OBJECTIVE To analyze the effects of conventional rehabilitation combined with bilateral force-induced isokinetic arm movement training on paretic upper-limb motor recovery in patients with chronic stroke. DESIGN Single-cohort, pre- and postretention design. SETTING Rehabilitation department at a medical university. PARTICIPANTS Twenty subjects who had unilateral strokes at least 6 months ...

Step frequency and energy expenditure are greater in backward running than in forward running. The differences in the motion of the centre of mass of the body associated with these findings are not known. These differences were measured here on nine trained subjects during backward and forward running steps on a force platform at 3-17 km h(-1). In contrast to previous reports, we found that the...

This article analyses the push and pull factors that bring visitors to the Iranian national parks. The study used a structured questionnaire to collect data on these factors and the socio-demographic profile of the visitors. Survey conducted in Boujagh National Park, an area of 3177 hectares located in the north of the Iran, produced 400 questionnaires. The factor analysis identified four push ...

Over the past ten years or so the need for the measurement of low forces ranging from newtons down to attonewtons has become increasingly important. As we begin to manufacture and manipulate structures on the micrometre to nanometre scale, the forces that are exerted in such processes must be controlled. To control such forces requires some form of measurement, either a direct measurement of th...

The musculoskeletal structure of the foot and ankle has the potential to influence human sprinting performance in complex ways. A large Achilles' tendon moment arm improves the mechanical advantage of the triceps surae but also produces larger shortening velocity during rapid plantarflexion, which detracts from the force-generating capacity of the plantarflexors. The lever arm of the ground rea...

This paper describes a technique called producer-push that enhances the performance of a page-based software distributed shared memory system. Shared data, in software DSM systems, must normally be requested from the node that produced the latest value. Producer-push utilizes the execution history to predict this communication so that the data is pushed to the consumer before it is requested. I...

New technologies enable educators to modify their teaching methods and extend their reach beyond the classroom. One of these methods that can be applied to communicate with students is through the use of push notifications on smartphones. Instead of relying on students to use a spaced learning approach, which is proven to be more efficient than trying to study something in a short period of tim...
