Purpose of the study: Falls in Alzheimer's Disease (AD) are common and lead to fractures, acute hospitalizations and increased rate of institutionalization. Poor balance and gait abnormalities, commonly associated with AD, are risk factors for falls. Improving balance and gait abnormalities is critical to prevent falls in AD.
Exercise interventions improve gait and balance in elderly. Walking is the most commonly recommended home-based exercise program for elderly by primary care providers. However, it is difficult to engage patients with AD in long term exercise programs. Barriers to exercise programs include lack of motivation, poor engagement, and external factors such as the cost of physical therapy (PT). Use of readily available technology might bridge this gap by providing high level of engagement via use of multimedia at an affordable price.
Wii-Fit is a Nintendo gaming console used for aerobics, strength training, and balance activities. This device includes a balance board that senses weight, movement and balance. Wii-Fit is a TV based self-directed activity not limited by the constraint of a therapist's presence. Virtual trainers talk the user through the activity while tracking progress. Furthermore, visual and auditory feedback improves engagement. Some skilled nursing facilities have started using the Wii-Fit as an adjunct to PT, and note improvement in balance along with social benefits but no systematic studies are done to generalize the findings.
The investigators propose an 8 week prospective randomized study with the treatment group receiving the exercise program delivered by Wii-Fit system and the comparison arm receiving a walking exercise program.

For some patients with mobility issues, a walking frame (commonly known as a zimmer frame - trademark of Zimmer Holdings), is provided to keep them on their feet and help them remain more ...
The purpose of this study is to determine whether the comprehensive multidisciplinary intervention (geriatrician, physical therapist and occupational therapist falls risk assessment and in...
This is a randomized trial of 2 nursing home staff educational approaches to reduce falls in VA nursing home (CLC) residents. One is a traditional falls education program using web-based ...
Stroke is the leading cause of severe disability in adults. The first cause of alterations in the quality of life and autonomy in these patients are disorders of walking and the balance. T...
Background: Dynamic balance keeps the vertical projection of the center of mass within the base of support while the center of mass moves. The age-related decrease in dynamic balance is a ...
Older adults are at an exceptionally high risk of falls, and most falls occur during locomotor activities such as walking. Reduced local dynamic stability in old age is often interpreted to suggest a ...
Falls are a major cause of morbidity among older people. Multifaceted interventions may be effective in preventing falls and related fractures.
Most falls among older adults occur while walking. Pelvic and trunk motions are required to maintain stability during walking. We aimed to explore whether training that incorporates unexpected loss of...
Walking instability is a contributor to falls and other undesired changes in walking performance. We investigated the effect of split-belt treadmill based perturbations on dynamic stability. Furthermo...
Falls are the top one type in all unintentional injuries. In this study, we aim to explore the epidemiological characteristics of falls and assess the intervention effect. Our research had interviewed...
An activity in which the body advances at a slow to moderate pace by moving the feet in a coordinated fashion. This includes recreational walking, walking for fitness, and competitive race-walking.
Falls due to slipping or tripping which result in injury.
The rate at which steps are made while walking.
A study in which observations are made before and after an intervention, both in a group that receives the intervention and in a control group that does not.
A study that uses observations at multiple time points before and after an intervention (the "interruption"), in an attempt to detect whether the intervention has had an effect significantly greater than any underlying trend over time.
Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous mat...
