Abstract

TUSTUMI, Francisco et al. Prospective study on tactile sensitivity in the hands of a brazilian population using the pressure-specified sensory device. Rev. bras. ortop. [online]. 2012, vol.47, n.3, pp.344-347. ISSN 0102-3616.  http://dx.doi.org/10.1590/S0102-36162012000300011.

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/mm2) 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. CONCLUSION: There was no significant difference in sensitivity between the dominant and nondominant hands.
