This paper reviews selected pertinent literature on the learning and performance of skilled motor acts. Information on normal motor performance is integrated with that on adult apraxia and related to common problems observed in children with developmental dyspraxia. The process of motor skill acquisition is outlined, and aspects of styles of motor organization, modes of control, premovement org...

Information from the external world goes through various transformations. The learning of the original neighbourhood relations of the world using only the transformed information is examined in detail. An approximate representation consists of a nite number of discretizing points and connections between neighbouring points. The goal here is to develop such an approximate representation in a sel...

OBJECTIVE To study the relationship between age and posturography in patients with benign positional paroxysmal vertigo. MATERIAL AND METHODS Prospective study performed in 65 patients with benign positional paroxysmal vertigo (BPPV) in any variant. Sensory Organization Test outcomes were recorded and compared with their equivalents in a control group by means of scatter-plot diagrams and reg...

Sensory Substitution Devices (SSDs) convey visual information through sounds or touch, thus theoretically enabling a form of visual rehabilitation in the blind. However, for clinical use, these devices must provide fine-detailed visual information which was not yet shown for this or other means of visual restoration. To test the possible functional acuity conveyed by such devices, we used the S...

Researchers, therapists, and physicians often use equilibrium score (ES) from the Sensory Organization Test, a key test in the NeuroCom EquiTest System (a dynamic posturography system) to assess stability. ES reflects the overall coordination of the visual, proprioceptive, and vestibular systems for maintaining standing posture. In our earlier article, we proposed a new measure of anterior-post...

OBJECTIVE To examine whether a whole-body vibration (mechanical oscillations) in comparison to a placebo administration leads to better postural control, mobility and balance in patients with multiple sclerosis. DESIGN Double-blind, randomized controlled trial. SETTING Outpatient clinic of a university department of physical medicine and rehabilitation. SUBJECTS Twelve multiple sclerosis ...

objectives: among the most important problems of autistic children are the behavioral disorders due to sensory processing deficiency, which are typically reflected in behaviors such as impulsivity, attention and concentration disorders, undesirable emotional reactions, sensory seeking in the form of stereotype behaviors, self-injury and self-stimulating. the present study aimed at exploring the...
