OBJECTIVES: This study investigated the inter-rater reliability of three
structural end range lumbar segmental instability tests with the highest positive
likelihood ratio (+?LR) against flexion-extension radiographs, and three
functional mid-range clinical tests that predict the success of lumbar
stabilisation exercises in patients with recurrent or chronic low-back pain
(R/CLBP). The study also investigated the reliability of lumbar segmental
instability, subclassification as: functional, structural and combined
instability. METHOD: Forty adults with R/CLBP (30 men and 10 women), aged
21-71?years, underwent repeated measurements of specific clinical tests for
structural or functional lumbar segmental instability. RESULTS: All
functional-instability tests: the prone instability test (PIT), the aberrant
motion test and the average passive straight-leg raise (PSLR>91°) test showed a
high percentage agreement (90, 97·5 and 95%, respectively) and a high kappa
coefficient (0·71, 0·79 and 0·77, respectively). In addition, two structural
tests: the lumbar flexion range of motion (ROM) >53° and the passive lumbar
extension test (PLET) showed a high percentage agreement (82 and 73%,
respectively), and a moderate kappa coefficient (0·48 and 0·46, respectively).
The lack of hypomobility with the posteroanterior (PA) glide test was found to be
unreliable (agreement?=?25%; k?=?-?0·02). Locating the pain-provoking segment, as
the first portion of PIT, was found to be moderately reliable (k?=?0·41). The
subclassification categories of lumbar segmental instability (functional,
structural and combined) were found to be significantly reliable (PABAK) 0·90,
0·70 and 0·95, respectively). DISCUSSION: All investigated tests (except the lack
of hypomobility with the PA glide test), in addition to subclassifying the
categories of lumbar segmental instability, were significantly reliable in the
assessment of lumbar instability.
