Augmentative/Alternative Communication (AAC) for Aphasia

Communicating When, Where and What You Want

The high and low tech of augmentative and alternative communication for aphasia


Benefits and Challenges

A benefit of high-tech AAC is capacity. A physical notebook can only hold so many pictures, but a smartphone or tablet can hold thousands.

A hand holding a message: A physical notebook can only hold so many pictures, but a smartphone or tablet can hold thousands.

“There are several mobile applications that combine the use of photographs, writing, drawing and text to allow the individual with aphasia to use those to support their communication,” McKelvey said. “It can be programmed with a greeting for your daily coffee order. Sometimes, we use what we call a floor holder that introduces the individual using AAC and says, ‘I’m using this communication device to help because it’s difficult for me to get my words out, but I can understand what you’re saying.’ It really depends on the individual needs of the person.”
Some patients prefer the high-tech, and both experts surmised that this reflects the person’s comfort with technology before the stroke. “Our folks who are in their 80s, 90s and sometimes 70s just prefer to use low-tech strategies,” McKelvey said. “But this next generation may be different. They are used to using technology all the time and may want to use … this type of technology for communication as they’re so familiar with it.”

A little over a decade ago, someone carrying around a device all the time might have seemed odd. “With the proliferation of tablets, there is less stigma involved in somebody using or carrying around a tablet that they use for various purposes because lots of people do it,” Gutmann said. “Even dedicated devices these days maybe have sort of a tablet-looking- type device or a laptop type of device, so they may not be as different looking as they may have been in the past.”
High-tech allows for more complexity in communication. “In most high-tech systems, you can prepare and save messages and have them ready to go,” Gutmann said. “You could also communicate across space with something that has a voice output, so you could talk on the phone, whereas for the most part, low-tech options are very limited in that respect.”
Complexity can be a challenge with high-tech AAC — ease of navigation, ease of organization and customization are important. If survivors can’t make it their own, it will never be part of them. “It has to be organized and personalized for the individual who has aphasia. It really has to make sense for the user,” McKelvey said. “It can be a challenge to figure out how it is going to be most facilitative. A lot of trials and feedback about ease of use are necessary. When we design something for a patient, they have to take it out and use it. Then we come back together and talk about what worked and what didn’t. How can we make this better?”
Gutmann emphasized that programming is time intensive. “It can be fabulously successful, but it can also fall flat on its face if you don’t have buy-in from the person with aphasia and their most important conversation partners,” she said. “Also, there are so many considerations for systems. You have to consider if the person can navigate it. Can they use a smartphone? People who were tech users before they had aphasia may be more inclined to embrace this as part of their AAC. People who weren’t users of tech before they had aphasia may find themselves less inclined to embrace this as part of their intervention.”
High-tech AAC requires a battery or an electrical outlet. And, as amazing as it is, technology always has the potential not to work. “I never have an individual communicate using just one method because I don’t communicate using just one method, so I don’t expect my patients to,” McKelvey said. “There has to be a low-tech way for them to communicate when their high technology isn’t available to them for whatever reason — it doesn’t get plugged in, it doesn’t work that day, they left it in the car, whatever.”
If something does go wrong with a mobile tablet, what then? “Who’s going to be this person’s tech support?” Gutmann asked. “Is it going to be their spouse, their child, their best friend, their grandchild? A dedicated speech-generating device is going to come with tech support from the manufacturer. But when you buy a commercially available tablet and an app, who’s responsible for that? If something goes wrong, do you take it back to the place where you got the tablet? Maybe it’s not a tablet issue; maybe it’s a problem in the app. Maybe it needs updating. Maybe there’s a problem with the device. It’s harder to disentangle those things.”
Neither low-tech nor high-tech AAC is better than the other. But it’s not hard to imagine that using tech that actually speaks for you can make a different impression. “You might be perceived as smarter, more able, more capable,” Gutmann said. But not all people will relate to an artificial voice coming from a device. And there are situations that may require low-tech AAC. “What happens when the power goes out, or you need to communicate in the shower or bath? If you need help with those type of tasks, you can’t be taking a tablet or a dedicated device into the bath or the shower.”

Thought bubble with message: Sometimes the choice between low and high tech boils down to simplicity.

Sometimes it boils down to simplicity. “Honestly, a lot of my patients just prefer the low-tech because they can write or draw or use the word list, and it’s just easier for them to communicate using those methods,” McKelvey said. “It really depends on how efficiently they can locate what they want to say when they need to say it. Personalizing the organization and vocabulary within the AAC system can lead to successful communication.”

Costs

“Cost can be a barrier for some individuals — if you’re looking at a particularly sophisticated speech-generating device, up to $7,000,” said McKelvey. “Speech-generating devices are considered essential durable medical equipment by Medicare and Medicaid, but there has to be an evaluation from a speech therapist.” Getting Medicare or Medicaid to cover the cost requires paperwork and the process for approval can take some time. McKelvey tells us that there are programs and organizations that may offer equipment on loan. This gives individuals with aphasia a chance to try out the technology first. “If we’re talking about an app on a phone, those can be anywhere from $5 to $250 plus the cost of the device,” she said.

