| Popis: | Background Evidence on the diagnostic performance of palpatory methods and possible confounding factors is scarce. Objectives To examine the sensitivity of palpatory methods for location of lumbopelvic landmarks and to assess its association with personal characteristics. Methods Eighty-three participants (41 men, 55.6 (16.5) years, 25.9 (4.8) kg/m2 [mean (SD)]) were enrolled in this single-blinded study. Fourteen body and softy-tissue landmarks were sequentially palpated from the spinous process of L4 to the ischial tuberosity. CT-scan images were used to assess what landmark was located. Results Sensitivity for location was in range 22-86% for soft-tissues and 26-69% for bony landmarks. Reduction in sensitivity was observed from the quadratus lumborum to the inferior and lateral angle of the sacrum (86-26% and 75-33%, left and right sides, respectively). Palpations of L4 and L5 spinous processes were systematically more cephalic than other landmarks. Gender was weakly correlated to almost all landmarks (rpb= 0.333 or weaker). Body mass index was weakly correlated to the accurate location of ILAS and quadratus lumborum, great trochanter, PSIS, and piriformis (rpb=-0.307 or weaker). Conclusions Systematic and propagation errors were present using sequential palpatory methods. Palpation in men was more sensitive and higher BMI was associated with lower sensitivity for lumbopelvic landmarks. |
