Responsiveness of the bridge maneuvers in subjects with symptomatic lumbar spondylolisthesis: A prospective cohort study

The objective of this study is to examine the responsiveness of the BTs in subjects with symptomatic lumbar SPL. MethodsOne hundred twenty patients with symptomatic SPL received physical therapy treatments for a number of sessions depending on the individual patient's needs. Each session included supervised exercises and the teaching of home exercises aiming to improve the lumbar stability, for about 1 hr in total. At the beginning and immediately after the last session of treatment, participants completed the Oswestry Disability Index – Italian version and the Pain Numerical Rating Scale, and performed the supine bridging (SBT) and the prone bridging (PBT). The global perception of effectiveness was measured with a seven‐point Likert scale Global Perceived Effect questionnaire. ResultsThe mean post‐treatment change score (95% confidence interval [CI]) was 18.2 s (14.5; 21.9) for the PBT and 43.9 s (35.1; 52.8) for the SBT, all p < .001. The area under the receiver operating characteristic curve for the PBT was 0.83 (95% CI 0.74–0.91) and for the SBT was 0.703 (95% CI 0.61–0.80). The optimal cutoff points were 19.5 s for the PBT and 62.5 s for the SBT. Logistic regression revealed that PBT (odds ratio = 0.952) was associated with the type of SPL. The final regression model explained 36.4% (R2 = 0.36; p = .001) of the variability. DiscussionBridge maneuvers proved to be responsive, because their results were significantly related to pain and disabilit...
