Assistive Technology for Cognition (ATC) is employed by children with and without disabilities. However, how the ATC is used in everyday life has not been studied. The current study investigated ATC-usage in everyday planning in three groups: 1) children qualifying for Swedish habilitation centers (ID/ASD), 2) children with disability not qualifying for habilitation service (ADHD), and 3) children with typical development (TD). A parental survey was conducted (n = 192) and answers were analyzed with statistical tests and inductive thematic text analysis...

Assistive technologies (ATs) offer capabilities that were previously inaccessible to individuals with severe and profound hearing loss who have no or limited access to hearing aids and implants. This literature review aims to explore existing ATs and identify what still needs to be done. It is found that there is a lack of focus on the overall objectives of ATs. In addition, several other issues are identified, i.e. only a very small number of ATs developed within a research context have led to commercial devices, and there is a predisposition to use the latest expensive technologies and a tendency to avoid designing products universally...

Pressure ulcer interventions are commonly assessed with measures of seating interface pressure, such as peak pressure gradients (PPGs). Decreases in PPG magnitudes may reduce pressure ulcer risk by decreasing tissue deformation and increasing tissue perfusion of at-risk weight-bearing tissues. Changes in PPG directions, which have previously been overlooked in the seating pressure literature, may provide a transient increase in blood flow to at-risk tissues, even if the PPG magnitude and location remain the same...

Students with reading learning disabilities (RLDs) often face struggles in acquiring basic reading abilities, including oral reading fluency. The current study builds on previous work that compared peer-assisted instruction (PAI) to iPad-assisted instruction (IAI) on oral reading fluency, which led to the conclusion that a combined approach may be more effective than either approach alone. A multiple baseline design was used to examine the effectiveness of a combined PAI and IAI approach on oral reading fluency of four 5th grade students with RLD...

Many individuals who require augmentative and alternative communication (AAC) cannot directly select items on computer-based displays. Individuals who also have visual impairments may need to rely on sequential announcement of array choices in auditory scanning. The method is challenging and there is a lack of research to improve this access method. Two potential solutions were tested: using environmental sounds to represent items (e.g., the sound of a clock ticking for a clock) and providing spatial cues regarding the organization of items (e...

Patients with Parkinson's disease suffer from gait disturbances, such as a shuffling and festinating gait, which reduces their quality of life. To circumvent this problem, external visual cues may be applied in gait training to maintain the integrity of motor function. However, conventional training methods, such as transverse lines stuck on the ground, are difficult to adjust and adapt to personalized gait ability. This study proposes a convenient instrumented wheel walker that provides gap adjustable visual cues and selectable projection modes onto the ground with and without motion relative to the user...

The objective of this cross-sectional observational study was to determine whether the use of a microprocessor knee for individuals with an above-the-knee amputation results in improved functional mobility compared to their peers of matched comorbid-health with a non-microprocessor knee, and to inform how this compares to the mobility observed in below-knee prosthesis users. A sample of 450 individuals with lower limb amputation were divided into three groups (n = 150 each). The groups included: nonmicroprocessor knee users (NMPK, age: 57...

This study investigated the features of apps that speech-language pathologists (SLPs) deem to be beneficial for language intervention with children. The study employed an explanatory, sequential mixed-method approach. A self-developed online survey was distributed to SLPs (n = 338) who use apps. This was followed by a semi-structured interview with some participants (n = 16) in order to obtain further insights from the survey. The findings indicated that SLPs view apps as an engaging and motivating tool for therapy to facilitate their intervention goals...

This single-blind randomized pilot study explored feasibility and safety of a self-management fall prevention program, hypothesizing that older persons can comply with this program, while it does not result in more (injurious) falls, or a decrease in mental wellbeing as an adverse effect of being focused on falls prevention. Eighty-six persons, community-dwelling or home for the aged (mean age 80.3 years [SD: 6.3], 56 women (65.1%)) participated. The intervention group measured their gait speed by using the Mobility Feedback Device (MFD) weekly for 6 months...

Accessibility of telecommunication technologies by people who are deaf or hard of hearing has been a critical issue since the invention of the telephone. As both telephone and hearing-aid technologies have evolved, finding compatible solutions has been an ongoing challenge. This paper uses the findings of a longitudinal study to examine the impact of Federal hearing-aid compatibility (HAC) regulations in resolving this problem. The study ran concurrently with the phase-in of Federal Communications Commission regulations requiring that mobile handset manufacturers and wireless service providers make available minimum numbers of cell phones with shielding to reduce electromagnetic interference when cell phones are positioned close to a hearing aid user's ear...
