BACKGROUND Four oscillometric devices for self-measurement of blood pressure (SBPM) were evaluated according to the European Society of Hypertension (ESH) international protocol and its 2010 revision in four separate studies. The Omron® M2, Omron M3, and Omron M6 measure blood pressure (BP) at the brachial level, while the Omron R2 measures BP at the wrist level. METHODS The international pro...

We present a dynamic and thermodynamic study of the orientational glass former Freon 113 (1,1,2-trichloro-1,2,2-trifluoroethane, CCl_{2}F-CClF_{2}) in order to analyze its kinetic and thermodynamic fragilities. Freon 113 displays internal molecular degrees of freedom that promote a complex energy landscape. Experimental specific heat and its microscopic origin, the vibrational density of states...

Objective assessment of physical activity (PA) in chronic obstructive pulmonary disease (COPD) is important. We examined the performance of the Omron HJ-720ITC pedometer. A sample of 176 persons with stable COPD wore the Omron and the StepWatch Activity Monitor (SAM) in the clinic and the community. A 4 s step filter in the Omron screens out erroneous intermittent steps; it captures continuous ...

We evaluated an Internet-mediated, pedometer-based program to promote walking in chronic obstructive pulmonary disease (COPD). First, we assessed the accuracy of the Omron HJ-720ITC pedometer (OMRON Healthcare, Inc; Bannockburn, Illinois) in 51 persons with COPD. The Bland-Altman plot showed a median difference of 3 steps (5th and 95th quintiles, -8.0 and 145.0, respectively). We calculated per...

the aim of the study was to develop a non-exercise vo2max predictive model using a physical activity (pa) variable determined by pedometer-determined step counts (sc: steps/day) in active lifestyle men aged between 40 and 65. for this purpose, 69 subjects were used to develop and validate the new model. vo2max was measured using rockport fitness walking test. anthropometric variables were measu...

OBJECTIVE To compare readings obtained using two automated blood pressure (BP) recording devices, BpTRU and Omron 907, in a clinical setting. METHODS Two series of 50 patients attending a hypertension unit for 24-h ambulatory BP monitoring had BP recorded either every 1 or every 2 min using BpTRU and Omron 907 devices with the order of the measurements being randomized. RESULTS No significa...

BACKGROUND Accurate measurement of blood pressure is of utmost importance in hypertension research. In the context of epidemiologic and clinical studies, oscillometric devices offer important advantages to overcome some of the limitations of the auscultatory method. Even though their accuracy has been evaluated in multiple studies in the clinical setting, there is little evidence of their perfo...

BACKGROUND This study compared the validity of a new Omron HJ-303 piezoelectric pedometer and 2 other pedometers (Sportline Traq and Yamax SW200). METHODS To examine the effect of speed, 60 subjects walked on a treadmill at 2, 3, and 4 mph. Twenty subjects also ran at 6, 7, and 8 mph. To test lifestyle activities, 60 subjects performed front-back-side-side stepping, elliptical machine and sta...

OBJECTIVES This study seeks to validate the use of activity monitors to detect and record gait abnormalities, potentially identifying patients with idiopathic normal pressure hydrocephalus (iNPH) prior to the onset of cognitive or urinary symptoms. METHODS This study compared the step counts of four common activity monitors (Omron Step Counter HJ-113, New Lifestyles 2000, Nike Fuelband, and F...

OBJECTIVE Two oscillometric devices, the Microlife WatchBP O3® and the Omron RS6®, designed for self-blood pressure measurement were evaluated according to the European Society of Hypertension (ESH)-International Protocol (IP) Revision 2010 in the obese population. METHODS The Microlife WatchBP O3 measures blood pressure (BP) at the brachial level and the Omron RS6 measures BP at the wrist le...
