A scoping review of AAC interventions for children and young adults with simultaneous visual and motor impairments: Clinical and research Implications

Individuals with multiple disabilities are among the most challenging to serve and AAC teams often lack direction in determining effective interventions. The purpose of this scoping review was to summarize the research evidence on AAC interventions for individuals with complex communication needs and simultaneous motor, and visual impairments as part of their multiple disabilities; to consider implications for practice; and to determine gaps and directions for future research. A total of 27 studies were identified and reviewed, involving 55 unique participants with multiple disabilities. Most studies focused on direct intervention to increase requesting or choice-making, with little focus on social communication. Only two studies focused on training communication partners. Results indicated that AAC interventions can be highly effective to increase communication for individuals with multiple disabilities. However, there is an urgent need for increased rigor and more detailed participant information in future AAC intervention research with this population. Future research should investigate AAC intervention to improve social communication and increase language development, not just expression of needs and wants. Future research should focus on the needs of individuals with multiple disabilities from culturally and linguistically diverse backgrounds and on implementation of AAC within natural environments.

From assistive to inclusive? A systematic review of the uses and effects of technology to support people with pervasive support needs

BACKGROUND

Although particular technologies can enhance the quality of life (QoL) of people with profound intellectual and multiple disabilities (we use the term pervasive support needs), their objectives and outcomes are understudied. A systematic literature review was therefore conducted to explore this topic.

METHOD

A search of four databases yielded 64 studies. Data were extracted on their general characteristics, methods and sample characteristics as well as the technology types, QoL domains and application within ecological systems. A narrative synthesis was subsequently developed.

RESULTS

Most of the studies applied assistive technology (AT) and focused on personal development and self-determination on an individual level.

CONCLUSIONS

Technology can enhance the QoL of people with pervasive support needs. There are indications that although MT and UD-based technology are used in practice, few studies have examined these technologies. Therefore, there is a knowledge gap regarding the kinds of technology that are used in practice.

Assistive technology for communication of older adults: a systematic review

OBJECTIVE

Describe the use of assistive technology to enhance communication opportunities for older adults.

METHODS

A systematic review was conducted in two databases, PubMed and Web of Science, by using two different searches in each. The search was limited to original articles, in English language, including people aged 60 years and older that used any type of assistive technology for communication. The articles found in the initial search were filtered by title, abstracts and the remaining articles were fully read.

RESULTS

Eighteen studies were included in this review after the reading of full-texts. Most of the studies included apparently healthy participants with communication limitations due to aging related changes and the others included people with some pathology that prevent them from normal communication.

CONCLUSION

Four categories of assistive technology were identified: assistive technology for people with speech problems; robot or videoconferencing systems; Information and Communication Technologies and, other types of assistive technology for communication, such as hearing aids and scrapbooks. Assistive technology for communication of older adults is not only used by people with disabilities that prevent them from usual communication. They are mostly for older adults without a pathological communication problem.

Technology to support positive occupational engagement and communication in persons with multiple disabilities

Persons with multiple (intellectual and sensory-motor) disabilities can have serious difficulties managing their independent engagement in leisure activities and communication, particularly with partners not present in their immediate environment.

This study assessed two versions of a technology-aided program (involving a computer system to present leisure and communication options and a microswitch to choose among them) with four participants with multiple disabilities. Two participants used the first version of the program, which allowed them to choose among leisure (music) options. The other two participants used the second version of the program, which allowed them to choose among leisure (music and videos) and communication (telephone calls) options. Each program version was implemented according to a non-concurrent multiple baseline design across participants.

Data showed that both program versions were successful in helping the participants achieve the objectives pursued, that is, choose and access leisure or leisure and communication options independently.

Technology-aided programs can enable persons with multiple disabilities to manage positive occupational engagement and communication.

Encouraging obese students with intellectual disabilities to engage in pedaling an exercise bike by using an air mouse combined with preferred environmental stimulation

This study extended research into the application of high-tech products in the field of special education, using a standard air mouse with a newly developed pedal detection program (PDP) software. PDP is a new software program used to turn a standard air mouse into a pedal detector in order to evaluate whether two obese students with intellectual disabilities (ID) would be able to actively perform the activity of pedaling an exercise bike in order to control their preferred environmental stimulation. This study was performed according to an ABAB design. The data showed that both participants had more willingness to engage in the pedaling activity to activate the environmental stimulation in the intervention phases than in the baseline phase. The practical and developmental implications of the findings are discussed.

Using an ABAB design we found substantial increases in both participants' target responses (i.e. the performance of occupational activities) to activate the control system to produce environmental stimulation during intervention phrases. The practical and developmental implications of the findings are discussed.

Result showed that both participants significantly increased their time duration of maintaining a static limb posture (TDMSLP) to activate the control system in order to produce environmental stimulation in the intervention phases. Practical and developmental implications of the findings are discussed.

Assisting Two Children with Multiple Disabilities and Minimal Motor Skills Control Environmental Stimuli with Thumb Poke Through a Trackball

Background: Microswitches are the most commonly used input device for people with multiple disabilities to control environmental stimulation. However, little is known about adopting the commercial trackball with a revised trackball driver as a more feasible input device. Aims: To assess whether two children with profound multiple disabilities and minimal motor skills would be able to control environmental stimulation using thumb poke ability through cordless trackballs installed with a newly developed mouse driver (i.e. a new mouse driver replacing a standard mouse driver, turning a trackball mouse into a precise thumb poke detector). Method: An ABAB design and a 2-month post-intervention check were adopted to perform the study. Results: Data showed that the two children improved significantly in their target response (thumb poke) to activate the control system to produce environmental stimuli during the B (intervention) phases. This performance was maintained at the post-intervention check. Conclusions: The use of thumb poke in connection with a trackball allowed the children with multiple disabilities and minimal motor skills to increase their level of response and stimulation control.

Data showed that both participants significantly increased their target response (hand swing) to activate the control system to produce environmental stimulation during the B (intervention) phases. This performance was maintained at the post-intervention check. Practical and developmental implications of the findings were discussed.
