Abstract
This study assessed the possibility of replacing head and hand responses (no longer feasible) with minimal movements within the microswitch-based program of an adolescent with deteriorating motor condition and multiple disabilities. The new movements, i.e., eye- and mouth-opening, were introduced individually and then combined through the simultaneous availability of the related microswitches. Data showed the participant acquired the new movements (responses) successfully and retained them at a 2-mo. postintervention check. Mood improvements, i.e., increases in indices of happiness, also occurred through the program. The conclusion was that a person with deteriorating motor conditions may be able to revitalize a microswitch-based occupational program and retain a constructive engagement if new, feasible responses are identified.

Abstract
This study assessed small hand-closure movements as a potential response for microswitch activation with two participants with profound multiple disabilities of 5.2 and 20.6 yr. of age. The microswitch consisted of a two-membrane thin pad fixed to the palm of the hand and a control system. The outer membrane (the one facing the fingers) was a touch-sensitive layer; the inner membrane was activated if the participant applied a pressure of over 20 gm. The activation of either membrane triggered an electronic control system, which in turn activated one or more preferred stimuli for 6 sec. except in baseline phases. Each participant received an ABAB sequence, in which A represented baseline and B intervention phases, and a 1-mo. postintervention check. Analysis showed both participants increased their responding during the intervention phases and maintained that responding at the postintervention check. Implications of the findings are discussed.

Abstract
This study proposed the use of assistive technology (AT) to promote communication and leisure opportunities by three children with traumatic brain injury (TBI). Furthermore, it assessed the effects of such technology on the indices of positive participation and provided a social validation procedure. Three children emerged from a minimal conscious state and presenting extensive motor disabilities were involved. The intervention program allowed the participants to request and to choice preferred items independently and to perform literacy through a keyboard emulator. A multiple probe design across behaviors with post-intervention check was employed. Outcome measures were correct requests, understandable words, intervals with positive participation, and scores of social validation assessment. Request and choice behaviors and literacy improved significantly during intervention phases. During post-intervention check, all participants consolidated their performance. Moreover, indices of positive participation increased during intervention phases. Scores of social validation assessment showed that the combination of both behaviors was preferable to the same considered separately. AT program showed to be suitable for promoting constructive engagement and literacy behaviors by children with TBI. Future research is needed to generalize this data to a larger sample and to develop new technology for people with different levels of disabilities due to TBI.

Abstract
The study describes the adaptive-switch performances of 8 adults with severe multiple impairments. Each was given a series of progressively more difficult discrimination tasks that, if solved, would require the participant to close the switch to activate a device that was not operating or to stay away from the switch if the device was operating. Then in a 2-choice format, a preference test was conducted by providing 2 devices simultaneously that could be activated or deactivated by closure or release of the switch. Finally, a preferred device was activated and then surreptitiously deactivated. Switch closures in this contingency activated a speech-generating device that played the message, "Help me." All 8 participants learned to control devices using their adaptive switch, but only 4 participants learned to make a request for help. Reasons for the different performances across learners and nonlearners are discussed.

Abstract
A technology-based program to promote independent choice behaviors by three children with cerebral palsy and multiple disabilities was assessed. The program was based on learning principles and assistive technology (i.e., customized input devices/sensors, personal computers, screening of preferred stimuli according to a binomial criterion). The first purpose of the present study was to provide the participants with a new set-up of assistive technology and to allow them to choose among three categories (i.e., food, beverage and leisure), and to request a specific item out of four in each category, adopting a procedure that minimized (according to a conditional probability criterion) unintentional choices. The second aim of the study was to carry out the effects of the program on detectable mood signs (i.e., happiness index). The study was conducted according to an ABAB sequence with a subsequent post intervention check for each participant. The results showed an increase of engagement and of the happiness index during intervention phases. Psychological as well as educational implications were discussed.

