RESUMO
The assessment of trunk sway smoothness using an accelerometer sensor embedded in a smartphone could be a biomarker for tracking motor learning. This study aimed to determine the reliability of trunk sway smoothness and the effect of visual biofeedback of sway smoothness on motor learning in healthy people during unipedal stance training using an iPhone 5 measurement system. In the first experiment, trunk sway smoothness in the reliability group (n = 11) was assessed on two days, separated by one week. In the second, the biofeedback group (n = 12) and no-biofeedback group (n = 12) were compared during 7 days of unipedal stance test training and one more day of retention (without biofeedback). The intraclass correlation coefficient score 0.98 (0.93-0.99) showed that this method has excellent test-retest reliability. Based on the power law of practice, the biofeedback group showed greater improvement during training days (p = 0.003). Two-way mixed analysis of variance indicates a significant difference between groups (p < 0.001) and between days (p < 0.001), as well as significant interaction (p < 0.001). Post hoc analysis shows better performance in the biofeedback group from training days 2 and 7, as well as on the retention day (p < 0.001). Motor learning objectification through visual biofeedback of trunk sway smoothness enhances postural control learning and is useful and reliable for assessing motor learning.

La leucemia linfocítica aguda (LLA), es la neoplasia más frecuente en los niños, el tratamiento actual en nuestro medio, está basado en el protocolo de la Sociedad Boliviana de Hematología y Hematoterapia homologado al grupo Franco Americano-Británico. se reporta el caso de un niño con diagnóstico clínico-laboratorial de LLA tratado en el servicio de hematología del Hospital "Dr, Mendoza", actualmente en la 119na. semana de la fase de mantenimiento, etapa a la que antes no se había podido llegar concluida ésta, ingrasará a la etapa de valoración, esperádose al término de los cinco años certificar la Remisión completa del cuadro. Se enfatiza el esquema terapeútico de la enfermedad
