Behavioral: Exercise
Registration Number
NCT03839563
Lead Sponsor
Taipei Medical University
Brief Summary

The effectiveness of conventional exercise, tai chi chuan and health education/usual physical activity over a 6-month intervention period in improving primary outcomes and secondary outcomes in older mild cognitive impairment adults will be compared. Third, whether changes in serum levels of the brain-derived neurotrophic factor (BDNF), insulin-like growth factor (IGF)-1, and vascular endothelial growth factor (VEGF) and expression of the apolipoprotein E (APOE) ε4 allele parallel changes in gait characteristics and cognitive functions after the intervention will be examined.

GroupInterventionDescription
Tai chi chuanExerciseThe 8-form Yang-style tai chi chuan intervention will take place at a subject's residence or in the neighborhood once a week for 6 months, and each session will last 60 min.
Conventional exerciseExerciseThis exercise will comprise stretching, muscle strengthening, and balance training at increasing difficulty levels, tailored and supervised by a physical therapist, and will take place at a subject's residence or in the neighborhood once a week for 6 months. Each session will last 60 min.
Primary Outcome Measures
NameTimeMethod
Serum levels of IGF-112 months

Serum IGF-1 concentrations will be assessed.

Serum levels of BDNF12 months

Serum BDNF concentrations will be assessed.

Serum levels of VEGF12 months

Serum VEGF concentrations will be assessed.

Gait characteristics12 months

Performance on six gait characteristics (velocity, cadence, stride length, swing time, stride length variability, and swing time variability) will be measured with a 6-m electronic walkway of GAITRite.

Global cognition12 months

Global cognition will be assessed using the Mini-Mental State Examination (MMSE). The MMSE comprises 11 questions, and the score ranges 0\~30, with lower scores indicating poorer global cognition.

Secondary Outcome Measures
NameTimeMethod
Falls12 months

number of falls and multiple falls

Fear of falling12 months

Fear of falling will be assessed using the Falls Efficacy Scale (FES) test.

Mobility12 months

The timed up and go test requires subjects to rise from a standard chair, walk a distance of 3 m, turn, walk back to the chair, and sit down. The time to complete the timed up and go will be recorded.

Muscle strength12 months

Grip strength will be assessed via a handgrip dynamometer and measured in kilograms of isometric force.

Tinetti balance12 months

The Tinetti balance score ranges 0\~26, with a higher score indicating a better balance ability.

Depressive symptoms12 months

Depressive symptoms will be assessed using the 15-item Geriatric Depression Scale (GDS).
