Vasomotor function in the lower limbs was tested by means of thermography in 48 patients with and without residual complaints after surgery for a prolapsed intervertebral disc. There is a definite correlation between the severity of the complaints and the thermographic responses which corresponds well with the evidence for a sympathetic reflex dystrophy of the legs (causalgia).
