Sciatica: Clinical Insights and Multidisciplinary Care
Understanding the Causes, Diagnosis, and Treatment of Sciatic Nerve Dysfunction
At Corrective Spinal Rehab, we approach sciatica not as a symptom to be masked, but as a complex neuro-orthopaedic condition requiring precise assessment and integrated clinical intervention. Our multidisciplinary team, including licensed physiotherapists (PT), a Doctor of Physical Therapy (DPT), a Doctor of Chiropractic (DC), and a Doctor of Osteopathy (DO), collaborates to deliver advanced diagnostics and evidence-based treatment tailored to each patient's anatomical and neurological profile.
Q: What Is Sciatica?
Sciatica refers to neuropathic pain and neurological symptoms caused by irritation or compression of the sciatic nerve—the body’s longest and thickest peripheral nerve. Originating from the lumbosacral plexus (L4-S3), the sciatic nerve innervates the posterior thigh and extends distally to the lower leg and foot.
This condition typically arises from:
-
Intervertebral disc herniation (prolapsed disc)
-
Nerve root compression from spinal stenosis
-
Piriformis syndrome (entrapment within the piriformis muscle)
-
Pelvic misalignment or sacroiliac joint dysfunction
-
Segmental spinal instability, including spondylolisthesis
-
Muscle hypertonicity, particularly in the gluteal or paraspinal musculature
Other contributing factors may include:
-
Prolonged sedentary postures and poor ergonomic habits
-
Improper lifting mechanics
-
Pregnancy-related pelvic strain
-
Obesity-induced axial loading
-
Degenerative disc disease and facet joint arthropathy


Symptoms of Sciatica
-
Sciatica is often unilateral, although bilateral presentations may occur in more complex cases. Common clinical features include:
-
Radiating lumbosacral pain that follows the dermatomal path of the sciatic nerve
-
Gluteal pain with or without posterior thigh discomfort
-
Burning, tingling, or paraesthesia down the posterior leg
-
Motor weakness affecting hip extension, knee flexion, or ankle dorsiflexion (depending on the affected nerve root)
-
Myofascial stiffness, limiting straight leg raise (SLR) or functional mobility
-
Numbness or altered sensation in the lower limb
-
Shooting pain that worsens during standing or transitional movements
-
Hip or pelvic pain, often linked to biomechanical dysfunction
-
Difficulty lifting the leg due to neuromuscular inhibition or inflammation
-
​Q: How Is Sciatica Diagnosed at Corrective Spinal Rehab?
-
A precise diagnosis begins with a comprehensive initial physiotherapy evaluation, which includes:
-
Postural and biomechanical analysis using digital imaging
-
Manual palpation to identify segmental restrictions and muscular imbalances
-
Inflammatory screening through soft tissue evaluation
-
Neurological testing, including reflex, strength, and dermatomal sensory assessments
-
Functional movement testing to assess compensatory patterns and joint loading
-
-
A follow-up session focuses on correlating clinical findings with diagnostic images to establish a root-cause diagnosis—allowing us to treat the origin, not just the symptoms.
Our Multidisciplinary Approach to Sciatica Treatment
-
At Corrective Spinal Rehab, we specialise in restoring structural integrity and functional neurology through tailored interventions that address the mechanical and neurophysiological components of sciatic pain.
-
Key elements of our protocol include:
-
Orthopaedic manual therapy to correct vertebral and pelvic alignment
-
Myofascial release and targeted soft tissue therapy to reduce muscular tension
-
Spinal decompression and traction therapy to alleviate nerve root impingement
-
Functional rehabilitation exercises to improve motor control, proprioception, and pelvic-lumbar stability
-
Neurodynamic techniques to restore sciatic nerve mobility and reduce neural mechanosensitivity
-
Postural re-education and ergonomic training to prevent recurrence
-
-
Restoring spinal and pelvic alignment reduces abnormal biomechanical stress and inflammatory mediators, thereby decreasing compression on the sciatic nerve. As the neural structures decompress, neuroplastic recovery and improved afferent-efferent communication promote tissue healing, pain resolution, and optimal functional capacity.
