Movement without touch: the life of Ian Waterman
When I first met Ian Waterman in the mid-1980s I could scarcely believe him. He claimed to have lost touch, and movement and position sense (termed proprioception) below the neck, though he could still feel pain and temperature, and his movement nerves were unaffected. Not only was I not aware of any such condition in medicine, but he had walked to the clinic and was sitting calmly as we chatted.
