title: The Reference Values for the Chair Stand Test in Healthy Japanese Older People: Determination by Meta-analysis.
abstract: [Purpose] The aim of this study was to determine the reference values for the chair stand test (CST) in healthy older Japanese people. [Methods] Relevant research articles for the 5-repetition chair stand test (CS-5) and the 30-second chair stand test (CS-30) were identified by electronic database and manual searching. Research articles involving healthy Japanese people aged 60 years and older were included in a meta-analysis. Weighted means of the CS-5 and CS-30 were estimated by the random effect model as the reference values for the CST. Further, the effects of age and sex on the reference values were analyzed by a meta-regression analysis. [Results] Seven articles (21 data) and three articles (14 data) were included in the meta-analyses for the CS-5 and CS-30, respectively. The reference value for the CS-5 was estimated as 8.50 sec [95% confidence interval (CI): 7.93-9.07]; age and sex were not associated with this reference value. The reference value for the CS-30 was estimated as 17.26 times [95%CI: 15.98-18.55], and age was significantly associated with this value. [Conclusion] When the CS-5 and CS-30 are used to evaluate elderly Japanese people, the reference values for the CS-5 and CS-30 determined in this study would be useful indices.
