Article Synopsis
  • The study explored how structured deep breathing (SDB) and natural deep breathing (NDB) affect heart rate variability (HRV) and blood pressure (BP) in older adults living independently.
  • Twenty-six older adults were randomly divided into two groups (SDB and NDB) and were evaluated for HRV and BP before, during, and after the breathing exercises.
  • Results indicated that both breathing techniques significantly improved HRV measures, enhancing parasympathetic activity without impacting blood pressure, suggesting that deep breathing can be a simple and effective way to support healthy aging.

Objective: Evaluating pain in individuals with dementia can be difficult when verbal communication is limited. Vocalization has emerged as a potential avenue for assessments of pain in nonverbal populations. This study aimed to evaluate if physiological assessments of vocalization were correlated with observational assessments of pain during routine blood tests for persons with dementia.

Background: Exercise and cognitive training have been shown to induce neuroplastic changes and modulate cognitive function following stroke. However, it remains unclear whether hybridized exercise-cognitive training facilitates cortical activity and further influences cognitive function after stroke.

Objective: The study aimed to investigate the effects of 2 hybridized exercise-cognitive trainings on neuroplastic changes and behavioral outcomes in stroke survivors with mild cognitive decline.

Wearable inertial sensors have gradually been used as an objective technology for biomechanical assessments of both healthy and pathological movement patterns. This paper used foot-worn sensors for characterizing the spatiotemporal characteristics of walking and turning between older fallers and nonfallers. Thirty community-dwelling older fallers and 30 older nonfallers performed 10-m straight walking, turned 180° around a cone, and then walked 10-m back to the starting point.

Purpose: The objectives are to evaluate the effects of a sequential combination of aerobic exercise and cognitive training, compared with exercise or cognitive training alone, on cognitive function, physical function, daily function, quality of life, and social participation in stroke survivors with cognitive impairment.

Methods: This is a single-blind, parallel, randomized controlled trial. Stroke patients with mild cognitive impairment (n = 56) were randomly assigned to aerobic exercise training (n = 18), computerized cognitive training (n = 18), and the sequential combination of aerobic exercise and computerized cognitive training (n = 20) group.

Stroke and cognitive impairment are common in older population. They often occur together and their combined effects significantly increase disability in both basic (BADLs) and instrumental (IADLs) activities of daily living. We investigated the individual and combined impacts of stroke and cognitive impairment on BADLs and IADLs.

Background: A near-fall is defined as a loss of balance that would result in a fall if sufficient balance recovery manoeuvres are not executed. Compared to falls, near-falls and its associated balance recovery manoeuvres have been understudied. Older adults may not recognise a near-fall or identify the use of their balance recovery manoeuvres to prevent a fall.

Background: The goal of valgus knee brace treatment is to reduce medial knee joint loading during walking, often indicated by external knee adduction moment (KAM) measures. However, existing healthy-subjects studies have been equivocal in demonstrating KAM reduction with valgus knee bracing.

Research Question: What are the immediate effects of valgus bracing at different tension levels on KAM during walking at a controlled speed and does body height modify the brace-KAM associations?

Methods: Data from 32 knee-healthy participants were analysed in this randomized crossover trial.

Background: Previous studies have reported good test-retest reliability for peak knee adduction moment (KAM) during walking. However, reliability of other KAM measurements has not been established.

Research Question: What is the test-retest reliability of peak KAM, KAM impulse, and KAM loading rate measurements during walking in knee-healthy individuals?

Methods: Data from 32 knee-healthy participants were analysed in this test-retest reliability study.

Phosphorylation, a major posttranslational modification of proteins, plays an important role in protein activity and cell signaling. However, it is difficult to detect protein phosphorylation because of its low abundance and the fact that the analysis can be hindered by the presence of highly abundant non-phosphoproteins. In order to reduce the sample complexity and improve the efficiency of identification of phosphopeptides, aliphatic hydroxy acid-modified metal oxide chromatography (HAMMOC) was utilized to enrich phosphopeptides from a murine macrophage cell lysate.

Purpose: Cognitive decline after stroke is highly associated with functional disability. Empirical evidence shows that exercise combined cognitive training may induce neuroplastic changes that modulate cognitive function. However, it is unclear whether hybridized exercise-cognitive training can facilitate cortical activity and physiological outcome measures and further influence on the cognitive function after stroke.

Background/study Context: A manipulation check was used to investigate whether there is an age-related difference in the adherence to specific external- and internal-focus instructional constraints.

Methods: Participants stood on a force platform and were to maintain a feedback cursor (representing their center of pressure) along the horizontal direction, within a target on a computer monitor. Trials were conducted with either an external focus of attention (keeping the feedback cursor within the target) or an internal focus of attention (keeping the weight evenly distributed between both legs).

Optimal sensorimotor integration is needed to maintain the precision of a visuomotor postural task. Furthermore, cognitive resources have been suggested to be involved in maintaining balance, especially in older adults. This study investigated how older and younger adults differed in employing sensorimotor strategies in a dual-task situation.

A light finger touch can stabilize posture despite it not providing enough force to create mechanical support. The underlying mechanism may be due to the finger touch providing information in the axis with the greatest instability. The most appropriate way to test this hypothesis is a dual-axis paradigm, i.

Sensory information from our eyes, skin and muscles helps guide and correct balance. Less appreciated, however, is that delays in the transmission of sensory information between our eyes, limbs and central nervous system can exceed several 10s of milliseconds. Investigating how these time-delayed sensory signals influence balance control is central to understanding the postural system.
