Activities of daily living (ADL) and instrumental activities of daily living (I-ADL) are tasks of self-care, functional mobility, functional communication, home management, and community living that enable an individual to achieve personal independence. The purpose of this study were to investigate the effect of factors on ADL in stroke patients and to identify the relationship between the function of upper extremities and ability of ADL. Thirty-one stroke patients participated in this study. The results of this study were as follows: 1) There were significant functional gains between admission and discharge on the MFT score, dexterity, and the motor FIM(p<0.01). 2) There were moderate correlation between MFT score of the non-affected side and motor FIM score at discharge(r=0.499, p<0.01) and high negative correlation between dexterity of non-affected hand and motor FIM score at discharge(r=-0.704, p<0.01). 3) There was a significant difference on motor FIM score among academic background groups (p<0.01). 4) There was no significant difference on motor FIM score among caregiver groups (p<0.01). 5) Four factors were found. one factor comprised dexterity of non-affected hand at admission and discharge and duration of treatment. Two factor comprised MFT of non-affected side at admission and discharge and academic background. Three factor comprised MFT of affected side at admission and discharge and caregiver. Four factor comprised sex and affected side.
