Degenerative Disc Disease.
What is degenerative disc disease?
Degenerative disc disease (DDD) is a term used to describe age-related changes in the intervertebral discs — the cushioning structures between each vertebra. As we age, discs gradually lose hydration, becoming thinner, less flexible and less effective at absorbing load. The disc's outer ring (annulus fibrosus) develops small tears, and the disc height reduces as the nucleus pulposus dehydrates. On imaging, these changes are visible as disc space narrowing, reduced disc signal on MRI, and sometimes osteophyte (bone spur) formation at the vertebral endplates.
It is worth addressing a common and important misconception upfront: degenerative disc disease sounds alarming, but it is neither a disease in the conventional sense nor a reliable predictor of pain. These changes are a normal part of spinal ageing — studies show that by age 40, approximately 90% of people have some degree of disc degeneration visible on MRI, and the majority have no symptoms at all. The correlation between the degree of disc degeneration on imaging and the severity of pain is genuinely weak. Many people with severe degeneration on MRI have no back pain, and many people with significant pain have minimal imaging changes.
This does not mean the diagnosis is meaningless — disc degeneration is a genuine structural change that can contribute to pain through several mechanisms — but it does mean that receiving a DDD diagnosis on an MRI report is not a sentence to chronic pain, and that the appropriate response is active management rather than fear and avoidance of movement.
How does DDD cause pain?
When disc degeneration does contribute to symptoms, it does so through several mechanisms. Discogenic pain — pain arising from the disc itself, particularly from the nociceptors in the outer annular fibres — produces central lower back or neck pain that is typically worse with sustained loading, prolonged sitting, and bending under load. Disc degeneration also predisposes to disc herniation, as the degenerating annulus is more vulnerable to tearing under mechanical load. Reduced disc height increases the load on the facet joints at the back of the spine, contributing to facet arthropathy. Progressive disc degeneration can narrow the foramina through which nerve roots exit, contributing to radiculopathy.
DDD occurs in both the lumbar and cervical spine, with L4-5 and L5-S1 the most commonly affected lumbar levels and C5-6 and C6-7 the most commonly affected cervical levels.
What are the symptoms?
Symptoms of lumbar DDD typically include central or unilateral lower back pain that is worse with prolonged sitting, bending and loading, and relieved by lying down and changing position. Morning stiffness is common. Pain may refer into the buttocks and thighs but typically does not extend below the knee unless nerve root compression is also present. Cervical DDD produces neck pain, stiffness, and headaches, and may contribute to arm symptoms if associated nerve root involvement is present.
How is it diagnosed?
DDD is identified on MRI or CT scan, though as noted above, imaging findings must always be interpreted in clinical context. A physiotherapy assessment evaluates the functional implications of the disc changes — which positions and movements provoke and relieve symptoms, what the neurological status is, and which structures are most likely contributing to the patient's specific presentation.
How can physiotherapy help?
Physiotherapy can play a significant role in helping individuals with degenerative disc disease manage their symptoms, improve their quality of life, and potentially delay the progression of the condition.
Education is one of the most important physiotherapy interventions for DDD — helping patients understand that their imaging findings are common, that degeneration does not reliably predict pain, and that activity and exercise are protective rather than harmful. The fear-avoidance behaviour that develops when people believe their spine is damaged and fragile is one of the most consistent drivers of chronic pain in DDD, and addressing this directly produces meaningful clinical benefit.
Deep core muscle retraining — specifically the multifidus and transversus abdominis — is central to the exercise management of lumbar DDD. These muscles are consistently found to be inhibited and atrophied in people with chronic disc-related back pain, and their rehabilitation significantly reduces pain and recurrence. Real time ultrasound guides this retraining by providing direct visualisation of the deep muscles.
Strengthening exercises target the muscles that support the spine, helping to stabilise the affected area and reduce stress on the degenerated discs. Flexibility and range of motion exercises improve spinal function and reduce stiffness. Core strengthening provides better support to distribute load more evenly across the spine.
Hip and gluteal strengthening is equally important — the gluteal muscles are the primary load-sharing partners of the lumbar spine, and their strengthening reduces the compressive demands placed on the degenerated discs during daily activities.
Posture and body mechanics education teaches patients how to sit, stand, lift, and perform daily activities without putting excessive strain on the spine. Manual therapy reduces pain and improves mobility in the surrounding spinal segments. Dry needling assists with pain management in the paraspinal and gluteal musculature.
Clinical Pilates is particularly well suited to DDD management — the emphasis on deep core activation, spinal alignment and progressive functional loading provides a structured and sustainable exercise environment that can be maintained long-term. For patients with co-occurring conditions including obesity, diabetes or cardiovascular disease, exercise physiology through a Chronic Disease Management Plan addresses these alongside the disc condition.
For patients whose DDD has progressed to the point where discectomy, spinal fusion or artificial disc replacement is being considered, structured prehabilitation before surgery and post-surgical rehabilitation are both important components of care. For patients whose condition arose from a workplace or motor vehicle injury, WorkCover and CTP funded physiotherapy is available.
