RESUMEN

Jiménez Díaz, J., Morera-Castro, M., Chaves-Castro, K., Portuguez-Molina, P., Araya-Vargas, G. y Salazar, W. (2022). Práctica mental, física o combinada en el desempeño y aprendizaje motor: una respuesta meta-analítica. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20(2), 1-37. En el proceso de adquisición de destrezas motrices la práctica es un elemento fundamental por que facilita el aprendizaje; esta práctica puede ser de dos tipos: física o mental. El objetivo del presente estudio fue determinar el tamaño de efecto de la práctica física (PF), práctica mental (PM) y la práctica combinada (PC) a lo largo del proceso de adquisición y retención en el desempeño de las destrezas motrices, utilizando el enfoque meta-analítico y el análisis de posibles variables moderadoras. Se utilizó el modelo de efectos aleatorios para calcular el tamaño de efecto (TE). Se incluyeron 24 estudios y se obtuvo un total de 150 TE, separados en cuatro grupos. En la fase de adquisición se encontró que la PF (TE = 1.75; n = 36; IC = 0.96,3.55; Q = 113; I2 = 92%), la PM (TE = 0.80; n = 36; IC = 0.50,1.09; Q = 108; I 2= 74%) y la PC (TE = 1.78; n = 22; IC = 1.39,2.18; Q = 167; I2 = 79%) mejoraron su desempeño; además, el grupo control (GC) mejoró el desempeño en la adquisición (TE = 0.18; n = 22; IC = 0.02,0.35; Q = 19; I 2= 0%). Una metarregresión indicó que solo la práctica física, mental y combinada predicen significativamente el TE. En la fase de retención, ni la PF (TE = -0.97; n = 9; IC = -0.41,0.02; Q = 12; I2 = 29%), la PM (TE = 0.62; n = 6; IC = -0.19,1.45; Q = 22; I2 = 83%), la PC (TE = -0.01; n = 14; IC = -0.26,0.25; Q = 23; I2 = 46%), ni el GC (TE = -0.15; n = 5; IC = -0.75,0.44; Q = 11; I2 = 66%) presentaron un cambio significativo. Se analizaron las posibles variables moderadoras. Los resultados sugieren que los tres tipos de práctica mejoran en el desempeño en la fase de adquisición; mientras que, en la etapa de retención, favorecen a mantener lo aprendido. La PM, no reemplaza la PF; no obstante, bajo algunas condiciones, se puede complementar la PF con PM.


Jiménez Díaz, J., Morera-Castro, M., Chaves-Castro, K., Portuguez-Molina, P., Araya-Vargas, G. y Salazar, W. (2022). Mental, physical or combined practice in motor performance and learning: a meta-analytical response. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20(2), 1-37. Practice is a key element in the process of acquiring motor skills, because it facilitates learning. This practice can be of either of two types—physical or mental. The objective of the present study is to determine the extent of effect of physical practice (PF), mental practice (PM) and combined practice (PC) throughout the process of acquisition and retention in the performance of motor skills, using a meta-analytical approach and the analysis of possible moderating variables. The random effect model was used to calculate the extent of the effect (TE). A total 24 studies were included, and a total of 150 TE was obtained, separated in four groups. In the phase of acquisition, it was found that the PF (TE = 1.75; n = 36; IC = 0.96,3.55; Q = 113; I2 = 92%), the PM (TE = 0.80; n = 36; IC = 0.50,1.09; Q = 108; I2 = 74%) and the PC (TE = 1.78; n = 22; IC = 1.39,2.18; Q = 167; I2 = 79%) improved their performance; in addition, the control group (GC) improved the performance in acquisition (TE = 0.18; n = 22; IC = 0.02,0.35; Q = 19; I2 = 0%). A meta-regression indicated that only physical, mental and combined practice significantly predict the TE. In the retention phase, neither the PF (TE = -0.97; n = 9; IC = -0.41,0.02; Q = 12; I2 = 29%), the PM (TE = 0.62; n = 6; IC = -0.19,1.45; Q = 22; I2 = 83%), the PC (TE = -0.01; n = 14; IC = -0.26,0.25; Q = 23; I2 = 46%) or the GC (TE = -0.15; n = 5; IC = -0.75,0.44; Q = 11; I2 = 66%) showed a significant change. Possible moderating variables were analyzed. The results suggest that the three types of practice improve performance in the acquisition phase, while in the retention phase they help to keep what has been learned. The PM does not replace PF; however, PF can be complemented with PM under some conditions.

