Fig 1 Movement detection thresholds in (A) traumatic and (B) vascular amputees at the nonamputated knee and ankle levels. Thresholds (in degrees) correspond to the minimal amplitude of the angular displacement able to elicit a movement sensation. Touch-pressure perception thresholds in (C) traumatic and (D) vascular amputees at the nonamputated tibial and plantar sites. The thresholds, expressed in log of 10 times the force (in milligrams) applied to the skin, were determined using Semmes-Weinstein filaments by the method of limits. Means +1 standard error of the mean are shown. *P<.05; †P<.001; ‡P<.01.
