An observational study in Stroke, Motor İmagery Ability and Mental Chronometry, sponsored by Medipol University. Completed at 1 site in Turkey. Open to participants aged 40 Years to 80 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2021-12-10.
Sponsored by Medipol University · Observational
It was aimed to determine the relationship between post-stroke imagination ability, balance, and functionality, and to compare the motor imagery skills of those who had stroke with compatible healthy individuals.
İn the study, 20 individuals with hemiplegic or chronic hemiparesis who agreed to participate by signing the voluntary consent form, who meet the inclusion criteria, and 20 healthy individuals who are similar in terms of age, gender and education level will be included.
The individuals included in the study will be divided into two groups:
Group 1: Stroke Patients Group 2: Control Group
7,286 studies on the registry are indexed under Stroke; 2,007 are open to participants now.
This study's enrollment of 40 is below the median of 160 across 1,692 observational studies indexed under Stroke.
Browse Stroke studies →Medipol University is the lead sponsor of 311 studies on the registry; 86 are open to participants now.
Counted across the registry records on this site, refreshed daily.
In this study, we will enroll patients based on the statistics of the articles titled "Motor imagery in stroke patients or plegic patients with spinal cord or peripheral diseases" and "Effects of a single mental chronometry training session in subacute stroke patients - a randomized controlled trial". We calculated the power analysis from this article. According to this calculated; α=0.05, 1-β=0.90, effect size=0.96.
Stroke patients treated at Istanbul Medipol University Pendik Hospital Physical Medicine and Rehabilitation Clinic Neurology Rehabilitation Unit and healthy individuals matching them will be included.

Fugl - Meyer Motor Recovery Assessment Form
It will only be evaluated in the stroke group. It is a scale that evaluates sensorimotor recovery after stroke. Each parameter was scored as 0 points: unsuccessful, 1 point: partially successful, 2 points: completely successful performance on the scale, which includes 50 items specific to stroke and based on performance. The maximum score that can be taken for the upper extremity in the scale where voluntary movement, reflex activity, grip, coordination and speed are evaluated is 66 and 34 for the lower extremity.
Time frame: Day 0
Mini-Mental State Test
It was used to determine the cognitive state. The Mini-Mental State Test was first published by Folstein et al. It consists of eleven items under 5 main headings: orientation, record memory, attention and calculation, recall and language, and the total score is evaluated over 30 points. The ideal threshold value of the Mini-Mental State Test was found to be 24.
Time frame: Day 0
Clock Drawing Test
It will be used to assess the phenomenon of neglect of the stroke individual. The individual is asked to draw a clock circle and insert the numbers of the clock into it. After finishing the numbers, the hands of the clock are placed to show 11 to 10 past.
Time frame: Day 0
Digit Span Test
This test to evaluate the ability to sustain attention is a subtest of the Wechsler Adult Intelligence Scale--Revised battery. The test consists of two parts as forward and reverse range. In both parts, random numbers are read to the person at one second intervals, the numbers increase with each attempt and the person is asked to repeat in the same way. In both episodes, the number of digits of the previous sequence in which the person failed twice in a row constitutes the range. The maximum score that can be obtained for each section is 7, and a total of 14 points for the whole test.
Time frame: Day 0
Kinesthetic and Visual Imaging Questionnaire
The Kinesthetic and Visual Imaging Questionnaire has been developed to evaluate the imagination ability in individuals with physical disabilities. The purpose of the questionnaire is to determine to what extent individuals visualize and feel the movements they imagine.
Time frame: Day 0
Box and Block Test
It is a highly sensitive test for changes in upper extremity functional performance. However, this study will be used for evaluating mental chronometry ability rather than functional performance.
Time frame: Day 0
Functional Independence Scale
It is a scale used to evaluate the motor and cognitive competence of patients in daily life activities. Scale; It consists of 18 items that evaluate six functions: self-care, sphincter control, transfer, displacement, communication, and social perception. Each item is scored between 1 (activity fully dependent) and 7 (activity fully independent) in proportion to the amount of assistance received. A minimum of 18 and a maximum of 126 points can be obtained. A low score means that the level of addiction has increased.
Time frame: Day 0
Berg Balance Scale
It is a 14-item scale that evaluates the tasks used in daily life activities.Standing up without support, standing without support, sitting without support, standing up, transfers, standing with feet, standing with legs while standing, reaching out while standing, picking up from the ground, looking back, 360 degree rotation, firm side standing on the stool, one foot standstill and standstill functions are evaluated.Each item is planned between 0-4; 0 is unable to fulfill the task, 4 is to fulfill the task successfully. The total score of the test is between 0-56.0-20 points: wheelchair dependent, 21-40: assisted walking, 41-56: means independent ambulation.
Time frame: Day 0
Time Up and Go Test
The test measures the speed during many functional maneuvers such as standing up, walking, turning, and sitting. In the test, the person is asked to stand up from the chair, walk 3 meters (10 feet) at a safe and normal pace, turn, walk back and sit on the chair, and the time is recorded in seconds. A short performance period indicates a good balance performance.
Time frame: Day 0
Functional Reach Test
Subjects will asked to stand comfortably, to make a fist, and to raise their arm until it was parallel to the yardstick (position 1). The placement of the end of the third metacarpal along the yardstick will recorded. Subjects will then asked to reach as far forward as they could without losing their balance (position 2), and the position of the end of the third metacarpal along the yardstick will again recorded. No attempt will make to control the subject's method of reach, but if he will touch the wall or took a step during the maneuver, that trial will consider invalid and repeated.
Time frame: Day 0
Hand Lateralization Test
It requires participants to question the laterality of the hand images presented and is commonly used to measure motor imagination ability in humans. It is used to evaluate implicit motor imagination ability. It is also a test that evaluates mental rotation, another dimension of imagination.
