Objective To investigate the correlation between cardiopulmonary function and quality of life or daily living ability in stroke patients with hemiplegia. Methods Totally 39 stroke patients in Affiliated Rehabilitation Hospital,Fujian University of Traditional Chinese Medicine from March 2013 to August 2015 was collected. A modified version of the Barthel index (MBI) was conducted to evaluate daily living ability while the Medical Outcomes Study 36-item Short-Form (SF-36) was used to evaluate the quality of life of patients. Furthermore, the German Jaeger production company OXYGON PRO PC exercise cardiopulmonary was used to test cardiopulmonary function. By simple correlation analysis and partial correlation analysis, the effect of various indicators of cardiopulmonary function on the daily life ability and quality of life of patients was observed. ResultsThe simple correlation analysis shows that peak oxygen uptake, peak metabolic equivalent, peak oxygen pulse were positively correlated with physical function (r=0.34, 0.34, 0.44, P<0.05), and positively correlated with MB! (r=0.54, 0.54, 0.57, P<0.001), peak oxygen uptake and peak metabolic equivalent were positively correlated with vitality (r=0.34, 0.34, P< 0.05). Partial correlation showed that peak oxygen uptake, peak metabolic equivalent, and peak oxygen pulsewere positively correlated with MBI (r=0.57, 0.57,0.53, P<0.001), and they were positively correlated with vitality (r=0.41,0.41,0.44, P< 0.05). 11H peak was positively correlated with MB (r=0.47,P<0.01). Conclusion The decrease of cardiorespiratory function affects the ability of daily living and the quality of life in stroke patients with hemiplegia. [ABSTRACT FROM AUTHOR]
