Sensory evaluation should be carried out in a systematic manner with the results recorded on an appropriate form that is retained in the patient's case notes. All areas of the foot are tested. The patient should be unable to observe the tester's actions, and lies in a relaxed and comfortable position. Repeat tests should be made and recorded, e.g. every 6-12 months, and where possible retests should be carried out at the same time of day by the same tester.
