As treatment progresses those times are used to practise skills to lower demands and reinforce capacities according to clinician guidance blood pressure band purchase labetalol us. Typical treatment sessions involve the clinician observing the parent playing and talking with the child heart attack music video purchase labetalol with a visa, discussing progress during the previous week arteria pancreatica magna cheap labetalol 100 mg with mastercard, and having the parent demonstrate treatment procedures that were used during the previous week arteria occipital purchase cheap labetalol on-line. The clinician then outlines changes to clinical procedures for use during the coming week hypertension kidney group 08755 order labetalol 100 mg with mastercard, demonstrates them to the parent 01 heart attackm4a purchase labetalol online from canada, and has the parent attempt the procedures. The 37 program criteria are the child has normal-fluent speech (very young children for approximately six weeks and older children [aged 4 1/2 -6] approximately 3-4 months) or exhibits only incidental disfluencies that are minimally abnormal (occasional repetitions with usually one iteration). The parents implement a fluency enhancing environment or the speech therapist/fluency expert judges that the parents can maintain the rest of the modification on their own. The treatment manuals show that more than 60 therapy strategies are involved with each of the treatments. Data about the matter are limited, but one of the clinical trials of Palin Parent- 32 Child Interaction therapy suggested that, in practice, the treatment might be simpler than it appears at face value. In that trial, from four to six therapy strategies were chosen for each of the six families in the trial. Issues with the underpinning theoretical model A treatment based on a theoretical model of the nature of stuttering will be questionable if the model itself is questionable. As outlined during Lecture Three, there are grounds to argue that multifactorial models of early stuttering are indeed questionable, and consequently they have received considerable criticism. Also, the latter treatment involves a speech motor training program in the event that a child fails an oral motor assessment. The Westmead Program An old technique this treatment is currently in early developmental stages at the Australian Stuttering Research Centre, Sydney, Australia. It uses the well-known rhythm effect, or what is often called syllable-timed speech. As described during Lecture One, this is a fluency inducing condition that seems to have been used to treat stuttering centuries ago. It appears that the earliest documented modern use of this as a stuttering 41,42 treatment occurred during the 1930s. To summarise, when adults who stutter speak while they are saying each syllable to a rhythmic beat, either aided by a metronome or not, they stop stuttering. Early application to pre-schoolers During the early 1980s some researchers looked for clinically useful effects when pre-school children 43 spoke in rhythm. Then, during each session, the children spoke in a sequence from three single-syllable phrases, to four-six syllable phrases, then conversational speech. The researchers concluded that the treatment was worthy of further investigation, but no subsequent reports were published. The experimenter played a metronome in the background with a group of 20 children. Half of them were instructed to talk to the beat of the metronome and the other half received no instruction. Predictably, the children who were instructed to talk rhythmically did not stutter. But surprisingly, the study showed that the children who received no instruction also showed a significant treatment effect. In other words, the children showed a treatment effect from rhythmic stimulation without being instructed to speak that way. That was certainly most suggestive of clinical value for syllable-timed speech with children. The aim is to achieve normal speech rate and speech that does not sound unnatural in any way. Parents prompt their children to use syllable-timed speech occasionally between these practice sessions. There are no set rules for how often these daily therapy activities should happen; the clinician makes a judgement for each child and family. Parents visit the clinic each week As with all evidence-based early stuttering treatments, parents and children visit the clinic each week. During each weekly visit the clinician teaches parents how to do the treatment and ensures that it is being done properly. Treatment goals during Stage 1 and Stage 2 As with the Lidcombe Program, Westmead Program treatment criteria are no stuttering or nearly no stuttering for a long time. As with the Lidcombe Program, Stage 2 of the treatment is sometimes referred to as maintenance. During this period the parent and child establish a routine where syllable-timed speech is practiced each day. The clinician teaches parents, where necessary, to modify utterance length and grammatical complexity to make syllable-timed speech easier to learn. Generally, children learn to do the speech pattern quickly and are able to do it during conversation during the first few sessions. At this time the clinician directs the parent to have the child attempt it during conversations between practice sessions. As with the Lidcombe Program, it is critical to be sure that parents are doing what the clinician intends. Stage 2 When children attain the treatment criteria, Stage 2 begins, and the family makes visits