Theories consider, amongst other factors, motor speech difficulties and linguistic or phonological problems as explanations for the phenomenon of stammering.
The speech production of many individuals with DS is impaired due to several motor speech difficulties stemming from inadequate central motor control and failure in programming, combining, arranging, and sequencing the fine motor movements necessary for proper and exact articulation [ 18].
As a consequence, however, Jill does not deploy the range of multimodal turn construction resources seen in Extract 2, and word finding and motor speech difficulty come to the fore.
However, such sequences have the potential to be problematic precisely because almost all individuals, regardless of aphasia type or severity, have persistent word finding difficulties, and many will also be unable to achieve correct production of a word in the face of a motor speech difficulty, even when a target has been produced for immediate repetition.
Associations between reading problems (yes/no) and developmental milestones, as well as between reading problems and motor or speech difficulties, were tested using regression models.
The apraxia group consisted of 9 males and 5 females, aged 3.9 6.6 years (M = 4.5, SD = 0.8) with confirmed moderate to severe speech difficulties, characterized by focal motor planning deficits (apraxia), in the absence of known neurological disorders, neuromuscular deficits (dysarthria), or hearing problems.
This subject had been followed clinically for many years with AOS prior to enrolment and had a disease duration of 6 years at the time of enrolment into the study; she had isolated motor speech impairment for 5.5 years, only developing eye movement difficulties within the previous 6 months.
The DSM-IV-TR states that "Speech difficulties may be associated with a hearing impairment or other sensory deficit or a speech motor deficit".
Later, speech difficulties develop.
To obtain objective measurements of motor speech characteristics in normal children, using a computer-based motor speech software program.
Abnormally stiff muscles, speech difficulties and vision problems are common.
