BackgroundMotor imagery is considered as a promising therapeutic tool for rehabilitation of motor planning problems in patients with cerebral palsy. However motor planning problems may lead to poor motor imagery ability.AimThe aim of this functional magnetic resonance imaging study was to examine and compare brain activation following motor imagery tasks in patients with hemiplegic cerebral palsy with left or right early brain lesions. We tested also the influence of the side of imagined hand movement.MethodTwenty patients with clinical hemiplegic cerebral palsy (sixteen males, mean age 12 years and 10 months, aged 6 years 10 months to 20 years 10 months) participated in this study. Using block design, brain activations following motor imagery of a simple opening-closing hand movement performed by either the paretic or nonparetic hand was examined.ResultsDuring motor imagery tasks, patients with early right brain damages activated bilateral fronto-parietal network that comprise most of the nodes of the network well described in healthy subjects. Inversely, in patients with left early brain lesion brain activation following motor imagery tasks was reduced, compared to patients with right brain lesions. We found also a weak influence of the side of imagined hand movement.ConclusionDecreased activations following motor imagery in patients with right unilateral cerebral palsy highlight the dominance of the left hemisphere during motor imagery tasks. This study gives neuronal substrate to propose motor imagery tasks in unilateral cerebral palsy rehabilitation at least for patients with right brain lesions.

“…There was substantial variability in age, gender, clinical characteristics, level of sensory deficits, and type of lesion, as well as in MRI parameters, activation tasks, and statistical methods. Despite that, all studies showed similar results—predominant compensation through ipsilesional reorganization of the sensory function: 74 of all 77 patients showed activation only in the ipsilesional hemisphere during sensory tasks independent of lesional type and activation method. Only 3 patients from the earliest study displayed only contralesional activation.…”

“…Simple passive movement of the paretic hand (without video‐guidance) activated more strongly ipsilesional precentral and postcentral gyri (M1 and S1), ipsilesional SMA‐proper, ipsilesional thalamus, and ipsilesional Rolandic operculum and contralesional (ipsilateral to the hand) cerebellum, than video‐guided passive movement. On the other hand, the latter task evoked additional activation of the posterior cortical regions (engaged in encoding concomitant visuospatial and visuomotor information) as well as of frontal brain regions (involved in motor planning) …”

“…The importance of the ipsilateral (to the stimulated hand) red nucleus and lateral cerebellum in sensory processing surpasses their role of motor coordination. They are activated by purely sensory stimuli, even in the absence of the opportunity to coordinate finger movements or to use the sensory cues to guide movement …”
