Background: The first purpose of this study was to investigate the rate of oral and laryngeal Diadochokinesis (DDK) in Multiple Sclerosis (MS) patients in comparison with healthy people. The second goal was to determine if DDK rate has any relationship with the disease progression. Methods: In this cross-sectional study, two groups were enroll...

Objectives: The present research aimed to identify the assessment and treatment processes implemented by Iranian speech-language pathologists (SLPs) for CAS and to investigate the possibility of impact of their knowledge level and years of experience on their choice of assessment and treatment. Methods: A cross-sectional method using survey design was employed to obtain a sample of 260 SLPs w...

BACKGROUND One of the limiting factors for early hospital discharge in preterm infants is their inability to feed sufficiently to obtain consistent weight gain. Therefore, feeding difficulty is one of the most significant issues with which a preterm infant is faced. OBJECTIVES The purpose of this study was to examine the effect of oral sensory motor stimulation on feeding performance, length ...

BACKGROUND We previously developed a rat trigeminal motor neuron axotomy model involving masseter and temporal muscle resection to study pathological changes of the central nucleus after peripheral nerve injury caused by oral surgery. Because motor neurons are reported to be more vulnerable to axotomy in mice than rats, we compared the degeneration process of the trigeminal motor nucleus in the...

We present a computational model that learns a coupling between motor parameters and their sensory consequences in vocal production during a babbling phase. Based on the coupling, preferred motor parameters and prototypically perceived sounds develop concurrently. Exposure to an ambient language modifies perception to coincide with the sounds from the language. The model develops motor mirror n...

One classical argument in favor of a functional role of the motor system in speech perception comes from the close-shadowing task in which a subject has to identify and to repeat as quickly as possible an auditory speech stimulus. The fact that close-shadowing can occur very rapidly and much faster than manual identification of the speech target is taken to suggest that perceptually induced spe...

Oral levodopa remains the most effective symptomatic drug for Parkinson’s disease (PD); however, its long-term use is limited by the emergence of motor fluctuations and involuntary movements, particularly in young-onset patients. A growing number of preclinical and clinical studies suggest that non-physiological pulsatile stimulation of striatal dopamine (DA) receptors induced by the use of sho...

Researchers in cognitive neuroscience have become increasingly interested in how different aspects of tool use are integrated and represented by the brain. Comparatively less attention has been directed toward tool use actions themselves and how effective tool use behaviors are coordinated. In response, we take this opportunity to consider the mechanical principles of tool use actions and their...

________________________________________________________________________________________________________ When nasal is more than nasal: Oral articulation of French nasal vowels Lingual and labial articulations of oral and nasal vowels of three Metropolitan French (FM) speakers were recorded using an EMA system. Inter-speaker variation in these oral articulations suggest that the role of motor e...

Application of oral fast release amantadine and levodopa may induce an improvement of motor symptoms in patients with Parkinson's disease (PD). The objective of this trial was to investigate the clinical efficacy of a fast release amantadine sulfate formulation on simple and complex movement performance and putative relations to the pharmacokinetic behavior in PD patients. We challenged two coh...
