Advances in technology have increasingly cast a spotlight on the possibilities for children with hearing loss, however severe, to learn to listen and use spoken language as their preferred mode of communication.   Auditory Verbal Therapy (AVT) has gained prominence as the intervention of choice for these families and their practitioners.  Auditory Verbal Therapy: For Young Children with Hearing loss and Their Families, and the Practitioners Who Guide Them provides a current, comprehensive and evidence-based text with appeal for a broad spectrum of professionals. The editors’ global experience reflects in, and influences the text, as does the work of 29 contributors, all international experts in their fields.

This is a substantive book:  seventeen chapters spanning 600 pages.  While this might initially seem daunting, the text makes for absorbing reading.  Much of the information is presented to encourage a fresh look at familiar topics. Throughout the text, the latest thinking and research is applied to AVT. In Chapter 2, hearing and listening are naturally paired with thinking and its accompanying research.  In Chapter 8, extensive and relevant information covering auditory processing, speech, language, emergent literacy and play is linked to developmental scales to provide diagnostic guidelines for practitioners.  Chapter 9 explores emergent literacy and provides compelling data that highlights the importance of early and effective access to sound for infants with hearing loss.  Very topically, it includes a balanced perspective on digital literacy.  For students and practitioners seeking practical knowledge in skill development, there are a number of ‘How to…’ chapters that have the potential to be used as ‘templates’ for acquiring skills or refining professional practice.

Unlike most texts, where the emphasis is directed at a particular group of practitioners, this inclusive text speaks to a broader audience within the field.  The material presented in chapters 4 – 7, covering audiology, hearing aids, implantable hearing technologies and assistive and access technologies, balances the next chapters, which provide greater depth for Auditory Verbal practitioners in particular. This balance between depth and breadth creates a must-have reference for the broader professional community interacting with cochlear implants.

The final chapter presents the voices of families from twelve countries as they reflect on their journeys with their children with hearing loss. Their reports, told from this powerful perspective, bear touching and convincing testimony to the global reach of AVT.

The lay-out of the book contributes to an ease of understanding that would be appreciated by parents, students and others not wholly familiar with the field.  Generous spacing, bulleting and frequently highlighted sub-sections creates a navigable reading experience and serves as a useful reference for those who prefer to use the text as a ‘dip-in’ resource.

Given its broad appeal to professionals and families, its presentation of extensive current, researched information and practical application to AVT, as well as its easy navigability, this resource may well replace existing texts to become the favoured ‘go-to’ resource for practitioners, students, families and the broader CI community seeking exploration and guidance in the field of AVT.

Speech-Language Pathologists Climbing the Steps to Mastery

Speech-Language Pathologists Climbing the Steps to Mastery
By Lydia Kopel
Co-author of IEP Goal Writing for Speech-Language Pathologists: Utilizing State Standards

Facing the mountain
As a speech-language pathologist (SLP), you are forever tackling a huge mountain called language. There are peaks at the top that you are trying to help your students/clients reach. Do you ever find yourself working on a skill with a student/client who does not seem to be making progress? That peak didn’t seem so far away, but along the way, you encounter twists and turns, making it around one corner only to face an obstacle around the next bend. Frustrating, right? On the inside you’re screaming, “Why can’t he get this? How can I approach this in a different way? What am I doing wrong?”

You’ve set your goal(s) for this individual carefully choosing the target skill(s). But, did you think about prerequisite skills? Prerequisite skills are all the skills that lead up to the targeted skill; the building blocks. Every skill has several prerequisite skills; each prerequisite skill has prerequisite skills. With language learning there is a great deal of scaffolding – one skill builds upon another skill, builds upon another skill, and so on. Let’s look at an example related to the skill of the main idea.

To be able to identify the main idea when it is not stated in a text, one has to have success with many other language skills. These include being able to answer factual questions, determine important details from unimportant details, determine how the details go together in the sequence of events, and be able to draw inferences. Of course, each one of these skills has even more prerequisite skills! And it doesn’t end there!

Each target skill also has several steps to mastery. With the same example of the main idea, we probably shouldn’t expect that a 6th grade student will learn the prerequisite skills outlined above and be able to identify the main idea and supporting details from a grade level text in one year. It is more likely that additional scaffolding and instruction will be needed at various steps. The student may first need to identify a supporting detail when given a choice of three and given the main idea in a 5th grade text. Maybe then you can move them to identifying three details that support a given main idea in a 5th grade text. With further scaffolding, this student may move toward identifying the details in a 6th grade text when the main idea is unknown. Going through these prerequisite skills and steps to mastery can increase an individual’s success and decrease therapist and client frustration—making for a much smoother climb up that language mountain.

Peaks and valleys
We all encounter those individuals who have splinter skills.   They have some of the language skills in the developmental continuum but are missing others. There may be no specific order, no rhyme or reason, to what they can and cannot do. If we can tap into the skills that haven’t fully developed, we can help increase performance on the target skills that are lacking.

