About this study
Official title: Physical Exercise to Prevent Disability Pilot Study
The purpose of this study is to gather preliminary data that will determine the feasibility of conducting a Phase III, randomized, controlled trial (RCT) that will provide definite evidence in the use of physical exercise to prevent mobility disability in older persons.
Read the detailed description
As the life expectancy of older Americans increases, prevention of age-associated physical function decline and disabilities has emerged as a major clinical and public health priority. A critical factor in an older person's ability to function independently is mobility, the ability to move without assistance. Older people who lose mobility are less likely to remain in the community, have higher rates of morbidity, mortality, and hospitalizations and experience a poorer quality of life. While several studies suggest that physical activity may prevent physical disability, including mobility disability in both healthy and frail older adults, definitive evidence is lacking. A Phase 3, randomized, controlled trial is needed to fill this evidence gap. Currently data to estimate sample size needs for such a trial are insufficient and further feasibility data should be gathered before such a trial can be effectively designed and implemented.
To refine key trial design benchmarks (including sample size calculations to demonstrate the feasibility of a full-scale trial and refining/developing recruitment, procedures, materials and organizational infrastructure), the LIFE (Lifestyle Interventions for Independence in Elders) study conducts a pilot, single-blind, randomized, controlled trial involving comparison of a physical activity program of moderate intensity to a successful aging program. Approximately 400 sedentary persons aged 70 to <90 years who are at risk of disability are followed for at least one year at four intervention sites: Wake Forest University School of Medicine in Winston Salem, NC; the University of Pittsburgh in Pittsburgh, PA; the Cooper Institute in Dallas, TX; and the Stanford University in Palo Alto, CA. The Administrative Coordinating Center and the Data Management and Quality Control Center are at Wake Forest University School of Medicine.
The LIFE study assesses the combined outcome of major mobility disability, defined as the incapacity to walk 400 meters (m), or death, which will be the primary outcome of the full-scale study. This outcome has not been used in previous randomized, controlled trials, and therefore, a pilot study is needed to assess its incidence rate. Secondary outcomes include ADL disability, major fall injuries and cardiovascular events. LIFE explores the effects of the intervention on physical performance measures, cognitive function, health-related quality of life, and use of health care services. In addition, LIFE explores and performs cost-effectiveness analyses of the intervention.
This pilot study will yield the necessary preliminary data to design a definitive Phase 3, randomized, controlled trial. By providing a conclusive answer regarding whether physical activity is effective for preventing major mobility disability or death, the results of the full-scale trial will have relevant clinical and public health implications, and will fill an important gap in knowledge for practicing evidence-based geriatric medicine.

As the life expectancy of older Americans increases, prevention of age-associated physical function decline and disabilities has emerged as a major clinical and public health priority. A critical factor in an older person's ability to function independently is mobility, the ability to move without assistance. Older people who lose mobility are less likely to remain in the community, have higher rates of morbidity, mortality, and hospitalizations and experience a poorer quality of life. While several studies suggest that physical activity may prevent physical disability, including mobility disability in both healthy and frail older adults, definitive evidence is lacking. A Phase 3, randomized, controlled trial is needed to fill this evidence gap. Currently data to estimate sample size needs for such a trial are insufficient and further feasibility data should be gathered before such a trial can be effectively designed and implemented.
To refine key trial design benchmarks (including sample size calculations to demonstrate the feasibility of a full-scale trial and refining/developing recruitment, procedures, materials and organizational infrastructure), the LIFE (Lifestyle Interventions for Independence in Elders) study conducts a pilot, single-blind, randomized, controlled trial involving comparison of a physical activity program of moderate intensity to a successful aging program. Approximately 400 sedentary persons aged 70 to <90 years who are at risk of disability are followed for at least one year at four intervention sites: Wake Forest University School of Medicine in Winston Salem, NC; the University of Pittsburgh in Pittsburgh, PA; the Cooper Institute in Dallas, TX; and the Stanford University in Palo Alto, CA. The Administrative Coordinating Center and the Data Management and Quality Control Center are at Wake Forest University School of Medicine.
The LIFE study assesses the combined outcome of major mobility disability, defined as the incapacity to walk 400 meters (m), or death, which will be the primary outcome of the full-scale study. This outcome has not been used in previous randomized, controlled trials, and therefore, a pilot study is needed to assess its incidence rate. Secondary outcomes include ADL disability, major fall injuries and cardiovascular events. LIFE explores the effects of the intervention on physical performance measures, cognitive function, health-related quality of life, and use of health care services.

By providing a conclusive answer regarding whether physical activity is effective for preventing major mobility disability or death, the results of the full-scale trial will have relevant clinical and public health implications, and will fill an important gap in knowledge for practicing evidence-based geriatric medicine.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Physical Activity in people with Physically Challenged and Aging, run by National Institute on Aging (NIA) at 4 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 25 Mar 2010. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Combined outcome of ability to walk 400 m without the use of an assistive device or adjudicated evidence of inability to walk 400 m or death. The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00116194, which also lists 14 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Mar 2010.
