| Introduction: Low back pain (LBP) is a prevalent musculoskeletal disorder affecting individuals of all ages, including younger populations. A specific subgroup, known as pain developers (PDs), experiences discomfort during prolonged standing despite lacking a prior history of LBP. Core muscle endurance plays a pivotal role in maintaining spinal stability and may help prevent the development of LBP. This study aims to investigate the relationship between core muscle endurance and the onset of pain during prolonged standing in PDs. Methods: Twenty-four female PDs participated in this study. Core muscle endurance was assessed using the McGill test battery, which includes the Sorensen, flexor trunk, and front plank endurance tests. Pain onset was measured in minutes during a two-hour prolonged standing protocol and was defined as the first report of discomfort on the Visual Analog Scale (VAS) with a score greater than 0. Results: A significant positive correlation was found between total McGill endurance time and pain onset (r = 0.46, p = 0.04), suggesting that lower core endurance is associated with earlier pain onset. The Sorensen test (r = 0.44, p = 0.05) and flexor trunk test (r = 0.48, p = 0.02) also exhibited significant positive correlations with pain onset, indicating that endurance of the trunk extensors and flexors is crucial for delaying pain development. However, no significant correlation was found between the front plank test and pain onset (r = 0.31, p = 0.17). Conclusion: Early onset of pain during prolonged standing reflects reduced tolerance to postural load and lower spinal stability. Strengthening core muscles, particularly the trunk extensors and flexors, may enhance spinal stability and delay pain onset, potentially reducing the risk of chronic LBP. These findings underscore the importance of incorporating core endurance exercises into preventive and rehabilitative programs for LBP to improve postural resilience and muscular function. |
