Video Prompting Versus Other Instruction Strategies for Persons With Alzheimer’s Disease

Background/Aim: Two studies assessed the effectiveness of video prompting as a strategy to support persons with mild and moderate Alzheimer’s disease in performing daily activities. Methods: In study I, video prompting was compared to an existing strategy relying on verbal instructions. In study II, video prompting was compared to another existing strategy relying on static pictorial cues. Video prompting and the other strategies were counterbalanced across tasks and participants and compared within alternating treatments designs. Results: Video prompting was effective in all participants. Similarly effective were the other 2 strategies, and only occasional differences between the strategies were reported. Two social validation assessments showed that university psychology students and graduates rated the patients’ performance with video prompting more favorably than their performance with the other strategies. Conclusion: Video prompting may be considered a valuable alternative to the other strategies to support daily activities in persons with Alzheimers disease.

Comparing two different orientation strategies for promoting indoor traveling in people with Alzheimer's disease

The present study compared two different types of orientation strategies: an assistive technology program (AT, i.e., remotely controlled sound/light devices) and a backward chaining procedure (BC) for promoting indoor traveling in four persons with moderate to severe Alzheimers disease (AD). A social validation assessment of the two strategies was also conducted employing undergraduate students as raters. For three out of four participants, AT intervention was more effective than the BC procedure, whilst for the fourth participant the two types of intervention had a comparably satisfying efficacy. A doubly Multivariate Analysis of Variance on social validation assessment data provided generally more positive scores for the AT intervention. These results suggest that AT programs (a) can be valuably employed for restoring and maintaining independence in indoor traveling in people with moderate to severe AD, and (b) might be perceived as preferable to conventional teaching strategies within daily contexts.

Technology-based orientation programs to support indoor travel by persons with moderate Alzheimer's disease: impact assessment and social validation.

The present study (a) extended the assessment of an orientation program involving auditory cues (i.e., verbal messages automatically presented from the destinations) with five patients with Alzheimers disease, (b) compared the effects of this program with those of a program with light cues (i.e., a program in which strobe lights were used instead of the verbal messages) with the same five patients, and (c) conducted a social validation assessment of the two programs with 70 university psychology students employed as social raters. Results confirmed the effectiveness of the program with auditory cues and showed an equally strong impact of the program with light cues with all five patients. The psychology students involved in the social validation assessment provided significantly higher scores for the program involving light cues on a six-item questionnaire. Those scores suggested that this program was perceived as a practically and socially preferable choice. The implications of the findings for daily contexts dealing with patients with Alzheimers disease are discussed.

People with multiple disabilities learn to engage in occupation and work activities with the support of technology-aided programs.

These two studies were aimed at assessing technology-aided programs to help persons with multiple disabilities engage in basic occupation or work activities. Specifically, Study I focused on teaching two participants (an adolescent and an adult) with low vision or total blindness, severe/profound intellectual disabilities, and minimal object interaction to engage in constructive object-manipulation responses. The technology monitored their responses and followed them with brief stimulation periods automatically. Study II focused on teaching three adults with deafness, severe visual impairment, and profound intellectual disabilities to perform a complex activity, that is, to assemble a five-component water pipe. The technology regulated (a) light cues to guide the participants through the workstations containing single pipe components and the carton for completed pipes and (b) stimulation events. The results of both studies were positive. The participants of Study I showed consistent and independent engagement in object-manipulation responses. The participants of Study II showed consistent and independent pipe assembling performance. General implications of the two programs and the related technology packages for intervention with persons with multiple disabilities are discussed.

Persons with Alzheimer's Disease Make Phone Calls Independently Using a Computer-Aided Telephone System

This study assessed whether four patients with a diagnosis of Alzheimers disease could make independent phone calls via a computer-aided telephone system. The study was carried out according to a non-concurrent multiple baseline design across participants. All participants started with baseline during which the telephone system was not available, and continued with intervention in which such system was used. It involved a net-book computer provided with specific software, a global system for mobile communication modem (GSM), a microswitch, and photos of the persons available for the phone calls. All participants learned to use the system and made phone calls independently to a variety of partners such as family members, friends and staff personnel. The positive implications of the system were discussed in relation to previous data in this area and the possibility of helping persons with Alzheimers disease restore an important, instrumental daily ability and engage in communication with distant partners.

