Phase angle variability on bleeding risks in hemodialysis patients.

Background: This study investigated the association between Phase Angle (PhA), measured by bioelectrical impedance analysis, and bleeding risk in hemodialysis patients to evaluate PhA as a predictive marker for bleeding events.

Methods: This retrospective cohort study included 102 hemodialysis patients who underwent PhA measurements between July 2019 and April 2024. Demographic data, medical histories, dialysis parameters, and bleeding events were collected.

Rehabilitation Exercises to Induce Balanced Scapular Muscle Activity in an Anti-gravity Posture.

[Purpose] The purpose of this study was to compare the intramuscular balance ratios of the upper trapezius muscle (UT) and the lower trapezius muscle (LT), and the intermuscular balance ratios of the UT and the serratus anterior muscle (SA) among prone extension (ProExt), prone horizontal abduction with external rotation (ProHAbd), forward flexion in the side-lying position (SideFlex), side-lying external rotation (SideEr), shoulder flexion with glenohumeral horizontal abduction load (FlexBand), and shoulder flexion with glenohumeral horizontal adduction load (FlexBall) in the standing posture. [Methods] The electromyographic (EMG) activities of the UT, LT and SA were measured during the tasks. The percentage of maximum voluntary isometric contraction (%MVIC) was calculated for each muscle, and the UT/LT ratios and the UT/SA ratios were compared among the tasks.
