Neurogenic claudication (NC), also known as pseudoclaudication, is the most common symptom of lumbar spinal stenosis (LSS) and describes intermittent leg pain from impingement of the nerves emanating from the spinal cord. [1] [2] Neurogenic means that the problem originates within the nervous system.
Intermittent neurogenic claudication [17] [20] [21] characterized by lower limb numbness, weakness, diffuse or radicular leg pain associated with paresthesia (bilaterally), [20] weakness and/or heaviness in buttocks radiating into lower extremities with walking or prolonged standing. [17]
Vascular claudication can resemble spinal stenosis, and some individuals experience unilateral or bilateral symptoms radiating down the legs rather than true claudication. [7] The first symptoms of stenosis include bouts of low back pain. After a few months or years, this may progress to claudication.
Spinal or neurogenic claudication may be differentiated from arterial claudication based on activity and position. In neurogenic claudication, positional changes lead to increased stenosis (narrowing) of the spinal canal and compression of nerve roots and resultant lower extremity symptoms. Standing and extension of the spine narrows the spinal ...

Intermittent claudication, also known as vascular claudication, is a symptom that describes muscle pain on mild exertion (ache, cramp, numbness or sense of fatigue), [1] classically in the calf muscle, which occurs during exercise, such as walking, and is relieved by a short period of rest.
Tarlov cysts are most commonly located in the S1 to S4/S5 region of the spinal canal, but can be found along any region of the spine.They usually form on the extradural components of sacrococcygeal nerve roots at the junction of dorsal root ganglion and posterior nerve roots and arise between the endoneurium and perineurium. [10]
Narrowing of the lumbar spinal canal causes a clinical condition known as neurogenic claudication, characterized by symptoms such as lower back pain, leg pain, leg numbness, and leg weakness that worsens with standing and walking and improves with sitting and lying down. [6]
