This study aimed to investigate the association between a virtual reality (VR) intervention program and cognitive, brain physical functions in high-risk older adults. In randomized controlled trial, we enrolled 68 individuals with mild cognitive impairment (MCI). The MCI diagnosis was based on medical evaluations through clinical interview conducted by dementia specialist. Cognitive assessments were performed neuropsychologists according standardized methods, including Mini-Mental State...
We investigated the effectiveness of virtual-reality-based cognitive training (VRCT) and exercise on brain, cognitive, physical activity older adults with mild impairment (MCI).This study included 99 participants (70.8 ± 5.4) MCI in VRCT, exercise, control groups. The VRCT consisted a series games targeting different brain functions such as executive function, memory, attention. Twenty-four sessions (three days/week) were performed, each session was 100 min long. Exercise intervention...
Our study examined the association between chronotype, daily physical activity, and estimated risk of dementia in 170 community-dwelling older adults. Chronotype was assessed with Horne–Östberg Morningness–Eveningness Questionnaire (MEQ). Daily activity (of over 3 METs) measured a tri-axial accelerometer. The Korean version Mini-Mental State Examination (K-MMSE) used to measure dementia. evening low were positively associated each other. participants alongside preference had 3.05 3.67 times...
Background: This study examines the relationship between physical and mental function frailty, independently in conjunction with polypharmacy, among older adults. Methods: cross-sectional consisted of 368 participants aged ≥60 years. The were categorized into either robust or frail groups using Fried’s frailty phenotype. Physical functions assessed grip strength, gait speed, Timed Up Go (TUG), Five Chair Sit to Stand Test (FCSST) Six-Minute Walk (SMWT). Mental cognitive depression. Cognitive...
Current step-count estimation techniques use either an accelerometer or gyroscope sensors to calculate the number of steps. However, because smartphones unfixed placement and direction, their accuracy is insufficient. It necessary consider impact carrying position on pedometer algorithm, people carry in various positions. Therefore, this study proposes a carrying-position independent ensemble step-counting algorithm suitable for unconstrained different The proposed comprises classification...
The purpose of this study is to examine how physical function, activity, and sleep are related depressive symptoms in older adults using a nonlinear model. participants were 283 Korean aged 65 who met the inclusion criteria. Depressive measured shortened version Geriatric Depression Scale (SGDS-K). Physical activity time objectively quantified by continuously monitoring over 20 consecutive days triaxial accelerometer. function was evaluated five distinct measurements: grip strength, gait...
This study investigated the effectiveness of electrical muscle stimulation (EMS) with resistance exercise training (ERT) and (RT) on physical brain function in middle-aged older women. Method: Forty-eight participants were randomly allocated into three groups: (i) ERT (n = 16), (ii) RT (iii) control group 16). The intervention session was 50 min long performed times/week for four weeks. quadriceps setting, straight leg raises, ankle pump exercises while constantly receiving EMS their both...
Alzheimer’s disease (AD) is highly prevalent in dementia, with no specifically effective treatment having yet been discovered. Amyloid plaques are one of the key hallmarks AD. Transgenic mouse models exhibiting disease-like pathology have widely used to study pathophysiology disease. In this study, we showed an age-dependent correlation between cognitive function, pathological findings, and [F-18] Florbetaben (FBB) PET images. Nineteen transgenic mice (12 AD, 7 controls) were for study. We...
Abstract Background Numerous studies have shown that aerobic and resistance exercises, including leisure time physical activity help to reduce the risk of cognitive decline. Recently potential training using immersive virtual reality (VR) has been growing in non‐pharmacological interventions for mild impairment (MCI). However, there are not enough comparing impact two different interventional approaches on cognition brain function especially MCI patients. Therefore, we investigated...
Abstract Background This study aimed to investigate the effectiveness of a combined‐exercise intervention program on cognitive and physical functions. Method In randomized controlled trial, we enrolled 167 individuals with mild impairment (MCI). The definition MCI was based medical evaluations through clinical interview conducted by dementia specialist. Cognitive assessments were performed neuropsychologists according standardized methods, including MMSE frontal function, both at baseline 6...
Abstract Background Given the current lack of evidence for intervention and disease‐modifying treatment Mild cognitive impairment (MCI) dementia, exploring new interventions is important. VR have increasingly gained popularity in psychotherapy behavioral therapy, potential based to improve cognition are also being explored. However, evidences regarding its effect on dementia quite ambiguous. Therefore, we aimed synthesize effects older adults with MCI/ dementia. Method Seventy‐five subjects,...
