The Relationship

Objective. To investigate whether motor imagery ability recovers in stroke patients and to see what the relationship is between different types of imagery and motor functioning after stroke.Methods. 12 unilateral stroke patients were measured at 3 and 6 weeks poststroke on 3 mental imagery tasks. Arm-hand function was evaluated using the Utrecht Arm-Hand task and the Brunnström Fugl-Meyer Scale. Age-matched healthy individuals (N=10) were included as controls.Results. Implicit motor imagery ability and visual motor imagery ability improved significantly at 6 weeks compared to 3 weeks poststroke.Conclusion. Our study shows that motor imagery can recover in the first weeks after stroke. This indicates that a group of patients who might not be initially selected for mental practice can, still later in the rehabilitation process, participate in mental practice programs. Moreover, our study shows that mental imagery modalities can be differently affected in individual patients and over time.

Physical Task

Mental imagery is the rehearsal of a physical task mentally, without execution of any physical task. The technique triggers the similar neurons (mirror neurons) of brain as are triggered by physical performance of the task.  Objective: To find correlation between age of stroke patients and mental imagery to improve hand function.Methodology: A sample of 50 patients was selected from DHQ hospital Jhelum. The inclusion criteria were as follows; age 55-75, gender (male and female), and stroke duration more than 12 months. Patients of age below 55 and above 75, patients with parietal stroke were excluded from study. Patients were treated with mental imagery technique for 10 weeks, P<0.05.Results: Both male and females were included in study. Sample consisted of 67% females and 33% male. Mean age of participants was 56.42 + 1.36. WMFT was used as outcome measure. Post treatment mean WMFT score was 57.9. Pearson Correlation was used to find out correlation between age and mental imagery outcome. Conclusions: It was concluded that no correlation is present between age and mental imagery ability of older adult stroke patients. Older adults were benefited with mental imagery technique and a significant improvement in hand function ofstroke patients was found.

The Relationship

The relationship between visual and motor imagery was investigated by administering a battery of visual and motor imagery measures to a sample of 101 men ( n = 49) and women ( n = 52), who ranged in age from 18 to 59 ( M=34.5, SD=12.6). A principal components analysis applied to the correlation matrix indicated four underlying components, which explained 62.9% of the variance. The components were named Implicit Visual Imagery Ability, Self-report of Visual and Motor Imagery, Implicit Motor Imagery Ability, and Explicit Motor Imagery Ability. These results suggested a dissociation between visual and motor imagery although visual and motor imagery were associated as self-reports and there were correlations among particular measures.

The Relationship

Previous research has indicated a potential link between mental imagery and synaesthesia. However, these findings are mainly based on imagery self-report measures and recruitment of self-selected synaesthetes. To avoid issues of self-selection and demand effects, we recruited participants from the general population, rather than synaesthetes specifically, and used colour-picking consistency tests for letters and numbers to assess a ‘synaesthete-like’ experience. Mental imagery ability and mental rotation ability were assessed using both self-report measures and behavioural assessments. Consistency in colour-picking for letters (but not numbers) was predicted by performance on the visual mental imagery task but not by a mental rotation task or self-report measures. Using the consistency score as a proxy measure of grapheme-colour synaesthesia, we provide more evidence for the suggestion that synaesthetic experience is associated with enhanced mental imagery, even when participants are naive to the research topic. This article is part of a discussion meeting issue ‘Bridging senses: novel insights from synaesthesia’.

Over the past 2 decades, much work has been carried out on the use of mental practice through motor imagery for optimizing the retraining of motor function in people with physical disabilities. Although much of the clinical work with mental practice has focused on the retraining of upper-extremity tasks, this article reviews the evidence supporting the potential of motor imagery for retraining gait and tasks involving coordinated lower-limb and body movements. First, motor imagery and mental practice are defined, and evidence from physiological and behavioral studies in healthy individuals supporting the capacity to imagine walking activities through motor imagery is examined. Then the effects of stroke, spinal cord injury, lower-limb amputation, and immobilization on motor imagery ability are discussed. Evidence of brain reorganization in healthy individuals following motor imagery training of dancing and of a foot movement sequence is reviewed, and the effects of mental practice on gait and other tasks involving coordinated lower-limb and body movements in people with stroke and in people with Parkinson disease are examined. Lastly, questions pertaining to clinical assessment of motor imagery ability and training strategies are discussed.
