In a previous study, we found that wrist circumference, in particular its bone component, was associated with insulin resistance in a population of overweight/obese children. The aim of the present study was to evaluate the intra- and inter-operator variability in wrist circumference measurement in a population of obese children and adolescents. One hundred and two (54 male and 48 female) obese...

BACKGROUND Wrist movements become impaired with disease progression in various neuromuscular disorders. With the development of new therapies, thorough measurement of muscle strength is crucial to document natural disease progression and to assess treatment efficacy. We developed a new dynamometer enabling wrist flexion and extension torque measurement with high sensitivity. The aims of the pre...

[Purpose] The purpose of this study was to compare the measurements of an electrogoniometer with those of the Fisi Metrix program to investigate the reliability and validity of Fisi Metrix assessments of wrist ROM. [Methods] The subjects were eighteen healthy young females. Wrist deviation was measured on images by three raters for measurement of wrist ROM using the Fisi Metrix program. [Result...

Arm size can affect the accuracy of blood pressure (BP) measurement, and "undercuffing" of large upper arms is likely to be a growing problem. Therefore, the authors investigated the relationship between upper arm and wrist readings. Upper arm and wrist circumferences and BP were measured in 261 consecutive patients. Upper arm auscultation and wrist BP was measured in triplicate, rotating measu...

Despite the increasing popularity of blood pressure (BP) wrist monitors for self-BP measurement at home, device validation and the effect of arm position remains an issue. This study focused on the validation of the Omron HEM-609 wrist BP device, including an evaluation of the impact of arm position and pulse pressure on BP measurement validation. Fifty patients at high risk for cardiovascular ...

A reliability study was conducted to determine (a) the intrarater and interrater reliability of goniometric measurement of active and passive wrist motions under clinical conditions and (b) the effect of a therapist's specialization on the reliability of measurement. Randomly paired therapists performed repeated measurements of active and passive wrist motions in 48 subjects who had been referr...

When evaluating general health condition on a patient, heart rate is an essential indicator as it directly representative of the cardiac system state. Continuous measurement methods are required for ambulatory monitoring involved in preliminary diagnostic indicators diseases or stroke. The growing number recent developments wearable devices reflective increasing demand wrist-worn activity track...

BACKGROUND Non-invasive imaging techniques such as magnetic resonance imaging (MRI) provide the ability to evaluate the complex anatomy of bone and soft tissues of the wrist without the use of ionizing radiation. Dynamic instability of wrist--occurring during joint motion--is a complex condition that has assumed increased importance in musculoskeletal medicine. The objective of this study was t...

In this paper we present an identification algorithm for the rigid-body parameters of an industrial ABB robot wrist. The main contributions of our work are 1) the demonstration of rigid-body dynamic identification algorithms on large industrial robots, for which we handle complex internal couplings of the manipulator wrist, as shown in the experiments. 2) the use of the particular non-linear st...

BACKGROUND Abnormalities in motor activity represent a central feature in major depressive disorder. However, measurement issues are poorly understood, limiting the use of objective measurement of motor activity for diagnostics and treatment monitoring. METHODS To improve measurement issues, especially sensor placement, analytic strategies and diurnal effects, we assessed motor activity in de...
