What’s New? VIVIVOCA

It’s always exciting when we see new ideas take shape in AAC tools. Take a look at the research on VIVIVOCA: voice-input, voice-output communication aid. This holds much promise for clients who have poor speech intelligibility but good consistency in their error patterns, such as people with dysarthria secondary to cerebral palsy. Here’s the article. Thanks to the indefatigable Ian Bean for alerting us to this article.     Hawley, M.S., Cunningham, S.P., Green, P.D., Enderby, P., Palmer, R., Sehgal, S., & O’Neill, P. (2013). A voice-input voice-output communication aid for people with severe speech impairment. IEEE Transactions on Neural Systems and Rehabilitation Engineering, 21, 1, 23-31.

5 References That Support the Use of AAC for People with ASD

5 References That Support the Use of AAC for People with ASD

We occasionally get asked to provide empirical supports for some of the AAC tools and strategies used in our clinical work and teaching. Here are five references that we wanted to pass along. Ganz, J.B., Earles-Vollrath, T.L., Heath, A.K., Parker, R.I., Rispoli, M.J., & Duran, J.B. (2012). A meta-analysis of single case research studies on aided augmentative and alternative communication systems with individuals with autism spectrum disorders. Journal of Autism and Developmental Disorders, 42,1, 60-74. Systematic review of 24 single subject experimental design (SSED) studies investigated the impact of AAC interventions and concluded that aided AAC interventions had positive effects on communication and behavior skills. Although all picture-based AAC systems were effective, learners did best with SGDs or PECs. Checkley, R., Reidy, L., Chantler, S. Hodge, N., & Holmes, K. (2012). “Black white zebra orange orange”: How children with autism make use of computer-based voice output communication aids in their language... [Read More...]

PrAACtical Conversations: Nonspeech Oral Motor Exercises

PrAACtical Conversations: Nonspeech Oral Motor Exercises

There are some good reasons to use nonspeech oral motor exercises, like blowing, puckering, tongue lateralization, and stretching. For a period of time, I used resistance exercises extensively with one client to improve the resting posture of his articulators and help him keep his mouth closed. Good for hygiene and to reduce his exposure to germs. Using these strategies, lots of children have gained strength and control that allowed them to better bite, chew, and swallow their food. Oral motor exercises can result in some meaningful gains. According to the research, however, improved speech articulation is not among them. There have been a number of studies on this approach, including some strong systematic reviews by McCauley and others.  This summary by Dr. Greg Lof (Chair of the Department of Communication Sciences and Disorders at Massachusetts General Hospital Institute of Health Professions) is a few years old but is worth another...

PrAACtical Resources: Evidence-Based Practice Maps

PrAACtical Resources: Evidence-Based Practice Maps

– –ASHA’s Center on Evidence-Based Practice (EBP) in Communication Disordersis beginning to have some relevant information for the AAC community. While many SLPs equate EBP with research and journal articles, this is only one component. ASHA’s EPB group is working with content area specialists to develop navigable evidence ‘maps’ to highlight information in each of the three pillars of EBP: Clinical Expertise/Expert Opinion, Research, and Client/Family Perspectives. – Professionals working with children and adults who have developmental disabilities may be interested in this Evidence Map on AAC and Cerebral Palsy. Additional evidence maps that have an AAC-related component been developed for dementia, TBI in adults, and autism.

Gestures as Part of a Multimodal Communication System

Gestures as Part of a Multimodal Communication System

Gesture Recognition in Aphasia Therapy (GeST) is a project that emphasizes the use of gestures to help individuals with aphasia communicate effectively. GeST is a computer-based program to teach simple gestures and provide home practice opportunities. Project leaders used a participatory design to gain the input from 5 people with aphasia in developing the program. They are currently evaluating its effectiveness in a pilot study. We are big fans of multimodal communication and love the prAACtical applications of this program. You can check it out for yourself at this video.

5 References to Support the Use of AAC

5 References to Support the Use of AAC

When I took my daughter to a specialist awhile back, she recommended a treatment that was a bit extreme. Her verbal explanation for the expensive and involved treatment made sense, but I still wasn’t convinced and asked it there was something we could read that explained the scientific underpinnings of the approach. She disappeared for a moment and came back with a task force report on the treatment that reviewed literature on this approach. Reading through it and seeing the studies, critiques, and responses helped us make an informed decision. – Chances are, many of you have had similar experiences. Trust in our healthcare professionals is critical, but when it comes  to big decisions, we want to know the science that stands behind the options. – Making the decision to use AAC is a huge one for all of us, but families are especially burdened with its weightiness. Not only... [Read More...]
