The questionnaires were concurrently administered to a convenience sample of 98 consecutively recruited individuals with lower limb amputation (LLA) (male\/female\u2009=\u200961\/37; mean age 57\u2009\u00b1\u200914\u2009years). LCI-5 showed disordered rating scale thresholds (one response option in three items required collapsing); local dependence between two items (resolved by creating a testlet); underfit of one item (\u2018Get up from the floor\u2019); and presence of a second weak dimension. PMQ 2.0 showed a correctly functioning rating scale; good fit of the data to the model (apart from some overfit); local dependence between two items (absorbed by creating a testlet); and essential unidimensionality. At scale co-calibration onto a common interval-scaled metric, PMQ 2.0 was better targeted than LCI-5 (i.e. the extent of item difficulty was more appropriate for the sample) and its operational range allowed a more precise measurement of higher locomotor abilities. The correlation between LCI-5 and PMQ 2.0 scores was rho\u2009=\u2009\u20090.78. In conclusion, LCI-5 revealed some drawbacks, confirming a previous Rasch study; refinement of its rating scale and item selection seems therefore warranted. The PMQ 2.0 demonstrated good overall measurement quality, in line with previous Italian and Slovene studies. The operational range of the PMQ 2.0 makes it more suitable than LCI-5 for assessing people with high locomotor abilities.<\/jats:p>","DOI":"10.1097\/mrr.0000000000000478","type":"journal-article","created":{"date-parts":[[2021,5,25]],"date-time":"2021-05-25T22:06:41Z","timestamp":1621980401000},"page":"233-240","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":9,"title":["Rasch validation and comparison of the German versions of the Locomotor Capabilities Index-5 and Prosthetic Mobility Questionnaire 2.0 in lower-limb prosthesis users"],"prefix":"10.1097","volume":"44","author":[{"given":"Alexander","family":"Ranker","sequence":"first","affiliation":[{"name":"Department of Rehabilitation Medicine, Medical School Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph","family":"Gutenbrunner","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Medical School Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabelle","family":"Eckhardt","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Medical School Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Giordano","sequence":"additional","affiliation":[{"name":"Bioengineering Unit, Istituti Clinici Scientifici Maugeri, IRCCS, Institute of Veruno (NO), Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helena","family":"Burger","sequence":"additional","affiliation":[{"name":"University Rehabilitation Institute"},{"name":"Faculty of Medicine, University of Ljubljana, Ljubljana, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Franco","family":"Franchignoni","sequence":"additional","affiliation":[{"name":"Physical Medicine and Rehabilitation Department, Istituti Clinici Scientifci Maugeri, IRCCS, Institute of Tradate (VA), Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2021,5,24]]},"reference":[{"key":"R1-20250525","doi-asserted-by":"crossref","first-page":"319","DOI":"10.1016\/j.jamda.2010.12.097","article-title":"Mobility in elderly people with a lower limb amputation: a systematic review.","volume":"13","author":"Fortington","year":"2012","journal-title":"J Am Med Dir Assoc"},{"key":"R2-20250525","doi-asserted-by":"crossref","first-page":"82","DOI":"10.1097\/MRR.0000000000000392","article-title":"The most important activities of daily functioning: the opinion of persons with lower limb amputation and healthcare professionals differ considerably.","volume":"43","author":"van Schaik","year":"2020","journal-title":"Int J Rehabil Res"},{"key":"R3-20250525","doi-asserted-by":"crossref","first-page":"179","DOI":"10.1016\/j.pmr.2013.09.002","article-title":"Outcome instruments for prosthetics: clinical applications.","volume":"25","author":"Heinemann","year":"2014","journal-title":"Phys Med Rehabil Clin N Am"},{"key":"R4-20250525","doi-asserted-by":"crossref","first-page":"92","DOI":"10.1007\/s40141-020-00274-4","article-title":"Selecting, administering, and interpreting outcome measures among adults with lower-limb loss: an update for clinicians.","volume":"8","author":"Sions","year":"2020","journal-title":"Curr Phys Med Rehabil Rep"},{"key":"R5-20250525","doi-asserted-by":"crossref","first-page":"23","DOI":"10.1007\/s11892-020-01305-z","article-title":"Using person-reported outcomes (PROs) to motivate young people with diabetes.","volume":"20","author":"de Wit","year":"2020","journal-title":"Curr Diab Rep"},{"key":"R6-20250525","doi-asserted-by":"crossref","first-page":"763","DOI":"10.1016\/j.avsg.2013.07.011","article-title":"A systematic review of functional and quality of life assessment after major lower extremity amputation.","volume":"28","author":"Hawkins","year":"2014","journal-title":"Ann Vasc Surg"},{"key":"R7-20250525","doi-asserted-by":"crossref","first-page":"8","DOI":"10.1186\/s12913-018-3759-5","article-title":"Amputation rates of the lower limb by amputation level -