RESUMEN

RESUMEN: El objetivo de este estudio fue determinar el efecto de la práctica mental kinestésica (PMK) en la fuerza y actividad eléctrica muscular (AEM) del bíceps braquial, luego de un periodo de inmovilización del codo en un grupo de personas adultos jóvenes sanos. Un total de 14 personas (18,64 ± 0,92 años de edad) participaron voluntariamente del estudio, a las cuales se les evaluó la fuerza muscular de prensión y la AEM del bíceps braquial utilizando un dinamómetro de mano y un equipo de electromiografía, respectivamente, antes y después de un periodo de inmovilización del brazo no dominante, y se asignaron aleatoriamente a uno de dos grupos: grupo control (GC) o experimental (GE). El GE realizó PMK: tres series de 15 repeticiones con un minuto de descanso entre series, tres veces al día durante los seis días de inmovilización, mientras que el GC no realizó PKM durante su inmovilización. Al aplicar una prueba de ANOVA de dos vías, no se encontraron diferencias significativas en la fuerza ni en la AEM. Sin embargo, la fuerza del GC disminuyó en 23,75%, mientras que la del GE aumentó en 33,19%. Los resultados sugieren que un periodo de inmovilización del codo de seis días no fue suficiente para que la fuerza ni la AEM disminuyan significativamente, lo que supone que la PMK realizada no es necesaria en periodos menores a seis días.


ABSTRACT: The aim of this study was to determine the effect of kinesthetic mental practice (KMP) on the strength and muscular electrical activity (MEA) of the brachial biceps, after a period of immobilization of the elbow in a group of healthy young adults. A total of 14 volunteer participants (18.64 ± 0.92 years of age) were part in the study. The muscle strength and the AEM of the brachial biceps were assessed using a hand dynamometer and an electromyography equipment, respectively, before and after a period of immobilization of the non-dominant arm. After the pretest, they were randomly assigned to one of two groups: control group (GC) or experimental group (GE). The GE performed 3 sets of 15 repetitions with one-minute rest between sets, three times a day of PMK during the 6 days of immobilization, while the GC did not perform PKM during its immobilization. A 2-way ANOVA test (group x measurement) indicated non-significant differences in strength or AEM. However, the strength of the GC decreased by 23.75%, while increased by 33.19% in the GE. The results suggest that a period of immobilization of the elbow of 6 days was not enough for the strength or the AEM to decrease significantly, which means that the PMK is not necessary in periods of immobilization of less than 6 days.

RESUMEN

Objectives: To compare the effects of combined mental and physical practice with physical practice alone on functional independence in Parkinson disease patients. Study design: Randomized control trial. Setting: Tertiary health care center Participants: 30 subjects were recruited with idiopathic Parkinson’s disease, 60-75 years of age, who were between 1.5 -3 on the Hoehn & Yahr classification & had a score of 24 on the modified Mini Mental State Examination (MMSE). They were randomly assigned into two groups i.e. the experimental group (N=15) which received physical practice along with mental imagery & the control group (N=15) which received physical practice alone. Outcome measures: Performance time of functional movement tasks such as supine to standing position & then standing to supine position were measured. In addition to this the Timed Up& Go (TUG) test and the mental, motor & ADL subsets of the Unified Parkinson’s Disease Rating Scale (UPDRS) & Stroop test for cognitive assessment were administered. Results: There was a significant difference in the performance time of supine to standing & standing to supine position (p 0.00), TUG test (p 0.003) & Stroop test errors (p 0.004). However there was no significant difference in the UPDRS and stroop test time scores. Conclusion: This study shows that the experimental group performed better during the functional tasks and cognitive Stroop test, however there was no significant improvement in UPDRS scores.

RESUMEN

BACKGROUND: Mental practice (MP) is a cognitive strategy which may improve the acquisition of motor skills and functional performance of athletes and individuals with neurological injuries. OBJECTIVE: To determine whether an individualized, specific functional task-oriented MP, when added to conventional physical therapy (PT), promoted better learning of motor skills in daily functions in individuals with chronic stroke (13±6.5 months post-stroke). METHOD: Nine individuals with stable mild and moderate upper limb impairments participated, by employing an A1-B-A2 single-case design. Phases A1 and A2 included one month of conventional PT, and phase B the addition of MP training to PT. The motor activity log (MAL-Brazil) was used to assess the amount of use (AOU) and quality of movement (QOM) of the paretic upper limb; the revised motor imagery questionnaire (MIQ-RS) to assess the abilities in kinesthetic and visual motor imagery; the Minnesota manual dexterity test to assess manual dexterity; and gait speed to assess mobility. RESULTS: After phase A1, no significant changes were observed for any of the outcome measures. However, after phase B, significant improvements were observed for the MAL, AOU and QOM scores (p<0.0001), and MIQ-RS kinesthetic and visual scores (p=0.003; p=0.007, respectively). The significant gains in manual dexterity (p=0.002) and gait speed (p=0.019) were maintained after phase A2. CONCLUSIONS: Specific functional task-oriented MP, when added to conventional PT, led to improvements in motor imagery abilities combined with increases in the AOU and QOM in daily functions, manual dexterity, and gait speed. .

