Physical Health and Function

Through the Marcus Institute’s research we are learning how older adults can maintain independence and quality of life.
 

Research About Maintaining Physical Function as We Age

Mobility is the most common disability among older Americans. More than 40 percent of older adults ages 65-79 have at least one disability in either self-care, household activity, or mobility. For those 80 years and older, this share rises to more than 70 percent. 

Moreover, 10 percent of older adults in the community and up to 50 percent in nursing homes have frailty, which is a state of increased vulnerability resulting from a decline in function across multiple systems of the body. The "oldest old" are especially at risk of developing the condition. 

Maintaining physical function as we age is key to living independently and continuing the lifestyle and activities that bring us meaning and joy. 

The Marcus Institute's research into the physical health and function of older adults focuses in six main areas: 

  • Mobility
  • Nutrition
  • Arthritis
  • Frailty
  • Osteoporosis
  • Falls

Marcus Institute Research About Maintaining Mobility and Preventing Frailty in Older Adults

The Marcus Institute's research programs are dedicated to uncovering how physical health and function of older adults impacts their quality of life, and discovering interventions to maintain physical health and function. 

Marcus Institute researchers are: 

  • Investigating innovative methods to measure and apply frailty in various clinical and research settings
  • Examining the prevalence, causes, and prevention of frailty
  • Studying the prevention and treatment of musculoskeletal disorders including fractures, osteoporosis, osteoarthritis, sarcopenia and hyperkyphosis
  • Examining the role of diet and nutrition in bone and muscle health and frailty
  • Conducting ground-breaking research in the use of non-invasive brain stimulation to improve mobility and balance and reduce falls among older adults

NFLPA/Harvard Accelerated Research Collaboration to Protect and Improve the Health of Football Players

The project will implement kinematic assessments of gait and balance into the Harvard Football Players Health Study (FPHS) in-person assessments of retired professional American-style football players. The scientific aim of this study is to determine the effects of long-term exposure to this sport on health outcomes in later life.

NIA AD/ADRD Health Care Systems Research Collaboratory (IMPACT)

The NIA AD/ADRD Collaboratory will provide the national infrastructure necessary to catalyze and support embedded pragmatic clinical trials of non-pharmacological interventions for persons with dementia. By convening national experts to provide consultation and guidance to Collaboratory-funded pilot projects and NIA-funded trials, the Collaboratory has the potential to transform care delivery, quality, and outcomes for millions of Americans suffering with AD/ADRD.
