Abstract

Introduction: Chronic low back pain (CLBP) presents neuromuscular dysfunctions, per example, the reduction of muscle strength and endurance. They are essential in performing tasks and postural maintenance. Objective: This study was to characterize the muscle strength and endurance. It checked the discriminant variables to CLBP population. Methods: 35 sedentary young females aged 18 to 27 years old. They were assessed and divided in with CLBP (n=18) and a without LBP (n=17). The assessment included the measurement of pain level (Visual Analogue Scale), isometric strength of trunk extensor muscles (Lumbar Dynamometer) and static endurance of trunk extensors muscles (Biering-Sorensen Test). A Multivariate Analysis of Variance and a Discriminant Analysis were performed adopting a 5% level of relevance. Results: The group with CLBP presented decrease muscle strength (21%; p=0.01) and endurance (71%, p<0,001). The discriminant analysis should diagnostic accuracy to endurance 97.1% and strength 68.7%. Conclusion: Strength and endurance of extensors of trunk extensor muscles discriminant LBPC.
