Objectives: The purpose of this study was to compare scapular kinematics during elevation phase of abduction, flexion, and scapular plane elevation phase between fifteen persons with shoulder impingement syndrome (SIS) and thirteen persons without it. Methods: Values of scapular kinematics include scapular superior and lateral translations, upward rotation, external rotation, and posterior t...

Phase angle (PhA), a parameter of bioelectrical impedance analysis, is a well-known predictor of morbidity and mortality in various diseases. The causes of decreased PhA are, however, not yet completely understood. We therefore investigated determinants of PhA in 777 hospitalised patients in a retrospective analysis. PhA was assessed by bioelectrical impedance analysis at 50 KHz. Subjective glo...

We show that a classical imaging criterion based on angular dependence of small-angle phase can be applied to any system composed of planar, uniform media to determine if it is a flat lens capable of forming a real paraxial image and to estimate the image location. The real paraxial image location obtained by this method shows agreement with past demonstrations of far-field flat-lens imaging an...

Phase angle shift between the current and voltage with frequency has been reported for a single phosphoric acid fuel cell in the cell temperature from 100 °C to 160 °C and the humidifier temperature from 40 °C to 90 °C. An electrochemical workbench is employed to find the shift. The figure of phase angle shift shows a peak in high humidifier temperatures. The peak in phase angle shift directs t...

In this paper we discuss further properties of 2D correlation spectroscopy using the global phase angle intensity normalization method. The 2D global phase angle analysis method has been shown to discriminate against arbitrary signal amplitude changes not related to real correlation intensities. We have confirmed that the positive or negative sign of a global phase angle 2D correlation peak is ...

Background. Archery is a precision sport that requires high levels of consistency and reproducibility in the shooting movement to achieve the highest score. Objectives. This study aimed to compare and correlate the shooting time characteristics and shooting posture on the archery shooting performance of high- and low-performance archers. Methods. Terengganu state team and Malaysia Pahang Spor...

objective(s)bioelectrical impedance is the measure of impedance of the body. impedance consists of electric resistance and reactance. phase angle (pa) is the tan value of the ratio of reactance versus electric resistance. pa depends on cell membrane integrity and on body cell mass. there exists a correlation between pa values and body cell mass.the objective of this study was to compare the pa ...

With the purpose to establish a relationship between physical characteristics of the players and biomechanical variables of service in lawn tennis present study was structured. For the purpose of the study twelve intervarsity level players were recruited as the subjects. A camcorder was used to video record the movement of the subjects. 2D Data were collected from movement onset to the follow-t...

Bioelectrical impedance phase angle has been recommended as a tool to assess nutrition state, but there are no measuring devices have been specially designed for hospital residents. In this study, a system was established for the measurement of bioelectrical impedance phase angle. The electrical composition, calculation method and measuring method of this system are presented in this paper. Exp...