Let’s look at the semantic skill of compare/contrast. Perhaps you have a client who can label pictures of nouns and verbs. He can tell you the color, size, and shape of single pictured items. He may be able to use comparatives and superlatives. However, he can’t sort items by attribute, identify things that do not belong, or state category labels. His describing skills are limited because he breaks down when more than one item is pictured together in a scene and more than two descriptors are expected.  Would it be reasonable to expect this client to state how two or more items are the same or different? It seems like there may be numerous gaps in his semantic skills that would be imperative to the skill of compare/contrast.

Reaching the peak
As an SLP, do you have students/clients who are lacking some of the necessary prerequisite skills? Taking the time to figure out what prerequisite skills are needed can lead to success with the target skill(s).   Take a step back and work on the missing skills. Sometimes we need to go backward in order to move forward.

When setting goals, consider the amount of prerequisite skills needed and how fast you anticipate the student to progress. Is your anticipated target skill too high? Maybe you need to aim for a smaller peak. Maybe the goal needs to be one of the prerequisite skills. Take it one step at a time and you’ll soon find the individual standing at the peak.

Prerequisite skills, goal writing, and much more are discussed and outlined in the book IEP Goal Writing for Speech-Language Pathologists:  Utilizing State Standards. Check it out!

Auditory-Verbal Therapy provides a thorough, 21st century resource for professionals, families, and students. Each chapter is organized in a way that technical information is accompanied by suggestions for practical application, making it a likely “go-to” reference that will be consulted frequently.

The history of Auditory-Verbal therapy (AVT) described in the first chapter is comprehensive and much needed in order to ensure that the story of the approach is not lost to current and future generations of professionals and families. The book is clear about the principles of AVT, what it is and is not, all while demonstrating how AV therapy has evolved to apply evidence-based practices that meet the needs of today’s diverse families and children.

A highlight of the book is a systematic review of literature concerning AVT that utilizes the most current techniques and standards for scientific rigor to describe the state of evidence supporting the approach. The chapters that address audiological procedures and hearing technology are current and provide a basis for deeper reading of the topics discussed. The book addresses each of the knowledge domains that Auditory-Verbal therapists apply in practice, including comprehensive developmental milestones, emergent literacy, inclusion and specific strategies for parent coaching.

An important section of this book provides a rationale and framework for planning and implementing AVT sessions, followed by a series of case studies and lesson plans written by experienced AV therapists that apply this framework. The children and families in these case studies and lessons represent a range of ages, diagnoses, additional disabilities, and cultural/economic situations. The lesson plans at first glance may not seem like conventional lesson plans. They illustrate how important teaching within the conversational context is in AVT, beginning with initial greetings and entering the therapy room or home. Following the child’s lead and exploiting teachable moments are highlighted.

Finally, families from across the global community tell their own stories, demonstrating the universality of the approach. The families not only hail from many different countries, but they are each unique in their cultural and economic situations, types of hearing loss and the ages at which their children entered AVT. Many of the children in these families have challenges in addition to hearing loss.

This book is a must-have for anyone who works with children with hearing loss and their families. The information has value for professionals and families across the communication options that families might choose. This book is essential for professionals working to attain Listening and Spoken Language Specialist certification. It will guide their learning during their certification period and serve as a foundational source for examination preparation.

Nasal Emission Terminology Should be Evidence Based and Consistent with Physiology and Perceptual-Acoustic Characteristics

Nasal Emission Terminology Should be Evidence Based and Consistent with Physiology and Perceptual-Acoustic Characteristics (1)David J. Zajac, PhD, CCC-SLP, ASHA Fellow

Coauthor of Evaluation and Management of Cleft Lip and Palate: A Developmental Perspective

The term “cleft palate speech” has often been used to refer to hypernasality, nasal air emission, reduced oral air pressure, and compensatory articulations of speakers who exhibit velopharyngeal inadequacy (VPI). Hypernasality is defined as excessive resonance of the nasal cavity during production of vowels and voiced consonants. Nasal air emission refers to the audible escape of air during the production of high-pressure oral consonants, especially voiceless consonants. Reduced oral air pressure is the flip side of nasal air emission. When air escapes through the nose, some oral air pressure is lost. Thus, oral pressure consonantsespecially voiceless ones—may be produced with reduced oral air pressure and perceived as weak or reduced in intensity. Compensatory articulations are maladaptive gestures that are produced at the glottis or in the pharynx as a way to circumvent a faulty velopharyngeal valve. The use of glottal stops to replace oral stops is a classic example of a compensatory articulation. Hypernasality, nasal air emission, and reduced oral air pressure are passive (or obligatory) symptoms of VPI. This means that the symptoms occur as a direct consequence of incomplete velopharyngeal closure. Compensatory articulations, however, are active (or learned) behaviors and may not occur in every individual.

