Three evaluation scales are available, including the Fatigue Impact Scale （FIS）. Yet none of these has been proven to be of use in the evaluation of psychological quality after post-stroke fatigue. OBJECTIVE： To introduce FIS into China, and to evaluate the validity and reliability of the Chinese Version in patients with cerebral infarction. DESIGN： Scale evaluation. SETTING： Department of Rehabilitation, Beijing Friendship Hospital, Capital Medical University. PARTICIPANTS： A total of 330 patients with cerebral infarction were selected from the Department of Neurology, Beijing Friendship Hospital, Capital Medical University from June 2005 to December 2006. All patients met diagnostic standards from the Fourth National Cerebrovascular Disease Academic Meeting of China Medical Association and were diagnosed with CT or MRI examination. Patients who were not willing to accept scale evaluation were excluded. METHODS： The English version of FIS was translated into Chinese and subsequently translated back to English again. FIS was given to the discharged patients, and they returned them upon completion. In-patients completed and immediately returned the FIS. Validity and reliability of the retrieved scales were ascertained with descriptive and inference analysis. MAIN OUTCOME MEASURES： Total scores and subscale scores of FIS. RESULTS： Out of 330 questionnaires, 214 valid questionnaires were deemed valid in total. Six components were extracted in factor analysis, and the total cumulative contribution was 73.919%, which suggested the questionnaire was valid. After correlation analysis, 6 components were divided into 3 subscales, including cognitive, physical, and social, which was the same as the English version. The Cronbach α value for the three subscales was 0.937 7, 0.918 8, and 0.940 6, respectively （〉 0.7）.

Eight sport students performed an incremental bicycle exercise test under normoxic and hypoxic （12.7% 02） conditions respectively. EEG and NIRS recordings of the prefrontal cortex （PFC, Brodmarm area 10.46） were performed synchronously to shed light on their correlation. ANOVA revealed a higher absolute workload （231.3 ＋ 37.2 W）, and relative PFC oxygenation under normoxic conditions, whereas hypoxic conditions resulted in earlier exhaustion （200 ~ 26.7 W） and reduced PFC oxygenation. NIRS parameters increased remarkably with exercise intensity （P 〈 0.001） and differed between conditions （O2Hb： P 〈 0.001; HHb： P = 0.023; tHb： P = 0.016） and hemispheres （O2Hb： P = 0.023）. For EEG, higher prefrontal cortical current density during compared to pre and post exercise was revealed for both conditions （P 〈 0.001）. No difference between conditions and hemispheres were found. In conclusion, brain cortical activity is not impaired by hypoxia. No correlation between NIRS and EEG, but a moderate correlation between EEG and cardio-vascular parameters and a moderate to high correlation between NIRS and cardio-vascular parameters were found. The results emphasize that the transfer of EEG and NIRS results need to be done with caution.展开更多
