Special Issue Information

Dear Colleagues,

The human body sustains a wide range of forces and impacts from external and internal environments throughout life. These loadings can act on the body via different contacts or fields. Some of the loadings are necessary for the physiological and mechanical performance of the human body, while some of the loadings may harm the human body by violent injuries or accumulated damages.

The biomechanics of injuries or trauma is a scientific area that uses mechanical principles to explain injury and trauma rationales, predict risk factors, explore the tolerance level and response of human tissues to specific loading conditions, and provide scientific fundamentals for the ergonomic design of body protection and body supports. A sufficient exploration of the biomechanics of injury and trauma is thus efficient and necessary for the alleviation, elimination, or precaution of injuries and traumas, even for injury treatments and rehabilitation. It covers a wide range of areas, such as basic anatomy, tissue properties, tissue reaction, human motion, loading pattern, injury classification and mechanism, body support, ergonomic designs, engineering, computational analysis, etc., from micro- to macro-level science and technologies, and from the intrinsic to the extrinsic environment of the human body. It is not only a way that explores the way the body responds to various forces, but also a way to understand the physiological and mechanical performance of the human body as adaption strategies to all the sustained loading conditions.

This Special Issue on the biomechanics of injury and trauma aims to collect cutting-edge technologies, innovations, and research findings in research and development industries in the field of injury biomechanics, for the purpose of promoting applications of advances for injury precaution, as well as stimulating new creations for injury management.

Background: Iliotibial band syndrome (ITBS) is one of the most prevalent overuse injuries in runners. The strain rate in the iliotibial band (ITB) has been theorized to be the primary causative factor in the development of ITBS. Running speed and exhaustion might lead to an alteration in the biomechanics that influence the strain rate in the iliotibial band. Objectives: To identify how exhaustion states and running speeds affect the ITB strain and strain rate. Methods: A total of 26 healthy runners (including 16 males and 10 females) ran at a normal preferred speed and a fast speed. Then, participants performed a 30 min exhaustive treadmill run at a self-selected speed. Afterward, participants were required to run at similar speeds to those of the pre-exhaustion state. Results: Both the exhaustion and running speeds were revealed to have significant influences on the ITB strain rate. After exhaustion, an increase of approximately 3% in the ITB strain rate was observed for both the normal speed (p = 0.001) and the fast speed (p = 0.008). Additionally, a rapid increase in the running speed could lead to an increase in the ITB strain rate for both the pre- (9.71%, p = 0.000) and post-exhaustion (9.87%, p = 0.000) states. Conclusions: It should be noted that an exhaustion state could lead to an increase in the ITB strain rate. In addition, a rapid increase in running speed might cause a higher ITB strain rate, which is proposed to be the primary cause of ITBS. The risk of injury should also be considered due to the rapid increase in the training load involved. Running at a normal speed in a non-exhaustive state might be beneficial for the prevention and treatment of ITBS. Full article

Traumatic brain injury (TBI) is a prevalent injury among cyclists experiencing head collisions. In legal cases, reliable brain injury evaluation can be difficult and controversial as mild injuries cannot be diagnosed with conventional brain imaging methods. In such cases, accident reconstruction may be used to predict the risk of TBI. However, lack of collision details can render accident reconstruction nearly impossible. Here, we introduce a reconstruction method to evaluate the brain injury in a bicycle–vehicle collision using the crash helmet alone. Following a thorough inspection of the cyclist’s helmet, we identified a severe impact, a moderate impact and several scrapes, which helped us to determine the impact conditions. We used our helmet test rig and intact helmets identical to the cyclist’s helmet to replicate the damage seen on the cyclist’s helmet involved in the real-world collision. We performed both linear and oblique impacts, measured the translational and rotational kinematics of the head and predicted the strain and the strain rate across the brain using a computational head model. Our results proved the hypothesis that the cyclist sustained a severe impact followed by a moderate impact on the road surface. The estimated head accelerations and velocity (167 g, 40.7 rad/s and 13.2 krad/s2) and the brain strain and strain rate (0.541 and 415/s) confirmed that the severe impact was large enough to produce mild to moderate TBI. The method introduced in this study can guide future accident reconstructions, allowing for the evaluation of TBI using the crash helmet only. Full article
