Objective? To explore the family function of stroke patients and their rehabilitation exercise compliance level, as well as the correlation between them. Methods? By convenience sampling, totally 400 stroke patients undergoing re-examination in Department of Neurology, a ClassⅢ Grade A hospital in Zhejiang Province from June 15th, 2018 to December 15th 2018 were selected as the research objects. General Information Questionnaire, Questionnaire of Exercise Adherence(EAQ),Family Assessment Device(FAD) were adopted in the study. A total of 400 questionnaires were distributed and 389 valid ones were collected. Results? The 389 stroke patients had a total score of (37.07±11.55) in EAQ and (115.78±32.75)in FAD. The dimensional scores in family function(except emotional intervention) were negatively correlated with the total score of rehabilitation exercise compliance (P＜ 0.05). The total score of FAD was negatively correlated with each dimensional scores of EAQ (P＜ 0.05). Multivariate linear regression analysis indicated that, problem-solving, communication, role, emotional reaction, behavior control and the overall family function were the influencing factors of the patient's exercise compliance (P＜ 0.05). Conclusions? The stroke patients' family function and rehabilitation exercise compliance have great space to improve. For those with good family function, their rehabilitation exercise compliance is also good. Improving family function, especially coming up with effective problem-solving plan, is the effective way to improve the stroke patients' rehabilitation exercise compliance.
