In modern medicine, spinal stenosis refers to a condition where the vertebral canal—the passage through which nerves travel within the spine—or the intervertebral foramen, where nerve roots exit, narrows due to various factors, causing nerve compression. Its most common cause is degenerative change brought on by aging. As intervertebral discs wear down and collapse, ligaments around the vertebra thicken through ligamentum flavum hypertrophy, or bone spurs develop via osteophyte formation to press directly on nerves. Spondylolisthesis, in which a vertebra slips out of alignment, can also cause this narrowing.
The primary symptom is neurogenic claudication, where walking a certain distance or standing brings on numbness, aching, bursting leg pain, and weakness that make continued walking difficult. A hallmark of this condition is that symptoms ease when sitting down or bending forward at the waist. This discomfort stems from ischemic pain and local inflammation triggered by poor blood supply from nerve compression. In severe cases, it can lead to hypoesthesia, muscle weakness, or even bowel and bladder dysfunction. Distinguishing this from vascular claudication is crucial, as vascular claudication often fails to resolve immediately upon resting.
While Korean medicine and modern medicine use different terms, their core understandings align. The concept of kidney deficiency in Korean medicine parallels degenerative change in modern medicine: a declining ability to regenerate and maintain bones, cartilage, and ligaments with age reflects weakened kidney function. Likewise, a qi and blood circulation disorder corresponds to the inflammatory response and reduced blood flow caused by nerve compression. Compressed nerves develop local edema and accumulate inflammatory substances, which obstruct the movement of qi and blood and amplify pain.
Modern medicine pinpoints the exact site of nerve compression using magnetic resonance imaging and computed tomography, managing symptoms with analgesic anti-inflammatory drugs, nerve injections, physical therapy, or surgery when necessary. Korean medicine uses acupuncture, moxibustion, cupping, and herbal medicine to ease inflammation and edema around the narrowed vertebral canal while promoting blood circulation to restore nutrient delivery to the nerves. In addition, herbal formulas that replenish weakened kidney function help fortify the tissues surrounding the spine, slow degenerative progression, and support the back's inherent ability to heal and bear weight. Combining Western and Korean medical care can produce meaningful synergy, offering a holistic path to both pain relief and improved quality of life.