to the clinic less frequently during a period of 1 year. During Stage 2 parents are instructed to gradually stop doing the practice sessions each day. In the event that during a Stage 2 clinic visit the child does not meet treatment criteria, the clinician has the option of either stopping progress through Stage 2 while the problem is resolved, or to return the child to Stage 1 to re-establish treatment gains. Clinical Strengths and Limitations of the Westmead Program A simple procedure Of all the treatments discussed, this is the simplest. So much so, in fact, that as soon as the parent and child learn to do the procedure, clinic visits begin to occur fortnightly. It may be useable for immediate early intervention Rhythmic stimulation is quite a simple procedure, so it may be more useable with younger children than is the case for the Lidcombe Program. Treatment credibility and expectancy There is a strong theoretical basis to the Westmead Program, not in the sense of stuttering causality, but in terms of the mechanism that might explain it. Apart from the fact that syllable-timed speech seems to be the oldest stuttering treatment method on record, the P&A Model described during Lecture Three provides a credible explanation for how it might work; syllable-timed speech removes the stress contrasts that trigger stuttering moments. A repetitive and drill-like procedure this aspect of the treatment could prove to be troublesome as it develops with further clinical trials. Even though parents rapidly learn to do the treatment with their children, it may prove to be quite wearing for them to sustain for long periods in order to obtain durable stuttering control. Summary the pre-school years are a time when stuttering is at its most tractable and when parents have optimal access to their children during daily life. Therefore early stuttering intervention is a desirable clinical option, either within-clinic or telepractice treatment. There are three treatment types for pre-school children for which there is clinical trial evidence: the Lidcombe Program, treatments based on Multifactorial Models, and the Westmead Program. The three treatments differ in clinical process and each has distinctive strengths and limitations. Practice sessions and Treatment during practice sessions used for too long into treatment.

For that 1 format, the first Phase I non-randomised clinical trial with Australian children was published in 1990. Fifty-four children were randomised, and clinical outcomes for the standard and group treatment are were consistent with outcomes from other clinical trials. However, the children in the group arm required around half the number of clinical hours than the children in the standard arm. The design is known as a parallel, open plan, non-inferiority randomized controlled trial. Results showed no reason to believe that the webcam Lidcombe Program was less efficacious in terms of stuttering severity outcomes, or cost, than the clinic presentation. In fact, the webcam arm of the trial had 17% shorter treatment consultations than the clinic arm. There was no reason to believe that parents and children in either arm of the trial had a different relationship with the treating clinicians. It could turn out that this treatment method will be suitable for the majority of families. On the other hand, that may not be so and the final place for telepractice Lidcombe Program intervention may be as part of a stepped care public health approach to early stuttering. It provides the simplest and most cost efficient method of health care that is efficacious. It is self-correcting so that clients progressively escalate to more resource intensive, and more costly, models of health care if they are shown to need it. So, if families do not respond to telepractice early stuttering intervention, they might then go to a clinic each week. Or an intervening step might be that telepractice Lidcombe Program intervention is supplemented by occasional clinic visits. Work has begun to develop a standalone Internet Lidcombe Program treatment 17 that does not require a clinician, suggesting the possibility of such treatment as the first intervention in stepped care. The stepped care intervention model has been shown efficacious with management of 18,19,20,21,22 several disorders, but there seems to have been only one description of the stepped care 23 concept applied to stuttering. The Lidcombe Program in different cultures the treatment focuses on being a positive experience for children, and, as such, praise and acknowledgment for stutter-free speech is usually a clinically essential parent verbal contingency. Four Malaysian pre-school children were studied, one of whom was treated in Mandarin and the others in English. The numbers of clinic visits to reach Stage 2 were 21, 31, and 57, which were longer than usual treatment times for the Lidcombe Program (to be overviewed shortly). The researchers reported that this seemed to have been caused by additional time required to teach the parents verbal contingencies, particularly praise for stutter-free speech. The researchers suggested approaches to the cultural issues about praise with the Lidcombe Program, such as variation of tonal and facial expression. Four of the children completed Stage 1 and based on beyond-clinic recordings were stuttering below 1. The authors reported that praising the children did not come naturally to the parents, and more time was spent training them to use verbal contingencies than is typical for Western parents.

