Previous studies have reported a similar duration for movement execution (real movement) and its internal simulation with motor imagery (virtual movement). The present work has studied the real movement-virtual movement relationship for complex sequences of finger movements after different acute and chronic brain lesions and after a long-lasting restriction of right-hand movements. Age, hand-mo...

BACKGROUND Visuo-motor coordination (VMC) requires normal cognitive executive functionality, an ability to transform visual inputs into movement plans and motor-execution skills, all of which are known to be impaired in Parkinson's disease (PD). Not surprisingly, a VMC deficit in PD is well documented. Still, it is not known how this deficit relates to motor symptoms that are assessed routinely...

Background: Aromatic L-amino acid decarboxylase (AADC) deficiency is caused by mutations in the dopa gene leading to reduced AADC enzyme activity; it characterized motor impairments and inability attain developmental milestones.

BACKGROUND Persisting neurological and cognitive impairments are common after cerebral malaria. Although risk factors for gross deficits on discharge have been described, few studies have examined those associated with persistent impairments. METHODS The risk factors for impairments following cerebral malaria were determined by examining hospital records of 143 children aged 6-9 years, previo...

Developmental dyslexia is a heterogeneous syndrome with a phonological core deficit and frequent association with other developmental disorders. Controversies exist about the influence of motor difficulties frequently encountered in dyslexia. According to different theoretical approaches, these motor impairments would reflect either a frequent co-morbid entity or a cerebellar dysfunction that c...

BACKGROUND Alcohol-related neuropsychological impairments mainly affect episodic memory, working memory, and visuospatial abilities, as well as executive and motor functioning. These impairments can prevent alcoholic patients (ALs) early in abstinence from benefiting fully from treatment and reduce their ability to remain abstinent. A neuropsychological assessment seems essential for making the...

Although autism is diagnosed according to three core features of social deficits, communication impairments, and repetitive or stereotyped behaviors, other behavioral features such as sensory and motor impairments are present in more than 70% of individuals with autism spectrum disorders (ASD). Exposure of rat pups to the teratogen valproate during sensitive periods of brain development has bee...

Parkinson’s disease (PD) is a progressive neurodegenerative disorder that impairs motor function. Patients with PD display motor symptoms including bradykinesia, akinesia, rigidity, resting tremor, and postural instability. In addition, recent studies have found early non-motor symptoms in patients with PD including olfactory impairments, gastrointestinal dysfunction, sleep disturbances, anxiet...

The purpose of this study was to examine the relationship between motor skill impairments and motor imagery ability in children with autism spectrum disorders (ASD). The participants were 19 children with ASD, aged 7 16 years. We conducted two tasks: movement assessment battery for children-2 (MABC-2) and hand rotation task. The MABC-2 is a motor test that can assess total motor ability, and th...

BACKGROUND: Mental practice (MP) is a mind-body technique in which physical movements are cognitively rehearsed. It has shown efficacy in reducing the severity of a number of neurological impairments. AIMS: In the present review, we highlight recent developments in MP research, and the basis for MP use after stroke-induced motor speech disorders. MAIN CONTRIBUTION: In this review, we: (a) pro...
