The sitting-unsupported balance score as an early predictor of functional prognosis in stroke patients: a pilot study

To evaluate the impact of initial "sitting-unsupported" Berg Balance Scale (SUB), the specific trunk control parameter, on patients' functional outcome, Korean version of Modified Barthel Index (K-MBI) at 6 months. The charts of 30 patients retrospectively reviewed reviewed. The initial Korean version of Berg Balance Scale (K-BBS) including SUB along with patients' Korean version of Mini-Mental State Examination (K-MMSE), Glasgow Coma Scale (GCS), and other functional parameters that affect functional outcome were recorded. Cases were divided into low (group I) and high (group II) initial SUB score groups. Correlation and regression analysis were performed to assess the relationship between the initial SUB on the K-MBI at 6 months. The mean±standard deviation score of initial SUB/K-MBI at 6 months of groups I and II were 0.056±0.236/26.89±32.48, 3.58±0.515/80.25±18.78, respectively, and showed statistical significant differences to each other (p
