Validation of cutaneous pressure threshold measurements for the evaluation of hand function.
The relationship of measures of pressure perception to hand function was evaluated by correlating the results of the Mayo Dexterity Test and a timed object recognition test with the one- and two-point static and moving touch thresholds for the index finger pulp of 44 hands. The Mayo Dexterity Test permits the use of vision, while the object recognition test does not. Quantitative sensory testing was done with the Pressure-specifying Sensory Device. Cutaneous pressure threshold measurements with this device had a statistically significant correlation with the small-object subset of the Mayo Dexterity Test (p < 0.006) and with the object recognition test (p < 0.001), demonstrating that the Pressure-specifying Sensory Device is a valid tool for evaluating the sensory aspect of hand function.
