Test-retest reliability of postural control measures in healthy secondary school pupils: insights from the MOVE12 pilot study

open access: yesFrontiers in Sports and Active Living
IntroductionPostural control is an essential part of human movement. Measurements of center of pressure displacements by force platform are considered the gold standard for assessing postural control.

Centre-of-mass and minimal speed limits of the great hammerhead [PDF]

open access: yesRoyal Society Open Science, 2020
The great hammerhead is denser than water, and hence relies on hydrodynamic lift to compensate for its lack of buoyancy, and on hydrodynamic moment to compensate for a possible misalignment between centres of mass and buoyancy.

Versatile vector tools for efficient protein screening across multiple expression systems

open access: yesFEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

The Methods of Determining the Centre of Gravity of a Tilting Body on the Upper Ankle Joint and Weighing the Feet of a Living Human

open access: yesApplied Sciences
(1) Background: This paper focuses on the issue of examining the centre of gravity (CoG) of the entire body and its tilting segment at the upper ankle joint. (2) Methods: A custom-built measuring station was used to determine the CoG of the tilting body,

Fuzzy Entropy Metrics for the Analysis of Biomedical Signals: Assessment and Comparison

open access: yesIEEE Access, 2019
Fuzzy entropy (FuzEn) was introduced to alleviate limitations associated with sample entropy (SampEn) in the analysis of physiological signals. Over the past decade, FuzEn-based methods have been widely used in various real-world biomedical applications.

A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐

Comparison of centre of gravity and centre of pressure patterns in the golf swing [PDF]

open access: yesEuropean Journal of Sport Science, 2016
AbstractAnalysing the centre of pressure (COP) and centre of gravity (COG) could reveal stabilising strategies used by golfers throughout the golf swing. This study identified and compared golfers’ COP and COG patterns throughout the golf swing in medial–lateral (ML) and anterior–posterior (AP) directions using principal component analysis (PCA) and ...

Discordance Between Systemic Lupus Erythematosus Disease Activity Index Domain Weights and Their Association With Organ Damage Accrual

open access: yesArthritis Care &Research, EarlyView.
Objective Studies of damage accrual in patients with systemic lupus erythematosus (SLE) show associations with disease activity measured by the SLE Disease Activity Index 2000 (SLEDAI‐2K), but these associations are imperfect. SLEDAI scores are powerfully influenced by weightings (1–8) assigned to each domain.

Control and Correction of Horse Rider's Body Posture

open access: yesCentral European Journal of Sport Sciences and Medicine, 2014
Centre of gravity represents the point where the net force of gravity of all the body parts is applied. Balance is a specific state of the postural control system, being a vertical orientation of human body maintained through balancing the forces and ...
