To compare test-retest variability of palpation between a new palpometer and manual palpation using (1) right or left hand, (2) index or middle finger, (3) randomized or fixed sequence of force levels, (4) palpation on soft or hard surface, and (5) palpation for 2 or 10 seconds. ⋯ The palpometer had low test-retest variability and provided a more accurate and reproducible pressure stimulus than manual palpation. The findings of this study may help to standardize palpation of human muscles required for accurate and reliable diagnosis of musculoskeletal pain conditions.
