica

At Spineck, we use the McKenzie Method (Mechanical Diagnosis and Therapy, or MDT). An MDT evaluation uses repeated movements and positions to look for a directional preference, a direction of movement that eases your symptoms, and for "centralization," where pain retreats from your leg back toward your spine. Not everyone has these responses: in research on people with back or neck pain, about two in three showed at least one of them.^[8] In people with back pain, centralization and directional preference are linked with a better outlook, although research has not shown that they predict who will benefit most from a particular treatment.^[8]

From there, we teach you a personalized set of movements you can do on your own, which puts you in control of your recovery. Guidelines recommend tailored advice that helps people self-manage back pain and sciatica at every stage of care.^[3] It is worth knowing that a structured exercise program seems to add only a little over simple advice: structured exercise eased leg pain slightly more than advice to stay active in the short term, with no clear difference in the long term,^[9] and in a small trial of people with disc-related sciatica, McKenzie exercises and guideline-based advice led to similar improvements after two years.^[10]

Sciatica vs. Herniated Disc: Are They the Same?

Not exactly. A herniated disc is one cause of sciatica, but not the only one.^[1][4] Sciatica describes the symptoms, while a herniated disc describes a specific structural change. This is why a careful evaluation matters: two people with similar leg pain may need different treatment plans.^[1]
