“…First, in patients suffering from severe motor deficits after stroke motor imagery is a very good approximation of overt movement and actually activates primary motor cortices. Second, care has to be taken if one aims at transferring the results gained by HVs to patients since the functional neuroanatomical correlates of motor imagery differed between the groups (see also Stinear et al, 2007).…”

“…It has been suggested that the primary motor cortex (M1) on the side of the stroke affects lateralization during MI (30,31). However, the lateralization effect was not identified in the inferior precentral area of either side of the brains of the stroke patients.…”

“…This difference may be due to several reasons. Different studies include distinct patient populations; in the present study only patients with a disease duration of 3-6 months were selected, while two other studies (30,31) included stroke patients with a disease duration of ≥8 months. In addition, different regions of interest are investigated among studies.…”

Abstract. Stroke is a leading cause of impairment and disability worldwide, and motor imagery (MI) has been used in stroke rehabilitation. Electroencephalography (EEG) has been used to study MI. However, the characteristic features of EEG during MI in stroke patients have not been established. The purpose of this study was to investigate the difference in event-related potentials (ERPs) during MI between healthy controls and stroke patients. This study included nine stroke patients and nine healthy age-matched controls, who performed tasks involving MI, passive movement without MI and passive movement with MI. One hundred and twenty-eight channel ERPs were recorded to capture cerebral activation. Electrodes E44 and E120 (corresponding to the inferior precentral area) were selected to analyze the lateralization effects of ERPs. Lateralization was calculated as the ratio of the potential at 500 ms at electrode E120 to that at electrode E44. In the controls, the different ERPs exhibited differential direction between the 0-300 and the 300-700 ms interval. ERPs were evoked by passive movement with MI and MI alone, but not passive movement without MI. In addition, a lateralization effect in control patients as shown by the observation that the lateralization ratio in passive movement with MI and MI alone was significantly different from that in passive movement without MI (P<0.05). The amplitudes of the different ERPs were significantly smaller in stroke patients compared with those in the controls (P<0.05). The lateralization ratio in the stroke patients was opposite and significantly different from that of the controls (P<0.05). The results suggested that the MI-induced lateralization effect in ERPs may be used as a measure for evaluating the MI impairment and recovery in stroke patients.

“…La hipótesis de que las redes neuro-cognitivas son las mismas tanto para los movimientos reales como imaginados podría explicar estos resultados (Fourkas et al, 2008;Kasess et al, 2008;Ramnani, 2006;Stinear et al, (2007).…”

“…Otras investigaciones se han centrado en: la activación de las áreas corticales y subcorticales durante la representación motriz (Fourkas Bonavolontà, Avenanti y Aglioti, 2008;Kasess et al, 2008;Ramnani, 2006); las imágenes motrices en pacientes con lesiones cerebrovasculares (Cicinelli et al, 2006;Sabaté, González y Rodriguez, 2007;Stinear Fleming, Barber y Byblow, 2007); o en paciente con enfermedad de Parkinson (Amick, Schendan, Ganis y Cronin-Golomb, 2006;Helmich, Lange, Bloem y Toni, 2007). En resumen, estos estudios neuronales sobre la representación mental han observado consistentemente que los patrones de activación son comunes tanto a la simulación mental del movimiento como a la generación real del mismo.…”

RESUMENEstudios recientes observaron que las imágenes motrices se desarrollan de forma entrelazada con el desarrollo de las habilidades motrices en niños. La finalidad de este estudio es analizar en qué medida la imagen motriz de los elementos necesarios para resolver un problema motor (la recepción de un balón), se relaciona con los niveles de habilidad en niños (3 -9 años). La muestra estuvo formada por 215 participantes (87 chicos y 118 chicas), (M = 5,94, DT = 1,47). Se ha utilizado una metodología mixta: dibujos, indicaciones gestuales, verbalización del pensamiento y una prueba práctica de recepción de balón. El MANOVA reveló diferencias significativas en las capacidades meta-cognitivas y motrices en función de las etapas de desarrollo. Un análisis de ecuaciones estructurales reveló que las capacidades meta-cognitivas median la relación entre las etapas de desarrollo y la habilidad de recepción de móviles. Se discuten sus repercusiones en el aprendizaje motor.
