“…According to certain theories, motor imageryor imagined motions-contributes significantly to the process of planning movements and is a requirement for motor planning. Similar brain activation patterns during actual movements and imagined motions have been shown in an increasing number of investigations utilizing functional magnetic resonance imaging (19) .…”

Background: Children with hemiparetic cerebral palsy experience fine motor ability and cognitive deficits. The development of fine motor skills is a necessary part of emotional, social, and cognitive growth. Objective: The aim of the current work was to study the correlation between fine motor skills and cognitive abilities in children with hemiparetic cerebral palsy. Subjects and methods: This cross-sectional study included a total of 85 children with spastic hemiplegia of both sexes and aged from 6 to 8 years, recruited from the Outpatient Clinic, Faculty of Physical Therapy, Cairo University. Fine motor abilities were assessed by Quality of Upper Extremity Skills Test (QUEST) whereas; Cognitive abilities were assessed using RehaCom system. Results: The correlation between Fine motor skills and cognitive abilities measurements was weak positive significant correlation with reaction control (r = 0.260, p = 0.016), moderate positive significant correlation with working speed (r = 0.351, p = 0.001) and was strong positive significant correlation with working memory (r = 0.786, p = 0.001). The correlation between fine motor skills and other cognitive abilities was weak negative non-significant correlation with reaction speed (r = -0.110, p = 0.316) and with attention (r = -0.092, p = 0.403); and was weak positive non-significant correlation with neglect hemianopia (r = 0.124, p = 0.259) and with logical reasoning (r = 0.031, p = 0.778). Conclusion:It could be concluded that there are correlations between fine motor skills and cognitive abilities in children with hemiparetic cerebral palsy.

“…TMS is currently the chosen method for stimulating motor activity in human brain due to its non-invasive and painless nature. Since the mapping accuracy of a single pulse TMS (spTMS) for determining motor area is currently debatable, its reliability is not certain and should be further investigated [4,14,21,22,26].…”

Background: The functional reorganization of motor functions is a sign of adaptive brain plasticity to brain damage and understanding its mechanisms may be a key role to many treatment models for brain damage in childhood and even in adults. Our aim is to show an electrophysiological evidence of brain plasticity regarding motor functions in early brain damaged patients. Methods: We retrospectively analyzed four patients with some extremity motor functions shifting to unusual brain areas who were diagnosed with childhood epilepsy and underwent epilepsy surgery. We analyzed their clinical and surgical data particularly including intraoperative neuromonitorization (IONM) results. Results: Patients’ preoperative data showed some motor representation of extremities was located somewhere else than the expected brain areas due to perinatal damage. In first patient right hand presentation was shifted to the right hemisphere and in second patient right hand was represented on both hemispheres. In the remaining two patients, all the motor functions of epileptogenic hemisphere were shifted to the contralateral side. IONM proved the neuroplasticity of the patients with previously crossed motor functions and was in line with preoperative functional Magnetic Resonance Imaging data. Conclusion: Brain plasticity can alter the motor reorganization of the healthy hemisphere by taking upon the functions of the pathological hemisphere.

“…If disruption of plan encoding reduces the benefits of mental practice without eliminating them completely, this would evidence the idea of multiple mechanisms involved in motor imagery, such as the PCM + MET fusion model proposed above. Existing work has examined how TMS inhibition of various motor-related brain regions impacts motor imagery performance (see Chepurova et al, 2022 for a review), yielding preliminary evidence that motor imagery is not impaired by disrupting encoding-related regions (specifically the primary motor cortex, Kraeutner et al, 2017 ). However, additional research with other relevant brain regions and a wider range of motor tasks is needed before any definitive conclusions can be drawn.…”

Over the past few decades, researchers have become interested in the mechanisms behind motor imagery (i.e., the mental rehearsal of action). During this time several theories of motor imagery have been proposed, offering diverging accounts of the processes responsible for motor imagery and its neural overlap with movement. In this review, we summarize the core claims of five contemporary theories of motor imagery: motor simulation theory, motor emulation theory, the motor-cognitive model, the perceptual-cognitive model, and the effects imagery model. Afterwards, we identify the key testable differences between them as well as their various points of overlap. Finally, we discuss potential future directions for theories of motor imagery.
