Stroke is one of the most common conditions requiring rehabilitation, and its motor impairments are a major cause of permanent disability. Hemiparesis is observed by 80% of the patients after acute stroke. Neuroimaging studies showed that real and imagined movements have similarities regarding brain activation, supplying evidence that those similarities are based on the same process. Within this context, the combination of mental practice (MP) with physical and occupational therapy appears to be a natural complement based on neurorehabilitation concepts. Our study seeks to investigate if MP for stroke rehabilitation of upper limbs is an effective adjunct therapy. PubMed (Medline), ISI knowledge (Institute for Scientific Information) and SciELO (Scientific Electronic Library) were terminated on 20 February 2015. Data were collected on variables as follows: sample size, type of supervision, configuration of mental practice, setting the physical practice (intensity, number of sets and repetitions, duration of contractions, rest interval between sets, weekly and total duration), measures of sensorimotor deficits used in the main studies and significant results. Random effects models were used that take into account the variance within and between studies. Seven articles were selected. As there was no statistically significant difference between the two groups (MP vs control), showed a - 0.6 (95% CI: -1.27 to 0.04), for upper limb motor restoration after stroke. The present meta-analysis concluded that MP is not effective as adjunct therapeutic strategy for upper limb motor restoration after stroke.

Mental practice is an internal reproduction of a motor act (whose intention is to promote learning and improving motor skills). Some studies have shown that other cognitive strategies also increase the strength and muscular resistance in healthy people by the enhancement of the performance during dynamic tasks. Mental training sessions may be primordial to improving muscle strength in different subjects. The aim of this study was to systematically review and meta-analiyze studies that assessed whether mental practice is effective in improving muscular strength. We conducted an electronic-computed search in Pub-Med/Medline and ISI Web of Knowledge, Scielo and manual searchs, searching papers written in English between 1991 and 2014. There were 44 studies in Pub-Med/Medline, 631 in ISI Web of Knowledge, 11 in Scielo and 3 in manual searchs databases. After exclusion of studies for duplicate, unrelated to the topic by title and summary, different samples and methodologies, a meta-analysis of 4 studies was carried out to identify the dose-response relationship. We did not find evidence that mental practice is effective in increasing strength in healthy individuals. There is no evidence that mental practice alone can be effective to induce strength gains or to optimize the training effects.

Motor practice in lucid dreams is a form of mental rehearsal where the dreamer can con-sciously rehearse motor skills in the dream state while being physically asleep (Erlacher, Stumbrys & Schredl, 2011). A previous pilot study showed that practice in lucid dreams can improve subsequent performance (Erlacher & Schredl, 2010). This study aimed to replicated those findings with a different (serial reaction) task (finger-tapping; e.g. Walker et al., 2002) and compare the effectiveness of lucid dream practice not only to physical but also to mental practice in wakefulness.

This research explores the foci, methods and processes of mental training by pianists who are active as performers and teachers. The research is based on the concept of mental training as a solely mental mode of practising. Musician s mental training takes place without an instrument or the physical act of playing. The research seeks answers to questions: 1) What are the foci of a pianist s mental training? 2) How does a pianist carry out the mental training? 3) What does mental training in music entail as a process? The research approach is qualitative, and the materials were gathered from thematic interviews. The aim of practising is always an improved result both in the act of playing and the performance. Mental training by a pianist is collaboration between technical, auditory, visual, kinaesthetic and affective factors. Also interpretation, memory and overcoming stage fright are needed. Technical, cognitive and performance skills are involved. According to the results of this research, mental training is a goal-oriented activity which can have an impact on all of these factors. Without a musical inner ear and its functionality, true musicianship cannot exist. One particular result of this research is the conceptualisation of opening up the inner ear. Auditory exercises and internally playing mental images are essential elements of the mental practice of a musician. Visual images, such as a picture of music notation or a performance event, are the point of focus for musicians who find visual images to be the easiest to realise. When developing technical skills by using mental training, it is important to focus on the technically most difficult sections. It is also necessary to focus on the holistic experiencing of the performance situation. By building on positive energies and strengths, the so-called psyching up may be the most important element in mental training. Based on the results of this research, a synthesis is outlined of the music event as an activity process, built on representations and schemes. Mental training aims at the most ideal possible act of playing and the creation of a musical event; these are achieved by focussing on various mental images produced by the different senses, together with concrete practising. Mental training in sports and in music share common factors. Both modes of practising, mental as well as physical, involve three important elements: planning, realisation and evaluation of the practice. In music, however, the goal is an artistic end result which does not often apply to an athletic event.

