Spinal Stenosis.
What is spinal stenosis?
Spinal stenosis is a narrowing of the spinal canal — the channel through which the spinal cord and nerve roots travel — that compresses the neural structures and produces characteristic pain and neurological symptoms. It can occur in the cervical, thoracic or lumbar spine, though lumbar stenosis is by far the most common and the primary focus of this page. For cervical stenosis, see our dedicated cervical stenosis page.
Spinal stenosis is typically caused by age-related changes including the development of bone spurs and thickening of ligaments. As the spine degenerates over decades, a combination of factors progressively reduces the available space for the neural structures: facet joint hypertrophy, ligamentum flavum thickening, osteophyte formation, and disc bulging all contribute to narrowing the central canal, the lateral recesses, and the foramina through which nerve roots exit. The result is that neural tissue which previously had ample space is gradually compressed.
Lumbar spinal stenosis is predominantly a condition of older adults, with the highest prevalence in those over 60. It is one of the most common indications for spinal surgery in adults over 65.
Types of lumbar stenosis
The characteristic symptom pattern — neurogenic claudication
Neurogenic claudication is the hallmark presentation of central lumbar stenosis and is one of the most diagnostically distinctive symptom patterns in musculoskeletal practice. The key features are:
Bilateral leg pain, heaviness, aching or numbness that develops with walking or prolonged standing and relieves with sitting or bending forward. Patients characteristically describe needing to stop and sit or lean forward on a shopping trolley to relieve symptoms, then being able to walk again after a few minutes of rest. The forward-leaning position is diagnostically significant — it flexes the lumbar spine, which opens the spinal canal and relieves neural compression.
This pattern distinguishes neurogenic claudication from vascular claudication — where leg pain from arterial insufficiency also develops with walking but is not reliably relieved by sitting versus standing, and is relieved by simply stopping walking regardless of posture. The posture-dependence of neurogenic claudication is pathognomonic.
How is it diagnosed?
Clinical assessment identifies the characteristic symptom pattern, postural influence on symptoms, and neurological signs. MRI is the gold-standard imaging for lumbar stenosis, directly visualising the degree of canal narrowing and neural compression. CT provides useful bony detail for surgical planning. Walking tests — assessing the distance walked before symptom onset — provide a functional measure of severity.
How can physiotherapy help?
Physiotherapy can help manage symptoms, improve function, and enhance quality of life for those with spinal stenosis.
The physiotherapy approach for lumbar stenosis is distinctively flexion-biased — the opposite of the extension-biased approach used for disc herniations. Because lumbar flexion opens the spinal canal and relieves neurogenic claudication, exercises and positions that promote lumbar flexion are the primary therapeutic focus. Aquatic exercise — in a forward-leaning posture — is particularly effective for stenosis as it allows meaningful cardiovascular conditioning and lower limb strengthening in a position that relieves canal pressure.
Core strengthening — specifically targeting the deep stabilisers including multifidus and transversus abdominis — builds the active support system that reduces the dynamic narrowing that occurs when the spine is loaded under poor neuromuscular control. Strengthening the core muscles provides better spinal stability. Hip and gluteal strengthening is equally important — strong hip extensors and abductors reduce the pelvic anterior tilt that narrows the lumbar canal during stance and walking. Real time ultrasound guides deep stabiliser retraining.
Gait training addresses walking abnormalities caused by stenosis. Balance and coordination exercises improve stability and reduce fall risk, which is particularly important for older adults with stenosis. A stationary bike — where the flexed posture relieves canal pressure — is often the most comfortable cardiovascular exercise for stenosis patients and forms a useful foundation for aerobic conditioning during rehabilitation.
Activity modification advice — pacing walking distances, using a walking aid or shopping trolley that encourages forward lean, and identifying the specific positions and activities that provoke and relieve symptoms — empowers patients to maintain active daily function while managing their condition.
For patients with severe stenosis not responding to conservative management, surgical laminectomy or spinal fusion decompresses the neural structures. Physiotherapy plays an important pre-operative preparation role and is central to post-surgical rehabilitation.
Exercise physiology through a Chronic Disease Management Plan is appropriate for patients with co-occurring conditions where broader fitness and weight management are relevant to their stenosis management.

Types of lumbar stenosis
- Central canal stenosis — narrowing of the main spinal canal — compresses the cauda equina (the bundle of nerve roots at the base of the spinal cord) and produces the characteristic bilateral leg symptoms of neurogenic claudication.
- Lateral recess stenosis — narrowing of the bony channel adjacent to the disc and facet joint — compresses individual nerve roots as they exit the central canal, producing unilateral leg symptoms similar to sciatica from disc herniation.
- Foraminal stenosis — narrowing of the opening through which individual nerve roots exit the spine — produces nerve root compression at the level of the foramen, also producing unilateral radicular symptoms.
