Establishment of reliability in the evaluation of hand sensibility.
Evaluation of hand sensibility using measures of threshold and tactile discrimination are standard assessment methods following nerve injury. Many of the available sensory measures for the quantification of hand sensibility lack verification of intertester reliability. Intertester reliability of vibration threshold, cutaneous pressure threshold, two-point discrimination, object identification, and texture identification was established. The intraclass correlation coefficient ranged from 0.96 to 0.99 for all variables except texture identification (r = 0.77). Comparisons were made between the sensory measures and each functional measure. The strongest correlational relationship was between two-point identification and object identification. Based on the results of this study, evaluation of hand sensibility may be attained with measurement of vibration and cutaneous pressure threshold, two-point discrimination, and object identification.
