Control Scheme

Most control methods deployed in lower extremity rehabilitation robots cannot automatically adjust to different gait cycle stages and different rehabilitation training modes for different impairment subjects. This article presents a continuous seamless assist-as-needed control method based on sliding mode adaptive control. A forgetting factor is introduced, and a small trajectory deviation from reference normal gait trajectory is used to learn the rehabilitation level of a human subject in real time. The assistance torque needed to complete the reference normal gait trajectory is learned through radial basis function neural networks, so that the rehabilitation robot can adaptively provide the assistance torque according to subject’s needs. The performance and efficiency of this adaptive seamless assist-as-needed control scheme are tested and validated by 12 volunteers on a rehabilitation robot prototype. The results show that the proposed control scheme could adaptively reduce the robotic assistance according to subject’s rehabilitation level, and the robotic assistance torque depends on the forgetting factor and the active participation level of subjects.

In a state-of-the-art paper on skiing performance and on skiing safety, aspects of ski boot design are discussed. The influence of ski boots on the skier-bootbinding-ski system is described, and suggestions are made about improving ski boots regarding better skiing performance, less inadvertent binding releases, and less lower extremity equipment related injuries. The design of the boot sole and the boot shaft with its influence on binding release values is particularly described. Furthermore, in the forward lean the shaft stiffness of modern ski boots and their pressure distribution is very important for good skiing performance and reduction of injuries of the ankle joint and the tibia. The built-in forward lean and the stiffness to the rear can be related to the acting forces in the anterior cruciate ligament, and first approximations to reduce the risk of these injuries are given.

Active Assistance

Stroke represents the main cause of disability in adults. The disability is caused by motor or sensitive impairment, loss of interjoint coordination, spasticity and pathological synergies that occur after stroke. The new directions in motor rehabilitation point at facilitating neuroplasticity by multimodal stimulation, like virtual reality, or by active assistance in task specific training, like rehabilitation robots associated or not with functional electrical stimulation (FES). The aim of this article is, on one hand, to analyze the way in which the existing robots face the biomechanical challenges of modeling the upper limb`s movements and, on the other hand, to evaluate the efficiency of robotics in rehabilitation, by pointing out the results of the existing clinical trials. Finally, possible directions for future research are discussed.
