Background: The evaluation of causes and consequences of non-specific low back pain along with related symptoms are critical in terms of planning the treatments of patients. Muscular imbalance can cause postural impairment and reduced functional performance in individuals with low back pain. Therefore, determining the role of trunk muscular endurance in individuals with non-specific low back pain and its reflections on dynamic postural control and functional performance are very important for both patients and physiotherapists in terms of establishing an effective treatment program.

Methodology: 39 participants with non-specific LBP aged between 18-50 years were included in this study. Biering–Sorensen test, Y-balance test and 5 min walk test were the outcome measures used to evaluate trunk extensor endurance, dynamic postural control and functional performance.

Result: Using Karl Pearson’s Correlation coefficient, strong positive correlation was observed between trunk extensor endurance and 5-minute walk test, and between trunk extensor endurance and Y-balance test, which was found to be highly statistically significant.

Conclusion: This study concludes that there is a strong positive correlation exist between trunk extensor endurance and dynamic postural control, and also between trunk extensor endurance and functional performance in patients with non-specific low back pain.
