A 12-month follow-up of preschool children investigating the natural history of speech and language delay.

AIM: The aim of this paper is to examine the natural history of early speech and language delay in preschool children over a 12-month period. METHODS: The study reports data on 69 children under the age of 3.5 years who were referred for speech and language therapy because of early speech and language delay. The children were monitored over a 12-month period but received no direct intervention during that time. Assessment of their comprehension, expressive language and their phonology took place at baseline and again at 6 and 12 months after baseline. RESULTS: The results show a general picture of improvement, although there was considerable individual variation. By the end of the 12 months, two-thirds of the children were still eligible on the study intake criteria. Therapist's rating of a child's functional communication at the outset was a significant predictor of the child's outcome at the end of the 12-month period. DISCUSSION: The paper discusses the appropriateness of a 'monitoring' approach to the management of early language delay and highlights the need to consider the social issues and views of parents as well as the severity of a child's difficulties.

Day in, day out: the everyday therapy of community clinics.

This paper describes the timing and nature of therapy provided within a recent randomised controlled trial (RCT) of preschool speech and language therapy services. There is literature that describes and evaluates speech and language therapy but there is little indication of how this is translated into everyday practice. The study collected data from 21 speech and language therapists (SLTs) in 16 community clinics. The areas targeted, goals, approaches used, the frequency and timing of contact for the 68 children who received treatment were documented. The data show that several aspects of therapy were frequently targeted simultaneously, that approaches were combined and that the frequency of therapy did not vary with severity. The discussion will consider the gap between published programmes and everyday practice and the implications for effectiveness.

Who's afraid of the randomised controlled trial? Parents' views of an SLT research study.

Evidence-based health care is now a reality within the national health service (NHS) and the randomised controlled trial (RCT) is the linchpin of this movement. In modern health care, there has also been a shift towards understanding client perspectives. With regard to clients' participation in research, much consideration has been given to ethical issues and barriers to participation. However, less attention has been paid to the participants' views of clinical trials and understanding how they construe the research. This paper reports a study of the attitudes of parents whose children took part in an RCT. Data were collected from the parents of 20 children, using qualitative in-depth interviews. Parents talked about the meaning of their participation, their motivation for taking part and their understanding of the nature of the trial. The implications of the findings for future research will be considered.

Randomised controlled trial of community based speech and language therapy in preschool children.

OBJECTIVE: To compare routine speech and language therapy in preschool children with delayed speech and language against 12 months of "watchful waiting." DESIGN: Pragmatic randomised controlled trial. SETTING: 16 community clinics in Bristol. PARTICIPANTS: 159 preschool children with appreciable speech or language difficulties who fulfilled criteria for admission to speech and language therapy. MAIN OUTCOME MEASURES: Four quantitative measures of speech and language, assessed at 6 and 12 months; a binary variable indicating improvement, by 12 months, on the trial entry criterion. RESULTS: Improvement in auditory comprehension was significant in favour of therapy (adjusted difference in means 4.1, 95% confidence interval 0.5 to 7.6; P=0.025). No significant differences were observed for expressive language (1.4, -2.1 to 4.8; P=0.44); phonology error rate (-4.4, -12.0 to 3.3; P=0.26); language development (0.1, -0.4 to 0.6; P=0.73); or improvement on entry criterion (odds ratio 1.3, 0.67 to 2.4; P=0.46). At the end of the trial, 70% of all children still had substantial speech and language deficits. CONCLUSIONS: This study provides little evidence for the effectiveness of speech and language therapy compared with watchful waiting over 12 months. Providers of speech and language therapy should reconsider the appropriateness, timing, nature, and intensity of such therapy in preschool children. Continued research into more specific provision to subgroups of children is also needed to identify better treatment methods. The lack of resolution of difficulties for most of the children suggests that further research is needed to identify effective ways of helping this population of children.

Issues to consider in the evaluation of speech and language therapy for preschool children.

This paper reviews some of the methodological issues involved in the design of a randomized controlled trial currently underway in Bristol. The trial compares the progress of preschool children randomly allocated to a 'watching-waiting' control group with the experimental group who have immediate access to therapy. This paper reviews a number of relevant studies, which have either followed up preschool children with early language delays or have investigated the effects of therapy with this age group. The basic design of the trial is outlined along with a discussion of the sample, the measurements used and the therapy given.

Parents' beliefs and ideas about children's early speech and language difficulties.

This paper reports a qualitative investigation of the ideas and beliefs of parents about their pre-school children's speech and language difficulties. It forms part of a broader study of parental opinions about speech and language difficulties and the speech and language therapy (SLT) intervention they receive. Factors contributing to the development of professional interest in parental views will be reviewed, followed by an outline of the beliefs and ideas expressed by the parents in in-depth interviews. The paper will also discuss parents' views in their wider context and consider implications for SLT practice.

The significance of afferent vagal information in the control of breathing in guinea pigs.