This week starts a series of a article I found at strokeconnection.org. I have broken down the article into three sections because it is lenghty. This week it will describe what AAC is. Next week will cover the Benefits and Challenges of AAC, followed by Selecting a Device the third week.

Augmentative/Alternative Communication (AAC) for Aphasia

Communicating When, Where and What You Want

The high and low tech of augmentative and alternative communication for aphasia










After stroke, community is important for recovery, and communication is key. “I have learned from my patients that the most important thing for them is communication,” said Miechelle McKelvey, Ph.D., CCC/SLP and professor and department chair in the communication disorders department at the University of Nebraska-Kearney. “I’ve had so many spouses of stroke survivors tell me: ‘I used to think the worst thing would be if he or she couldn’t walk. But I never really thought about them not being able to communicate.’ It’s how we connect with our loved ones and our community, even our pets. It’s how we connect with the world.”
Speech language pathologists (SLPs) are all for anything that supports survivors’ ability to connect with their world and those in it. “My goal is that a person should be able to communicate in any environment they step into, about any topic they choose, and with any communication partner,” McKelvey said.
Augmentative and alternative communication (AAC) methods help make that happen. According to the American Speech Language and Hearing Association:
AAC includes all of the ways we share our ideas and feelings without talking. We all use forms of AAC every day. You use AAC when you use facial expressions or gestures instead of talking. You use AAC when you write a note and pass it to a friend or co-worker. We may not realize how often we communicate without talking.

People with severe speech or language problems may need AAC to help them communicate. Some may use it all of the time. Others may say some words but use AAC for longer sentences or with people they don’t know well. AAC can help in school, at work and when talking with friends and family.

Types of AAC

AAC methods generally fall into two categories — high tech and low tech.

Notepad stating: Low-tech AAC can be as simple as a notepad.
Low-tech AAC can be as simple as a notepad.
Tablet stating: Hightech AAC encompasses electronic and computerized devices.
Hightech AAC encompasses electronic and computerized devices.

Low-tech AAC can be as simple as a notepad. One of McKelvey’s colleagues developed a small pocket calendar that, instead of dates, has word lists, sentences, phrases, topics or even pictures that a person could need to communicate. “Other types of low-tech or no-tech communication would be as simple as gestures or facial expressions,” McKelvey said. “Anything that a person would use to either support what they are communicating or that a communication partner would use to support someone with aphasia’s ability to understand what’s being communicated to them.”
“Low-tech AAC can include anything from actual pictures or photographs to a communication board,” said Michelle Gutmann, Ph.D., CCC-SLP and clinical professor in Speech, Language, & Hearing Sciences at Purdue University. “You can either develop them and customize them, or there are some prefabricated ones on the market, from an emoticon [images that indicate emotions] rating scale, to something called a boogie board that is like a magic slate that can be written on but easily erased. Low-tech pretty much encompasses anything that is non-electronic.”
High-tech AAC encompasses electronic and computerized devices. “I think we have more options now because of two things that happened in terms of the research and the technology,” Gutmann said. “Starting in 2006, researchers started talking about ‘Visual Scene Displays.’ Visual Scene Displays are highly contextualized, personally meaningful and relevant pictures on a communication device that are used to help people with aphasia communicate. Then, there was the proliferation of mobile tablets that readily support the use of pictures and the many apps that support communication.”
Different mobile apps support communication in different ways. “Some applications have sentences and phrases that speak when the person presses a button,” McKelvey said. Some apps are as simple as a whiteboard surface that can be drawn or written on with a finger or stylus or an onscreen or peripheral keyboard can be helpful.
In addition to mobile apps, high-tech AAC also includes dedicated speech-generating devices. The sole purpose of these devices is to support communication, whereas a tablet supporting AAC apps also runs apps for other purposes.
Tobii Dynavox is an example of such a device. “A dedicated speech device would have presets and access to vocabulary,” McKelvey said. “Then it has to be personalized for the individual’s needs. Some apps can be customized but the features of the apps need to meet the needs of the user. The individuals with aphasia must be able to navigate through the app and locate what they want to say efficiently during the conversation. This can be a challenge for individuals with aphasia. It is important to have an AAC evaluation with an SLP to ensure this match between the needs and abilities of the person with aphasia and the features of the AAC system be it low-tech or high-tech.”
Both experts were clear that dedicated speech-generating devices are not necessarily better or worse than low-tech communication displays, notebooks and photographs. All can be useful for people with aphasia. “And every high-tech device needs a low-tech backup, something to use when the high-tech can’t be used,” Gutmann said. “Some people prefer low-tech because it requires whomever they’re talking with to be face-to-face with them, engaged with them right there and really involved in the communication. On the other hand, a high-tech system could allow somebody to prepare a message in advance. For example, going to a family reunion prepared to ask people how they’re doing and updating them about themselves.”

Next week will cover the Benefits and Challenges of AAC.
