abstract="INTRODUCTION: Balance impairment occurs after a hip fracture, but the characteristics of the impairment are not clear. <br><br>OBJECTIVE: To investigate the uni-dimensionality, fit statistics, and item difficulty of the Berg Balance Scale (BBS) in older adults with hip fracture by conducting a Rasch analysis. <br><br>METHODS: This was an observational cross-sectional study. The 254 participants were all ≥ 65 years old and had been hospitalized for rehabilitation after a unilateral hip fracture incurred during a fall. We collected their BBS scores at the time of hospital discharge and conducted a Rasch analysis to examine the uni-dimensionality, fit statistics, and item difficulty. <br><br>RESULTS: The principal component analysis (PCA) of the Rasch model demonstrated that the BBS is uni-dimensional. The information-weighted mean square (MnSq) fit statistic was within the range of fit criteria for all items. The underfit item of the outlier-sensitive MnSq fit statistics was &quot;Standing unsupported eyes closed&quot; with the MnSq of 2.06. The difficult items were in order of logits: &quot;Standing on one leg&quot; (logits = 4.01); &quot;Step tool&quot; (logits = 2.74); and &quot;Turn 360°&quot; (logits = 2.61). <br><br>CONCLUSION: The BBS is uni-dimensional and conforms with the Rasch model. The BBS most difficult items for older adults with a hip fracture required one-legged support and dynamic balance.<p /> <p>Language: en</p>",
