A Novel Approach for Investigation on Lateral Fall Injuries and Mitigation Strategies using Electromyography (EMG) and Bayesian Optimization

人类跌倒的问题，特别是在老年人中，可能会导致严重的伤害，如软组织损伤或骨折，甚至导致死亡，取决于事故的严重程度。本研究的目的是找出可能对跌倒伤害的严重程度产生重大影响的因素，以及这些因素如何影响跌伤的严重程度。在我们进行的一项调查中，我们调查了软组织僵硬，软组织僵硬可能在确定跌倒或任何碰撞(如跌倒期间的人机碰撞或跌倒或碰撞期间的不同冲击速度)过程中所受伤害的程度方面发挥重要作用。在横向跌倒或向前跌倒的第二次撞击中，上臂极有可能受损。在一项以受试者为基础的实验中，使用钟摆测量了上臂的软组织硬度。软组织的变形和冲击可以使用力传感器和超声波技术来测量。作为这项研究的结果，我们能够证明不同的冲击速度会导致非线性软组织的刚度行为发生不同的变化。此外，我们使用了各种压痕冲击器来获得冲击器冲击过程中软组织的僵硬行为。

The problem of human falls, particularly among the elderly, is one that can result in serious injuries, such as a soft tissue injury or a bone fracture, or even result in death depending on the severity of the accident.The purpose of this study's goal was to find out the factors that may have a significant impact on the severity of fall injury as a result of a fall, and how these factors may influence the severity of the fall injury. In an investigation that we conducted, we investigated soft tissue stiffness that may play a significant role in determining the extent of injury sustained during a fall or any collision such as machine-human impact during a fall or collision for a variety of impact velocities during a fall or collision.It is highly likely that the upper arm will be damaged during a lateral fall or a second impact during a forward fall. Soft tissue stiffness in the upper arm was measured using a pendulum during a subject-based experiment. Soft tissue deformation and impacts can be measured using force sensors and ultrasonic technology.As a result of this study, we were able to demonstrate that different impact velocities result in different changes in the stiffness behavior of nonlinear soft tissues. In addition, we used a variety of indentation impactors to obtain the behavior of the stiffness of soft tissues during the impact of the impactor.
