The psychometric properties of the BBS confirmed that it measures the unidimensional construct of balance ability with adequate validity and with goodness of fit and structural integrity that meet the acceptability criteria. Person measures revealed that some participants scored near the top of the BBS, suggesting a ceiling effect; item measures revealed that participants with leg amputations had the most difficulty performing the following tasks: standing with 1 leg in front, turning 360 degrees, and placing alternate foot on a stool.<\/jats:p><\/jats:sec><jats:sec><jats:title>Limitations<\/jats:title><jats:p>Limitations included a convenience sample and a lack of rater reliability testing.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The BBS cohered with the unidimensional construct of balance ability and had strong internal validity for use in a variety of people with leg amputations.<\/jats:p><\/jats:sec>","DOI":"10.2522\/ptj.20130009","type":"journal-article","created":{"date-parts":[[2013,6,7]],"date-time":"2013-06-07T04:11:16Z","timestamp":1370578276000},"page":"1520-1529","source":"Crossref","is-referenced-by-count":51,"title":["Preliminary Assessment of Balance With the Berg Balance Scale in Adults Who Have a Leg Amputation and Dwell in the Community: Rasch Rating Scale Analysis"],"prefix":"10.1093","volume":"93","author":[{"given":"Christopher Kevin","family":"Wong","sequence":"first","affiliation":[{"name":"C.K.