The stimulation of the central vagus nerve in guinea pigs was applied to study the role of vagal afferent information in the control of breathing. The survival time after bilateral vagotomy was measured in unanesthetized animals, under Hexobarbital anesthesia, and in anesthetized subjects when the central stump of the vagus nerve was stimulated. There were no differences in survival time between the first and the second groups, but in animals with vagal stimulation, the survival time was prolonged. The respiratory and circulatory disturbances were abolished by stimulation.

Reflex control of discharge in motor fibres to the larynx.

1. Action potentials have been recorded from single laryngeal motor fibres, with expiratory or inspiratory phases, in cats anaesthetized with pentobarbitone and breathing through a tracheal cannula.2. Pneumothorax increased the discharge of both inspiratory and expiratory units, the inspiratory response being greatly reduced by bilateral vagotomy below the origin of the recurrent laryngeal nerves.3. Addition of a ;viscous' resistance to breathing, or asphyxial rebreathing through an added dead space, increased the activity of inspiratory units and decreased that of expiratory units.4. Induction of pulmonary oedema decreased the discharge of inspiratory units and increased that of expiratory units. After vagotomy the response of inspiratory units was reversed.5. Intravenous injections of potassium cyanide increased the activity of both types of unit.6. Chemical irritation of the laryngeal mucosa decreased the discharge of inspiratory units and increased that of expiratory units, whether the vagi were intact or cut.7. It is concluded that expiratory unit discharge can be correlated with expiratory laryngeal resistance, but that inspiratory unit discharge does not correlate so well with inspiratory laryngeal resistance.8. The relationship between laryngeal motor-fibre activity and the contractions of the inspiratory and expiratory muscles of breathing is discussed.

Relative roles of irritant, type-J and pulmonary stretch receptors in lung reflexes.

Bilateral anodal block of both cervical vagus nerves of anaesthetized rabbits has been used to assess the relative role of afferent pathways with myelinated fibres (primarily from lung irritant receptors) and with nonmyelinated fibres (from J-receptors) in respiratory responses to some lung conditions. With inhalation of histamine aerosol the increase in breathing frequency is due to myelinated afferent fibres from irritant receptors. The similar response with inhalation of halothane is due to non-myelinated fibres from J-receptors. The reflex breathing response in lung oedema involves both pathways, but in the experimental conditions the myelinated pathway plays the larger part. The interaction of these two mechanisms, and the possible role of pulmonary stretch receptors, is discussed.

The cyanide gasp and spontaneous deep breaths.

Stimulation of the carotid body chemoreceptors with cyanide in anaesthetized rabbits usually causes a deep breath or gasp, but only if the vagus nerves are intact. This gasp has several similarities with spontaneous deep breaths in eupnoea. In paralysed rabbits, artificially ventilated, chemoreceptor stimulation induces an augmented discharge in the phrenic nerve equivalent to a gasp. In spontaneously breathing rabbits spontaneous deep breaths are more frequent with hypoxia than with normoxia. The results are interpreted in relation to (i) positive feedback from the lungs and (ii) summation of chemoreceptor and tonic vagal drive causing augmented deep breaths.

The respiratory action of phenyl diguanide in vagotomized rabbits.

In anaesthetized rabbits phenyl diguanide not only stimulates breathing (rapid shallow breathing) by a vagal reflex from lung J-receptors, but also causes a similar response in bilateral vagotomized animals. Injection of the drug into different parts of the circulation indicates that the main non-vagal response of breathing arises from areas supplied by the vertebral arteries, presumably in the brain.

Investigating parental views of involvement in pre-school speech and language therapy.

Today, speech and language therapists working with the pre-school population routinely involve parents in their children's treatment programmes. Also, there is increasing recognition of the importance of considering client and carer views in evaluating services. Thus, in both clinical and research terms, the role of parents is key. This paper reports an aspect of a study that investigated parents' views and perceptions of their pre-school children's speech and language difficulties and the speech and language therapy (SLT) they received. The methodology of the study was qualitative and data were collected from the parents of 16 pre-school children, using in-depth interviews. The parents' perceptions could be characterized as a process with three phases. On the whole, parents viewed their involvement in SLT positively but crucially, the interviews highlighted discrepancies between therapists' and parents' perceptions of the therapy process. The study demonstrates that when parents' views are considered, a fuller understanding of the effectiveness and acceptability of treatment can emerge.

Developing a scale to measure parental attitudes towards preschool speech and language therapy services.

In the past decade, there has been growing recognition of the need to involve clients in decisions about the healthcare they receive and in the evaluation of services offered. In health services research, survey and scaling methods have become important tools for research into 'consumer views' and the perspectives of people receiving healthcare. In spite of the increase in recent years in the participation of parents in their children's Speech and Language Therapy (SLT), there has been little attempt to investigate parents' perceptions and opinions of the services they receive. Moreover, there has been no previous attempt to derive a scale to measure these attitudes. The paper reports a study that explored the attitudes to therapy of 81 parents whose preschool children were receiving SLT intervention. Factor analysis of 12 items on a questionnaire revealed three issues salient in parental attitudes to therapy: practical help, emotional support and the perceived effectiveness of the service. The validity of these factors was supported by other findings from the questionnaire. The properties of the resulting scales are discussed and the ways in which they might be further refined and developed for use in SLT are suggested.
