Several muscular degenerative diseases alter motor abilities of large muscles but spare smaller muscles, e.g. keeping hand motor skills relatively unaffected while upper limbs ones are altered. Thus, hand movements could be be used to control an arm exoskeleton for rehabilitation and assistive purpose. Using an infra-red sensors (IR) based interface for the exoskeleton control, this paper descr...

There are numerous causes that can affect the functioning of the human locomotor system, leading to the appearance of joint disorders in the lower limb and generating atypical gait patterns. The importance of research and development in assistance technologies to compensate pathological gait have been recognised since the beginning of the twentieth century and numerous challenges still lie ahea...

The growing number of robotics application fields, mainly in services, has led to the increase of new needs as well as the development of new facilities for teleoperation. Research in the design of more efficient and easy to use human-machine interfaces has propitiated the development of friendly communication systems such as those based on voice or gesture recognition. This work describes a vi...

We developed a powered ankle-foot orthosis that uses artificial pneumatic muscles to produce active plantar flexor torque. The purpose of this study was to quantify the mechanical performance of the orthosis during human walking. Three subjects walked at a range of speeds wearing ankle-foot orthoses with either one or two artificial muscles working in parallel. The orthosis produced similar tot...

stroke is one of the most common diseases among the elderly with high personal and societal costs. in recent years, robotic rehabilitation for stroke has become an active area of research for assistance, monitoring and qualifying the rehabilitation treatments. the key issue needed for improving rehabilitation system is that patient feedback should be taken into account by the robotic rehabilita...

Inspired by the difficulties behind specification requirements as well realizing applicable capacity of upper exoskeleton robots, this paper presents design and development an original prototype Rehabilitation Assistance UPper EXoskeleton (RAUPEX). The is designed through analysis human's limb biomechanics dynamics. Based on human joint power, solutions mechanism actuator for are drawn. During ...

The hybrid assistive limb (HAL) exoskeleton provides rehabilitation of the motor skills of chronic spinal chord injury (SCI) patients as well as alleviation of chronic neuropathic pain (CNP). The HAL device uses bioelectric signals to activate robotic support of voluntary movement during bodyweight supported treadmill training (BWSTT).

Research into rehabilitation robotics has grown rapidly and the number of therapeutic rehabilitation robots has expanded dramatically during the last two decades. Robotic rehabilitation therapy can deliver high-dosage and high-intensity training, making it useful for patients with motor disorders caused by stroke or spinal cord disease. Robotic devices used for motor rehabilitation include end-...

The creation of a human dynamical model useful in upper-limb exoskeleton control remains an open problem. We present a framework that approaches model generation from a “sensor-driven” design perspective that explicitly avoids overfitting parameters and minimally relies on literature values and biological assumptions. Initial results on synthetic data for a simplified model of the elbow indicat...
