OBJECTIVE To systematically review the effectiveness of workplace interventions for reducing sitting. METHODS Studies published up to April 2009 were identified by literature searches in multiple databases. Studies were included if they were interventions to increase energy expenditure (increase physical activity or decrease sitting); were conducted in a workplace setting; and specifically me...

The research reported in this paper is devoted to the impulse-radar technology when applied for non-intrusive monitoring of elderly persons. Specifically, study focused on a novel approach interpretation data acquired by means multiple sensors, leading determination features be used recognition monitored person’s actions. measurement are first transformed into three-dimensional coordinates perso...

BACKGROUND Sedentary behaviour is a known risk factor for a wide range of chronic diseases. This major health risk is likely to increase given the increasingly sedentary nature of work. AIMS To investigate the prevalence of sedentary behaviour in a sample of UK working-aged adults, across a range of employment sectors. METHODS A cross-sectional survey conducted with organizations throughout...

Prolonged sitting impairs endothelial function in the leg vasculature, and this impairment is thought to be largely mediated by a sustained reduction in blood flow-induced shear stress. Indeed, preventing the marked reduction of shear stress during sitting with local heating abolishes the impairment in popliteal artery endothelial function. Herein, we tested the hypothesis that sitting-induced ...

BACKGROUND Sitting time and breaks in sitting influence cardio-metabolic health. New monitors (e.g. activPAL™) may be more accurate for measurement of sitting time and breaks in sitting although how to optimize measurement accuracy is not yet clear. One important issue is the minimum sitting/upright period (MSUP) to define a new posture. Using the activPAL™, we investigated the effect of variat...

Restless legs syndrome (RLS and also known as Willis-Ekbom disease) is a disorder that's characterized by annoying and sometimes painful sensations in the legs that are brought about by sitting or lying down. These sensations can include creeping, tingling, burning, tugging, or aching in the calves, thighs, or feet. Getting up and moving around is usually the only way to find some relief. Also,...

BACKGROUND Orthostatic tremor (OT) is a high-frequency tremor (13-18 Hz) present in the legs when standing. Underlying disease is found in one-third of OT patients. CASE REPORT We describe an 86-year-old man with progressive shaking of the legs while standing, which disappears immediately after sitting down or while walking. Polymyography confirmed a tremor of the legs (10-11 Hz) while standi...

The problem of active shielding of some domains from the effect of the sources distributed in other domains is considered. The problem can be formulated either in a bounded domain or in an unbounded domain. The active shielding is realized via the implementation of additional sources in such a way that the total contribution of all sources leads to the desirable effect. Mathematically the probl...
