The symptoms of Lumbar Canal Stenosis are cauda equina claudication, unremitting back pain and sciatica. Cauda equina claudication is chiefly chracterized by weakness and numbness in the leg.
In evaluating its synptoms, we used Thermography for 24 cases of Lumbar Canal Stenosis.
In 2/3 cases, thermogram showed the area of the numbness of the leg nearly. On cooling and venous occluding test, the temperature of the leg became smoothly low down.
After removing the load, the surface temperature recovered according to the severity of the symptoms.
