Objective The aim of the study was to investigate the validity of using total score and to examine the constitution and characteristics of the Basic Movement Scale in postsurgery patients with hip fracture. Design The dimensionality and the threshold difficulty intervals between each score and item difficulty hierarchy of the Basic Movement Scale were examined using factor analysis and Rasch analysis in 37 patients admitted to our hospital between April and November 2015. Results For factor analysis, the contribution ratio of the first factor was 78.9%, that of the second factor was 6.5%, and there were no items that fit the Rasch analysis. The threshold was reversed at 6 of the 48 locations. The difficulty of the 12 Basic Movement Scale items was distributed roughly evenly among all 9 lots, with some deviation. There was one very easy item, and there were some items almost overlapping in difficulty. Conclusions The results showed a unidimensional association between the items and evaluation index. The difficulty threshold of each score was approximated to the interval scale. Therefore, the Basic Movement Scale has evident construct validity and enables quantitative evaluation of physical ability, assessment of the effects of daily training, and general predictions of the feasibility of patients' clinical goals.
