Purpose: This study aims to investigate the fear of falling of stroke patients and identify factors affecting the fear of falling. Method: For basic data, structured questionnaires were used for 137 stroke patients in hospitals in B city sampled for this study from June to August, 2010. Results: A multiple regression analysis used to identify variables affecting the fear of falling of stroke patients indicates that the most affecting variable was activities of daily living (${eta}$=-.558), followed by self-efficacy of falling (${eta}$=-.223), primary caregiver (${eta}$=-.118), perception of health (${eta}$=-.128) and drunken status (${eta}$=-.108). Total variance explained by activities of daily living, self-efficacy of falling, the primary caregiver, perception of health and drunken status was 81.2% (F=70.845, $R^2$=.812). Conclusion: As discussed above, the factors significantly affecting the fear of falling in stroke patients were activities of daily living and self-efficacy of falling. Therefore, in order to reduce fear of falling of stroke patients and prevent falling, it is suggested that programs should be developed that will improve self-efficacy of falling and daily living activities.
