A novel body weight support system extension: Initial concept and simulation study - Zurich Open Repository and Archive


Pennycott, Andrew; Vallery, Heike; Wyss, Dario; Spindler, Markus; Dewarrat, Antoine; Riener, Robert (2013). A novel body weight support system extension: Initial concept and simulation study. IEEE International Conference on Rehabilitation Robotics. Proceedings, 2013:1-4.

Abstract

Body weight supported treadmill training is an approach to gait rehabilitation following a stroke or spinal cord injury. Although lateral control of balance is an important aspect of walking, many of the currently available body weight support systems have a fixed pulley configuration which can lead to lateral forces being developed in the supporting cables, interfering with the lateral balance task. In this paper, a novel extension for body weight support systems, used for treadmill walking, is presented which features a system of pulleys and trolleys. A model is developed for the device along with a basic feedback controller in order to enable simulation of the concept. The lateral forces induced by the novel system are greatly reduced in comparison to a fixed pulley system. This device has applications in balance training within gait rehabilitation programs.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
