Innovative Applications of Wearable Waist Exoskeletons in the Medical Rehabilitation Field

Abstract

With the rapid development of exoskeleton technology, especially in the research and application of lumbar-support exoskeletons, key technologies have gradually matured, attracting increasing attention. The lumbar-assisted exoskeleton effectively reduces the burden on the lower back by providing balanced assistive torque at the waist and hips, enhancing efficiency in lifting, heavy handling, and daily work. It has been widely applied in various fields and has become a focus of current exoskeleton technology research. However, currently, the application of waist-assisted exoskeletons in medical rehabilitation scenarios still faces some challenges, mainly in terms of limited functionality and complex wearing procedures. For these issues, a wearable lumbar exoskeleton system that integrates assistance, training, and intelligent protection can be used. By using biomechanical analysis to clarify the spinal structure and movement characteristics, a parallel mechanical structure (S/4-SPS) is employed to achieve multi-degree-of-freedom assisted movement, combined with sensors and control systems to achieve precise assistance and rehabilitation training. In addition, it supports various rehabilitation modes such as gait correction and progressive post-operative training, and can achieve remote health management through cloud data connection, possessing high clinical application value and promotion prospects.