Microswitch-aided programs to support physical exercise or adequate ambulation in persons with multiple disabilities

Three microswitch-aided programs were assessed in three single-case studies to enhance physical exercise or ambulation in participants with multiple disabilities. Study I was aimed at helping a woman who tended to have the head bending forward and the arms down to exercise a combination of appropriate head and arms movements. Study II was aimed at promoting ambulation continuity with a man who tended to have ambulation breaks. Study III was aimed at promoting ambulation with appropriate foot position in a girl who usually showed toe walking. The experimental designs of the studies consisted of a multiple probe across responses (Study I), an ABAB sequence (Study II), and an ABABB(1) sequence (Study III). The last phase of each study was followed by a post-intervention check. The microswitches monitored the target responses selected for the participants and triggered a computer system to provide preferred stimuli contingent on those responses during the intervention phases of the studies. Data showed that the programs were effective with each of the participants who learned to exercise head and arms movements, increased ambulation continuity, and acquired high levels of appropriate foot position during ambulation, respectively. The positive performance levels were retained during the post-intervention checks. The discussion focused on (a) the potential of technology-aided programs for persons with multiple disabilities and (b) the need of replication studies to extend the evidence available in the area.

Technological supports to promote choice opportunities by two children with fragile X syndrome and severe to profound developmental disabilities.

This study was aimed at assessing whether technological supports (i.e. optic sensors such as photocells) were successful enabling two boys with fragile X syndrome and severe to profound developmental disabilities to perform occupation and choice opportunities. A second goal of the study was to reduce stereotyped behaviours (i.e. hand mouthing and eye poking) exhibited by the participants. Finally, the third purpose of the study was to verify the rehabilitative effects of the intervention program on the indices of happiness of the participants. The study has been conducted according to a non-concurrent multiple baseline design across participants followed by intervention and cross over phases, where the associations between behavioural responses and environmental consequences were systematically inverted. Moreover, a maintenance phase was assessed. The results demonstrated that the technology is useful to facilitate employment and opportunities of choice, showing a growth of the indices of happiness and a decrease of stereotyped behaviours, from both participants involved. Clinical, practical and psychological implications of the findings are discussed.

Self-regulated music stimulation for persons with Alzheimer's disease: Impact assessment and social validation

Objective: To assess the impact and the social rating of an active music condition (in which 10 patients with Alzheimers disease regulated their music input) vs. a passive music condition. Method: In the active condition, the patients used a simple hand response and a microswitch to activate music stimulation periods. In the passive condition, music stimulation was prearranged and continued through the sessions. The active and passive stimulation sessions were preceded and followed by control (non-stimulation) sessions. Results: The active condition sessions showed an increase in the patients’ indices of positive participation (e.g., singing or music-related movements, and smiles) similar to that observed in the passive condition sessions. Social raters (140 psychology students) favored the active condition on a six-item questionnaire dealing, among others, with conditions’ suitability, respect of patients’ dignity and independence, and practicality. Conclusion: An active music stimulation condition can be viable, effective, and socially preferable.

Persons with multiple disabilities manage positive leisure and communication engagement through a technology-aided program

Objectives: Persons with multiple disabilities may frequently fail to achieve independent leisure engagement and communication with distant partners. The aim of this study was to extend the assessment of a technology-aided program providing support in the aforementioned areas with nine participants with multiple disabilities. Methods: The program involved a computer system presenting leisure and communication options and a microswitch allowing the participants to choose among and access those options. For each participant a specific array of options was available (e.g. songs, comedy videos, and text messages), depending on his or her characteristics and interests. The effects of the program were assessed via an ABAB design. Participants and staff’s opinions about the program were determined through preference checks and interviews. Results: During baseline (without the program), the participants failed to activate/access the options available and thus had no independent option-related engagement time. During intervention, all participants succeeded in using the program, thus accessing the options available independently, and remaining engaged with option-related events for generally 80–90% of the session time. Participants and staff were highly positive about the program. Conclusions: A technology-aided program adapted to the participants’ conditions can be a crucial resource to support their independent leisure and communication engagement.

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

Abstract Background: 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. Methods: 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. Results: 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. Conclusion: Technology-aided programs can enable persons with multiple disabilities to manage positive occupational engagement and communication.
