The aims of this study were to compare test-retest variability and accuracy measures between (1) manual palpation and a novel palpometer and (2) different force levels. Sixteen clinicians were instructed to target 0.5, 1.0, and 2.0 kg on a force meter using manual palpation and the new palpometer (adjustable spring-coil with a small pin touching the examiner's hand when the correct pressure is reached). In all experiments, 10 consecutive measures of the force levels were recorded. ⋯ All outcome parameters had significantly lower values for the new palpometer than for manual palpation in a force-dependent manner (p<0.004). CVs and actual force levels were significantly different between all target levels (p<0.004). The new palpometer had low test-retest variability and provides a more accurate pressure stimulus than manual palpation.
