Abstract:
This paper integrates in vivo imaging with finite element modeling to investigate the biomechanical mechanisms underlying acute muscle strain injuries, particularly in the hamstring muscles. Using MRI-based anatomical reconstructions and musculoskeletal modeling, the authors simulate muscle contractions and estimate internal strain distributions during high-risk activities. The analysis reveals specific regions of elevated strain, correlating with common injury locations, and highlights how muscle architecture, activation timing, and joint positioning influence internal load distribution. By combining imaging data with sophisticated mechanical modeling, the study offers novel insights into how biomechanical factors contribute to strain injury susceptibility, thus informing injury prevention strategies and rehabilitation protocols. The work exemplifies how a biomechanics-driven approach can bridge anatomical realism with dynamic mechanical simulation to elucidate soft tissue injury mechanisms.
