Lumbar spinal stenosis is a condition caused by the narrowing of spaces within the lower spine, which can compress either the spinal cord or nerve roots. This pressure can lead to pain, numbness, or weakness—either locally or radiating down the legs—especially during activities that involve spinal extension (e.g., bending backward or prolonged standing) or compressive loading. While stenosis may result from trauma, congenital anomalies, or systemic diseases, approximately 80% of lumbar spinal stenosis cases are degenerative in origin. Common degenerative contributors include intervertebral disk bulging or herniation, facet joint hypertrophy (arthritis), ligamentum flavum thickening, spondylolisthesis (vertebral slippage), and osteophyte (bone spur) formation. How might chiropractic care help a lumbar spinal stenosis patient both avoid surgical intervention and return to their normal activities to as high a degree as possible?

In the medical model, initial treatment may include physical therapy and/or medications. If those fail to provide relief, a common next step is epidural steroid injections (ESIs), which aim to reduce nerve inflammation and provide temporary symptom relief. A 2025 systematic review of 90 randomized controlled trials found that ESIs can offer short-term improvement in pain and disability but do not result in long-term symptom resolution. If a patient experiences minimal relief after one to two injections, if relief lasts less than one month, or if neurological symptoms progress, further injections are generally not recommended. Clinical guidelines typically limit ESIs to a maximum of three per year, and suggest limiting repeated use to no more than two to three consecutive years due to risks such as bone loss, adrenal suppression, and soft tissue damage.

If the patient pursues chiropractic care, the aim of treatment would be to reduce neural compression by improving lumbar spine mobility and joint spacing. For lumbar spinal stenosis, current guidelines discourage high-velocity, low-amplitude (HVLA) spinal manipulation. Instead, they support gentler techniques such as flexion-distraction, mobilization, and instrument-assisted soft tissue therapies. Chiropractic care may also include targeted exercise, posture training, and neuromuscular re-education to support spinal health and nerve mobility.

Just as critical as in-office treatment is the home management component. Patients are encouraged to perform flexion-based and low-impact exercises—such as stationary biking, inclined treadmill walking, wall sits, and knee-to-chest stretches—which can reduce pressure on lumbar nerves. Core stabilization improves spine support, while posture training and ergonomic adjustments (e.g., lumbar support, avoiding prolonged standing, sleeping with knees elevated) help maintain relief. Lifestyle modifications such as weight loss, an anti-inflammatory diet (rich in omega-3s, vegetables, and whole foods), hydration, and use of ice, heat, or TENS units for pain control can further support long-term improvement.

The good news: with consistent effort, as many as 70% of patients with lumbar spinal stenosis can improve or maintain stable symptoms without ever needing surgery. Only about 30% of patients progress to requiring surgical intervention—typically when pain is disabling, function is severely limited, or neurologic decline occurs.
