“…Motor imagery training, or mental practice, has already been employed to improve balance skills in elderly (Fansler et al, 1985; Hamel and Lajoie, 2005) and in young healthy subjects (Choi et al, 2010), and showed the potential of mental practice as a balance disorder treatment. The present study provides evidence that the effect of motor imagery on postural sway is tightly associated with the postural features of the imagined action.…”

In this study we investigate to what extent the effects of motor imagery on postural sway are constrained by movement features and the subject's imagery ability. Twenty-three subjects were asked to imagine three movements using the kinesthetic modality: rising on tiptoes, whole-body forward reaching, and whole-body lateral reaching. After each task, subjects reported the level of imagery vividness and were subsequently grouped into a HIGH group (scores ≥3, “moderately intense” imagery) or a LOW group (scores ≤2, “mildly intense” imagery). An eyes closed trial was used as a control task. Center of gravity (COG) coordinates were collected, along with surface EMG of the deltoid (medial and anterior portion) and lateral gastrocnemius muscles. COG variability was quantified as the amount of fluctuations in position and velocity in the forward-backward and lateral directions. Changes in COG variability during motor imagery were observed only for the HIGH group. COG variability in the forward-backward direction was increased during the rising on tiptoes imagery, compared with the control task (p = 0.01) and the lateral reaching imagery (p = 0.02). Conversely, COG variability in the lateral direction was higher in rising on tiptoes and lateral reaching imagery than during the control task (p < 0.01); in addition, COG variability was higher during the lateral reaching imagery than in the forward reaching imagery (p = 0.02). EMG analysis revealed no effects of group (p > 0.08) or task (p > 0.46) for any of the tested muscles. In summary, motor imagery influences body sway dynamics in a task-dependent manner, and relies on the subject' imagery ability.

“…Mental practice is a method of learning motor skills and enhancing performance by means of imagining movements in the head without moving the body 5 ) . Recently, mental practice intervention, as a method of learning and enhancing motor skills, have been introduced to such diverse fields as sports psychology, cognitive psychology, and medical science 6 ) . The merits of this intervention are that the patient’s concentration and motivation can be enhanced without regard to time or place, and that training is possible without expensive equipment 7 ) .…”

[Purpose] The purpose of this study was to evaluate the effects of mental practice on stroke patients’ upper extremity function and activities of daily living (ADL). [Subjects and Methods] In this study, 29 stroke patients were randomly assigned to two groups: an experimental group (n=14) and a control group (n=15). The experimental group performed 10 minutes of mental practice once a day, 5 days a week for 2 weeks in combination with conventional rehabilitation therapy. For the control group, general rehabilitation therapy was provided during the same sessions as the experimental group. The Action Research Arm Test (ARAT) and the Fugl-Myer assessment (FMA) were used to measure upper extremity function, and the Modified Bathel Index (MBI) was used to measure daily activity performance. [Results] After the intervention, the mental practice group showed significant improvements in upper extremity function on the affected side and ADL scores compared to the control group. [Conclusion] The results of this study demonstrate mental practice intervention is effective at improving stroke patients’ upper extremity function and daily activity performance. In follow-up studies, securing a greater number of experimental subjects, and evaluation of the intervention’s therapeutic durability are required.

“…During mental practice (MP), physical activities are mentally rehearsed, usually in the absence of voluntary physical movement 1 ) . The same muscular 2 , 3 , 4 ) and neural structures 5 , 6 ) subserve both physical and mental practice, enabling MP to offer similar benefits to rehabilitation in patients with stroke.…”

[Purpose] The purpose of this study was to investigate the effects of the modified constraint-induced therapy (mCIT) combined with mental practice (MP) on patients with chronic stroke. [Subjects] The subjects were 26 patients with chronic stroke. [Methods] Patients were randomly assigned to the mCIMT + MP group or the MP group. All subjects were administered mCIT consisting of (1) therapy emphasizing affected arm use in functional activities 5 days/week for 6 weeks and (2) 4 hours of restraint of the less affected arm 5 days/week. The mCIT + MP subjects received 30-minute MP sessions provided directly after therapy sessions. To compare the two groups, the Action Research Arm Test (ARAT), Fugl-Meyer Assessment of Motor Recovery after stroke (FM), and Korean version of Modified Barthel Index (K-MBI) were performed. [Results] Both groups showed significant improvement in ARAT, FM, and K-MBI after the interventions. Also, there were significant difference in ARAT, FM, and K-MBI between the two groups. [Conclusion] mCIT remains a promising intervention. However, its efficacy appears to be enhanced by use of MP after mCIT clinical sessions.
