“…However, it is difficult to control and identify the imagery of the patients explicitly. Since the HMRT has the potential to elicit the participant’s own hand movement implicitly, it has been applied in rehabilitation treatment (Moseley, 2004; Polli et al, 2017; Dilek et al, 2018). In order to do this, it must be guaranteed that the MI is induced during HMRT.…”

A hand mental rotation task (HMRT) is a task wherein a person judges whether an image of a rotated hand is of the right or left hand. Two performance strategies are expected to come into play when performing these tasks: a visual imagery (VI) strategy, in which an image is mentally rotated, and a motor imagery (MI) strategy, in which the movement of a person’s own hand is simulated. Although elderly people generally take some time to perform these tasks, ability differs greatly between individuals. The present study hypothesizes that there is a relationship between differences in task performance strategy and performance ability, and it compares performance strategy among elderly people divided into groups with a short mental rotation time and a long mental rotation time. In response to images of the palm, both groups displayed a medial-lateral effect in which responses were faster for images where the third finger was rotated toward the midline of the body than images rotated in the opposite direction, and we inferred that an MI strategy was primarily employed. Meanwhile, in response to images of the back of the hand, a medial-lateral effect was also observed in the group with a long mental rotation time and not in the group with the shortest mental rotation time (VI strategy). These results suggest that different strategies for performing HMRT task are used by elderly people with a short mental rotation time and those with a long mental rotation time.

“…Also, the literature reports that GMI technique, of which implicit imagery is a part, helped in the improvement of peripheral conditions like flexor tendon injuries, distal end radius fractures by retraining the cortical disorganization. 16,17 These injuries constituted a major part of our study group from which it is further hypothesized that implicit imagery, in this study is impaired due to cortical changes as GMI works on the principle of retraining the cortical disruption that occurs in such chronic conditions; however this is an assumption, and further fMRI studies to explore the cause of implicit imagery impairment are needed to prove this hypothesis. 18…”

Introduction: Implicit motor imagery is the first step of graded motor imagery technique, which is known to be impaired in chronic pain conditions. However, there is a paucity of literature investigating implicit imagery in peripheral conditions like chronic complex hand injuries and its relation with upper extremity function. Method: Thirty participants in the study group and 30 in the control group were included. Implicit imagery was assessed using hand laterality recognition task where participants identified 48 different hand images, as left-or righthand images. Accuracy and response time were calculated and compared between the two groups. The Disabilities of Arm, Shoulder and Hand (DASH) questionnaire was used to assess the upper extremity functional level and correlated with implicit imagery as secondary objective. Results: Hand injured patients had a 76.18% accuracy and 2.30 seconds/card response time. There was a statistically significant difference in accuracy (p < 0.0001) and response time (p ¼ 0.0066) between study group and control group. Disability level assessed by DASH was 40.5 and had no correlation with accuracy (r ¼ 0.004; 95% CI: 0.3663-0.3736) and response time (r ¼ 0.099; 95% CI: 0.2804-0.4531). Conclusion: Implicit imagery was impaired in chronic complex hand injured patients and it had no relation with upper extremity functional level.

“…An online surgical training course, where trainees conducted a short amount of imagery, regularly and at their convenience, would fit these requirements. Indeed, there were 7 12,27,30,52,55,60,74 studies in which subjects were instructed to perform MI independently at home and record their progress. In the study by Louridas et al, 12 surgical trainees were given 7 days to perform MI at home and had follow-up calls and feedback.…”

Objective. Motor imagery (MI) is widely used to improve technical skills in sports and has been proven to be effective in neurorehabilitation and surgical education. This review aims to identify the key characteristics of MI protocols for implementation into surgical curricula. Design. This study is a systematic review and meta-analysis. PubMed, MEDLINE, Embase and PsycINFO databases were systematically searched. The primary outcome was the impact of MI training on measured outcomes, and secondary outcomes were study population, MI intervention characteristics, study primary outcome measure and subject rating of MI ability (systematic review registration: PROSPERO CRD42019121895). Results. 456 records were screened, 60 full texts randomising 2251 participants were reviewed and 39 studies were included in meta-analysis. MI was associated with improved outcome in 35/60 studies, and pooled analysis also showed improved outcome on all studies with a standardised mean difference of .39 (95% CI: .12, .67, P = .005). In studies where MI groups showed improved outcomes, the median duration of training was 24 days (mode 42 days), and the median duration of each individual MI session was 30 minutes (range <1 minute-120 minutes). Conclusions. MI training protocols for use in surgical education could have the following characteristics: MI training delivered in parallel to existing surgical training, in a flexible format; inclusion of a brief period of relaxation, followed by several sets of repetitions of MI and a refocusing period. This is a step towards the development of a surgical MI training programme, as a low-cost, low-risk tool to enhance practical skills.
