People With Low Back Pain Exhibit Higher Trunk Muscle Activity and Impaired Postural Control During Static and Dynamic Functional Tasks: A Cross-Sectional Study.

Low back pain (LBP) is a prevalent musculoskeletal condition affecting millions worldwide. Recent research sheds light on the correlation between LBP and altered trunk muscle activity, leading to impaired postural control during both static and dynamic functional tasks. This cross-sectional study delves into the intricate relationship between LBP and its effects on trunk muscle function and postural stability.

Conducted as a cross-sectional investigation, this study aimed to assess the differences in trunk muscle activity and postural control between individuals with LBP and healthy controls. Participants were subjected to various static and dynamic functional tasks while their trunk muscle activity and postural control were monitored through electromyography (EMG) and motion analysis techniques.

Findings:
The findings revealed notable disparities between individuals with LBP and healthy counterparts. Those experiencing LBP exhibited higher levels of trunk muscle activity across all tasks, suggesting increased muscle tension and compensatory mechanisms. Moreover, individuals with LBP demonstrated impaired postural control, characterized by reduced stability and greater sway during both static and dynamic activities.These findings underscore the significant impact of LBP on trunk muscle function and postural control. Heightened muscle activity and compromised stability may contribute to the perpetuation of LBP and hinder functional performance in daily activities. Understanding these implications is crucial for designing targeted interventions aimed at alleviating LBP symptoms and restoring optimal trunk muscle function and postural stability.As the prevalence of LBP continues to rise, it is imperative to unravel its underlying mechanisms and effects on musculoskeletal function. This cross-sectional study provides valuable insights into the intricate relationship between LBP, trunk muscle activity, and postural control. By elucidating these associations, healthcare professionals can devise tailored treatment strategies to mitigate LBP symptoms and enhance overall musculoskeletal health.

In summary, this study highlights the importance of addressing trunk muscle dysfunction and postural instability in individuals with LBP to promote better outcomes and improved quality of life. Further research is warranted to explore the efficacy of targeted interventions in managing LBP and restoring optimal musculoskeletal function.
