title: PROSPECTIVE STUDY ON TACTILE SENSITIVITY IN THE HANDS OF A BRAZILIAN POPULATION USING THE PRESSURE-SPECIFIED SENSORY DEVICE.
abstract: OBJECTIVE
  To evaluate the pressure perception thresholds on the pulp of two fingers (index and little fingers), among a Brazilian population with no nerve injury or neuropathy.
  
  
  METHODS
  We used the Pressure-Specified Sensory Device (a computerized device) to derive static and dynamic normal pressure perception thresholds and two-point discrimination distances.
  
  
  RESULTS
  We tested finger sensitivity on 30 volunteers. Significance analyses were performed using the Student t test. The mean values (g/mm(2)) for static one and two-point pressure thresholds (s1PD, s2PD) and dynamic one and two-point discrimination (m1PD, m2PD) in the dominant index finger were: s1PD = 0.4, m1PD = 0.4, s2PD = 0.48, m2PD = 0.51.
  
  
  CONCLUSIONS
  There was no significant difference in sensitivity between the dominant and nondominant hands.