RESUMEN

A prática mental (PM) é um método de treinamento pelo qual a representação interna de uma determinada ação motora é repetida diversas vezes com o objetivo de aumentar a performance motora. O objetivo deste estudo piloto foi avaliar a influência aguda da PM sobre as modificações da atividade cerebral utilizando a análise espectral do potencial relacionado a evento (PRE) e a magnitude quadrática da coerência (MSC) nas bandas de frequências delta, alfa e beta. Seis homens saudáveis (idade entre 20-25 anos) participaram deste estudo. Foram realizadas seis sessões individuais de PM baseada em imaginação motora (IM) de flexão e extensão da metacarpofalangeana do dedo indicador da mão dominante. Cada sessão consistiu de 15 minutos de IM, sendo realizada 2 vezes por semana, durante 3 semanas. Foram realizados registros de sinais de eletroencefalografia (EEG) antes e após as sessões de PM, durante: atividade espontânea; IM e; execução do movimento. Os eletrodos foram colocados nas derivações C3, C4 e Cz, de acordo com o sistema internacional 10-20. A potência do PRE e a MSC foram analisados para a derivação C3. Após o treinamento com a PM houve um aumento significativo (p = 0,03) na potência do PRE (normalizado com a potência da atividade espontânea) na banda delta durante a IM e o movimento do dedo. Além disso, houve aumento estatisticamente significativo da MSC durante a IM (F = 8,85, p = 0,001) e execução do movimento (F = 2,37; p = 0,048). Estes resultados sugerem a necessidade de se avaliar as mudanças na banda delta após a PM em novos estudos.


Mental Practice (MP) is a training method by which internal representation of a motor action is repeated several times to increase the individual's functional performance. This pilot study aimed to assess the acute influence of MI-based MP in oscillatory brain activity changes related to event related potential (ERP) power and magnitude square of coherence (MSC) at delta, alpha and beta frequencies. Six healthy volunteers (aged 20-25 years) participated in this study. One-on-one 15-minute MP training sessions were provided two days per week for three weeks. The MP sessions were performed based on motor imagery (MI) of the metacarpophalangeal flexion and extension of the dominant hand index finger. Electroencephalography signals were recorded before and after the training program, during spontaneous activity, MI and movement. Electrodes were positioned at C3, C4 and Cz locations, in accordance with the 10-20 international system. The ERP power and MSC were analized at C3 derivation. After MP, the ERP power (normalized with the spontaneous activity power) increased especially in delta band during the MI and execution (p = 0.03). After the MP period, MSC values increased for 5 subjects during MI (F = 8.85; p = 0.001) and movement execution (F = 2.37; p = 0.048), in that band. These results suggest the need to evaluate changes in delta band after the PM in new studies.

RESUMEN

Estudos de prática mental com sujeitos novatos apontam sua superioridade à ausência de prática. Entretanto, pré-teste ou familiarização usando prática física podem influenciar o efeito da prática mental. Este estudo investigou os efeitos da prática mental em novatos na tarefa praticada, assim como o posicionamento da prática física em relação à prática mental. Vinte e cinco universitários voluntários praticaram uma tarefa seriada de posicionamento e foram distribuídos em cinco grupos conforme o tipo de prática: física (GPF), mental (GPM), física-mental (GPFM), mental-física (GPMF), e grupo controle (GC) que participou apenas dos testes. Uma Anova não paramétrica aplicada nos testes mostrou superioridade dos grupos com prática física (GPF, GPFM e GPMF) sobre os grupos controle e prática mental. Ao considerar a pequena amostra utilizada, os resultados sugerem que a prática mental em sujeitos novatos depende da prática física para ser efetiva independente de seu posicionamento (antes ou após).


Studies of mental practice with novices pointed out its superiority when compared to no practice at all. However, pre-test as well as familiarization using physical practice can influence the effect from mental practice. This study investigated the effects of mental practice in novice in the practiced task, as well as the location of physical practice in relation to mental practice. Twenty five undergraduate volunteers performed a serial positioning task and they were distributed in five groups in accordance to the type of practice: Physical (GPF), mental (GPM), physical-mental (GPFM), mental-physical (GPMF), and control group (GC) which took part only in tests. A non parametrical Anova applied in tests showed superiority of groups with physical practice (GPF, GPFM, and GPMF) to control and mental practice groups. In considering the small sample, the results suggest that mental practice in novice subjects depends on physical practice to be effective, regardless its location (before or after).


