Sciatica Physiotherapy in Brampton

Sciatica is a symptom, not a diagnosis. The word describes pain radiating along the distribution of the sciatic nerve or one of its tributaries - typically from the buttock down the posterior or lateral leg, sometimes into the foot. The underlying cause must be identified for treatment to succeed. Possible causes include: lumbar disc herniation (by far the most common cause in adults under 50; L4-L5 and L5-S1 are most frequently involved), lumbar spinal stenosis (the most common cause in adults over 60; central, lateral recess, or foraminal), piriformis syndrome (sciatic nerve entrapment by the piriformis muscle - recent evidence suggests "deep gluteal syndrome" is a more accurate term because multiple structures can entrap the nerve), facet joint arthropathy with foraminal narrowing, sacroiliac joint dysfunction (referred rather than truly radicular), spondylolisthesis, tumor or infection (rare but must be screened), and intrapelvic pathology (endometriosis, pelvic tumor, pelvic-floor hypertonicity) in select presentations.

Prognosis for sciatica is strongly favourable with appropriate conservative care. The Weber 1983 long-term follow-up trial, the Peul 2007 SPORT trial, and the 2020 North American Spine Society (NASS) Evidence-Based Clinical Guidelines all converge on a consistent message: approximately 60-90% of disc-herniation-driven sciatica resolves within 6-12 weeks of appropriate conservative care without surgery. Surgery provides faster symptom relief but no meaningful long-term outcome difference at 1-2 years in most patients. Surgery is reserved for progressive neurological deficit, cauda equina syndrome (a surgical emergency), or intolerable pain despite 6-12 weeks of optimal conservative care.

Evidence-based physiotherapy for sciatica combines multiple techniques. McKenzie Mechanical Diagnosis and Therapy (MDT) uses directional-preference testing to identify movements that centralize the pain (reduce leg pain, move it proximally); Long 2004 and Albert 2012 RCTs support MDT's effectiveness. Neural mobilization (nerve gliders and tensioners; slump slider, SLR slider) improves nerve mobility and reduces nerve root sensitization - Basson 2017 meta-analysis (40 studies) demonstrates effectiveness. Lumbar spinal manipulation and mobilization are supported by Gudavalli 2016 RCT and recent Cochrane updates for subacute and chronic low back pain with and without radicular features. Graded core and hip stabilization (progressive loading, avoiding symptom provocation) addresses motor-control deficits. Cognitive functional therapy (CFT, O'Sullivan 2018 Lancet) addresses pain-related fear and avoidance, which predict chronicity more than any biomedical variable.

• Pain radiating from the lower back or buttock into the leg - this is the cardinal symptom; unilateral leg pain is more common than bilateral.
• Dermatomal numbness or tingling in an L4, L5, or S1 distribution (medial leg/great toe L4; lateral leg/dorsal foot L5; posterior leg/lateral foot S1).
• Myotomal weakness - hip flexion (L2-3), knee extension (L3-L4), ankle dorsiflexion/heel walking (L4-L5), great-toe extension (L5), plantarflexion/toe walking (S1).
• Pain worse with sitting, forward bending, coughing, sneezing, or Valsalva - classic disc-driven sciatica.
• Pain worse with walking and extension, relieved by flexion or sitting - classic lumbar stenosis neurogenic claudication.
• Positive Straight-Leg Raise (SLR) at <60 degrees reproducing leg symptoms (L5/S1 roots) or positive Slump test.
• Positive femoral nerve stretch (reverse SLR) - anterior thigh pain reproduced with prone knee flexion (L2-4 roots).
• Post-MVA leg pain - radicular symptoms following a motor vehicle accident; covered under SABS.
• Chronic buttock pain with leg radiation with negative lumbar tests but positive piriformis testing (Pace sign, FAIR test, active piriformis test) - deep gluteal syndrome / piriformis involvement.
• Post-surgical recurrent sciatica - 5-15% of patients have recurrent radicular symptoms after lumbar decompression or discectomy.
• Failed conservative care at another clinic - often the original plan missed directional preference, neural mobility, or neuromuscular control components.
• Pre-surgical second opinion and conservative trial - many patients are told they need surgery but have not yet had an evidence-based conservative trial.

