Motor Signature, Falls Risk, and Home-Based Interventions in Older Adults With Mild Cognitive Impairment

Not Applicable

• Conditions: Mild Cognitive Impairment; Fall

• Registration Number: NCT03839576
• Lead Sponsor: Taipei Medical University

Brief Summary

A single-blinded, randomized controlled trial is designed to compare the effects of social interaction, computerized cognitive training, lower extremity strengthening, and tai chi chuan on improving cognitive functions and gait/mobility and reducing falls among 228 subjects with mild cognitive impairment, in which the influence of adherence to the intervention programs will also be examined.

Primary Outcome Measures

Name	Time	Method
Mattis Dementia Rating Scale (MDRS)	12 months	The Mattis Dementia Rating Scale (MDRS) contains five cognitive domains of attention, initiation/perseveration, construction, conceptualization, and memory, which specifically assess concentration, verbal fluency, visuospatial skills, analogical reasoning, and short-term memory, with score ranges for these domains of 0\~37, 0\~37, 0\~6, 0\~39, and 0\~25 points, respectively, and a total score range of 0\~144 points.
balance	12 months	The Tinetti balance score ranges 0\~26, with a higher score indicating a better balance ability.
falls	12 months	number of falls and multiple falls
mobility	12 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.
modified Telephone Interview of Cognitive Status (TICS-M)	12 months	The modified Telephone Interview of Cognitive Status (TICS-M) consists of the date of the interview, age, phone number, immediate and delayed word list recall, counting backward, responsive naming, word opposites, and repetition, with a total score range of 0\~50.

Secondary Outcome Measures

Name	Time	Method
fear of falling	12 months	Activities-specific Balance Confidence (ABC) scale assesses an individual's confidence in performing 16 common daily tasks without losing balance, and total scores of the ABC scale are determined by the accumulated average of each item score and range between 0 and 100, with lower scores indicating greater balance confidence.
depressive symptoms	12 months	Depressive symptoms will be assessed using the 15-item Geriatric Depression Scale.
activity of daily living (ADL)	12 months	The activity of daily living (ADL) scale consists of seven basic ADLs (self-feeding, self-dressing, grooming, walking, getting in/out of bed, bathing, and controlling the bladder) and seven instrumental ADLs (using a telephone, transporting oneself, shopping, preparing meals, doing housework, taking medication, and managing one's money). These items are graded as 0 points (inability), 1 point (needs some help), or 2 points (no help needed). The ADL score ranges from 0 to 28 points, with a lower score indicating greater activity disability.