Although obligatory nasal air emission is a core characteristic of VPI, many confusing, overlapping, and inaccurate terms have been used to describe its perceptual manifestation. The literature is replete with terms such as audible nasal air emission, nasal turbulence, nasal rustle, and passive nasal frication. Because the velopharynx and nasal passage are complex anatomical structures— which may be significantly altered due to both congenital defects and surgical interventions associated with cleft lip and palate—the variety of terms used to describe nasal air emission should not be too surprising. Numerous other terms have been used to describe nasal air emission that is part of active (or learned) nasal fricatives and will not be discussed here. The reader is referred to Zajac (2015) for a discussion of active nasal fricatives as an articulatory error. Rather, this article will focus on terminology used to describe passive or obligatory nasal air escape.

A Brief History of Current Terminology

McWilliams, Morris, and Shelton in the first and second editions of Cleft Palate Speech (1984, 1990) described nasal air emission as occurring along a continuum. First, it could be visible but inaudible, detectable only by holding a mirror under the nostrils of a speaker to see fogging as a result of the air emission. In such a case, the nasal airflow is laminar, moving in relatively smooth fashion, and does not become turbulent, or noise producing. Clinically, visible nasal air emission typically occurs in speakers who have adequate but not complete velopharyngeal closure and normal resonance. Although visible nasal air emission should be noted when it occurs in a speaker, there are no treatment implications. Continue reading

Auditory-Verbal Therapy- Hearing, Listening, Talking, Thinking

Warren_Estabrooks

 

 

By Warren Estabrooks, M.Ed., Dip. Ed. Deaf, LSLS Cert. AVT, co-author of Auditory-Verbal Therapy: For Young Children with Hearing Loss and Their Families, and the Practitioners Who Guide Them

 

 

Globally, there is a great shift towards listening and spoken language for children who are deaf and hard of hearing.

Amazing auditory options, state-of-the-art hearing aids, and a variety of implantable hearing devices and the pursuit of excellent (re)habilitation by highly qualified practitioners working in partnerships with families, will hopefully become the standard of international health care and educational intervention for children with hearing loss around the world.

It is the work of therapists, teachers, audiologists, surgeons, social workers, and allied practitioners in health care and education to guide, navigate, and coach parents on their search for the treasure chest of spoken communication—to help them help their children discover the valued jewels of hearing, listening, and spoken conversation.  Practitioners everywhere form alliances of hope and trust with parents, and together we polish these precious gems until they sparkle and dance with life.

Why would one ever consider compromising when so much is possible?

We hope that one day we will look back and see an abundance of evidence-based outcomes, all barriers to equitable service gone, and a global focus on literacy with a deep understanding of powerful auditory access to the brain provided by state-of-the-art hearing technologies.

Renaissance man and mentor of many of today’s auditory-verbal practitioners, Dr. Daniel Ling, wrote that “auditory-verbal therapy… developed as a result of the natural outcomes of advances in knowledge, skills and technology.  As such advances occurred, new treatment strategies were devised to maximize their applications”.

Auditory-Verbal Therapy is now widely accepted because more children are acquiring, or have already acquired, the abilities to use spoken language, to interact more freely with other members of society, to obtain higher levels of academic education, and to have a more extensive range of careers, a greater security of employment and fewer limitations on the personal and social aspects of their lives” (Estabrooks, 2006).

Healing Voices

Healing Voices (1)By Leda Scearce, MM, MS, CCC-SLP author of Manual of Singing Voice Rehabilitation: A Practical Approach to Vocal Health and Wellness

Singing is a part of virtually every culture and is fundamental to our human experience. In the United States, singing is enormously popular, as evidenced by the vast number of people engaged in all kinds of singing activities. Over 30 million Americans participate in choral singing alone (Chorus America, 2009). Shows such as The Voice, America’s Got Talent, and American Idol illustrate how passionate we are about singing. From the amateur recreational singer to the elite celebrity, we sing as soloists and in ensembles, with instruments and a cappella, in classical and contemporary styles, on stage, in concert, and in the shower.

Every person’s voice is unique and identifiable, and our voices can be a big part of our identity and how we see ourselves in the world. This is especially true for singers, for whom the voice is not only intricately tied to self-image and self-esteem but also may be a source of income and livelihood, creative expression, spiritual engagement, and quality of life. For a singer, a voice injury represents a crisis. Because of the specialized needs of singers, it takes a team—including a laryngologist, speech-language pathologist, and singing voice rehabilitation specialist—to get a singer back on track following an injury or voice disorder. Singing voice rehabilitation is a hybrid profession, requiring in-depth clinical and scientific knowledge married with excellence in teaching singing.

