In Peru, about 70% of the population\r\nsuffers from LBP, largely due to heavy physical exertion, forced\r\npostures, and prolonged poor posture, particularly among uni-\r\nversity students who spend long hours sitting. This study aims\r\nto analyze electromyography (EMG) signals of the multifidus\r\nmuscles using the BiTalino device to assess chronic LBP in\r\nuniversity students. Six students (five females and one male) from\r\nUniversidad Peruana Cayetano Heredia (UPCH) participated\r\nvoluntarily. Surface electromyography (SEMG) evaluations were\r\nconducted with electrodes placed at the L3 and L5 vertebrae\r\nlevels. Participants performed movements including standing,\r\nforward flexion, maximum voluntary flexion, and extension. The\r\nSEMG signals were filtered, rectified, smoothed using RMS, and\r\nnormalized for comparison.\r\nThe study also included a survey to explore the relationship\r\nbetween LBP and coffee consumption. The results highlighted\r\nthe Flexion Relaxation Ratio (FRR) FLEX/MVF and EXT/MVF\r\nas effective indices for evaluating chronic LBP. This research\r\nunderscores the importance of posture awareness and early\r\nintervention in managing LBP among university students.","url_abs":"https://github.com/AndreaRazuriMadrid/intro-senales-biomedicas/blob/main/proyecto/Informe%20final%20grupo%207.pdf","url_pdf":"https://github.com/AndreaRazuriMadrid/intro-senales-biomedicas/blob/main/proyecto/Informe%20final%20grupo%207.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"a-cross-sectional-study-to-analyse-the","repo_url":"https://github.com/AndreaRazuriMadrid/intro-senales-biomedicas","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[{"task_slug":"electromyography-emg","task_name":"Electromyography (EMG)"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
