Purpose: This pilot study sought to determine the efficacy of using the Developmental Eye Movement (DEM) test in the adult, acquired brain injury (ABI) population to quantify clinically the effects of controlled, laboratory-performed, oculomotor-based vision therapy/vision rehabilitation. Methods: Nine adult subjects with mild traumatic brain injury (mTBI) and five with stroke were assessed before and after an eight-week, computer-based, versional oculomotor (fixation, saccades, pursuit, and simulated reading) training program (9.6 h total). The protocol incorporated a cross-over, interventional design with and without the addition of auditory feedback regarding two-dimensional eye position. The clinical outcome measure was the Developmental Eye Movement (DEM) test score (ratio, errors) taken before, midway, and immediately following training. Results: For the DEM ratio parameter, improvements were found in 80–89% of the subjects. For the DEM error parameter, improvements were found in 100% of the subjects. Incorporation of the auditory feedback component revealed a trend toward enhanced performance. The findings were similar for both DEM parameters, as well as for incorporation of the auditory feedback, in both diagnostic groups. Discussion: The results of the present study demonstrated considerable improvements in the DEM test scores following the oculomotor-based training, thus reflecting more time-optimal and accurate saccadic tracking after the training. The DEM test should be considered as another clinical test of global saccadic tracking performance in the ABI population. Resumen: Objetivo: Este estudio piloto trató de determinar la eficacia del uso de la prueba DEM (Developmental Eye Movement) en la población adulta con daño cerebral adquirido (DCA) para cuantificar clínicamente los efectos de la rehabilitación/terapia visual controlada, realizada en laboratorio, y de carácter oculomotor. Métodos: Se valoraron nueve sujetos adultos con daño cerebral traumático leve (mTBI) y cinco con ictus, con anterioridad y posterioridad a un programa de entrenamiento de ocho semanas, informático oculomotor y versional (movimientos de fijación, sacádicos, de persecución y lectura simulada, de 9,6 horas en total). El protocolo incorporó un diseño cruzado e intervencional, con y sin adición de retroalimentación auditiva en relación a la posición bi-dimensional de los ojos. La medida del resultado clínico se llevó a cabo mediante la puntuación de la prueba DEM (Developmental Eye Movement) (ratio, errores) realizada con anterioridad, en el punto medio, e inmediatamente tras el entrenamiento. Resultados: Para el parámetro de ratio DEM, se encontraron mejoras en el 80-89% de los sujetos. Para el parámetro de error DEM, se encontraron mejoras en el 100% de los sujetos. La incorporación del componente de retroalimentación auditiva reveló una tendencia hacia la mejora del rendimiento. Los hallazgos fueron similares para ambos parámetros DEM, así como para la incorporación de la retroalimentación auditiva, en ambos grupos diagnósticos. Discusión: Los resultados del presente estudio demostraron mejoras considerables de las puntuaciones de la prueba DEM tras la terapia oculomotora, lo que refleja una mayor optimización y precisión del seguimiento sacádico en el tiempo tras la terapia. Deberá considerarse la prueba DEM como una prueba clínica para valorar el rendimiento del seguimiento sacádico global en la población de DCA.
