Dual-task Training for Function in MCI
- Conditions
- Mild Cognitive Impairment
- Interventions
- Behavioral: Dual-Task Training
- Registration Number
- NCT04059705
- Lead Sponsor
- State University of New York at Buffalo
- Brief Summary
Mild cognitive impairment (MCI) is an intermediate stage between the expected cognitive decline of normal aging and severe dementia associated with Alzheimer's disease (AD). In the United States about 20% of older adults have MCI. Loss of cognitive function in aging can have far-reaching and devastating impacts on functional status, independence, and quality of life. Unfortunately, the therapeutic options to slow progression of cognitive decline in aging are limited. Dual-task training; that which involves simultaneous cognitive and motor challenges, is a high-impact potential therapy to slow progressive loss of both motor and cognitive function in aging. The purpose of this trial is to examine the feasibility and therapeutic impact of a novel dual-task physical activity intervention on executive and motor functions among adults, 65 years or older, who have MCI. the investigative team anticipates that findings from this trial will inform development of larger community-based studies focused on improving function and ability to maintain independence in older age.
- Detailed Description
Mild cognitive impairment (MCI) is an intermediate stage between the expected cognitive decline of normal aging and severe dementia associated with Alzheimer's disease (AD). In the United States about 20% of older adults have MCI, and approximately 15% per year of those with MCI will progress to AD. With our rapidly aging society, we are approaching a public health crisis for which we are not fully prepared. Impaired cognitive function in aging can have far-reaching and devastating impacts on functional status, ability to maintain independence, and overall quality of life. Unfortunately, the therapeutic options to slow progression of cognitive decline in aging are limited.
Dual-task training that involves simultaneous cognitive and motor challenges improves certain domains of both cognitive and motor function in older adults with MCI. However, we do not yet know the optimal methods of delivering this high-impact potential therapy in community-based settings with unique limitations and strengths. Therefore, the aims are to; 1) test the feasibility of conducting a community-based dual-task (thinking while exercising) physical activity intervention among adults, 65 years or older, with MCI; and 2) examine the impact of dual-task training on attention and motor function among adults, 65 years or older, with MCI.
To accomplish these aims the investigators will conduct an 12-week, dual-task training program using the SmartFit Multisensory Fitness System (Oxnard, CA) among older adults with MCI. Our group-based training program involves two 1-hour training sessions per week, designed to simultaneously engage the mind and body, while promoting self-efficacy. Attention and motor function will be assessed prospectively.
The investigators anticipate that findings from this trial will inform development of methods to bring evidence-based, non-invasive therapies into communities in need, in order to preserve function, independence, and quality of life well into older age.

Study & Design

- INTERVENTIONAL
- Study Design
- SINGLE_GROUP
- Arm && Interventions
Group Intervention Description Dual-Task Intervention Dual-Task Training This study arm will receive the dual-task training program.
- Primary Outcome Measures
Name Time Method Change in Motor Function from baseline to 12 weeks baseline, week 6, week 12 Change in motor function will be assessed prospectively using the Short Physical Performance Battery.
Change in Attention from baseline to 12 weeks baseline, week 6, week 12 Attention will be assessed prospectively using the Stroop Task and Trail-making Test.
- Secondary Outcome Measures
Name Time Method Change in Exercise Self Efficacy from baseline to 12 weeks baseline, week 12 Self efficacy for exercise will be assessed using the Self Efficacy for Exercise Scale. Total score is derived by summing the individual scores for each question. Scoring range for this instrument is 0 - 90 points with higher scores representing better outcomes.
Outcome Expectations for Exercise from baseline to 12 weeks baseline, week 12 Outcome Expectations for exercise will be assessed using the Outcome Expectations for Exercise Scale. This instrument has 9 total items. Total score is derived by summing the responses to these items and dividing by the number of responses. Scoring is out of 9 points, with higher scores demonstrating higher outcomes expectations.
