Why diagnosis matters for back pain

Lower back pain is a symptom, not a diagnosis. Saying someone has "lower back pain" tells us very little about what is actually wrong — which is why the same symptom in different people often requires completely different treatment. The three most common mechanical sources are distinct in how they present, what aggravates them, and how they respond to treatment:

  • Disc injury — typically worse with flexion (bending forward), prolonged sitting, coughing and sneezing. May refer pain into the leg (sciatica) if the disc is pressing on a nerve root.
  • Facet joint irritation — typically worse with extension (leaning back) and rotation. Often one-sided. Eases when the spine is slightly flexed.
  • Sacroiliac joint dysfunction — pain around the dimple area of the lower back, often worse with walking, rolling over in bed, or standing on one leg. Can refer into the buttock and upper thigh.

Treating all three the same way produces predictably poor results. Mechanical assessment — the kind performed at every initial appointment at our clinic — identifies which structure is the primary driver before any hands-on care begins.

Sciatica

Sciatica is pain that travels from the lower back into the buttock, thigh, calf or foot along the path of the sciatic nerve. It is almost always caused by compression or irritation of a lumbar nerve root — most commonly from a disc herniation at L4/5 or L5/S1, though spinal stenosis and piriformis syndrome can produce similar symptoms.

The clinical distinction between true neurogenic sciatica and referred pain from other lumbar structures matters significantly for how we treat it. Neurological testing at the first appointment — reflexes, straight leg raise, sensation and muscle strength — guides this distinction.

How we treat lower back pain at our Mooloolaba clinic

Treatment is selected based on what the assessment reveals, not a standard lower back protocol. Depending on the findings, your physiotherapy plan may include:

  • Specific manual therapy — joint mobilisation or manipulation targeting the affected level, soft tissue work for guarded muscles, and traction techniques where disc-related nerve root symptoms are present
  • Dry needling — for persistent muscle guarding and trigger points that are maintaining the pain cycle after the joint irritation has resolved
  • Motion IQ testing — objective measurement of lumbar range of motion at baseline and at progress reviews to track what is actually changing
  • Progressive exercise rehabilitation — loading the spine progressively through the range of motion it has been avoiding is the single most important factor in long-term recovery. We use our on-site rehab studio to supervise this component
  • On-site X-ray where indicated — if imaging will change the diagnosis or management plan, we can arrange this on the same day

Physiotherapy and chiropractic for back pain

At Absolute Health, physiotherapy and chiropractic are in the same building and work as a collaborative team rather than competing alternatives. For many lower back presentations — particularly those with a strong joint component alongside muscular and movement deficits — a coordinated approach produces better outcomes than either discipline working alone. If your assessment suggests you would benefit from both, that conversation happens at the first appointment, not after weeks of incomplete progress.

You can read more about the combined approach at absolutehealth.net.au.

How many sessions will I need?

Acute mechanical back pain that has not become chronic typically responds within four to eight physiotherapy sessions when the right structure is being treated. Disc-related sciatica takes longer — particularly if neurological signs are present. Chronic presentations (pain lasting longer than three months) require a longer rehabilitation period focused on progressive loading rather than passive treatment.

We give you a realistic estimate after the first assessment rather than an open-ended treatment commitment.