Voice problems are rarely isolated in etiology—usually multiple factors converge to create an injury. These factors may include poor vocal hygiene, inadequate vocal technique, an imbalance in vocal load and medical problems (allergies and reflux are common in singers, but thyroid, pulmonary, neurologic, and rheumatologic conditions are among the illnesses that may affect the voice). The singing voice rehabilitation process must encompass all elements that may be contributing to the problem: medical factors, vocal hygiene, vocal coordination and conditioning, vocal pacing, and emotional factors.

The Changing Indications for Cochlear Implantation

Theodore R. McRackan, MD Otology, Neurotology, and Skull Base Surgery

By Ted McRackan, MD, co-editor of Otology, Neurotology, and Skull Base Surgery: Clinical Reference Guide

Cochlear implantation is the gold standard for treatment of severe to profound sensorineural hearing loss. Cochlear implants (CIs) were approved by the Food and Drug Administration (FDA) in 1985 and have been suggested to be the most successful neural prosthesis created to date. Over 300,000 cochlear implants have been performed worldwide, with over 50,000 performed in the past year alone. Cochlear implantation involves a surgical procedure whereby an electrode array is placed in the cochlea of the inner ear, which is organized in a tonotopic fashion with decreasing characteristic frequency along its length. Modern CIs contain between 12 and 22 electrodes, which are spaced with the intention of each electrode stimulating a unique area of the spiral ganglia of the auditory nerve. Cochlear implants work by having an external microphone and an external processor convert an acoustic signal to an electrical signal. It is then sent to a speech processor, which is designed to enhance the signal and reduce noise before sending the information to the spiral ganglion through the CI electrode array.

Cochlear implantation is currently at an exciting time point due to the combination of improving technology and proven outcomes that has led to rapid expansion of its indications. The FDA approved the first single-channel CI electrode for adults in 1984, followed by the multichannel electrode in 1987. Cochlear implants were then approved in 1990 for children older than 2 years, in 1998 for children over 18 months, and ultimately in 2000 for children older than 12 months. There has been a recent push to implant children younger than 12 months due to evidence that children implanted at this age are more likely to catch up to normal-hearing peers at an earlier time point. Three major obstacles have hampered this movement. First, obtaining accurate hearing diagnostic testing in a timely manner can often be difficult in those less than 12 months. Second, there is a slight increased risk of surgical complications due to the low blood volume in this age group. Third, it can be extremely difficult to perform cochlear implant programming in this age group. Nonetheless, the clear benefits of early implantation likely outweigh these risks. Pediatricians, audiologists, and otolaryngologists are encouraged to identify infants with hearing loss as soon as possible for hearing rehabilitation. The earlier this is performed, the earlier children with profound hearing loss can be identified, and the earlier they can be implanted, leading to better CI outcomes.

Use of cochlear implantation in patients with residual hearing has been another area of rapid expansion. It was initially thought that all hearing would be lost with cochlear implantation and that if hearing was preserved, patients would not be able to process electrical and acoustic hearing. However, through the trials of the Cochlear Hybrid electrode and the MED-EL EAS electrode, it appears that both are possible. Through these and other trials, most patients had preserved residual hearing after cochlear implantation. Additionally, these patients showed improved hearing outcomes compared to patients without residual hearing. At the present time, it is not clear whether this preserved hearing is sustainable over time. This is an active area of investigation and will continue to be studied for years. Nevertheless, this technology has greatly expanded the indications for cochlear implantation beyond traditional candidacy.

As discussed above, it was previously thought that individuals would not be able to process combined electrical and acoustic hearing. However, cochlear implantation in patients with residual hearing proved this incorrect. This has led to the more widespread use of CIs in individuals with single-sided deafness. Current standard treatment for single-sided deafness includes devices that essentially ignore the deafened ear. However, with cochlear implantation, hearing can be restored to that ear. This was initially performed in patients with severe tinnitus in the deafened ear but is now being more commonly performed in the absence of tinnitus. Further work is certainly needed to develop a more comprehensive understanding of cochlear implantation in this population, but preliminary data show decreased head shadow effect and improvement in binaural summation, spatial release from masking, and potentially sound localization.

Beyond cochlear implantation, the use of auditory brainstem implants (ABIs) in children is another area of expansion. Although this has been performed in Europe for years, it is only more recently being performed in the non-neurofibromatosis type II population in the United States. Several centers have active clinical trials to perform ABIs in children unlikely to benefit from cochlear implantation due to either absent cochlear nerves or cochlear malformations. This is an unfortunate population as they have limited hearing rehabilitation options. Auditory brainstem implants provide an opportunity for hearing in this population, and the neurotology community is excited to hear the results of these trials.

We have come a long way since Bill House developed the first single-channel CI. As outcomes and technology continue to improve, the indications for cochlear implantation will grow. The audiology and otology communities are eager to see what the future holds for cochlear implantation.
