Objectives

Narrative objectives1

The subjects participated in this study are normal volunteers and patients who experienced ischemic cerebrovascular diseases but recovered to have good status for physical activity including exercise. The aim of the present study is to investigate changes in regional cerebral blood flow induced by exercise using PET with autoradiography method. The subjects perform exercise with lower intensity than 40% of peak pulmonary oxygen uptake.

Basic objectives2

Others

Basic objectives -Others

We examine the regions where changes in cerebral blood flow differ between normal volunteers and patients who experienced ischemic cerebrovascular diseases and elucidate possible risks induced by exercise.

Assessment

Primary outcomes

Changes in regional cerebral blood flow induced by exercise will compared between normal volunteers and patients who experienced ischemic cerebrovascular diseases, which will be evaluated after examining data of 8 subjects in the both groups (12~15 weeks from the onset of the study).

Key secondary outcomes

For patients who experienced ischemic cerebrovascular diseases, the association between ischemic regions and the magnitude of changes in regional cerebral blood flow induced by exercise will be evaluated after examining data of 12 subjects in the patients group (24~30 weeks from the onset of the study).

Key inclusion criteria

Normal volunteers and patients who experienced ischemic cerebrovascular diseases whose age ranged from 20 to 50 years old are included if they are tolerable for continuing supine cycling ergometer exercise with lower intensity than 40% of peak pulmonary oxygen uptake for 20 minute.

Key exclusion criteria

The subjects are excluded if they are not tolerable for performing the 20 min of continuous exercise, as a results of physical examination and exercise tests.

Results

As of June 2017, PET measurements were performed for fourteen normal volunteers and five patients suffered from ischemic cerebrovascular diseases in Tokyo Metropolitan Institute of Gerontology. For each subject, regional cerebral blood flow was investigated on six occasions while these subjects remained at rest, performed physical exercise on cycling ergometer at supine position and remained at rest again. rCBF was calculated by autoradiography method with 15O-H2O and functional imaging for rCBF was analyzed with SPM and Dr. View software. There were no adverse events and data were obtained according to the experimental protocols approved before.

Other

Other related information

Changes in regional cerebral blood flow during exercise are investigated by PET. As healthy volunteers are examined for a control group, patients of ischemic cerebrovascular diseases are also examined in order to clarify the influence of exercise to the ischemic region. Subjects for a control group are recruited from young healthy volunteers who are examined by exercise tests and medical check-up in Hosei University from 2015 to 2016, while subjects for a patient group are recruited from patients who visited a clinic of department of neurosurgery in Tokyo Medical and Dental University from 2015 to 2016. After examined by brain MRI, PET are performed for measurements of regional cerebral blood flow during exercise and before and following exercise as well. Physiological variables such as blood pressure and heart rate are observed in accordance with the PET procedures.
