The loss of mobility during aging impacts independence and leads to further disability, morbidity, and reduced life expectancy. The study objective was to examine the feasibility and safety of conducting a randomized controlled trial of yoga for older adults at risk for mobility limitations. The investigators hypothesized that sedentary older adults could be recruited for the study, would attend either yoga or a health education control, would complete assessments, and that the interventions could be safely delivered.

Importance: Aging is characterized by numerous molecular, physiological, functional, motor and psychological changes, such as loss of postural balance and reduced muscle mass/strength. Such modifications often lead to reduced physical-functional capacity in the elderly and increased risk of falls. Currently, physical exercise is widely used to improve physical performance and reduce, at least in part, postural instabilities and the risk of falls. In this context, the Pilates method may be a good strategy to improve body balance, muscle strength and, potentially, the perception of quality of life in this population, depending how the exercises are performed. This study seeks to assess whether practicing Pilates exercises in orthostatic position results in differential effects on walking mobility and postural balance in healthy elderly women when compared to the standard sequence in the Pilates method, which involves less time performing exercise in the orthostatic position. The study hypothesis is that a higher relative volume of Pilates exercises performed in the orthostatic position can promote greater benefits in terms of walking mobility and postural balance compared to the standard Pilates protocol in the elderly.
Frailty in older adults is a consequence of physical inactivity, which leads to poor physical function, disability and poor health outcomes. Nearly 60% of older adults report inactivity. Emotion regulation strategies have affective, cognitive and social consequences. Positive emotions are significantly associated with a higher ability to perform activities of daily living. There is a gap in the understanding of how exercise influences the selection of emotion regulation strategies (avoidant vs. adaptive) in frail older adults. The investigators propose to examine the interactions between regular exercise, selection of emotional regulation strategies, and daily physical activity in frail sedentary older adults.
This study will be conducted to determine the safety and feasibility of translating a physical activity intervention (LIFE Study) into a community setting. Study outcomes include physical performance, safety, and feasibility of conducting the LIFE PA intervention in a community setting.
Approximately 30% of community-dwelling older adults experience one or more falls per year, resulting in injuries, loss of independence, and reduced quality of life. While there are known physiological risk factors for falls, including poor balance and altered gait patterns, it is now recognized that impaired cognitive functioning is also a risk factor for falls. Within the broad construct of cognition, one specific domain that has been focused on in the falls literature is attention. The literature suggests that improving attention in those at-risk for falls may reduce older adult's risk of falling.
The Validity and Reliability of a Wearable System for Assessing Turning Characteristics.
The aging population is at an exceptionally high risk of debilitating falls, contributing significantly to reduced independence and quality of life. It remains extremely challenging to screen for falls risk, and programs designed to mitigate falls risk have only modestly influenced the sizeable portion of the aging population experiencing one or more falls annually. Balance control in standing and walking depends on integrating reliable sensory feedback and on planning and executing appropriate motor responses. Walking balance control is especially dynamic, requiring active and coordinated adjustments in posture (i.e., trunk stabilization) and foot placement from step to step. Accordingly, using a custom, immersive virtual environment, the investigators have shown that sensory (i.e., optical flow) perturbations, especially when applied during walking, elicit strong and persistent motor responses to preserve balance. Exciting pilot data suggest that these motor responses are remarkably more prevalent in old age, presumably governed by an increased reliance on vision for balance control. Additional pilot data suggest that prolonged exposure to these perturbations may effectively condition successful balance control strategies. Founded on these recent discoveries, and leveraging the increase reliance on vision for balance control in old age, the investigators stand at the forefront of a potentially transformative new approach for more effectively identifying and mitigating age-related falls risk. The investigator's overarching hypothesis is that optical flow perturbations, particularly when applied during walking, can effectively identify balance deficits due to aging and falls history and can subsequently condition the neuromechanics of successful balance control via training.
Greater trochanteric pain syndrome (GTPS) is characterized by pain over the greater trochanter, which can refer down the lateral aspect of the hip. Historically, conservative treatments such as rest/activity modification, anti-inflammatory medication, physiotherapy and local corticosteroid injection, are employed as first-line management, with some refractory cases requiring surgical intervention. Acknowledging the unpredictable response and frequent recurrences associated with traditional non operative treatment, the risks and prolonged rehabilitation associated with surgery, and the favorable results from prior studies involving radial pressure waves as a treatment for GTPS, the aim of this study is to investigate the dose-related effect of focalized shockwave treatment at different total energy influx in patients with chronic GTPS.
