Fast bowling in cricket involves a complex multiarticular action performed at high speed. Functional movement variability plays an important role in helping the performer to maintain the consistency of performance outcomes, although this has not previously been examined in cricket fast bowling in relation to…

'David Howard' 'John Y Goulermas' 'Christine Smith' 'Julie Rigby'] Background In the evaluation of upper limb impairment post stroke there remains a gap between detailed kinematic analyses with expensive motion capturing systems and common clinical assessment tests. In particular, although many clinical tests evaluate…

'Julio Tous-Fajardo' 'Ben Jones' 'Gerard Moras'] The aim of this study was to identify the changes in movement variability and movement velocity during a six-week training period using a resistance horizontal forward-backward task without (NOBALL) or with (BALL) the constraint of catching and throwing a rugby ball in…

Human movement variability, the natural fluctuation in motor performance across repeated tasks, is a fundamental characteristic of healthy biological systems, and its alteration is a hallmark of neurological dysfunction. The use of non-linear measures provides a powerful suite of complementary tools for capturing the…

In many daily jobs, repetitive arm movements are performed for extended periods of time under continuous cognitive demands. Even highly monotonous tasks exhibit an inherent motor variability and subtle fluctuations in movement stability. Variability and stability are different aspects of system dynamics, whose…

'Xavier García-Massó' 'Israel Villarrasa-Sapiña' 'Cristina Menescardi'] Motor variability is a prominent feature of the human movement that, nowadays, can be easily measured through different sensors and analyzed using different types of variables, and it seems to be related to functional and adaptative motor behavior.…

Low back pain (LBP) affects the majority of the worldwide population at some point during their lifetime . Understandably, LBP can have a substantial effect on the quality of life of those affected . People with LBP move differently than pain free individuals . However, the underlying mechanisms of motor adaptations to…

Humans exhibit considerable motor variability even across trivial reaching movements. This variability can be separated into specific kinematic components such as extent and direction, which are thought to be governed by distinct neural processes. Here, we report that individual subjects exhibit different magnitudes of…

Motor Function Authors: ['Shashwat Kumar' 'Arafat Rahman' 'Robert Gutiérrez' 'Sarah Livermon' 'Allison McCrady' 'Silvia S. Blemker' 'Rebecca J. Scharf' 'Anuj Srivastava' 'Laura E. Barnes'] Clinical assessments for neuromuscular disorders, such as Spinal Muscular Atrophy (SMA) and Duchenne Muscular Dystrophy (DMD)…

'Allison McCrady' 'Silvia Blemker' 'Rebecca J. Scharf' 'Mehdi Boukhechba' 'Laura E. Barnes'] Neuromuscular disorders, such as (SMA) and Duchenne Muscular Dystrophy (DMD), cause progressive muscular degeneration and loss of motor function for 1 in 6,000 children. Traditional upper limb motor function assessments do not…

—Functional variability in both gray matter (GM) and white matter (WM) is closely associated with human brain cognitive and developmental processes, and is commonly assessed using functional connectivity (FC). However, as a correlationbased approach, FC captures the co-fluctuation between brain regions rather than the…

Moving about in the world during daily life requires executing and successfully shifting between a variety of functional tasks, such as arising from a chair or bed, walking, turning, and navigating stairs, etc. Moreover, moving about during daily life requires not only navigating between different functional tasks but…

Assessing human movement is essential for diagnosing and monitoring movement-related conditions. Timed function tests (TFTs) are among the most widespread assessments due to their speed and simplicity. However, TFTs cannot capture disease-specific movement patterns. Recent advances in smartphone video-based…

The ultimate goal of any upper-limb neurorehabilitation procedure is to improve upper-limb functioning in daily life. While clinic-based assessments provide an assessment of what a patient can do, they do not completely reflect what a patient does in his/her daily life. The compensatory use of the less affected…

The way we move changes throughout our lifetime and often we move less as we age. Sometimes this slowdown is due to normal aging, other times the changes are caused by medical issues, such as stroke. The whole repertoire of human motion is enabled by unseen forces applied by our muscles and controlled by our complex…

In children with unilateral cerebral palsy (uCP), the corticospinal tract (CST) wiring patterns may differ (contralateral, ipsilateral or bilateral), partially determining motor deficits. However, the impact of such CST wiring on functional connectivity remains unknown. Here, we explored differences in functional…

RNA droplets assembled from co-transcriptionally folded nanostructures have recently emerged as a promising platform for constructing protocells and minimal synthetic cell models. In these systems, a custom-designed DNA template encodes an RNA nanostar, which is produced by transcription and self-assembles into…

Functional magnetic resonance imaging (fMRI) has been widely utilized to study the motor deficits and rehabilitation following stroke. In particular, functional connectivity(FC) analyses with fMRI at rest can be employed to reveal the neural connectivity rationale behind this post-stroke motor function impairment and…

Objective: Brain-Computer Interfaces (BCIs) enable the control of external devices by decoding user intentions from electroencephalography (EEG). However, substantial EEG variability within and between users remains a major challenge. To better understand this variability, we propose interpretable metrics that…
