“…Additionally, learning during MI (e.g. Mulder et al, 2004;Kim et al, 2017;Krauetner et al, 2020;Yoxon & Welsh, 2020) may occur when internal models for action are updated using fictive prediction errors (Shadmehr, Smith, & Krakauer, 2010) which are generated as a function of (motor) memory-retrieval (Barron et al, 2020).…”

“…In other words, top-down commands are preserved while bottom-up signals are suppressed during MI, as would be expected under a predictive coding mechanism. Additionally, learning during MI (e.g., Kim et al, 2017; Kraeutner, Eppler, et al, 2020; Mulder et al, 2004; Yoxon & Welsh, 2020) may occur when internal models for action are updated using fictive prediction errors (Shadmehr et al, 2010) which are generated as a function of (motor) memory-retrieval (Barron et al, 2020).…”

The functional equivalence (FE) hypothesis suggests motor imagery (MI) is comparable with the planning stages of action. A strong interpretation of this hypothesis suggests MI can prime subsequent actions in a way that should be indistinguishable from motor preparation (MP). Alternatively, MI could involve more richly informative motor plans than MP, producing different effects on the performance of subsequent actions. Although past research has demonstrated MI can prime action, little research directly compared it to MP, thus the value of strong FE interpretations for understanding MI remains unclear. In the present study, a pre-cueing paradigm was used in four experiments, and congruency effects were compared. Precues could either prepare participants for specific responses (MP condition) or participants should imagine the precued response (MI condition), prior to making their response. Experiment 1 provided first evidence favouring our alternative hypothesis that predicted imagery-primed responses result in larger response priming effects than prepared-responses, meaning that it might involve more richly informative motor plans than preparation for action. Experiment 2 manipulated precueimperative stimulus foreperiods and replicated this effect, showing it to be independent of potential temporal uncertainty differences between the two conditions. Experiment 3 showed the effect is present in both foot and finger responses, and experiment 4 suggested the larger congruency effects in the MI condition cannot be explained by differences in cognitive load. These results suggest that the strong FE hypothesis does not hold. Findings are discussed in line with the predictive processing models of action and MI. Public Significance Statement:Motor imagery is a promising tool for neurorehabilitation, so a better understanding of how motor imagery works is becoming increasingly important as a result. This work shows that motor imagery can influence subsequent action to a greater extent than preparation for action alone. This evidence provides a new and meaningful development to the functional equivalence hypothesis.

“…A previous study showed that MI training led to the development of neuroplasticity (Avanzino et al, 2015 ). Moreover, another study showed that corticospinal activation during MI is positively related to the magnitude of imagery-dependent motor cortical plasticity following MI training (Yoxon and Welsh, 2020 ). In the present study, we observed the changes over time in a short period, only 50 times, but in the future, we will assess long-term changes.…”

The present study aimed to investigate the relationship between motor imagery (MI) assessment (ability and quality) and neurophysiological assessment [transcranial magnetic stimulation (TMS)-induced motor-evoked potentials (MEPs)] during combined MI and action observation (AO; MI + AO). Sixteen subjects completed an MI task playing the piano with both hands, and neurophysiological assessment was performed during the MI task. The Movement Imagery Questionnaire-Revised was adopted to evaluate MI ability, while the visual analogue scale (VAS) was adopted to evaluate MI quality. A TMS pulse was delivered during the MI task, and MEPs were subsequently recorded in the abductor pollicis brevis (APB). We found a significant positive correlation between the VAS score and the TMS-induced MEPs (ρ = 0.497, p < 0.001). These findings suggest that the VAS score could potentially reflect the corticospinal excitability during MI + AO, particularly in complex MI tasks.

“…The ability to perform motor imagery involves the experience of a particular movement or task and depends on working memory, internally influencing motor representation. Therefore, MIT can improve motor performance by activating neuroplasticity in parietal lobes and related areas ( Yoxon and Welsh, 2019 , Yoxon and Welsh, 2020 ). A study applied functional task-oriented MIT in nine individuals and found that MIT could improve upper limbs and motor function of hemiplegic patients and increase visual-motor imagination ability.…”

Stroke, including hemorrhagic and ischemic stroke, refers to the blood supply disorder in the local brain tissue for various reasons (aneurysm, occlusion, etc.). It leads to regional brain circulation imbalance, neurological complications, limb motor dysfunction, aphasia, and depression. As the second-leading cause of death worldwide, stroke poses a significant threat to human life characterized by high mortality, disability, and recurrence. Therefore, the clinician has to care about the symptoms of stroke patients in the acute stage and formulate an effective postoperative rehabilitation plan to facilitate the recovery in patients. We summarize a novel application and update of the rehabilitation therapy in limb motor rehabilitation of stroke patients to provide a potential future stroke rehabilitation strategy.
