“…Much like MI-based upper extremity studies, recent investigations have focused on the use of MI in conjunction with other therapeutic techniques, with the goal of maximizing recovery. An investigation of 40 hemiparetic, ambulatory stroke patients examined the effects of MI training on muscle strength and gait performance [ 80 ]. Twenty patients in the control group underwent task-oriented, lower extremity training four days/week for 45-60 minutes/day for three weeks.…”

Motor imagery (MI), defined as the mental implementation of an action in the absence of movement or muscle activation, is a rehabilitation technique that offers a means to replace or restore lost motor function in stroke patients when used in conjunction with conventional physiotherapy procedures. This article briefly reviews the concepts and neural correlates of MI in order to promote improved understanding, as well as to enhance the clinical utility of MI-based rehabilitation regimens. We specifically highlight the role of the cerebellum and basal ganglia, premotor, supplementary motor, and prefrontal areas, primary motor cortex, and parietal cortex. Additionally, we examine the recent literature related to MI and its potential as a therapeutic technique in both upper and lower limb stroke rehabilitation.

“…In a meta-analysis, Schuster et al (2011) reported that ~17 minutes of motor imagery is optimal to observe positive effects on physical performance (e.g., Yue and Cole, 1992;Grosprêtre et al, 2018;Ranganathan et al, 2004), thus reinforcing the potential for its use in rehabilitation programs (e.g., Jackson et al, 2001;Lebon et al, 2012;Cho et al, 2013;Kumar, 2016). However, the positive effects of motor imagery seem to disappear when motor imagery is performed longer than the optimal duration proposed by Schuster et al (2011).…”

Mental fatigue induced by prolonged motor imagery increases perception of effort and the activity of motor areas

et al. 2021

Recent literature suggests that when prolonged, motor imagery (MI) induces mental fatigue and negatively impacts subsequent physical exercise. The aim of this study was to confirm this possibility with neurophysiological and self-reported measures. Thirteen participants performed 200 imagined isometric knee extension contractions (Prolonged MI condition) or watched a documentary (Control condition), and then performed 150 actual isometric knee extensions.Electroencephalography was continuously recorded to obtain motor-related cortical potential amplitude at Cz electrode (MRCP, index of motor area activity) for each imagined and actual contractions. Electromyography of the vastus lateralis muscle as well as the perceived effort required to perform prolonged MI, watch the documentary, and perform the actual contractions were measured. During prolonged MI, mental fatigue level, the effort required to imagine the contractions and MRCP amplitude increased over time. The increase in the effort required to imagine the contractions was significantly correlated with the MRCP amplitude. During the physical exercise, a significant condition × time interaction revealed a greater increase over time in perceived effort in the prolonged MI condition compared to the control condition, as well as a specific alteration in EMG RMS of the vastus lateralis muscle. These alterations observed in the presence of mental fatigue during actual contractions, combined with those observed during prolonged MI, suggest that prolonged MI may impair the motor command required to perform imagined or actual contractions. While the observed effect of mental fatigue on MRCP amplitude was clear during MI, future studies should tailor the physical exercise to minimize the exerciseinduced decrease in force production capacity and control for its confounding effects on MRCP amplitude in the presence of mental fatigue.

“…La Im surge como una nueva terapia dedicada al manejo y rehabilitación de las secuelas provocadas por Acv, pero en ningún caso excluye a otros tratamientos como la fisioterapia convencional individual 10,[12][13][14][15][16][17][20][21][22] o la utilización de exoesqueletos u otros aparatos de rehabilitación motora 18,19 , si no que la complementa. Los trabajos que combinan Im con terapias convencionales reflejan mejoras significativas en comparación con solo terapias convencionales, pero además el trabajo de Bajaj et al 23 muestra como la Im por si sola obtiene beneficios en la función motora, que además son significativamente mayores cuando se añade fisioterapia al tratamiento con Im.…”

“…Por lo tanto, la Im parece ser una terapia más en la rehabilitación de las funciones motoras, pero no excluye el uso de otras terapias convencionales que por si solas ya obtenían buenos resultados, si no que parece ser una herramienta más a la hora de ayudar al sistema nervioso central a recuperar las capacidades perdidas [18][19][20] . Tal y como reflejan expertos en rehabilitación neurológica, cada paciente obtendrá beneficios de una u otra terapia en función de su afectación, secuelas y proceso de recuperación pero también de su conocimiento previo acerca del movimiento y la función; y en este caso la Im parece ayudar más a aquellas personas con mejor percepción del movimiento o mayor capacidad de comprensión del mismo 18,20,21 .…”

Introducción: Tras un accidente cerebrovascular, aproximadamente el 80% de los pacientes sufren alteraciones motoras de distinta índole. La rehabilitación de estas lesiones supone un reto terapéutico para el cual existen distintas terapias, algunas de ellas emergentes, entre las que destaca la imaginería motora. Este tratamiento presenta potenciales beneficios en aras de una rehabilitación precoz de los déficits motores adquiridos. Debido a que la imaginería motora es una terapia reciente, el objetivo de este trabajo es recabar la literatura científica más actual acerca de la imaginería motora en pacientes que han sufrido un accidente cerebrovascular. Métodos: Se ha llevado a cabo una búsqueda bibliográfica de acuerdo con las normas PRISMA en las bases de datos PubMed, Cinhal, Cochrane, Medline, Scopus, PEDro, Web of Science y SPORTDiscus con las palabras clave “Stroke”, “Imagery” y “Physical Therapy”. Resultados: Se seleccionaron finalmente 15 artículos para la revisión, con resultados similares en cuanto a los beneficios que la imaginería motora aporta a la rehabilitación en pacientes tras accidente cerebrovascular, analizando los efectos de este tratamiento tanto en miembros superiores como inferiores o en la marcha. Conclusiones: La imaginería motora presenta beneficios significativos en la rehabilitación de pacientes tras accidente cerebrovascular, ya sea sola o en combinación con otras terapias convencionales. Palabras clave: Fisioterapia, Rehabilitación,Imaginería Motora, Neurología, Accidente cerebrovascular.
