Factors shaping joint coordination during multijoint movements were studied using a one-handed ball-catching task. Typically developing (TD) boys between 9 and 12 yr of age, at which catching becomes consistently successful, and boys with developmental coordination disorder (DCD) of the same age participated in the study. The arm was initially stretched down. Catching was performed by flexing t...

This review paper discusses the Reo coordination language in the wider context of its research area. It explains the concept of coordination and argues its significance. Those concepts, models and languages that were of considerable importance in the preliminary research that lead up to the development of Reo, are explained, discussed and evaluated. In particular Linda, Manifold, and Reo itself...

nanoparticles of coordination polymer [co2(pydc)2(h2o)6]n.2n h2o [h2pydc = pyridine-2,5-dicarboxylic acid] have been synthesized by sonochemical method and characterized by elemental analysis, infrared spectroscopy, powder x-ray diffraction, scanning electron microscopy, dls particle size analysis and tga/dta. the structure of single crystalline coordination polymer developed from nanosized coo...

Adolescent rats have been observed to be less sensitive than adults to a number of ethanol effects that may serve as feedback cues to reduce further ethanol intake. Among these findings are a few reports of attenuated sensitivities of adolescents to ethanol-induced motor impairment. The purpose of the present study was to further explore potential age-related differences in ethanol-induced moto...

Introduction: Ionizing radiation is non-surgical treatment of brain tumors and metastases. Preclinical studies have showed main insights into harmful effects of radiation on the nervous system in vivo and in vitro. Cognitive impairment such as progressive memory, executive and attention performance deficits indicates a significant risk for patients experiencing conventional rad...

Three patients with dominant anterior cerebral artery territory infarction demonstrated a severe disturbance of upper limb motor control with impaired bimanual coordination, the "alien hand" sign, and intermanual conflict, in addition to signs of callosal interruption and a transcortical motor aphasia. Recordings of movement-related potentials in one patient showed an attenuated Bereitschaftspo...

Motor disorder refers to neuropsychiatric disorders such as abnormal movements, meaningless repetitive movements, and impairment in acquisition and performance of motor skills. Motor disorder was included as a sub-category of neurodevelopmental disorder chapter in the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) [1]. DSM-5’s motor disorders include tic disorders (T...

Spinocerebellar ataxias (SCAs) are a group of progressive and irreversible neurological diseases affecting gait and movement coordination. Many result from cerebellar degeneration or the impairment of a portion of the neuroaxis that contributes to cerebellar inflow or outflow (Embirucu et al., 2009). In the cerebellum, the dysfunction and death of Purkinje cells, granule cells or interneurons c...

Stroke is defined a sudden neurological impairment resulting from interruption of the blood supply and brain tissue damage. The most common symptom of a stroke is sudden weakness and/or numbness of the face, arms or legs, most often on one side of the body. Other symptoms include: confusion, difficulty speaking or understanding speech; difficulty seeing with one or both eyes; difficulty walking...

The concurrent validity of the Developmental Coordination Disorder Questionnaire (DCDQ) and the McCarron Assessment of Neuromuscular Development (MAND) was investigated in an Australian sample of 38 girls and 91 boys aged 9-12 years (M = 11.15, SD = 0.81). The MAND identified 44 children with motor impairment (MI) and 85 children without MI. The overall decision agreement between the two measur...
