Developmental coordination disorders (DCD) affect approximately 6% of school aged children and significantly impair their activities of daily living and their academic performance. These impairments are not explicable by age, IQ or neurological condition.1,2 Some studies suggest that deficits in motor coordination among children with DCD could be related to sensory processing difficulties (SPD)...

The central pattern generator for heartbeat in medicinal leeches constitutes seven identified pairs of segmental heart interneurons. Four identified pairs of heart interneurons make a staggered pattern of inhibitory synaptic connections with segmental heart motor neurons. Using extracellular recording from multiple interneurons in the network in 56 isolated nerve cords, we show that this patter...

Social motor coordination remains a relatively overlooked dimension of social behavior in children with ASD. One reason for the lack of research is that the motion tracking equipment historically used for recording body movements of children during social interaction has been very costly, as well as cumbersome and impractical. Here we examined whether two low-cost motion-tracking options can be...

OBJECTIVE This study aimed to determine the ability of different measures of adiposity to discriminate between low/high motor coordination and to evaluate the relationship between different measures of adiposity and motor coordination. METHODS This study included 596 elementary school children aged 9 to 12 years (218 females - 47.1%). Weight, height, and waist circumference were objectively m...

the purpose of this study was to investigate the effects of body mass index on fundamental motor skills performance in 7-8-year-old boys in hamedan. forthis purpose, 72 elementary students were selected via cluster randomization from the elementary schools of hamedan and divided into three groups: fat, normal, and thin according to percentile diagram. then, tgmd-2 was performed by children and ...

Lurcher mutant mice represent a model of olivocerebellar degeneration. They suffer from cerebellar ataxia and deterioration of cognitive functions. The aim of the work was to study the effect of repetitive enforced motor training on spatial learning ability and motor coordination in adult Lurcher mutant mice of the C57BI strain. Experimental mice were trained repetitively on a rotarod. Control ...

It is well known that environmental stimulation is important for the proper development of sensory function. The vestibular system senses gravitational acceleration and then alters cardiovascular and motor functions through reflex pathways. The development of vestibular-mediated cardiovascular and motor functions may depend on the gravitational environment present at birth and during subsequent...

Evidence suggests that the nervous system controls motor tasks using a low-dimensional modular organization of muscle activation. However, it is not clear if such an organization applies to coordination of human walking, nor how nervous system injury may alter the organization of motor modules and their biomechanical outputs. We first tested the hypothesis that muscle activation patterns during...

The cellular and network basis for most vertebrate locomotor central pattern generators (CPGs) is incompletely characterized, but organizational models based on known CPG architectures have been proposed. Segmental models propose that each spinal segment contains a circuit that controls local coordination and sends longer projections to coordinate activity between segments. Unsegmented/continuo...
