Technology-assisted programmes to promote leisure engagement in persons with acquired brain injury and profound multiple disabilities: two case studies

Technology-aided leisure and communication: Opportunities for persons with advanced Parkinson's disease

OBJECTIVE

This study investigated whether simple technology-aided programs could be used to promote leisure and communication engagement in three persons with advanced Parkinson's disease.

METHOD

The programs included music and video options, which were combined with (a) text messaging and telephone calls for the first participant, (b) verbal statements/requests, text messaging, and reading for the second participant, and (c) verbal statements/requests and prayers for the third participant. The participants could activate those options via hand movement or vocal emission and specific microswitches.

RESULTS

All three participants were successful in activating the options available. The mean cumulative frequencies of option activations were about five per 15-min session for the first two participants and about four per 10-min session for the third participant.

CONCLUSION

The results were considered encouraging and relevant given the limited amount of evidence available on helping persons with advanced Parkinson's disease with leisure and communication.

A Systematic Review of the Efficacy of Community-based, Leisure/Social Activity Programmes for People with Traumatic Brain Injury

Background: Many people who have a severe traumatic brain injury (TBI) are not able to resume employment and consequently experience profound changes in their lifestyle. They have increased amounts of ’spare time’ yet often find it difficult to engage in meaningful activity. Leisure activities are one way in which meaningful activity can be increased.

Aims: This systematic review has two purposes: first, to identify and evaluate the efficacy of community-based interventions for leisure/social activity after TBI, and second to provide details on the types of intervention.

Method: Systematic searches were conducted of Medline, PsycINFO and PsycBITE to October 2014, as well as hand searches of two occupational therapy journals. Inclusion criteria were as follows: peer reviewed journal articles on adults with TBI who had participated in a trial evaluating a community-based intervention specifically targeting leisure/social activity. All research methodologies using primary studies that provided empirical, quantitative data were considered. Scientific quality of the studies was evaluated using the PEDro Scale for controlled trials and the Risk of Bias in N-of-1 Trials Scale for single-case designs.

Results: Two independent raters screened 196 abstracts, resulting in nine articles that met selection criteria. Data were then independently extracted by the raters. Four of the nine studies used a control condition in their research design (two randomised controlled trials, one controlled but non-randomised study, and one single-case experiment using a changing criterion design). Two of the studies conducted between-group analyses with significant treatment effects for mood and quality of life using active leisure programmes (Tai Chi Qigong and a combined programme of outdoor adventure experiences and goal setting respectively). Intervention programmes identified in the review were then grouped and described according to the approach or model used, including active leisure programmes, social peer mentoring, individual brokered leisure services and a therapeutic recreation model. Additional intervention models and approaches that did not result directly from the systematic review were also described because they provide information on the current approaches used in practice (Clubhouse model and leisure education programmes in the stroke population).

Conclusions: There is some evidence for the effectiveness of community-based interventions for leisure/social activity for people who have had a TBI to improve mood and quality of life. The conclusions of this review are that the interventions for this area need to be planned and specific, structured and goal-driven, intensive and conducted over a period of months.

Technology-aided programs for post-coma patients emerged from or in a minimally conscious state

Post-coma persons in a minimally conscious state (MCS) or emerged/emerging from such state (E-MCS), who are affected by extensive motor impairment and lack of speech, may develop an active role and interact with their environment with the help of technology-aided intervention programs. Although a number of studies have been conducted in this area during the last few years, new evidence about the efficacy of those programs is warranted. These three studies were an effort in that direction. Study I assessed a technology-aided program to enable six MCS participants to access preferred environmental stimulation independently. Studies II and III assessed technology-aided programs to enable six E-MCS participants to make choices. In Study II, three of those participants were led to choose among leisure and social stimuli, and caregiver interventions automatically presented to them. In Study III, the remaining three participants were led to choose (a) among general stimulus/intervention options (e.g., songs, video-recordings of family members, and caregiver interventions); and then (b) among variants of those options. The results of all three studies were largely positive with substantial increases of independent stimulation access for the participants of Study I and independent choice behavior for the participants of Studies II and III. The results were analyzed in relation to previous data and in terms of their implications for daily contexts working with MCS and E-MCS persons affected by multiple disabilities.

Occupation and communication programs for post-coma persons with or without consciousness disorders who show extensive motor impairment and lack of speech

These two studies were aimed at extending the assessment of technology-aided programs for post-coma persons with extensive motor impairment and lack of speech. Specifically, Study I assessed a new program arrangement, in which stimulation access and caregiver attention could be obtained with variations of the same response (i.e., single- versus double-hand closure) by three participants who were diagnosed at the upper level of the minimally conscious state at the start of the study. Study II was aimed at enabling two persons who had emerged from a minimally conscious state to engage in leisure activities, listen to audio-recordings of family members, and send and receive messages. The responses selected for these participants were hand pressure and eyelid closure, respectively. The results of both studies were positive. The participants of Study I increased their responding to increase their stimulation input and caregiver interaction. The participants of Study II managed to successfully select all the options the program included (i.e., the leisure options, as well as the family and communication options). General implications of the programs and the related technology packages for intervention with post-coma persons with multiple disabilities are discussed.

