“…This result does not match those previously described in the scientific literature either in professional skills, 14,30,49,50 sport activities, 51-54 or both 55 or even in people with motor disability. 56-58 Focusing on the possible different efficacies of MI and AO, Gonzalez-Roja et al 59 compared these cognitive tools in promoting early learning of a complex 4-limb, hand-foot coordination task. On the basis of electroencephalogram pattern analysis, they reported that AO was more effective than MI in promoting early learning of a new coordination task.…”

Implementing Cognitive Training Into a Surgical Skill Course: A Pilot Study on Laparoscopic Suturing and Knot Tying

et al. 2018

Mini-invasive surgery-for example, laparoscopy-has challenged surgeons' skills by extending their usual haptic space and displaying indirect visual feedback through a screen. This may require new mental abilities, including spatial orientation and mental representation. This study aimed to test the effect of cognitive training based on motor imagery (MI) and action observation (AO) on surgical skills. A total of 28 postgraduate residents in surgery took part in our study and were randomly distributed into 1 of the 3 following groups: (1) the basic surgical skill, which is a short 2-day laparoscopic course + MI + AO group; (2) the basic surgical skill group; and (3) the control group. The MI + AO group underwent additional cognitive training, whereas the basic surgical skill group performed neutral activity during the same time. The laparoscopic suturing and knot tying performance as well as spatial ability and mental workload were assessed before and after the training period. We did not observe an effect of cognitive training on the laparoscopic performance. However, the basic surgical skill group significantly improved spatial orientation performance and rated lower mental workload, whereas the 2 others exhibited lower performance in a mental rotation test. Thus, actual and cognitive training pooled together during a short training period elicited too high a strain, thus limiting potential improvements. Because MI and AO already showed positive outcomes on surgical skills, this issue may, thus, be mitigated according to our specific learning conditions. Distributed learning may possibly better divide and share the strain associated with new surgical skills learning.

“…Motor imagery represents a valuable tool in skill training (Blair et al 1993;Denis 1985), and in rehabilitation following central or peripheral injury (Grabherr et al 2015;Harris and Hebert 2015). Empirical investigations of motor imagery contribute greatly to understanding the internal mental representation underlying action production Moran et al 2012;Rodriguez et al 2008;Vogt et al 2013).…”

Executive functions in motor imagery: support for the motor-cognitive model over the functional equivalence model

2020

The motor-cognitive model holds that motor imagery relies on executive resources to a much greater extent than do overt actions. According to this view, engaging executive resources with an interference task during motor imagery or overt actions will lead to a greater lengthening of the time required to imagine a movement than to execute it physically. This model is in contrast to a currently popular view, the functional equivalence model, which holds that motor imagery and overt action use identical mental processes, and thus should be equally affected by task manipulations. The two competing frameworks were tested in three experiments that varied the amount and type of executive resources needed to perform an interference task concurrent with either an overt or imagined version of a grasping and placing action. In Experiment 1, performing a concurrent calculation task led to a greater lengthening of the time required to execute motor imagery than overt action relative to a control condition involving no interference task. Further, an increase in the number of responses used to index performance affected the timing of motor imagery but not overt actions. In Experiment 2, a low-load repetition task interfered with the timing of motor imagery, but less so than a high load calculation task; both tasks had much smaller effects on overt actions. In Experiment 3, a word generation task also interfered with motor imagery much more than with overt actions. The results of these experiments provide broad support for the motor-cognitive model over the functional equivalence model in showing that interfering with executive functions had a much greater impact on the timing of motor imagery than on overt actions. The possible roles of different executive processes in motor imagery are discussed.

“…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.…”

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.