Red-flag screening first (every first visit): before treatment begins we rule out conditions requiring urgent medical attention - cauda equina syndrome (saddle anaesthesia, new bowel/bladder dysfunction, bilateral leg weakness - an emergency requiring immediate ED referral), progressive neurological deficit (worsening motor weakness, developing new dermatomal numbness - warrants urgent surgical consult), signs of spinal fracture (significant trauma history, severe midline tenderness), signs of infection (fever, recent IV drug use, immunocompromised state), and signs of malignancy (unexplained weight loss, history of cancer, night pain unrelieved by rest, age >50 with new-onset pain).

Clinical assessment: detailed history (onset, trauma, prior episodes, pain pattern and diurnal variation, aggravating and easing factors, functional impact, yellow flags per Orebro Musculoskeletal Pain Screening), full neurological examination (dermatomes, myotomes, deep tendon reflexes, pathological reflexes such as Babinski and Hoffmann, clonus), orthopaedic testing (SLR, Slump, Bowstring, Femoral nerve stretch, crossed-SLR), lumbar range of motion with directional-preference testing (McKenzie MDT - repeated end-range flexion, extension, side-gliding), palpation of lumbar segments, hip range of motion and special tests (FADIR, FAIR, active piriformis test to screen for deep gluteal syndrome), and baseline outcome measures (Oswestry Disability Index, Numeric Pain Rating Scale at rest and with activity, Patient-Specific Functional Scale). Imaging is not routinely indicated for first-episode acute sciatica without red flags - NASS and Choosing Wisely recommend reserving MRI for cases with red flags or persistent symptoms despite 4-6 weeks of appropriate conservative care.

Treatment (evidence-based, individualized to directional preference and sub-type):

Disc-driven sciatica with extension directional preference (70-80% of lumbar disc cases): McKenzie repeated extension exercises performed 5-7 times per hour on the first several days, progressing to standing extension and dynamic extension-in-rolling patterns; this centralizes pain rapidly in responders.

Flexion-directional preference (stenosis, select disc cases with annular tears): flexion-based exercises, unloaded flexion, hip flexor stretching, pelvic tilt progressions.

Neural mobilization: slump slider and tensioner; SLR slider and tensioner; progressive loading to restore nerve mobility and reduce sensitization.

Lumbar manual therapy: lumbar grades III-IV mobilizations, muscle energy techniques, high-velocity low-amplitude manipulation where indicated and safe per clinical prediction rules (Flynn 2002).

Progressive core and hip stabilization: dead bug, bird dog, side plank, glute bridge, progressive loading; avoidance of symptom-provocative positions in the acute phase.

Graded functional rehabilitation: squat, deadlift, lifting mechanics, return to running, return to sport - progressive load management with symptom-guided progression.

Pain neuroscience education and cognitive-functional therapy for patients with fear-avoidance beliefs, catastrophizing, or chronic symptoms (O'Sullivan 2018 Lancet).

Adjuncts where indicated: spinal decompression traction (confirmed disc herniation with radiculopathy not responding to directional preference alone), Class IV laser / photobiomodulation, dry needling of secondary myofascial trigger points (quadratus lumborum, gluteus medius, piriformis), acupuncture, TENS for symptom management.

Typical course: acute sciatica (<4 weeks duration) with directional preference responds within 4-8 visits over 4-8 weeks. Subacute and chronic sciatica (>3 months) typically requires 8-16 weeks with graded exposure, neuromuscular retraining, and targeted psychological strategies. Failure-to-respond by session 8-12 with active rehab triggers re-evaluation, imaging referral, and/or surgical consultation where appropriate.

Coverage: billed under the physiotherapy benefit; direct billing to all major Canadian extended health insurers. WSIB if the sciatica relates to a workplace injury. MVA-SABS if related to a motor vehicle collision (post-MVA radiculopathy is common and treatable under the OCF-18 Treatment Plan). No doctor's referral required in Ontario.
