Effects of electrical stimulation in vestibular cortex areas in humans.
2010
The case of a patient with focal epilepsy is reported who underwent presurgical evaluation by stereotactic intracranial electroencephalographic (EEG) recording. A subdural semi-grid electrode, consisting of three multi-channel strip electrodes, was implanted over the temporal lobe and temporo-occipital region; one multi-channel depth electrode was applied towards the posterior insular cortex. During electrical stimulation and EEG monitoring eye movements were recorded by 3-D video-oculography. Stimulation of the medial temporal gyrus induced blurring of vision and horizontal nystagmus. Stimulation of the superior temporal gyrus with low intensities also induced blurring of vision and a simi…
Impact of Visual Biofeedback of Trunk Sway Smoothness on Motor Learning during Unipedal Stance.
2020
The assessment of trunk sway smoothness using an accelerometer sensor embedded in a smartphone could be a biomarker for tracking motor learning. This study aimed to determine the reliability of trunk sway smoothness and the effect of visual biofeedback of sway smoothness on motor learning in healthy people during unipedal stance training using an iPhone 5 measurement system. In the first experiment, trunk sway smoothness in the reliability group (n = 11) was assessed on two days, separated by one week. In the second, the biofeedback group (n = 12) and no-biofeedback group (n = 12) were compared during 7 days of unipedal stance test training and one more day of retention (without biofeedback…
Health and Physical Function Predicting Strength and Balance Training Adoption: A Community-Based Study Among Individuals Aged 75 and Older
2013
This study was conducted to determine the characteristics of health and physical function that are associated with not starting strength and balance training (SBT). The study population consisted of 339 community-dwelling individuals (75–98 years, 72% female). As part of a population-based intervention study they received comprehensive geriatric assessment, physical activity counseling, and had the opportunity to take part in SBT at the gym once a week. Compared with the SBT-adopters, the nonadopters (n = 157, 46%) were older and less physically active, had more comorbidities and lower cognitive abilities, more often had sedative load of drugs or were at the risk of malnutrition, had lower …
The Role of Textured Material in Supporting Perceptual-Motor Functions
2013
Simple deformation of the skin surface with textured materials can improve human perceptual-motor performance. The implications of these findings are inexpensive, adaptable and easily integrated clothing, equipment and tools for improving perceptual-motor functionality. However, some clarification is needed because mixed results have been reported in the literature, highlighting positive, absent and/or negative effects of added texture on measures of perceptual-motor performance. Therefore the aim of this study was to evaluate the efficacy of textured materials for enhancing perceptual-motor functionality. The systematic review uncovered two variables suitable for sub-group analysis within …
Effectiveness and Estimation of Cost-Effectiveness of a Group-Based Multicomponent Physical Exercise Programme on Risk of Falling and Frailty in Comm…
2019
This study analyses the effectiveness and cost-effectiveness of a group-based multicomponent physical exercise programme aimed at reducing the risk of falling and frailty in community-dwelling older adults. This is a pretest&ndash
A one-year proprioceptive exercise programme reduces the incidence of falls in community-dwelling elderly people: A before-after non-randomised inter…
2016
Abstract Background The risk of falls increases with age. Balance alteration and polypharmacy are independent contributors to an increased risk of falls. Objective The primary aim was to assess whether a proprioceptive exercise programme reduces the incidence of falls. A secondary aim was to assess the association between drugs and falls. Design This was a before–after non-randomised intervention study. Participants The study recruited independent and cognitively intact community-dwelling people aged over 69 years, from December 2012 to May 2014. Methods The intervention was done by a nurse and consisted of a monthly supervised group session of proprioceptive training for 1 year, supplement…
Activity of Thigh Muscles During Static and Dynamic Stances in Stroke Patients: A Pilot Case-Control Study
2014
Impaired postural control is a key characteristic of mobility problems in stroke patients and has great impact on the incidence of falls and on the level of independence in activities of daily living. The role played by the thigh muscles in balance impairment in stroke patients has not been sufficiently investigated. This study investigated the activities of the thigh muscles in stroke patients during standing balance manipulations.Ten stroke patients and 15 healthy subjects performed 5 upright standing tasks on a force platform: normal standing with eyes open, normal standing with eyes closed, feet together, semi-tandem standing, and a dynamic measurement along a predefined route. The post…
Self-Reported Hearing Status Is Associated with Lower Limb Physical Performance, Perceived Mobility, and Activities of Daily Living in Older Communit…
2015
BACKGROUND: Poor hearing is common in older adults and it may have negative consequences which extend beyond communication. OBJECTIVES: To explore the associations of self-reported hearing problems with physical performance and self-reported difficulties in mobility and activities of daily living (ADL) in community-dwelling older adults. DESIGN: Cross-sectional cohort study SETTING: Community PARTICIPANTS: 848 men and women aged 75-90 years MEASUREMENTS: Structured face-to-face interviews to assess perceived hearing problems in the presence of noise, mobility difficulties (moving indoors, stair-climbing, 0.5 km walk and 2 km walk) and difficulties in ADLs and instrumental ADLs. The Short Ph…
Effects of dual task difficulty in motor and cognitive performance: Differences between adults and adolescents
2017
In the present study our aim was to compare dual-task performance in thirteen adolescents and fifteen young adults while concurrently performing a cognitive and a motor task. The postural control variables were obtained under three different conditions: i) bipedal stance, ii) tandem stance and iii) unipedal stance. The cognitive task consisted of a backward digit span test in which the participants were asked to memorize a sequence of numbers and then repeat the number in reverse order at three different difficulty levels (i.e. with 3, 4 and 5 digits). The difficulty of the cognitive task was seen to have different effects on adolescents and young adults. Adolescents seem to prioritize post…
Effects of A Dual-Task Intervention in Postural Control and Cognitive Performance in Adolescents.
2019
The aim was to assess dual- versus single-task training for motor performance and cognitive performance in adolescents. Two experiments were performed. In the first, 30 adolescents were randomized to three groups to determine the effect of dual-task difficulty on postural control: α-scaling and root mean square (RMS). In the second, 20 adolescents were randomized to two groups to determine the effect of dual-task practice to improve working memory. RMS in the post-test was lower than the pre-test in both dual-task groups, while α-scaling was lower in post-test than pre-test only in the high-difficulty dual-task group. A practice effect was observed on the percentage of correct answers only …
