NCT07077460
Previous studies have found that graded motor imagery (GMI) training can provide continuous activation of the cerebral cortex compared to traditional rehabilitation therapy. One of the steps in this strategy, mirror therapy, has also been widely used in the clinical treatment of hemiplegic patients. Also, comparing with traditional rehabilitation treatments, mirror therapy can continuously provide cortical activation. Besides, several studies indicated that game-based interventions contribute to brain activation in the elderly due to their interest can improve users' motivation in the training program execution. In addition, force control training has positive effects on hand dexterity, and specific doses of motor control training not only improve motor function but also have positive effects on brain function. Currently, hand function training primarily focuses on range of motion, strength, and hand function, although there is comparatively less emphasis on enhancing both force control and brain function. Moreover, studies related to mirror therapy has primarily focused on the execution of functional movements, but has not explored whether hand strength control training can achieve the same training effects on the affected or non-dominant side through the concept of mirror therapy. Furthermore, the effects of combining a hand strength control system with a synchronous contralateral clip-on force feedback device on brain activation and hand function have not yet been studied. Therefore, this study aimed to investigate the effects of integration a finger force control training system with synchronous contralateral force feedback and mirror visual feedback device on brain activation and hand function, aiming to develop a clinically applicable hand rehabilitation system. Additionally, visual feedback from force control training in our study is through the hints displayed virtually on the game interface of the tablet, which were represented as the height of the targets, not as typical as actual movement-based mirror therapy or task-based mirror therapy. Therefore, the purpose of the study is to understand the differences among training effects of integrating Graded-Pressure Haptic Device-TiPR closed-loop system and MVF; MVF and force control training, as well as isolated force control training, and to explore the training effects on hand strength, hand function and brain activation.

NCT03818802

NCT06801782
The goal of this randomized controlled trial is to evaluate the efficacy of attention and executive function training on prospective memory (PM) and executive functions in patients with Parkinson's disease and mild cognitive impairment (PD-MCI) and compare their performance to healthy volunteers. The study aims to determine whether immersive virtual reality (iVR) training can improve PM and executive function performance in PD-MCI patients, whether the effects of training are maintained over time, and how the PM and executive function performance of PD-MCI patients compares to that of healthy volunteers. Participants in the training group engage in real-life scenario exercises focused on planning, shifting, and updating tasks, while those in the placebo group perform simpler daily tasks with lower cognitive demands. Healthy volunteers serve as an additional control group. All sessions are conducted remotely using telemedicine and iVR headsets over a 4-week period. Outcome measures, including PM and executive function performance, are assessed at baseline, post-training, and a 2-month follow-up to evaluate the intervention's effectiveness and compare results across groups.
NCT06435078
previous studies indicated that sensory input can have positive impacts on finger force control in the elderly. Additionally, according to previous reports, apart from pharmacotherapy, nonpharmacologic interventions, such as psychosocial-environmental treatments, are emerging for the behavior and affective symptoms in AD . Moreover, enhanced finger force control and coordination lead to better hand dexterity and is believed to eventually improve life independence in the healthy elderly and the elderly with AD. Therefore, this study aims to develop novel virtual visual and haptic stimulation systems for the elderly to enhance their finger force control.
NCT03536871
To understand the effects of a novel dietary supplement when used in conjunction with a healthy lifestyle exercise program and to define biomarkers that are specific to sarcopenia. A primary aim in the present study is to determine whether a relationship exists between positive changes in body composition through increases in lean mass and reductions in body fat following oral supplementation of naturally occurring food components in combination with exercise. The purpose of the present study is to examine the effects of a multi-nutrient supplement in combination with an endurance and resistance based exercise intervention in a cohort of older adult men with varying degrees of sarcopenia as compared to younger male controls (McMaster/CIHR/Exerkine project). A sub-purpose nested within the study is to provide serum and muscle samples for use in an aging/sarcopenia biomarker discovery study taken at pre-intervention for the young and older men (Buck Institute/Astellas project).

NCT02440100
This is an investigator-and-subject blind, phase 1 study to characterize the safety, tolerability, pharmacokinetics and central and peripheral pharmacodynamics of 14-day repeated ascending doses of PF-06648671 once a day in healthy adults (part 1) and repeated doses at the maximum tolerated dose (MTD) defined in part 1 in healthy elderly subjects (part 2). The study also include an optional cohort (part 3) to evaluate the drug interaction between PF-06648671 at MTD and CYP3A probe, midazolam
NCT02342652

NCT02376270
The population is aging worldwide, which requires more attention to health needs and leads to a dramatic increase in health care costs. Prevention or delay of onset of disorders associated with aging is needed. Dietary intake of pectin, a dietary fiber, may have beneficial effects on gut health parameters, i.e. intestinal barrier function, immune function and microbial composition. As intestinal barrier function may be compromised in the elderly we will investigate whether the effects of pectin on selected parameters of gut health differ between young vs. older individuals. The primary objective of this study is to investigate the effects of aging on pectin-induced changes in intestinal permeability. Furthermore, this study has seven secondary objectives. This study conforms to a randomized, double-blind and placebo-controlled design including two parallel arms.The study population consists of Healthy human volunteers (male and female), 18-40 and 65-75 years old, BMI 20-30 kg/m2. One group will receive 7.5 grams of pectin supplements twice daily for four weeks. A second group will receive 7.5 grams of placebo supplements twice daily for four weeks. Before and after the supplementation period, several measurements will take place. The main study parameter is the change in urinary sugar excretion ratio before and after the intervention period.

NCT01188382
Objective. The intracranial pressure and cerebrospinal outflow resistance are essential parameters to describe the cerebrospinal fluid dynamic system. Outflow resistance effects intracranial pressure, pulse amplitudes, cerebrospinal fluid absorption as well as the compliance of the system. The objective of this study was to determine the reference values in the elderly. Methods. Elderly people (60-82 years), considering themselves healthy, were recruited through an ad in the local paper. All were evaluated with a 3 Tesla magnetic resonance imaging apparatus. Subjects were eligible if they did not have any psychiatric or neurological disorder or signs of advanced atherosclerotic disease. Intracranial pressure and outflow resistance were determined by a constant pressure infusion method with the patient in the supine position. The study population consisted of 40 subjects (mean age 70 years; 23 women).
