Gait Assessment in Lumbar Spinal Stenosis

Lumbar spinal stenosis (LSS) is a clinical condition in which the structures within the canal are compressed as a result of the narrowing of the lumbar spinal canal and nerve root canals, which is often caused by bones and soft tissues, causing back pain and neurological deficits in the lower extremities. The incidence in the general population has been reported as 1.7-8%. It begins to be seen after the age of 50 and its incidence increases after the age of 65. According to studies, LSS has been detected in 5% of patients who apply to a general practitioner with persistent back pain. Although it can be congenital, most cases of lumbar spinal stenosis are caused by changes in the aging spine as a result of degenerative processes. Changes that can lead to lumbar spinal stenosis include facet joint hypertrophy, decreased intervertebral disc height, osteophyte formation and ligamentum flavum hypertrophy. Clinical findings of LSS include symptoms such as back pain, leg pain, paresthesia, weakness and neurogenic claudication. Patients with neurogenic claudication experience increased pain when walking and standing and decreased pain when bending forward. Patients with LSS often change their spinal posture to allow more lumbar flexion to minimize pain and symptoms while walking; this can lead to gait abnormalities. Walking function is important for the maintenance of daily living activities. Gait disturbance is associated with poor health outcomes. In a gait cycle, the foot has two…
