Filter by:The goal of this clinical trial is to learn if a nature-based program has positive effects on the physical and psychosocial health in a group of participants with Parkinson's disease. The main questions it aims to answer are: Will the program improve: - The physical outcomes such as mobility, strength and balance? - The psychosocial health outcomes? Participants will: - Be assessed before and after the program; - Participate in one session per week of the intervention.
This is a randomized, parallel, double-blind clinical trial. The main objective is to compare the efficacy of strength training, multimodal exercise with non-specific exercises and a control group on cognitive functionality and physical composition in subjects over 65 years of age with mild or non existent cognitive impairment currently receiving occupational therapy. The intervention in both groups will be carried out for 30 weeks, with three weekly sessions. Two evaluations will be performed, one pre-intervention and one post-intervention. Cognitive Functionality (Montreal Cognitive Assessment (MOCA) and Lawton and Brody Scale), Sleep quality (Athens insomnia scale and Pittsburgh sleep quality index), physical functionality (Timed up and go (TUG), chair stand test and hand grip test and Short Physical Performance Battery (SPPB)), body composition (Body fat %, skeletal muscle index (SMI), appendicular skeletal muscle (ASM), waist circumference, waist hip ratio, body weight, body mass index (BMI)) will be evaluated.
Accidental falls in older adults are one of the world's major pubic health problem, because of their strong association with injuries and mortality rates. In Quebec, falls are responsible for a high rate of hospitalization (more than 1800 emergency department visits every day) and deaths (more than 10,000 in recent years). Preventing falls is therefore a key mission for health professionals. This research program aims to develop a new clinical approach to the rehabilitation management of the older with a neuro-musculoskeletal disorder and a risk of falling. This program is part of a new partnership project between UQAC and specialized geriatric services at the CIUSSS Saguenay-Lac-St-Jean (La Baie site). These geriatric services admit more than 400 new patients per year, representing a large pool of participants for the new program's development. Specifically, this program has 4 phases: 1) Create a clinical profile of patients in rehabilitation care from specialized geriatric services (ex: reasons for consultation, neuro-musculoskeletal disorders, rates and causes of falls, etc.); 2) to diagnose functional deficits of these patients on different dimensions of functional and physical evaluations, using standardized tests and high-tech instruments (ex: platform of force); 3) determine the effectiveness of a new exercise intervention program (OTAGO) for falls prevention; and 4) Measure client and professional team satisfaction as well as long-term impact of this new approach used to prevent falls. The most significant impact of this new program will be to reduce public health expenditure for care of older adults with balance disorder and risk for falls; and therefore, be implanted in other CIUSSS institutions from Quebec.
The brain is constantly active and energetically expensive, making up a quarter of the body's energy budget despite occupying only 2% of its mass. To fuel this incessant activity, the brain relies on glucose, which accommodates 99% of its metabolic needs. In most cases, glucose is the ideal fuel since it is in constant surplus owing to 24-hr access to sugar-rich food. However, the brain is metabolically flexible and capable of metabolizing alternative fuels when glucose is scarce, or, decreasing rapidly. For example, during fasting when glucose stores are dwindling, ketone bodies can supplement the brain's metabolic needs. During intense exercise, when glucose stores are being rapidly depleted, lactate - a byproduct of this glucose turnover - similarly acts as an alternative fuel for the brain. In healthy individuals, exploiting this 'brain metabolic flexibility' may be beneficial in protecting the brain from aging. The main question is: Does the brain substrate switch that occurs during fasting and high-intensity exercise underlie the beneficial effects on the brain? Young, healthy participants will fast for 3 days and complete high-intensity cycling exercise, each of which will induce a brain substrate switch. Participants will also be passively infused with ketones (to simulate fasting) and lactate (to simulate high-intensity exercise) in the fed and rested state. In doing so, the investigators will isolate the brain substrate switch from the broader, pluripotent stressors that encompass fasting and exercise. The main outcome variables are the brain biomarkers: brain-derived neurotrophic factor (BDNF) and secreted amyloid beta precursor protein (sAPPA).
The objective of this study is to determine the efficacy of seven different formulations currently marketed and commercially available cosmetic products on skin tone evenness, post-inflammatory hyperpigmentation, and discrete pigmentation in females of Fitzpatrick skin types IV-VI.
