BACKGROUND/PURPOSE Dysphagia may worsen due to fatigue of the infrahyoid and suprahyoid muscle groups as a result of repetitive swallowing during a meal. We investigated the hypothesis that meal consumption may reduce tongue strength and endurance in older adults (OAs). METHODS Tongue-palate pressure, oral diadochokinesis, repetitive saliva swallowing, and surface electromyography activity be...

Acoustic analyses of sentence utterances noted slowed speech tempo, concomitant with a tendency towards syllable isochrony, in patients with impaired vocal tract control due to ataxic disorders. Furthermore, kinematic measurements revealed decreased maximum velocity of articulatory orofacial gestures with respect to a given movement amplitude. Syllable lengthening seems to develop into a platea...

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...

PURPOSE The aim of the present study was to investigate whether previous long-term exposure to manganese (Mn) via inhalation of welding fumes can cause persistent impairment in neuromotor function even long after cessation of exposure. METHODS Quantitative tests of tremor, motor speed, manual dexterity, diadochokinesis, eye-hand coordination and postural stability were administered to 17 reti...

In individuals with autism or autism-spectrum-disorder (ASD), conflicting results have been reported regarding the processing of biological motion tasks. As biological motion perception and recognition might be related to impaired imitation, gross motor skills and autism specific psychopathology in individuals with ASD, we performed a functional MRI study on biological motion perception in a sa...

IMPORTANCE Although voice has been studied extensively in children who use cochlear implants (CIs), speech production has not been studied in this population using the Motor Speech Profile. Whether children who receive CIs gain normal speech production abilities is unknown. OBJECTIVE To assess speech and articulation in deaf, long-term CI users who had undergone early unilateral cochlear impl...

OBJECTIVE To investigate in patients with essential tremor (ET) treated with thalamic/subthalamic deep brain stimulation (DBS) whether stimulation-induced dysarthria (SID) can be diminished by individualized current-shaping with interleaving stimulation (cs-ILS) while maintaining tremor suppression (TS). METHODS Of 26 patients screened, 10 reported SID and were invited for testing. TS was ass...

Kumar et al investigated the magnetic resonance findings of the brain and spinal cord in a large series of patients with adult-onset adrenoleukodystrophy (ALD), and described tract involvement in the corticospinal, spinothalamic, visual, and auditory pathways (1). Some authors have noticed tract demy-elination involving the cerebellar peduncles (2,3). We describe a case of adult-onset ALD with ...
