RESUMO
Introducción y objetivos La imaginería motora es una técnica ampliamente utilizada en la rehabilitación neurológica. Su utilidad y resultados vienen condicionados por la habilidad de imaginar el movimiento, que puede ser evaluada por diversos instrumentos. Este estudio pretende evaluar las propiedades psicométricas de un instrumento de reciente creación dedicado, en concreto, a la mano/miembro superior: Cuestionario de evocación mental de imágenes, movimientos y actividades. Materiales y métodos Fueron evaluados 29 sujetos (41% varones y 59% mujeres), con un promedio de 45 años de edad. A todos ellos se les administró, en un primer encuentro, el «Cuestionario de evocación mental de imágenes, movimientos y actividades» y el «Movement Imagery Questionnaire-Revised» en su versión española. En un segundo encuentro se les realizó el retest del Cuestionario de evocación mental de imágenes, movimientos y actividades. Se calcularon: estadísticos descriptivos, consistencia interna, fiabilidad test-retest, reproducibilidad y validez concurrente entre ambos instrumentos. Resultados Fiabilidad/consistencia interna: se hallaron buenos índices de consistencia interna de la prueba tanto para la escala global como para sus 2 subescalas: evocación y sensación. Fiabilidad/test-retest: no se hallaron diferencias significativas en el intervalo de una semana. Reproducibilidad: se halló un excelente coeficiente de correlación intraclase. Validez concurrente: el Cuestionario de evocación mental de imágenes, movimientos y actividades tiene una fuerte correlación con el Movement Imagery Questionnaire-Revised. Conclusiones El Cuestionario de evocación mental de imágenes, movimientos y actividades es un instrumento psicométricamente sólido que puede ser utilizado para medir la habilidad para formar mentalmente imágenes visuales y cinestésicas de la mano/miembro superior, a la vez que proporciona información del proceso de imaginación por el que pasa la persona que está siendo evaluada (AU)
Introduction and objectives Motor imaging is a widely used technique in neurological rehabilitation. Its utility and results are influenced by the ability to imagine a movement, which can be evaluated by various instruments. This study aimed to assess the psychometric properties of a recently-designed instrument for assessment of the hand and arm: the Mental Evocation of Images, Movements and Activities Questionnaire. Materials and methods We assessed 29 patients (41% men and 59% women) with a mean age of 45 years. At a first visit, all were administered the Mental Evocation of Images, Movements and Activities Questionnaire and the Spanish version of the Movement Imagery Questionnaire-Revised. At a second visit, the patients underwent a retest of the Mental Evocation of Images, Movements and Activities Questionnaire. We calculated descriptive statistics, internal consistency, test-retest reliability, reproducibility and concurrent validity between the two instruments. Results Reliability/internal consistency: we found good indexes of internal consistency both for the global scale and for its two subscales: evocation and sensation. Reliability/test-retest: we found no significant differences in a 1-week interval. Reproducibility: we found an excellent intraclass correlation coefficient. Concurrent validity: the Mental Evocation of Images, Movements and Activities Questionnaire showed a strong correlation with the Movement Imagery Questionnaire-Revised. Conclusions The Mental Evocation of Images, Movements and Activities Questionnaire is a psychometrically robust instrument that can be used to measure the ability to form visual and kinesthetic mental images of the hand/arm. The instrument also provides information on the imaging process in the person under evaluation (AU)