Estudios de práctica mental con sujetos sin experiencia indican su superioridad en comparación a la ausencia de esa la práctica. Entre tanto, pre-test y familiarización usando práctica física pueden influenciar el efecto de la práctica mental. Este estudio investigó los efectos de la práctica mental en novatos en la tarea practicada, bien como el posicionamiento de la práctica física en relación a la práctica mental. Veinticinco universitarios voluntarios practicaron una tarea seriada de posicionamiento y fueron distribuidos en cinco grupos conforme el tipo de práctica: física (GPF), mental (GPM), física-mental (GPFM), grupo mental física (GPMF) y grupo de control (GC) que participó solamente de los testes. Una Anova no paramétrica aplicada en los testes mostró la superioridad de los grupos conforme el tipo de práctica física (GPF, GPFM y GPMF) sobre los grupos de control y de práctica mental. Al considerar que la muestra utilizada fue pequeña, los resultados sugieren que la práctica mental en sujetos novatos depende de la práctica física para ser efectiva, independiente de su posicionamiento (antes o después).

RESUMEN

A prática mental parece contribuir no processo de aprendizagem motora, mas ainda não estão claros os efeitos do posicionamento e da quantidade de prática mental em relação à prática física, sendo este o objetivo do presente estudo. Setenta e dois universitários de ambos os sexos e novatos na tarefa foram distribuídos em seis grupos de prática combinada (física e mental) para a aprendizagem do arremesso do dardo de salão. Na fase de aquisição, os sujeitos realizaram 50 tentativas de prática física e 18, 90 ou 180 tentativas de prática mental (conforme cada grupo) antes ou após a prática física. Dez minutos após a fase de aquisição foram realizados os testes de retenção e transferência. Não foi observada diferença significante entre os grupos nos testes. Os resultados indicaram que a quantidade e o posicionamento da prática mental não influenciaram a aprendizagem do arremesso do dardo de salão.


Mental practice seems to contribute to the motor learning process but it is still not clear the effects of position and amount of mental practice in relation to physical practice, which was the aim of this study. Seventy two undergraduate students of both sexes and novice in the task were assigned in six groups of combined practice (physical and mental) for learning the dart saloon throwing. In acquisition phase, subjects performed 50 trials of physical practice and 18, 90 or 180 trials of mental practice (according to each experimental group) before or after physical practice. Ten minutes after acquisition phase it was performed retention and transfer tests. The results showed that amount and the position of mental practice did not influence dart saloon throwing learning.

RESUMEN

A prática é considerada o fator mais importante em aprendizagem motora e consequentemente organização da prática é o fator mais investigado na área. Existem dois diferentes tipos de prática: mental e física. Prática física é dividida em fracionamento, distribuição e variabilidade de prática. Apesar dos estudos investigarem diferentes tipos de organização da prática separadamente, em situações de ensino e treinamento todas elas interagem na organização da prática. Esta revisão também está organizada da mesma forma, mas ao final foram analisadas as possibilidades de interações.


Practice is considered the most important factor in motor learning and consequently practice schedule is the most investigated factor in the area. There are two different types of practice: mental and physical. Physical practice is divided in fractionated, distributed and variable. Although the studies investigated different types of practice organization separately, in teaching or training situations all of them interact in practice scheduling. This review is organized in a similar way but at the final it was analyzed the possibilities of interactions.

RESUMEN

Objective To explore the effects of mental practice on upper extremity function after stroke. Methods Thirty sub-acute stroke patients were randomly divided into a treatment group ( n=15 ) and a control group (n=15). The patients in the control group were treated with conventional therapy. The patients in the treat-ment group were treated with motor imagery therapy in addition. All patients were assessed using the Fugl-Meyer mo-tor assessment (FMA) and the motor assessment scale (bIAS) before treatment and after 2, 4 and 8 weeks of treat-ment. Results After 2 weeks of treatment, average MAS scores in the treatment group improved significantly com-pared with before treatment, but there was no significant difference between the two groups. After 4 weeks, FMA and MAS scores in the two groups had improved, and the FMA scores in the treatment group were significantly higher than those of the control group. After 8 weeks, the FMA and MAS scores of both groups had further improved significant-ly, but the average FMA and MAS scores in the treatment group were now significantly higher than those in the control group. Conclusions Mental practice can improve the functional performance of the upper extremities of stroke pa-tients.
