Brief summary
The goal of this clinical trial is to determine the feasibility of a 12-week program of Tai Chi for memory (TCM) among older adults with mild cognitive impairment (MCI) or dementia and to determine the effects of TCM on physical functioning, depression, and health-related QoL. Two experimental groups will be recruited for inclusion criteria of community-residing older adults with a diagnosis of either MCI or Dementia.
Detailed description
The purpose of the study are to determine the acceptability of a 12-week program of Tai Chi for memory (TCM) among older adults with mild cognitive impairment (MCI) or dementia; and to determine the effects of TCM on physical functioning, depression, and health-related QoL. A quasi-experimental design was used with two groups classified according to the level of their cognitive impairment (MCI vs. Dementia). Depression, health-related QoL, and physical functioning including grip strength, balance, flexibility, and mobility were measured before and after the 12-week TCM program. Depression was measured using the Korean version of the Geriatric Depression Scale. Health-related QoL was measured using the 12-item Short Form survey (SF-12). Grip strength was assessed using a digital hand dynamometer. Flexibility was assessed using the standard sit-and-reach test. Balance was measured using the one-leg-standing balance test. Mobility was assessed using the timed up and go test. Paired and independent t-tests will be used to compare the effects of TCM within and between groups.
Interventions
BEHAVIORALTai Chi for memory
The adapted form of TCM will be provided at 60 minutes per session, twice a week for 12 weeks by a certified Tai Chi instructor who had experience in teaching older adults with cognitive impairments.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| physical function-grip strength | changes from pretest to 12 week posttest scores | grip strength by assessed in both hands using a digital hand dynamometer (0-90 kg; Labisen KS-301) |
| physical function - flexibility | changes from pretest to 12 week posttest scores | by the standard sit-and-reach test (SSRT) |
| physical function - balance | changes from pretest to 12 week posttest scores | assessed using a one-leg-standing balance test (OLST) |
| physical function - mobility | changes from pretest to 12 week posttest scores | assessed by the Timed Up and Go test (TUG) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| emotional functioning - depression | changes from pretest to 12 week posttest scores | assessed by the short form of the Korean version of the Geriatric Depression Scale (SGDS-K) with 16 items (yes/no). higher scores indicate more depressive symptoms |
| Short Form Health Survey 12 (SF12) | changes from pretest to 12 week posttest scores | Short Form Health Survey 12, which consists of eight dimensions: general health, physical functioning, role physical, body pain, vitality, social functioning, role emotional, and mental health. two summary scores for the physical and mental components of health-related QoL are calculated by using the weighted means for the eight domains. |
