Many of the current implementations of exoskeletons for the lower extremities are conceived to either augment the user's load-carrying capabilities or reduce muscle activation during walking. Comparatively little research has been conducted on enabling an exoskeleton to increase the agility of lower-limb movements. One obstacle in this regard is the inertia of the exoskeleton's mechanism, which...

This article presents a wearable lower extremity exoskeleton (LEE) designed to augment the ability of a human to walk while carrying payloads. The ultimate goal of the current research is to design and control a wearable power-assisted system that integrates a human’s intellect as the control command. The system in this work consists of an inner exoskeleton and an outer exoskeleton. The inner s...

Many countries are now facing problems associate to an aging population. Therefore, using robotics technologies to support daily life of elderly people and patients is becoming an important research topic. In my talk, I will introduce our newly developed exoskeleton robot, and show that humanoid control methods can be used to control the exoskeleton robot for assisting human movements.

We report a case of Klinefelter's syndrome owing to maternal meiotic error associated with triphalangeal thumb and delta phalanx bilaterally. There are no previous reports of similar cases and triphalangism with delta phalanx abnormalities of both thumbs might therefore be considered a further, but rare, manifestation of this aneuploidy.

Assisting human locomotion with ankle exoskeletons is a complicated task, requiring consideration of both biological and device contributions to assisted joint mechanics. Assistance techniques have typically involved some combination of work input and torque support. The complex interaction that arises between the exoskeleton and human neuromuscular system, however, makes it difficult to unders...

We present experimental data for an ankle exoskeleton device that provides a metabolic benefit during running. Intuitively, there is an optimal level of power than any particular human can accept and use to benefit walking or running, which is a function of both the particular human and selected gait speed. In this paper, we will present theoretical modeling results to explain recent data for t...

Triphalangeal thumb is characterized by the interposition of an extra-phalanx between two normal ones. In this article the authors present the case of a 24-year-old man with bilateral triphalangeal thumb of opposable type, without any other associated anomaly or genetic syndrome. The patient had triangular delta extra-phalanxes that caused ulnar deviation of both thumbs. Surgical procedure for ...

ABSTRACT Exoskeletons are a new class of articulated mechanical systems whose performance is realized while in intimate contact with the human user. The overall performance depends on many factors including selection of architecture, device, parameters and the nature of the coupling to the human, offering numerous challenges to...

simultaneous dislocation of both interphalangeal (ip) joints of same finger is a highly uncommon finding. and dislocation of metacarpophalangeal (mcp) joint along with interphalangeal joints of thumb are reported in literatures if, scarcely. here we are reporting the three cases, comprising of double dislocation of ip joints in little finger in two patients and simultaneous mcp and ip joint dis...

1696 M ost people are aware that insects are crunchy on the outside. What they don't always realize is that the external crunchy parts form the animal's skeleton, and that this body design makes the apparently simple process of growing extremely complex. In addition to providing a barrier against desiccation and protection from mechanical injury, an insect's external skeleton (exoskeleton) does...