For example blood pressure medications buy generic labetalol on-line, the theory of gravitation is often referred to as the law of 24 gravitation heart attack olivia newton john buy labetalol 100mg on line. Stuttering presents so many things that need to be explained by a theory blood pressure medication icu cheap 100mg labetalol otc, and a causal theory of stuttering needs to be evaluated in light of how well it explains them pulse pressure compliance buy labetalol 100mg otc. The following are just some of the prominent research findings about stuttering that causal theories need to take account of in order to be credible blood pressure of 14090 effective labetalol 100 mg. Why does it have such a range of behavioural manifestations involving different types of repeated movements blood pressure goals labetalol 100mg with visa, fixed postures, and superfluous behavioursfi Even more challenging for causal theory is that everyone who stutters does so in a different way, even though they obviously have the same disorder. They have different types and combinations of the seven stuttering behaviours described during Lecture One. The influence of spoken language As outlined during Lecture One, stuttering moments are not random but tend to occur more on consonants than vowels and mostly on initial sounds of words and on initial words of utterances. Those who stutter often encounter idiosyncratic difficulties with particular sounds and words. It is even more challenging for causal theory to explain that language is not even necessary for stuttering to occur; 25 stuttering can occur experimentally on non-words, where lexical processing is not necessary. Epidemiology As outlined during Lecture Two, stuttering begins during the pre-school years, but why not later in lifefi Why does it sometimes begin abruptly and sometimes gradually, and why are repeated movements often among the first signs of stutteringfi Conditions that reduce or eliminate stuttering There are diverse fluency inducing conditions as outlined during Lecture One. Stuttering nearly always vanishes when people sing or speak in rhythm, or when they speak under chorus reading or shadowing conditions. Stuttering decreases with verbal response contingent stimulation and under conditions of altered auditory feedback and masking. Stuttering and wind musical instruments Playing wind instruments has in common with speech that it involves respiratory activity combined with tongue and lip movements. There are intriguing reports, dating from the early 1950s, that some 26,27,28,29 29 who stutter appear to do so when playing a musical wind instrument. Stuttering and manual tasks Although there have been findings to the contrary, there are research findings that signs of the disorder are to be found outside the speech mechanism. Examples include delayed manual reaction times for 30,31,32 33,34,35 those who stutter and finger movement tasks. There have been recurring reports that those who stutter do not perform as well as controls with bimanual motor sequences. One research group has found this to occur with finger tapping, key pressing, handle turning, and even peddle 36,37,38,39,40,41,42,43 44,45,46 pushing. Such results have been independently replicated, and interest in the 47 topic seems to persist with a further replication. Compared to controls, those who stutter have been 48 shown to have more timing asynchrony when playing piano melodies. All this is even more intriguing than findings about playing wind instruments and speaking nonsense words, because such tasks have nothing at all to do with speech. There is evidence, however, that the effect is not present 49 with pre-school children who stutter, raising the suggestion that the effect is connected with the effect rather than the cause of stuttering. It is likely to vary with differing audience sizes and 50,51,52 types, generally with more stuttering as audiences become larger. It seems that there will be more stuttering when speaking to 52,54,55,56 people than when speaking alone. The latter study showed with a group a 60% stuttering reduction when alone compared to when an experimenter was present. Experiments that have involved repeated measures of participants in the same speaking situation have shown clinically 57,58,59 significant stuttering variability in that same situation. A study of six participants over five clinic 60 visits spanning 2 weeks showed that in two cases stuttering severity was four or five times greater on some visits than others. Statistical process control charts are a method of studying variation, and that method has been applied 61 to stuttering. The stuttering severity of 10 adults was studied during the course of their speech during a single day. Results showed that all 10 showed predictable variation around their mean severity. Stuttering and genetics Any causal theory of stuttering needs to be able to explain, as outlined during the previous lecture, that genetics is obviously involved with stuttering. Although details are not fully known at present, inheritance of stuttering obviously is complex, with a number of genes involved. Brain structure and function Also as discussed during the previous lecture, any causal theory of stuttering needs to take account of research findings connecting stuttering and problems with brain structure and function. Those findings are suggestive of a genetically determined problem with myelination of white-matter tracts. Multifactorial models of stuttering causality In short, multifactorial models state that stuttering is caused by the interaction of many factors to be found in the living environments of early childhood and within children themselves. To say it precisely, these models specify nothing as necessary or sufficient for stuttering development. The demands on children come from the living environment, and include excessive parent language expectations, constant time pressures of living, and excessive parent demands for advanced cognitive performance. Four capacities of children are proposed: speech motor control, language development, social and emotional functioning, and cognitive development. The prominence of the Demands and Capacities Model prompted an entire issue of the Journal of Fluency Disorders to be devoted to it in 2000. The first shows a situation, on the left, where demands exceed capacity, and hence were stuttering occurs. The situation on the right shows a scenario when capacities exceed demands and stuttering does not occur. Another 74 variant is known as the Dual