As a physiotherapist, I have encountered numerous cases of lumbar spinal stenosis, a condition characterized by the narrowing of the spinal canal in the lower back, leading to nerve compression and resulting in leg pain and weakness. At our clinic we use the McKenzie Method of Mechanical Diagnosis and Therapy, a well-established approach in physiotherapy, to diagnose and treat lumbar spinal stenosis. In this article, I will share my perspective on the diagnosis and treatment of lumbar spinal stenosis using the McKenzie Method, highlighting the significance of mechanical assessment, directional preference exercises, and patient education.
