News — Though many people suffering from neurological conditions such as cerebral palsy and Lou Gehrig鈥檚 disease have lost their ability to speak, they can communicate using augmentative and alternative communications (AAC) devices such as keyboards, head sticks, and other hands-free options. Nonverbal people, however, are also susceptible to feeding and swallowing problems (dysphagia). In late 2006 Ithaca College faculty member and speech pathologist Mary Pitti and her colleague Liz Begley (an AAC specialist now on staff at College Station Medical Center in Texas) made an eye-opening discovery: AAC devices offering icons and software applications for dysphagia sufferers were nearly nonexistent.
鈥淲ith perhaps the exception of autism, many clients who are nonverbal or have complex communication needs are likely to have some feeding or swallowing problems,鈥� said Begley. 鈥淵et when we started examining all the device libraries, there was not one script that was preset where we could drop in to say 鈥楾his is how my food needs to be prepared鈥� or 鈥楾hese are my cautionary notes on foods.鈥欌��
Pooling their resources, Pitti and Begley addressed the problem by developing a safe swallowing protocol (SSAE) and, from that, a set of icons called 鈥淪mallTalk Dysphagia,鈥� which is available on AAC devices through Lingraphica and also as an application for the iPod Touch and iPad. By serving as a checklist for caregivers and clinicians whose primary expertise may not be dysphagia, 鈥淪mallTalk Dysphagia鈥� ensures that a patient鈥檚 mealtime and swallowing-related concerns are met.
Pitti and Begley鈥檚 new application, based on their safe swallowing protocol, covers nine categories:鈥� level of assistance needed for meals鈥� pre-meal preparations鈥� need for adaptive equipment during mealtime鈥� current diet鈥� current liquids鈥� compensatory treatment techniques鈥� facilitation treatment techniques鈥� medications鈥� end-of-life decisions/advance directives.
鈥淪mallTalk Dysphagia鈥� currently has 54 icons and phrases such as 鈥淚 need chin support鈥� and 鈥淚 need to be sitting upright for a meal鈥� as well as four videos demonstrating more complex concepts. The icons are arranged sequentially to coincide with the start and conclusion of a meal.
A major consideration in creating the icons was making them immediately understandable to patients.
鈥淪ince one of the main populations served by this protocol is people with some sort of neurological event, memory problems can often be an issue,鈥� Pitti said. 鈥淎s a result, we carefully considered what each icon would look like and tried to make it as transparent as possible. The overarching goal was making sure that verbally limited or nonverbal patients have the same decision-making access as a verbal patient.鈥�
鈥淧eople who are verbal can say, 鈥業'm done; I鈥檓 not doing that anymore,鈥欌�� Begley added. 鈥淏eing able to convey that information is equally as important for nonverbal populations. It gives them the opportunity to change their mind. Verbally, you can change your mind in one sentence. But if nonverbal people don鈥檛 have that option readily available, a caretaker who is not familiar with dysphagia might not anticipate they want to say that.鈥�
Because quality-of-life and end-of-life issues were also important considerations, Pitti and Begley addressed issues such as alternative feedings, the ability to refuse diet changes or treatment techniques, and the ability to decline a medical procedure or issue advance directives.
鈥淚f patients have the will and ability to do that, we need to give them an avenue for it,鈥� Pitti said. 鈥淚n regard to change or progress, few people stay the same. If they are improving, the icon library at their fingertips needs to be able to allow for that. If they have a degenerative condition and are expected to decline, the device needs a full range of icon options, so they can select what is accurate for that given time鈥攁 regular diet, ground diet or puree diet.鈥�
Pitti and Begley consider the application and SSAE protocol the beginning of a larger undertaking to serve the unique needs of patients who require both AAC- and dysphagia-related care. They hope to design more dysphagia icons, as well as obtain input and collaboration from other speech-language pathologists across all scopes of practice.
Dysphagia icons and videos are available through Lingraphica and iTunes app store at . The cost is 99 cents.
