Sciatica Physiotherapy in West Perth
Sciatica is one of the most common presentations we see at PhysioLogix — and one of the most mismanaged. Rest and painkillers get people through the acute phase but don't address what's driving the nerve irritation. That's where physiotherapy makes the difference.
What is Sciatica?
Sciatica is pain caused by irritation or compression of the sciatic nerve — the longest nerve in the body, running from the lower back through the buttock and down the back of the leg, sometimes as far as the foot. The term describes a symptom rather than a diagnosis, which means identifying the source of the nerve irritation is the first and most important step in treating it effectively.
Sciatica does not always involve lower back pain. Some patients present with buttock and leg symptoms only, with no significant back pain at all — and this distinction matters because it affects both diagnosis and treatment.
Symptoms of Sciatica
Sciatica symptoms vary depending on the level of nerve involvement and the degree of compression or irritation. Common presentations include:
Sharp, shooting pain running from the lower back or buttock down the back of the leg — often described as an electric shock sensation. Tingling, numbness, or burning in the leg, calf, or foot. Muscle weakness in the leg, ankle, or foot in more significant presentations. Pain that worsens with sustained sitting, coughing, sneezing, or changes in posture.
What Causes Sciatica?
The two most common causes are disc-related compression and piriformis-related nerve irritation — and distinguishing between them determines how the condition should be treated.
Disc herniation or bulge — when an intervertebral disc bulges or herniates, it can compress the adjacent nerve root in the lumbar spine, producing classic sciatic symptoms down the leg. This is the most frequent cause of true sciatica and is commonly associated with lower back pain alongside the leg symptoms.
Disc herniations can also result from the sudden spinal loading of a motor vehicle accident and may be covered under your car accident insurance. Sciatica caused by disc injury or prolonged postural loading at work is one of the more common WorkCover presentations we manage. If your sciatica developed through your work, you may be able to access physiotherapy under your Workers Compensation.
Piriformis syndrome — the sciatic nerve runs beneath or occasionally through the piriformis muscle in the buttock. When this muscle becomes tight or in spasm, it can compress the nerve and produce sciatica-like symptoms without any lumbar disc involvement. This presentation is often missed when the lumbar spine is treated in isolation.
Other causes — spinal stenosis, facet joint inflammation, and less commonly tumour or infection can also produce sciatic symptoms. If your symptoms are not responding as expected to physiotherapy treatment, further investigation will be recommended.
Do I Need a Scan?
Not usually. Sciatica is diagnosed clinically through a thorough assessment of your history, symptoms, and a series of physical tests that identify where the nerve is being compromised. Most presentations can be assessed and treated without imaging.
If your symptoms are severe, include significant neurological deficits such as progressive weakness or loss of bladder or bowel control, or fail to improve after an appropriate course of physiotherapy, further medical investigation including MRI will be recommended. We will advise you clearly if this is the case.
How We Treat Sciatica at PhysioLogix
Treatment is structured around three phases that progress as your symptoms improve. The pace of progression depends on your presentation and how you respond — not a fixed timeline.
Early stage — acute symptom management. The initial focus is reducing pain and nerve irritation. Treatment includes manual therapy to the lumbar spine and hip, soft tissue release to address muscle guarding and spasm, dry needling where deep muscle tension is maintaining the nerve compression, and gentle nerve mobilisation exercises to restore sciatic nerve mobility without aggravating symptoms. The goal is meaningful pain reduction and restoring basic movement.
​
Mid stage — restoring mobility and building strength. As acute symptoms settle, treatment progresses to restoring lumbar and hip range of motion and beginning the strength work that prevents recurrence. Exercises become more dynamic, targeting the muscles of the lower back, glutes, and hip that support spinal stability and reduce load on the affected disc or nerve root.
Late stage — consolidation and prevention. Once pain is well controlled and movement is restored, the focus shifts to building the capacity to handle daily activities and, where relevant, return to training or sport without re-aggravation. Core stability, hip strength, and load management are central to this phase.. For patients who want a structured and supervised environment to progress their rehabilitation, Clinical Reformer Pilates is particularly effective in this phase for building the core stability and lumbar strength that prevents recurrence.
Frequently Asked Questions
How long does sciatica take to resolve with physiotherapy?
This varies significantly depending on the cause and severity. Acute sciatica caused by a disc bulge typically improves meaningfully within four to eight weeks of structured physiotherapy. Chronic or more severe presentations take longer. Most patients notice a meaningful reduction in symptoms within the first few sessions.
Can sciatica resolve without surgery?
Yes — the vast majority of sciatica cases resolve with conservative management including physiotherapy. Surgery is rarely required and is typically only considered when there are significant neurological deficits, such as progressive weakness or loss of bladder and bowel function, that are not responding to conservative treatment.
Do I need a referral to see a physiotherapist for sciatica?
No referral is required. Book directly online using the book an appointment button below or call 0450 075 955.
Where is PhysioLogix located?
6/567 Newcastle Street, West Perth WA 6005. We regularly see patients with sciatica from Subiaco, Leederville, North Perth, Nedlands, Mount Hawthorn, and across the inner Perth suburbs. Free street parking is available directly outside with 3 hour time limits during clinic hours.
Should I rest with sciatica?
Complete rest is not recommended. Gentle movement and walking are generally beneficial in the early stages. The right activity level depends on your specific presentation — we will advise you on this at your first appointment.
Can sciatica resolve without physiotherapy?
Dealing with sciatica and not sure where to start? Call us on 045 007 5955 and we'll give you a straight answer.
Mild sciatica can improve without treatment, particularly if the aggravating posture or activity is identified and modified. However, sciatica that involves significant nerve compression, neurological symptoms such as pins and needles or weakness, or has been present for more than a few weeks rarely resolves without structured physiotherapy. Early treatment consistently produces better outcomes than waiting.
