A cross-sectional study to analyse the presence of low back pain in university students and its relationship with coffee

Low back pain (LBP) is a prevalent condition affect- ing a significant portion of the global population and a leading cause of physical disability. In Peru, about 70% of the population suffers from LBP, largely due to heavy physical exertion, forced postures, and prolonged poor posture, particularly among uni- versity students who spend long hours sitting. This study aims to analyze electromyography (EMG) signals of the multifidus muscles using the BiTalino device to assess chronic LBP in university students. Six students (five females and one male) from Universidad Peruana Cayetano Heredia (UPCH) participated voluntarily. Surface electromyography (SEMG) evaluations were conducted with electrodes placed at the L3 and L5 vertebrae levels. Participants performed movements including standing, forward flexion, maximum voluntary flexion, and extension. The SEMG signals were filtered, rectified, smoothed using RMS, and normalized for comparison. The study also included a survey to explore the relationship between LBP and coffee consumption. The results highlighted the Flexion Relaxation Ratio (FRR) FLEX/MVF and EXT/MVF as effective indices for evaluating chronic LBP. This research underscores the importance of posture awareness and early intervention in managing LBP among university students.
