  1. Notes: PAIVMs = central posteroanterior passive accessory intervertebral motion tests; LSI = lumbar segmental instability; CI = 95% confidence interval; LR+ = likelihood ratio for a positive test; LR- = likelihood ratio for a negative test; Accuracy was assessed by lumbar region (upper lumbar and lower lumbar), overall results are presented; Items in bold type are statistically significant at p < 0.05.
