A new method for testing sensibility in the sole of the foot is described. In this method the ability to distinguish different surfaces while walking is assessed. This dynamic, functional and more objective test is recommended as an additional tool to evaluate sensibility in the sole of the foot.
Autologous muscle grafts were used to repair 12 mixed peripheral nerves (9 posterior tibial, 3 median) in 10 patients with leprosy who had total anaesthesia and analgesia of the area supplied by the nerve. Postoperatively, 7 patients reported improved sensation in the foot or hand, with a return of vibration sense and joint position sense in 11 and of perception of a 10 g pin in 5; the ability to sweat in the affected area was also restored in 7.
