About this study

Official title: The Effects and Mechanism of the Sequential Combination of Exercise and Cognitive Training on Cognitive Function in Stroke Patients With Cognitive Decline: A Randomized Controlled Trial

The purpose of this study is to determine the treatment effects of sequential combination of aerobic exercise and cognitive training on cognitive function, physiological markers, daily function, physical function, social participation and quality of life in stroke patients with cognitive decline.

Read the detailed description

Cognitive decline after stroke is a common sequela and is highly associated with functional disability. Empirical evidence shows that exercise combined cognitive training may induce neuroplastic changes that modulate cognitive function. However, evidence about the effects of combined exercise-cognitive trainings on physiological biomarkers, cognitive and physical functions in stroke patients with cognitive decline is still less. The present study aim to investigate the effects of sequential combination of exercise-cognitive trainings on cognitive, physical, and daily function. In addition, the physiological mechanism of the combination training on cognitive function by several biomarkers including the brain-derived neurotrophic factor (BDNF), antioxidative marker, HbA1c, and plasma lipid level will be investigated. This study is a single-blind randomized controlled trial. Participants will be randomly assigned to SEQ group in which sequentially perform physical exercise and cognitive training or to CI group of control intervention.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • aerobic exercise trainingBehavioural

    The aerobic exercise program using progressive resistive stationary bicycle training which will contain warm-up, resistive physical exercise, and cool-down. The training resistance will increase with improvement of participants' performance.

  • control trainingBehavioural

    The control training program will receive 30 minutes non-aerobic exercise training, including stretching muscle skills, joint mobility exercises; in addition to one 30-minute session of unstructured mental activities, such as reading books or reading educational films.

  • cognitive trainingBehavioural

    The computerized cognitive training program will be implemented with the brainHQ to target abilities of visuospatial processing, attention, memory, and executive function. The level of the training program will become more difficult with progress in participants' targeted cognitive abilities.

Study groups in NCT03045991
Study groupRoleWhat they receive
sequential training group (SEQ)ExperimentalThe sequential training group (SEQ) will first receive 30-minutes aerobic exercise training followed by 30-minutes computerized cognitive training. All participants will receive a training session for 60 minutes per day, three days per week for 12 weeks, a total of 36 training sessions. Before and after the treatment, a total of 2 evaluations were conducted, including clinical assessments and blood test (each 18c.c.). A saliva sample (2 mL) will only be collected once from each subject. A follow-up assessment of clinical outcomes will be conducted at six month after the end of the course of treatment.

  5. Change scores of Functional Independence Measure (FIM)

    The FIM assesses the dependence level of individuals with stroke to perform 18 activities (13 motor and five cognitive tasks) in daily living. The score ranges from 18 to 126 and higher scores demonstrate greater independent participation in daily activities.

    The UE-FMA subscale will be used to assess the sensorimotor impairment level of UE in patients after stroke. The UE-FMA contains 33 movements with a score range from 0 to 66. A higher UE-FMA score indicates less impairment of the paretic limb. The validity and reliability of FMA is good to excellent.

    We will evaluate isometric knee flexors and extensors muscle strength using handheld dynamometer. Also, we will use hand dynamometer to measure grip strength of the affected and less affected hand while the participant is seated, with the elbow at 90-degree flexion. We will record the mean value of 3 attempts.

  20. Change scores of Actigraphy

    In addition to MAL, the ActiGraph GX3 accelerometers (ActiGraph, Shalimar, FL, USA) will be used to quantitatively assess the amount of arm use in the participants' home settings.The actigraphy will be placed on bilateral wrist for 3 consecutive days before and after the 1-month intervention. The participants will carry the actigraphy all day except for activities that involve water, such as swimming or bathing. Using the actigraphy, investigators will be able to record and calculate the number of hand movements per minute, and the data will be analyzed with the MAHUFFE software (http://www.mrc-epid.cam.ac.uk/). The actigraphy has often been used to evaluate arm use in patients with stroke.

    Measured: Baseline, posttest (an expected average of 3 months)

  21. Change scores of Mini-Mental State Exam (MMSE)

    The Mini-Mental State Examination (MMSE) is the most commonly administered psychometric screening assessment of cognitive functioning. The MMSE is used to screen patients for cognitive impairment, track changes in cognitive functioning over time, and often to assess the effects of therapeutic agents on cognitive function. The total score of MMSE ranged from 0 to 30. Higher values represent a better cognitive functioning.

    Measured: Baseline, posttest (an expected average of 3 months), follow-up (up to 9 months)

  22. Change scores of Medical Research Council scale (MRC)

    The MRC is an ordinal scale that assesses muscle strength. The scoring for each muscle ranges from 0 to 5, with a higher score indicates stronger muscle. The reliability of MRC for all muscle groups was good to excellent in patients with stroke.

    Measured: Baseline, posttest (an expected average of 3 months), follow-up (up to 9 months)

  23. Change scores of National Institutes of Health Stroke Scale

    The National Institutes of Health Stroke Scale, or NIH Stroke Scale (NIHSS) is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke. The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0.

    Measured: Baseline, posttest (an expected average of 3 months), follow-up (up to 9 months)
