福尔斯和跌倒相关的骨折在老年人中很常见，并导致负面的健康结果。肌肉功能和平衡障碍是福尔斯跌倒的重要危险因素。传统的运动可以改善肌肉质量和功能以及平衡。然而，由于身体和认知能力的限制或缺乏坚持，老年人往往不经常锻炼。全身振动有望成为一种运动干预，可以克服传统运动的一些局限性。然而，为了确保安全，在训练时必须保护头部和大脑免受高幅度的加速度。在下肢（踝、膝、髋）没有完全伸展关节角度的情况下保持身体位置会导致更大程度的振动吸收到下肢和下脊柱的软组织中，以及更小程度的传递到上脊柱和大脑。当使用振动锻炼设备时，用户可能不知道他们不正确的身体位置，直到他们开始经历负面副作用。这在有身体和认知障碍的老年人中可能更为明显。在这项工作中，设计了一个系统，使用加速度计来监测用户在不同身体位置的加速度，并使用Microsoft Kinect来记录用户在锻炼时的关节角度。这些设备为用户提供反馈，让他们知道他们是否处于安全的加速度范围内。如果没有，系统将通知他们如何改变他们的姿势以减少加速度的传输。这些信息将有助于打开大门，振动运动的老年人口，帮助他们安全地行使。
Falls and fall-related fractures are common in the elderly and lead to negative health outcomes. Muscle function and balance impairment are important risk factors for falls. Traditional exercise improves muscle mass and function as well as balance. However, older adults often do not exercise regularly because of physical and cognitive limitations or lack of adherence. Whole body vibration promises to be an exercise intervention that can overcome some of the limitations of traditional exercise. Yet to ensure safety, the head and brain must be protected from high amplitudes of acceleration while training. Maintaining a body position without fully extended joint angles in the lower extremity (ankle, knee, hip) leads to a greater degree of vibration absorption into the soft tissues of the lower extremity and lower spine, as well as smaller transfer to the upper spine and brain. When using vibration exercise devices, users can be unaware of their incorrect body position until they begin to experience negative side effects. This is likely to be even more pronounced in older adults with physical and cognitive impairments. In this work, a system is designed using accelerometers to monitor the acceleration of the user at different body locations and a Microsoft Kinect to record the joint angles of the user as they exercise. These devices provide the user with feedback, letting them know if they are in a safe range of acceleration. If not, the system will inform them how to alter their posture to decrease the transmission of acceleration. This information will help open the door to vibration exercise for the geriatric population by aiding them to exercise safely.
