The purpose of this study is to investigate the effect of the whole body vibration exercise on cortical activity and gait function in patients with chronic stroke.
Whole body vibration exercise can provide proper somatosensory stimulation and improve muscle strength and postural control in stroke patients. However, there has not yet been a report on the cortical activity changes induced by whole body vibration exercise. Patients will be randomly assigned to one of the two groups. One group will go through whole body vibration with exercise and the other will only perform exercise. The primary outcome measurement of this study was cerebral cortex activity based on changes in oxygenated hemoglobin concentration using functional near-infrared spectroscopy. Behavioral assessments were performed before and after the intervention session using the 10-meter walk test, timed up and go test, Fugl-Meyer Assessment, and Tinetti Performance Oriented Mobility Assessment.

whole body vibration exercise is a stimulus that uses vibrations generated on a machine with oscillatory movement determined by the amplitude and frequency of the vibration.
maintain a half-squat position (knee joint angle at 160 degrees) on the tilt table with an incline of 60 degrees
Cerebral cortex activity
cerebral cortex activity was measured based on changes in oxygenated hemoglobin concentration using fNIRS
Time frame: check before, during and directly after intervention(for approximately 14 minutes)
10 meter walk test
performance measure used to assess walking speed in metres per second over a short distance. It can be Blender3D NormalWalkCycle.gifemployed to determine functional mobility, gait, and vestibular function.
Time frame: before and after intervention(Approximately 14 minutes)
Timed up and go test
test for gait speed and gait balance
Time frame: before and after intervention(Approximately 14 minutes)
Fugl-Meyer Assessment
a stroke-specific, performance-based impairment index. It is designed to assess motor functioning, balance, sensation and joint functioning in patients with post-stroke hemiplegia.
Time frame: before and after intervention(Approximately 14 minutes)
Tinetti Performance Oriented Mobility Assessment
Task-oriented outcome measure that assesses gait and balance ability; is composed of a 9-item gait portion (POMA-G) and 7-item balance portion (POMA-B)
Time frame: before and after intervention(Approximately 14 minutes)
