- Brief Summary
This project is proposed to be a three-year project. The purposes of this project are to develop and examine physical activity program, cognitive rehabilitation training, and new life-style (combination of exercise and cognitive) interventions on primary outcomes (cognitive function), and secondary outcomes (physical fitness, QOL and depression) among community-dwelling elderly adults with MCI.
- Detailed Description
Aim. develop and examine physical activity program, cognitive rehabilitation training, and new life-style (combination of exercise and cognitive) interventions on primary outcomes (cognitive function), and secondary outcomes (physical fitness, QOL and depression) among community-dwelling elderly adults with MCI.
Background. Mild cognitive impairment (MCI) is a common clinical syndrome that identifies people at high risk of developing dementia, and the prevalence range from 7.7 to 51.7%. Although treatments for MCI are currently unavailable, preliminary evidence has identified potential neuro-protective effects of exercise program and cognitive rehabilitation, which may lead to improved outcomes. However, the design and delivery of an appropriate program for people with MCI is challenging for having physical, psychological, cognitive, and social barriers.
Design. A prospective randomized control trial. We developed a Physical activity stage-matched intervention (SMI) (1st year), cognitive rehabilitation (2nd year) and New lifestyle program

Group Intervention Description cognitive training group New life-style Consisted of 12 weekly sessions, lasting 60-90 minutes in groups of 5-8 participants, and 3 monthly boost sessions (to review the strategies and practice solving problems as well). The main strategy was to use cognitive rehabilitation strategies to promote generalization in this process to improve memory and behavior. cognitive training group Cognitive training Consisted of 12 weekly sessions, lasting 60-90 minutes in groups of 5-8 participants, and 3 monthly boost sessions (to review the strategies and practice solving problems as well).

To promote incorporating exercising in their daily life routine during the 24-week period, we provided 2 group-based (5-8 participants with 2 instructors at community centers, 60' each) and one home-based (with the exercise program VCD and manual to bring home, 30') exercise program. exercise group New life-style The exercise program will include instructions on how to read the program, complete the activities, record their sessions, and exercise safely at first day.

- Primary Outcome Measures
Name Time Method Taiwan version of Prospectiv and Retrospective Memory Questionaire (PRMQ) 5min There are 11 items and include general memory and prospective memory sections for analysis the type and frequency of memory problem in elders' daily live. Items are posed in likert scale ranges from 1 (never) to 5 (always). The total score may range from 11-55. A higher score indicates a higher level of memory impaired.
Mini-Mental State Examination 8min The participants' cognitive function was assessed by the Mini-Mental State Examination (cut point base for participants' levels of education).
The Alzheimer's Questionnaire 2min Malek-Ahmadi et al., (2012) a 21-item, informant-based dementia assessment designed for ease of use in a primary care setting.
- Secondary Outcome Measures
Name Time Method Depressive symptoms 3min A short-form Geriatric Depression Scale (GDS) that consisted of 15 questions was the primary outcome measure (Sheikh and Yesavage, 1986). Scores of 0-4 are considered normal; 5-8 indicates mild depression; 9-11 indicates moderate depression; and 12-15 indicates severe depression. The Chinese version of the GDS-15 demonstrates high reliability (Liao et al., 2005); in this study, the Cronbach's α is .91.
Mobility 10min The Tinetti Performance-Oriented Mobility Assessment (POMA) is a balance tool that was originally developed for use in the institutionalized, older adult population and contains both a balance and a gait component (Tinetti, 1986). The test comprises 16 items (9 balance-related items and 7 gait-related items), with the highest achievable score being 28 points
Quality of life 8min The SF-36 questionnaire was used to measure quality of life. This 36-item questionnaire assesses health-related functions for eight distinct domains, which can be divided into physical component and mental component scales. Subsequent to summing the Likert-scaled items in the SF-36 survey, scores in each scale are standardized so that they each range from 0 to 100.