Diathesis-Stressor Model, which includes a temperamental proclivity component. Although extensively popular theoretically and clinically, the Demands and Capacities Model has 6,75,76,77,78,79,80 been criticised many times, and those criticisms imply criticisms of multifactorial models in general. Those criticisms reiterate the point that multifactorial models are not testable and hence not falsifiable. An obvious problem for them is explaining the epidemiological fact that most stuttering appears during such a narrow age range during the pre-school years. Also from an epidemiological perspective, it is problematic that the models specify that a cause of stuttering is located in the living environments of early childhood. How could it be, then, that stuttering persists throughout life when that early childhood environment no longer existsfi For a related reason, multifactorial models do not explain stuttering variability across time and situations throughout adult life. The table presents a suggested summary of the explanatory power of multifactorial models. Such criticism is justifiable, considering that they are logically impossible to test and that their explanatory power is questionable. Rather than providing theoretical understanding of why stuttering develops during early childhood, they seem only to restate the problem; children begin to stutter because they are unable to do otherwise. Regardless, multifactorial models currently enjoy clinical popularity as a basis for techniques to control of early stuttering, and 81,82,83,84,85 they have prompted laboratory studies exploring their clinical usefulness As discussed during Lectures Six and Seven, there have been two clinical trials of such techniques. Variants of multifactorial models seem not to have sustained much interest so far this century, 73,86 although they have been described in a clinical context within two book chapters, and they still feature as topics of presentations at international conferences about stuttering. One peer-reviewed 87 70 scientific journal publication restates an existing model with accompanying explanation of how it is broadly consistent with some aspects of current knowledge about the disorder. Yet the publication seems to add nothing about the explanatory power of the model. The Interhemispheric Interference Model It appears that the first formal proposal of this model, implicating the supplementary motor area, 88 occurred in 1987. The first is that the supplementary motor area of the brain is inefficient, and the second is that the system of hemispheric activation is over-reactive. These two factors are proposed as necessary and sufficient for the development of stuttering; either factor alone is not necessary. The Interhemispheric Interference 89 Model is an extension of the now-defunct Orton-Travis Theory, but departs from it by specifying that those who stutter have normal lateralisation of speech functions. It refuted earlier findings of differences in symmetry between stuttering and control participants for that anatomical structure. It has 6 been argued that the model is difficult to refute experimentally because neither of its two brain components are operationally defined: the inefficient supplementary motor area and the over-reactive process of hemispheric activation. However, the model developers reported that it was verified with 88 an experiment where stuttering and control participants performed a finger-tapping task with a concurrent task using the other hand. The stuttering participants had more interference from the concurrent task than the controls. Another experiment, though, caused a problem for the model by showing that the same result 95 occurred with a bimanual writing task: writing with both hands concurrently. The results were consistent with a cognitive problem rather than a physical problem with concurrent left and right handed activity. The experiment was designed to determine whether the model could explain natural recovery in terms of speech motor control maturation, specifically in the supplementary motor area. Participants were those who had recovered from stuttering, those with persistent stuttering, and controls. Consistent with previous findings, recovered stuttering participants and controls performed better than stuttering participants with the bimanual tasks. However, the stuttering and recovered stuttering participants performed equally poorly on the visual tasks, suggesting that the latter group retained residual interhemispheric problems. The model certainly can explain the manual sequencing anomalies that have been found in those who stutter. Additionally, explaining the influence of spoken language and stuttering variability seems problematic. It is able to 90 explain at least some of early epidemiology with the natural recovery study. It might also explain the narrow range of stuttering onset in terms of early language development exposing the underlying hemispheric problem at that developmental stage. It can explain the fluency enhancing conditions because they could simplify speech motor activity to compensate for a problem with interhemispheric speech processing. Stuttering with wind instruments, nonsense words and bimanual tasks can be explained by the model, because it does not specify that the brain problems are speech specific. It dates back to the early years of the last century and Lee Edward Travis who proposed the 89 Orton-Travis theory of cerebral dominance, the origins of which are apparent in a 1925 report about 98 dyslexia. In 1978 Travis recounted tests of the Orton-Travis theory that were presented in a 1931 99 100 textbook, long before the arrival of scientific journals in the discipline: When I published the cerebral dominance theory of stuttering in 1931, I presented in its support three laboratory findings: (1) reductions of the patellar tendox reflex latency, (2) reductions in the amplitude of tremors from extended right forefingers, and (3) profound alterations in the alternating phasic movements (opening and closing) of both hands, all during tonic stuttering blocks (p. In a 1978 100 publication, Travis outlined how the theory was able to explain a series of research findings in the 1960s and 1970s. That historical background could prompt speculation about the future of this idea about stuttering causality. It might be interpreted as an encouraging sign that, for more than 80 years now, the Interhemispheric Interference Model has resisted definitive experimental disproof and its future is auspicious.
