Feasibility of predicting functional decline in the elderly through key posture information during sit-to-stand movement
This study preliminarily demonstrates that eigenvalues can be used to detect STS patterns and compensation strategies adopted by individuals with different capacities. Our machine learning model has excellent predictive accuracy and may be used to develop inexpensive and effective systems to help caregivers to continuously monitor STS patterns and compensation strategies of elderly individuals as warning signs of functional decline.PMID:38547793 | DOI:10.1016/j.humov.2024.103212 (Source: Human Movement Science)

Joint kinematics and SPM analysis of gait in children with and without Down syndrome
Hum Mov Sci. 2024 Mar 22;95:103213. doi: 10.1016/j.humov.2024.103213. Online ahead of print.ABSTRACTBACKGROUND: Individuals with Down syndrome (DS) walk with altered gait patterns compared to their typically developing (TD) peers. While walking at faster speeds and with external ankle load, preadolescents with DS demonstrate spatiotemporal and kinetic improvements. However, evidence of joint kinematic adjustments is unknown, which is imperative for targeted rehabilitation design.RESEARCH QUESTION: How does increasing walking speed and adding ankle load affect the joint kinematics of children with and without DS during over...

The effect of inherent and incidental constraints on bimanual force control in simulated Martian gravity
Hum Mov Sci. 2024 Mar 20;95:103199. doi: 10.1016/j.humov.2024.103199. Online ahead of print.ABSTRACTThe ability to coordinate actions between the limbs is important for many operationally relevant tasks associated with space exploration. A future milestone in space exploration is sending humans to Mars. Therefore, an experiment was designed to examine the influence of inherent and incidental constraints on the stability characteristics associated with the bimanual control of force in simulated Martian gravity. A head-up tilt (HUT)/head-down tilt (HDT) paradigm was used to simulate gravity on Mars (22.3° HUT). Right limb d...

Impaired performance of rapid grip in people with Parkinson's disease and motor segmentation
Hum Mov Sci. 2024 Mar 19;95:103201. doi: 10.1016/j.humov.2024.103201. Online ahead of print.ABSTRACTBradykinesia, or slow movement, is a defining symptom of Parkinson's disease (PD), but the underlying neuromechanical deficits that lead to this slowness remain unclear. People with PD often have impaired rates of motor output accompanied by disruptions in neuromuscular excitation, causing abnormal, segmented, force-time curves. Previous investigations using single-joint models indicate that agonist electromyogram (EMG) silent periods cause motor segmentation. It is unknown whether motor segmentation is evident in more anato...

An analysis of the effect of motor experience on muscle synergy in the badminton jump smash
Hum Mov Sci. 2024 Mar 19;95:103209. doi: 10.1016/j.humov.2024.103209. Online ahead of print.ABSTRACTThe jump smash is badminton's most aggressive technical manoeuvre, which is often the key to winning a match. This paper aims to explore the neuromuscular control strategies of advanced and beginner players when jumping smash in different ways. Collecting sEMG and kinematic data from 18 subjects with different motor experiences when jumping smash. Nonnegative Matrix Factorization and K-Means clustering were used to extract muscle synergies and exclude irrelevant combined synergies. Uncontrolled manifold analysis was then use...

Mechanical environment influences muscle activity during infant rolling
Hum Mov Sci. 2024 Mar 13;95:103208. doi: 10.1016/j.humov.2024.103208. Online ahead of print.ABSTRACTAn infant's musculoskeletal and motor development is largely affected by their environment. Understanding how different mechanical environments affect an infant's movements and muscle use is necessary to inform the juvenile products industry and reduce incidents involving inclined nursery products each year. The purpose of this study was to determine how the coordinated movements and corresponding muscle activation patterns are affected by different mechanical environments, specifically the back incline angle.
