The motor programs stored in the procedural memory systems allow the generation of motor mental images without the need for an external stimulus, although it has been demonstrated that providing visual information, prior to a task of imagination, facilitates it and causes a greater neurophysiological activity than if it were done in an isolated manner. Some studies have shown that in the short term, in complex motor tasks of foot and hand in a coordinated manner, the action observation training provokes a greater motor learning compared to the motor imagery strategy.
However, these studies have only assessed short-term memory immediately after the intervention. No study has so far evaluated these improvements in motor learning through action observation training and motor imagery on consecutive days, nor has it been evaluated with short to medium-term follow-up.
It is therefore that there is a lack in the current scientific literature regarding which isolated method, without physical practice, of mental practice on motor learning is the most effective when exposed both on consecutive days, as well as to short-medium-term follow-up.

Experimental: Motor imagery
A group of healthy subjects who meet the inclusion and exclusion criteria established for the study to which a first-person kinesthetic motor imagery training will be conducted on a sequence of manual motor gestures of increasing complexity for four consecutive days. The tasks of motor imagery will be 2 series of 30 seconds for each of the 12 manual positions to remember
Behavioral: Motor imagery
Two series of 30 seconds training of motor imagery in each manual engine gesture
Experimental: Action observation
A group of healthy subjects who meet the inclusion and exclusion criteria established for the study to which a first-personaction observation training will be conducted on a sequence of manual motor gestures of increasing complexity for four consecutive days. The tasks of action observation will be 2 series of 30 seconds for each of the 12 manual positions to remember in video format.
Behavioral: Action observation
Two series of 30 seconds training of action observation training in video format in each manual engine gesture
Placebo Comparator: Placebo group
A group of healthy subjects who meet the inclusion and exclusion criteria established for the study to which an imagery training and placebo observation, inspired by a rural landscape, will be given for four consecutive days. This group will carry out the observation and imagination of a landscape during 2 series of 30 seconds for each manual motor sequence to remember.
Behavioral: Placebo intervention
Two series of 30 seconds of observation and imagination of a landscape during for each manual motor sequence
- Percentage of successes in finger positions [ Time Frame: changes in the success rates at the end of the intervention, 7 days, 1 month and 4 months after the end of the intervention ]During the measurements, the percentage of hits and errors achieved in each hand position in each of the manual engine sequences will be evaluated.
- Execution time [ Time Frame: changes in the success rates at the end of the intervention, 7 days, 1 month and 4 months after the end of the intervention ]During each measurement, the time required for each participant to place their hands will be recorded.
- Visual and Kinesthetic Motor Imagery Ability [ Time Frame: Pre-intervention ]Visual and Kinesthetic Motor Imagery Ability will be measured with MIQ-R Questionnaire. MIQ-R has 4 movements repeated in two subscales, a visual and a kinaesthetic one. Additionally, a score between 1 and 7 is assigned, with 1 representing difficulty in picturing the motor image or difficulty in feeling the movement previously made, and 7 representing the maximum ease. A modification was made in the MIQ-R. Items 2 and 5, in which a small jump is made, were changed by standing on tiptoe. The internal consistencies of the MIQ-R have been consistently adequate with Cronbach's α coefficients ranging above 0.84 for the total scale, 0.80 for de visual subscale and 0.84 for the kinesthetic subscale.
- Mental Chronometry [ Time Frame: Pre-intervention ]Mental chronometry evaluation was also used to measure the subject's motor imagery ability. Using a stopwatch, the time spent for performing each MIQ-R task was recorded. Time recorded corresponds to the interval between the command to start the task, given by the evaluator, and the verbal response of conclusion of the task, given by the subject. Mental chronometry is a reliable behavioral task that has previously been employed to collect an objective measure of MI ability
- The degree of physical activity [ Time Frame: Pre-intervention ]The degree of physical activity was objectified through the The International Physical Activity Questionnaire questionnaire, which allows the subjects to be divided into three groups according to their level of activity, which can be high, moderate, and low or inactive
- Laterality task [ Time Frame: Pre-intervention ]With the task of recognition of the hand's laterality, two aspects will be evaluated: first, the precision (percentage of correct answers) of the discrimination of the laterality which is the capacity to recognize if a part of the body belongs to the right or left hemicorpse and second, the response time that the participants use in the task of discrimination or cognitive judgment. The app designed and developed by the NOI group will be used.
- Memory Operation Questionnaire [ Time Frame: Pre-intervention ]The allows a cognitive evaluation of everyday memory failures. The questionnaire contains four subscales: daily memory, text recall, past memories and mnemonic strategies. The memory functioning questionnaire has adequate psychometric properties of validity and reliability obtained. An acceptable internal consistency was obtained, with a Cronbach alpha coefficient of the total scale of 0.818 memory operation questionnaire
