Challenges in Kinetic-Kinematic Driven Musculoskeletal Subject-Specific Infant Modeling

Abstract: Musculoskeletal computational models provide a non-invasive approach to investigate human movement biomechanics. These models could be particularly useful for pediatric applications where in vivo and in vitro biomechanical parameters are difficult or impossible to examine using physical experiments alone. The objective was to develop a novel musculoskeletal subject-specific infant model to investigate hip joint biomechanics during cyclic leg movements. Experimental motion-capture marker data of a supine-lying … Show more

“…Motion capture technology was used to capture the spontaneous kicking without any external stimulation. A kick was defined as significant movement at the hip joint, exhibiting extension, maximum flexion, and extension again, and was isolated over 3 seconds for each hip 18 . The infant was allowed to move freely and naturally during data collection.…”

“…There are applications in injury prevention [2][3][4] , in vivo health monitoring 5 , clinical outcomes [6][7][8][9][10][11] , and occupational ergonomics [12][13][14] , but most research is focused on the adult population. Few studies have studied human movement in pediatric populations [15][16][17] , and even fewer have studied infants under one year old 18 . The current methods to develop pediatric musculoskeletal models include scaling generic adult models or using medical imaging data (CT or MRI scans) to develop subject-specific models.…”

“…For this study, an infant musculoskeletal model was coupled with a robotic system. Infant knee kinematics, obtained from a previously developed musculoskeletal model [5], were used as an input to drive a knee exoskeleton and to assess the accuracy of the exoskeleton's output. The general workflow for the proposed framework is shown in Figure 1.…”