OBJECTIVE: To evaluate the effect of altering a single component of a rehabilitation programme (e.g. adding bilateral practice alone) on functional recovery after stroke, defined using a measure of activity.
DATA SOURCES: A search was conducted of Medline/Pubmed, CINAHL and Web of Science.
REVIEW METHODS: Two reviewers independently assessed eligibility. Randomized controlled trials were included if all participants received the same base intervention, and the experimental group experienced alteration of a single component of the training programme. This could be manipulation of an intrinsic component of training (e.g. intensity) or the addition of a discretionary component (e.g. augmented feedback). One reviewer extracted the data and another independently checked a subsample (20%). Quality was appraised according to the PEDro scale.
RESULTS: Thirty-six studies (n = 1724 participants) were included. These evaluated nine training components: mechanical degrees of freedom, intensity of practice, load, practice schedule, augmented feedback, bilateral movements, constraint of the unimpaired limb, mental practice and mirrored-visual feedback. Manipulation of the mechanical degrees of freedom of the trunk during reaching and the addition of mental practice during upper limb training were the only single components found to independently enhance recovery of function after stroke.
CONCLUSION: This review provides limited evidence to support the supposition that altering a single component of a rehabilitation programme realises greater functional recovery for stroke survivors. Further investigations are required to determine the most effective single components of rehabilitation programmes, and the combinations that may enhance functional recovery.

Bimanual actions impose intermanual coordination demands not present during unimanual actions. We investigated the functional neuroanatomical correlates of these coordination demands in motor imagery (MI) of everyday actions using functional magnetic resonance imaging (fMRI). For this, 17 participants imagined unimanual actions with the left and right hand as well as bimanual actions while undergoing fMRI. A univariate fMRI analysis showed no reliable cortical activations specific to bimanual MI, indicating that intermanual coordination demands in MI are not associated with increased neural processing. A functional connectivity analysis based on psychophysiological interactions (PPI), however, revealed marked increases in connectivity between parietal and premotor areas within and between hemispheres. We conclude that in MI of everyday actions intermanual coordination demands are primarily met by changes in connectivity between areas and only moderately, if at all, by changes in the amount of neural activity. These results are the first characterization of the neuroanatomical correlates of bimanual coordination demands in MI. Our findings support the assumed equivalence of overt and imagined actions and highlight the differences between uni- and bimanual actions. The findings extent our understanding of the motor system and may aid the development of clinical neurorehabilitation approaches based on mental practice.

The dance content in Physical Activity Program for third age - PROFIT carried out at UNESP – São Paulo State University has begun in 1997 and is until nowadays a regular physical activity practice to elderly. Since beginnings the dance practitioners work with functional capacities through choreographies, claiming the spatial-time orientation, besides the benefi ts already proved by music uses. Since then, life with dance became a strong way to promote health, trough learning a variety of movements and diff erent rhythms. Today, about 30 elderly advantages besides motor part, dance classes favor body consciousness, mental practice and rhythm. The classes are divided in warm up and stretching phase, principal phase (witch components of functional capacity are stimulated) and fi nalize with cool down phase. The dance program created to physical educations undergraduate students’ opportunities to pedagogical practice and permitted researches development about aging and its relation to physical activity through dance. There are a lot of published results, collaborating with the scientifi c literature about the benefi ts of dance regular practices.

Motor imagery, passive movement, and movement observation have been suggested to activate the sensorimotor system without overt movement. The present study investigated these three covert movement modes together with overt movement in a within-subject design to allow for a fine-grained comparison of their abilities in activating the sensorimotor system, i.e. premotor, primary motor, and somatosensory cortices. For this, 21 healthy volunteers underwent functional magnetic resonance imaging (fMRI). In addition we explored the abilities of the different covert movement modes in activating the sensorimotor system in a pilot study of 5 stroke patients suffering from chronic severe hemiparesis. Results demonstrated that while all covert movement modes activated sensorimotor areas, there were profound differences between modes and between healthy volunteers and patients. In healthy volunteers, the pattern of neural activation in overt execution was best resembled by passive movement, followed by motor imagery, and lastly by movement observation. In patients, attempted overt execution was best resembled by motor imagery, followed by passive movement and lastly by movement observation. Our results indicate that for severely hemiparetic stroke patients motor imagery may be the preferred way to activate the sensorimotor system without overt behavior. In addition, the clear differences between the covert movement modes point to the need for within-subject comparisons. (C) 2012 Elsevier Inc. All rights reserved.

Bioinformational theory has been proposed by Lang (1979a), who suggests that mental images can be understood as products of the brain's information processing capacity. Imagery involves activation of a network of propositionally coded information stored in long-term memory. Propositions concerning physiological and behavioral responses provide a prototype for overt behavior. Processing of response information is associated with somatovisceral arousal. The theory has implications for imagery rehearsal in sport psychology and can account for a variety of findings in the mental practice literature. Hypotheses drawn from bioinformational theory were tested. College athletes imagined four scenes during which their heart rates were recorded. Subjects tended to show increases in heart rate when imagining scenes with which they had personal experience and which would involve cardiovascular activation if experienced in real life. Nonsignificant heart rate changes were found when the scene involved activation but was one with which subjects did not have personal experience.

This paper highlights challenges in implementing mental health policy at a service delivery level. It describes an attempt to foster greater application of recovery-orientated principles and practices within mental health services. Notwithstanding a highly supportive policy environment, strong support from service administrators, and an enthusiastic staff response to training, application of the training and support tools was weaker than anticipated. This paper evaluates the dissemination trial against key elements to promote sustained adoption of innovations. Organisational and procedural changes are required before mental health policies are systematically implemented in practice.