Technology to help persons with extensive neuro-motor impairment and lack of speech with their leisure occupation and communication

These two studies were aimed at extending the assessment of technology-aided programs to enhance leisure occupation or communication with persons with extensive neuro-motor impairment and lack of speech. Specifically, Study I implemented the program for leisure occupation with two post-stroke patients. Study II implemented the program for communication with two persons affected by amyotrophic lateral sclerosis (ALS). In Study I, a computer system presented the participants with a variety of stimuli. The participants could select/access those stimuli by microswitch activation or could bypass them by abstaining from microswitch responses. In Study II, the participants used a computer-aided telephone system that allowed them to choose via microswitch activation the persons to call. On the computer screen, they also had words and phrases that they could activate during the calls to influence the conversation with the persons called. Data from both studies were largely positive. The post-stroke patients showed high levels of stimulus selection (access) and extended engagement. The patients with ALS were able to make phone calls and to select the words/phrases to influence the conversations. The relevance of technology-aided programs for leisure occupation and communication of persons with extensive multiple disabilities was discussed.

Technology-based intervention programs to promote stimulation control and communication in post-coma persons with different levels of disability

Post-coma persons in a minimally conscious state and with extensive motor impairment or emerging/emerged from such a state, but affected by lack of speech and motor impairment, tend to be passive and isolated. A way to help them develop functional responding to control environmental events and communication involves the use of intervention programs relying on assistive technology. This paper provides an overview of technology-based intervention programs for enabling the participants to (a) access brief periods of stimulation through one or two microswitches, (b) pursue stimulation and social contact through the combination of a microswitch and a sensor connected to a speech generating device (SGD) or through two SGD-related sensors, (c) control stimulation options through computer or radio systems and a microswitch, (d) communicate through modified messaging or telephone systems operated via microswitch, and (e) control combinations of leisure and communication options through computer systems operated via microswitch. Twenty-six studies, involving a total of 52 participants, were included in this paper. The intervention programs were carried out using single-subject methodology, and their outcomes were generally considered positive from the standpoint of the participants and their context. Practical implications of the programs are discussed.

A voice-sensitive microswitch for a man with amyotrophic lateral sclerosis and pervasive motor impairment

OBJECTIVE

To assess a voice-sensitive microswitch for a 67-year-old man with amyotrophic lateral sclerosis (ALS) who had difficulties continuing to use an optic microswitch through small chin movements.

METHOD

The man used the microswitches in combination with a computer-aided program to (a) access preferred songs and videos or make requests, and (b) operate a messaging system to communicate with his wife and sons. To assess the man's performance with the two microswitches, we alternated sessions with one microswitch with sessions with the other.

RESULTS

The man's performance with the new microswitch was apparently more efficient (i.e. he could generally activate the new microswitch with a single attempt while he needed a mean of about two attempts for each activation of the optic microswitch). The man also developed a clear preference for the new microswitch.

CONCLUSION

Technology updates are critical within programs for persons with motor degeneration.

IMPLICATIONS FOR REHABILITATION

A microswitch that can be used efficiently and without effort is critically important for a person with ALS. The microswitch can be used with programs that allow the person to manage leisure stimulus events, request opportunities and/or text messaging communication. The microswitch needs to be updated (changed) in relation to the person's physical deterioration.

Technology-aided leisure and communication opportunities for two post-coma persons emerged from a minimally conscious state and affected by multiple disabilities

This study assessed technology-aided programs for helping two post-coma persons, who had emerged from a minimally conscious state and were affected by multiple disabilities, to (a) engage with leisure stimuli and request caregiver's procedures, (b) send out and listen to text messages for communication with distant partners, and (c) combine leisure engagement and procedure requests with text messaging within the same sessions. The program for leisure engagement and procedure requests relied on the use of a portable computer with commercial software, and a microswitch for the participants' response. The program for text messaging communication involved the use of a portable computer, a GSM modem, a microswitch for the participants' response, and specifically developed software. Results indicated that the participants were successful at each of the three stages of the study, thus providing relevant evidence concerning performance achievements only minimally documented. The implications of the findings in terms of technology and practical opportunities for post-coma persons with multiple disabilities are discussed.

Technology-based programs to support forms of leisure engagement and communication for persons with multiple disabilities: two single-case studies

OBJECTIVE

To extend the assessment of technology-based programs for promoting stimulus choice and staff/caregiver calls or radio operation and text messaging.

METHOD

In Study I, the program involved a portable computer, commercial software, and a microswitch to allow a man with motor impairment and moderate intellectual disability to choose among preferred stimuli (e.g., songs and film clips) and persons to call. In Study II, the programs involved (a) a radio device and an electronic control unit or (b) a net-book computer and a global system for mobile communication. A woman with blindness and moderate intellectual disability used a microswitch to operate the radio or send and listen to text messages.

RESULTS

The participants succeeded in using the technology-aided programs through simple microswitch activations involving partial hand closure (Study I) or hand pressure (Study II).

CONCLUSION

Technology-based programs can provide persons with multiple disabilities relevant leisure and communication opportunities.
