Abstract
Purpose/aim: Motor imagery (MI) is the mental representation of a movement without engaging its actual execution. MI shares neuroanatomical correlates with brain motor networks. Neurologic disorders affecting motor skills, such as stroke, have been related to impairments in MI. A descriptive review was conducted to explore the effects of stroke on MI ability and its background mechanisms.
Materials and Methods: We searched on PubMed and Web of Science databases and screening references of included studies and review articles for additional citations.
Results: On a total of 885 studies, only 15 articles met inclusion criteria. Results suggested that MI is impaired after stroke, in implicit and explicit abilities. Impairments in mental chronometry as well as in accuracy and reaction times were observed.
Conclusions: Neuroimaging findings confirmed a brain reorganization after a stroke and a compensatory over-usage of contralesional hemisphere was highlighted.
