title: Reliability and validity of center of pressure measures for balance assessment in older adults.
abstract: [Purpose] This study was conducted to assess the reliability and validity of center of pressure-based parameters for balance assessment. [Subjects and Methods] Two hundred and forty older adults were evaluated using a force platform and the Berg Balance Scale at 1-week intervals. The intra-class correlation coefficient and the Pearson correlation coefficient were used to test reliability and validity respectively. [Results] The reliability of the 12 selected center of pressure measures was satisfactory (intra-class correlation coefficient = 0.75-0.99) and the validity between the parameters and the Berg Balance Scale was moderate to good (r = -0.62 to -0.88). [Conclusion] Center of pressure-based parameters are reliable and valid measures in older adults.
