The Therapeutic Effect of Exercise Training on Old Patients With Dementia and Mild Cognitive Impairment: A Randomized Controlled Trial

This study aimed to clarify whether strength training or aerobic training could bring more benefits for patients with dementia, another study is to clarify whether isokinetic or isotonic training could bring more benefits for patients with mild cognitive impairment

Study Overview

Detailed Description

Exercise training has been evidenced to bring various of benefits for patients with dementia in past studies. However, whether strength training or aerobic training could bring better benefits has not been confirmed in the past. This study designed to recruit 30 patients with mild dementia in the first year. Every patient will receive strength training using dumbbells, butterfly machine and vertical leg press machine for four weeks. Outcome measures including self care ability, cognitive function, MCP-1, BDNF and IGF-1 levels, and the degree of depression will be recorded before and after the training. In the second year, the investigators also designed to recruit 31 patients with mild dementia. These participants will instead receive aerobic training using stationary bicycle for four weeks. The same outcome measures will be tested as in the first year. The other part of the study recruited 46 patients with mild cognitive impairment, who were randomized into either a four-week isokinetic or isotonic training program. All cases were evaluated by isokinetic peak torque, 36-item Short Form Survey (SF-36), Mini-Mental State Examination (MMSE), Barthel Index, geriatric depression scale (GDS-15), and Timed Up and Go test (TUG test) before and after each kind of training.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Strength training
Muscle strength training programs
Using dumbbells, butterfly machine and vertical leg press machine for strength training, 12 repetition maximum weight for 12 repetition, three times a day, five days a week, for a total of four weeks
Experimental: Aerobic training
Aerobic training programs
Using stationary bicycle to perform cardiopulmonary endurance training in 50-70 heart rate reserve for 20 minutes, five days per week, for a total of four weeks
Experimental: Isokinetic training
Using Biodex isokinetic dynanometer and set it in isokinetic mode in 60 degree per second
Experimental: Isotonic training
Using Biodex isokinetic dynanometer and set it in isotonic mode at 60% of the maximal peak torque

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Barthel index
Time Frame: 4 weeks
To evaluate function of activities of daily living, range from 0-100, higher values represent a better outcome
4 weeks
Mini-mental state examination
Time Frame: 4 weeks
To evaluate cognitive function, range from 0-30, higher values represent a better outcome
4 weeks
Montreal Cognitive Assessment
Time Frame: 4 weeks
To evaluate cognitive function, range from 0-30, higher values represent a better outcome
4 weeks
Geriatric Depression Scale
Time Frame: 4 weeks
To evaluate patient's depression status, range from 0-15, higher values represent a worse outcome
4 weeks
Timed up and go test
Time Frame: 4 weeks
Measure the time taken by a patient to stand up from a chair, walk three meters, return, and sit back on the chair
4 weeks
SF-36
Time Frame: 4 weeks
consists of 36 questions categorized into 8 subdomains, including physical functioning, role limitations due to physical health, pain, general health condition, vitality, social functioning, role limitations due to emotional problems, and emotional well-being.
4 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Concentration of serum brain derived neurotrophic factor (BDNF)
Time Frame: 4 weeks
Increasing BDNF level is related to preventing neurodegeneration.
4 weeks
Concentration of plasma insulin-like growth factor-1 (IGF-1)
Time Frame: 4 weeks
Lower plasma level of IGF-1 is associated with an increased risk of developing Alzheimer's dementia, and higher levels of it may protect against neurodegeneration.
4 weeks
Concentration of plasmamonocyte chemotactic protein-1 (MCP-1)
Time Frame: 4 weeks
The elevation of MCP-1 concentration usually means the progression of systemic inflammation.
4 weeks
