Official title

Immediate Effect Of Standing Trunk Extension Postures On Spinal Height And Clinical Outcome Measures In Low Back Pain: A Randomized Clinical Trial

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Background: Standing trunk extension postures have been used for many years as a mechanical approach to low back pain (LBP), sometimes directed by therapeutic intervention, sometimes subconsciously performed by patientsto relieve LBP. However, no study to date has investigated the effect of standing trunk extension postures on spinal height and clinical outcome measures. Objective: The purpose of this study will be to evaluate in subjects with LBP following a period of trunk loading, how spinal height and/or pain, symptoms' centralization, and function outcome measures respond to:(1) standing repetitive trunk extension posture; and (2) standing sustained trunk extension posture. Lumbar range of motion (ROM) achieved during these two trunk extension postures will be compared to spinal height and outcome measures. Methods:A pre-test, post-test comparison group design (randomized clinical trial) will be used to determine how spinal height changes in response to sustained and repetitive standing trunk extension after a period of spinal loading. The study will evaluate the effects of sustained and repetitive trunk extension in standing on spinal height, pain, symptoms' centralization and function. Statistical Analysis: A mixed ANOVA will be used to statistically identify significant interactions and main effects for spinal height, pain and functionoutcome measures. Post-hoc pairwise comparisons will be used to locate significant differences between the different conditions. Significance will be set at α = 0.05. The Kruskal-Wallis 1-factor ANOVA for difference scores will used to determine changes of intensity and location of symptoms following sustained versus repetitive standing trunk extension. Spearman Rank correlation will be used to evaluate the relationship between spinal height changes and changes of pain and location of symptoms for each group.
