“…Some previous studies investigated the influences of the muscle foreces on head neck injuries, but they generally adopted assumed or PID-based muscle activations [11,13,15]. To our knowledge, no study reported the effects of realistic human neural reflex on head-neck impact responses during impact environments.…”

“…An angle-based and length-based active muscle controller was implemented in the ViVA OpenHBM [12]. Pre-activation with the OpenSim computed muscle control method and PID-based control strategies were included in the Human Active Lower Limb (HALL) model for lower limbs [14,15]. Some MB models with muscle control strategies were also developed for investigating active muscle effects during sportive or impact injuries, etc., from 1-pivot models [16][17][18][19] to detailed subsegments [20][21][22][23][24][25].…”

Objective: Neck muscle activation plays an important role in maintaining posture and preventing trauma injuries of the head-neck system, levels of which are primarily controlled by the neural system. Thus, the present study aims to establish and validate a neuromuscular headneck model as well as to investigate the effects of realistic neural reflex control on head-neck behaviors during impact loading. Methods: The neuromuscular head-neck model was first established based on a musculoskeletal model by including neural reflex control of the vestibular system and proprioceptors. Then, a series of human posture control experiments was implemented and used to validate the model concerning both joint kinematics of the cervical spine and neck muscle activations. Finally, frontal impact experiments of varying loading severities were simulated with the newly established model and compared with an original model to investigate the influences of the implanted neural reflex controllers on head-neck kinematic responses. Results: The simulation results using the present neuromuscular model showed good correlations with in-vivo experimental data while the original model even cannot reach a correct balance status. Furthermore, the vestibular reflex is noted to dominate the muscle activation in less severe impact loadings while both vestibular and proprioceptive controllers have a lot of effect in higher impact loading severity cases. Conclusions: In summary, a novel neuromuscular head-model was established and its application demonstrated the significance of the neural reflex control in predicting in vivo head-neck responses and preventing related injury risk due to impact loading.

“…Even in the stretched muscle, the deformation of the muscle is relatively small, in which scenario, the mechanical role of muscle fibers is considered to be trivial and will not significantly influence the conclusions made in the present study. Nevertheless, to enable the simulation of more complex loading scenarios, the muscle fibers should be simulated using some advanced modeling techniques 44,45 and then the mechanical role of muscle fibers should be properly investigated in the future studies. Secondly, the impairment of the muscular tissues is simulated by changing the mechanical properties of the muscular tissues.…”

The beneficial effects of the medical compression stocking (MCS) in the treatment of venous disorders of the human lower limb have been recognized. However, the effectiveness of the MCS on the internal tissues of the lower limb has not been properly evaluated. The aim of the present study was to shed light on the mechanism of compression therapy using a highly anatomical fidelity three-dimensional finite element (FE) model. A FE calf model of a 40-year-old female was created from magnetic resonance images, in which the bones, the muscle groups, three veins (the great saphenous vein, medial peroneal vein and small saphenous vein), the subcutaneous tissues (fascia) and the skin were reconstructed. The model was validated using experimental data collected in-house, and then the influence of different levels of external compression and the biomechanical effect of the MCS under the pathological conditions were investigated. The results showed that the pressure at the skin–stocking interface was largely influenced by the external compression pressure with an increase of up to 54.98%, while the pressure was neither influenced by the impairment of the muscular tissues nor by the impairment of the calf veins, with the largest change of just 5.63%. The trans-mural pressure was increased more by the impairment of the calf veins than by the impairment of the muscular tissues. The volume reductions in the calf veins were not evenly distributed. The present study provides some guidance on compression therapy.

“…Our recent study indicates that combining musculoskeletal model method for pre-defined muscle activation can be a good choice for defining muscle activation in FE human-body model. 25 In this case, more complicated human movement during driving can be simulated and studied. In addition, this study adopts one specific car model and three typical impact conditions.…”

Accident data shows that driver’s kinematics response in real accidents can be significantly different from that in dummy or cadaver tests because of driver’s muscle contraction. In this study, a finite element human-body model consisting of an upper body of a dummy model and a lower limb–pelvis biomechanical model with three-dimensional active muscles was developed to investigate in depth the lower-limb injuries. Driver’s emergency reaction during frontal impact was simulated by modelling muscle active contraction based on a series of volunteer experimental tests. Besides, a realistic impact environment with the response of the restraint system and the invasion of the driver’s compartment was established in this study. The results show that muscle contraction can cause extra loads on lower limbs during the impact, which can increase the injury risk of lower limbs. As for the femur injury, muscle contraction caused an additional 1 kN axial load on the femur, and the femur resultant bending moment of active models was also higher by about 10–40 N m. Besides, the tibial index of the model with muscle activation was about 0.1 higher. In addition, the results indicate that the femur injury is strongly related to the combined action of both axial force and bending moment. The variation of the injury tolerance along the tibia shaft should be considered when evaluating the tibia injury. Overall, the current lower-limb injury criteria can be still the lack of robustness.
