El objetivo es analizar las propiedades psicom\u00e9tricas de la Escala Observacional de la Marcha del Sujeto con Amputaci\u00f3n de la Extremidad Inferior (OMSAEI): fiabilidad intra e interobservador, cambio m\u00ednimo detectable (CMD95) y validez de constructo.\nMetodolog\u00eda. Se realiz\u00f3 un estudio observacional con personas con amputaci\u00f3n del miembro inferior (AMI) unilateral. Las grabaciones de la marcha se realizaron en condiciones controladas y fueron evaluadas por dos profesionales que aplicaron la escala OMSAEI organizada en dos secciones: 1- evaluaci\u00f3n de patrones cinem\u00e1ticos, centrados en el an\u00e1lisis de la movilidad articular, y 2- evaluaci\u00f3n de par\u00e1metros espaciotemporales. Se analizaron el coeficiente de correlaci\u00f3n intraclase (CCI), los gr\u00e1ficos de Bland-Altman y la correlaci\u00f3n de Pearson con la escala de Houghton.\nResultados. Participaron 37 personas, 56,8%, mujeres y edad 45,6 a\u00f1os (DE=13,8). La fiabilidad intraobservador fue excelente (CCI total=0,996; secci\u00f3n 1=0,988; secci\u00f3n 2=0,995), con un CMD95 de 0,12 puntos. La fiabilidad interobservador tambi\u00e9n fue excelente (CCI total=0,987; secci\u00f3n 1=0,966; secci\u00f3n 2=0,986), con un CMD95 de 0,36 puntos. Los gr\u00e1ficos de Bland-Altman mostraron l\u00edmites de acuerdo estrechos: \u00b11,4 puntos (intra) y \u00b12,28 puntos (inter). La validez de constructo fue alta y significativa (r= -0,773; p&lt;0,001), indicando una fuerte correlaci\u00f3n inversa con la escala de Houghton.\nConclusiones. La escala OMSAEI es una herramienta fiable y v\u00e1lida para realizar una evaluaci\u00f3n objetiva y estructurada del patr\u00f3n de marcha en personas con AMI unilateral. Su dise\u00f1o espec\u00edfico y sus excelentes propiedades psicom\u00e9tricas la convierten en un instrumento \u00fatil tanto en contextos cl\u00ednicos como de investigaci\u00f3n.<\/jats:p>","DOI":"10.23938\/assn.1152","type":"journal-article","created":{"date-parts":[[2026,2,10]],"date-time":"2026-02-10T09:41:57Z","timestamp":1770716517000},"page":"e1152","source":"Crossref","is-referenced-by-count":0,"title":["Propiedades psicom\u00e9tricas de la Escala Observacional de la Marcha del Sujeto con Amputaci\u00f3n de la Extremidad Inferior","Psychometric properties of the Observational Gait Scale for Persons with Lower limb Amputation"],"prefix":"10.23938","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-5345-9990","authenticated-orcid":false,"given":"Ar\u00e1nzazu","family":"Cort\u00e9s Rodr\u00edguez","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5242-9130","authenticated-orcid":false,"given":"David","family":"Hern\u00e1ndez Herrero","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2054-3622","authenticated-orcid":false,"given":"Isabel Mar\u00eda","family":"Alguacil Diego","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6394-7037","authenticated-orcid":false,"given":"\u00c1ngela","family":"Aguilera Rubio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-2423-1106","authenticated-orcid":false,"given":"M\u00f3nica","family":"Gonz\u00e1lez Nu\u00f1o","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8616-5505","authenticated-orcid":false,"given":"Francisco","family":"Molina Rueda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10024","published-online":{"date-parts":[[2026,2,10]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"1.
