The effects of training with isokinetic maximal voluntary knee extensions were studied in stroke patients. Two groups of 10 patients each trained twice a week for 6 weeks. One group trained exclusively eccentric movements and the other exclusively concentric movements. The effects were evaluated from the following tests before and after the training period.(More)

AIMS To determine the inter-rater reliability in scoring sensory and motor function and in defining sensory and motor levels in incomplete spinal cord injury, using the revised 1992 International Standards for Neurological and Functional Classification of Spinal Cord Injury (ISCSCI-92) and to determine the effect on raters agreement of one standardising(More)
The practice-oriented turn in social sciences has implied a series of fundamental consequences and design challenges for HCI in general, and particularly in tangible interaction research. This could be interpreted as a move away from scientific ideals based on a modernist tradition, reflected in four contemporary themes in tangible interaction research. The(More)
In the light of theoretical as well as concrete technical development, we discuss a conceptual shift from an information-centric to an action-centric perspective on tangible interactive technology. We explicitly emphasise the qualities of shareable use, and the importance of designing tangibles that allow for meaningful manipulation and control of the(More)
We present a ubiquitous service environment for teamwork, supported by Active Documents. The environment consists of a physically dressed conference room and a software architecture based on Java and Jini. At the application level, mobile agent technology provide Active Documents that utilise context information and distributed resources to support users.(More)
In the recent developments of human computer interaction, one central challenge has been to find and to explore alternatives to the legacy of the desktop computer paradigm for interaction design. To investigate this issue further we have conducted an analysis on a fascinating piece of machinery often referred to as one of the predecessors of the modern day(More)
BACKGROUND Three million people in Sweden are trained in cardiopulmonary resuscitation (CPR). Whether this training increases the frequency of bystander CPR or the survival rate among persons who have out-of-hospital cardiac arrests has been questioned. METHODS We analyzed a total of 30,381 out-of-hospital cardiac arrests witnessed in Sweden from January(More)
