The purpose of this study was to investigate effect of hospital-based physical and occupational therapy on Modified Barthel Index (MBI) score in stroke inpatients at least 3 months after stroke, to predict MBI score at discharge from subscales of MBI, and determine the characteristics of stroke at admission. Forty-five stroke inpatients participated and received physical and occupational therapy for two months. All participants were assessed on MBI at admission and discharge. The collected data was analyzed by dependency level (MBI${leq}$74 and MBI${geq}$75) at admission. The results revealed that the MBI score at discharge was significantly improved compared to the MBI score at admission in the group with more than moderate dependency level (MBI${leq}$74). In particular, personal hygiene, dressing, ambulation, and chair/bed transfer were improved. But only ambulation was improved significantly in the group with a less than mild dependency level (MBI${geq}$75). The chair/bed transfer, dressing, ambulation, and Mini-Mental State Exam-Korea score at admission were important factors in the MBI score at discharge. Eighty-six percent of the variation in MBI score function at discharge can be explained. Therefore, it is suggested that hospital-based physical and occupational therapy in subacute stroke improve independent living status, especially for patients with a more than moderate dependency level.