Abstract
BACKGROUND A camera-based microswitch technology was recently developed to monitor small facial responses of persons with multiple disabilities and allow those responses to control environmental stimulation. This study assessed such a technology with 2 new participants using slight variations of previous responses. METHOD The technology involved a computer with a CPU using a 2GHz clock, a USB video camera with 16-mm lens, and special software. Small colour spots were used under the lower lip of one participant and on the eyelid of the other participant to aid the camera and computer to detect their mouth and eyelid responses. The study involved an ABAB design and included a 3-week post-intervention check. RESULTS The participants' mouth and eyelid responses increased during the intervention (B) phases and post-intervention check (i.e., when the technology allowed them to control stimulation). CONCLUSIONS Camera-based microswitch technology can help persons with multiple disabilities control stimulation with small responses.

Abstract
This study assessed a new microswitch arrangement for eyelid responses using an optic sensor placed above the cheekbone and a small sticker on the person's eyelid. This new arrangement, which was designed to avoid interference of the microswitch with the person's visual functioning, was tested on three adults with acquired brain injury and multiple (consciousness, communication, and motor) disabilities. The study was carried out according to a non-concurrent multiple baseline design across participants. Data showed the new microswitch arrangement was suitable for all three participants, who increased their responding during the intervention phase of the study when their responses allowed them to access preferred stimulation. Practical implications of the findings are discussed.

Abstract
These two studies assessed camera-based microswitch technology for eyelid and mouth responses of two persons with profound multiple disabilities and minimal motor behavior. This technology, in contrast with the traditional optic microswitches used for those responses, did not require support frames on the participants' face but only small color marks. The person involved in Study I had previously used optic sensors fixed on an eyeglasses' frame for detecting his eyelid- and mouth-opening responses. However, a deterioration of his head posture was making the correct location/use of this frame progressively more difficult. The person involved in Study II had previously been selected for a program relying on eyelid-closure responses and an optic sensor. Such a program however appeared difficult to implement given his sideward lying position and dystonic head movements. The new technology could be satisfactorily applied with both participants using mouth and eyelid opening with the first participant and eyelid closures with the second participant. Both participants had large increases in responding during the intervention periods (i.e., when their responses were followed by preferred stimulation). The findings are discussed in relation to the role of the new technology in helping persons with multiple disabilities and minimal motor behavior.

Abstract
This paper presents an overview of the studies directed at helping post-coma persons with minimally conscious state improve their adaptive behavior. Twenty-one studies were identified for the 2000-2010 period (i.e., a period in which an intense debate has occurred about diagnostic, rehabilitative, prognostic, and ethical issues concerning people with severe acquired brain injury). Three of the 21 studies involved transcortical magnetic or deep brain stimulation. Six studies focused on the provision of multisensory stimulation or music therapy. The remaining 12 studies involved the use of response-related (contingent) stimulation and assistive technology. The outcomes of the studies, which were generally reported as positive, were discussed in terms of (a) the size (quantitative relevance) of the changes obtained, (b) the credibility/reliability of the changes, in light of the methodological conditions of the studies, and (c) the level of engagement and interaction involvement of the participants. Relevant issues for future research were also examined.

Abstract
OBJECTIVE To evaluate the viability of technology-assisted learning setups for undertaking assessment and providing intervention to persons in vegetative state. METHOD Study I investigated whether three persons with a diagnosis of vegetative state could associate eye blinking or hand closure responses with contingent, positive stimulation, thus increasing their frequencies (showing signs of learning). Study II extended the learning process (introducing a new response and new stimuli) for one of the participants of Study I. RESULTS Two of the participants of Study I succeeded in increasing their responses, indicating signs of learning. Study II showed that the participant (one of the two succeeding in Study I) acquired a new response to access new stimuli and could alternate this response with the one acquired in Study I. CONCLUSION Learning might represent a basic level of knowledge and consciousness. Detecting signs of learning might help modify a previous diagnosis of vegetative state and support intervention/rehabilitation efforts.

Abstract
A man with multiple disabilities was taught to use single vs repeated performance of simple motor schemes as different responses. Specifically, single and double emissions of a finger movement served as two separate responses, which allowed direct access to different environmental stimuli via microswitch technology. Single and double emissions of a head movement served as two additional responses, which allowed interaction with two different caregivers who were called via voice output communication aids (VOCAs). The results showed that the man, who had pervasive motor impairment, acquired the four responses available and seemed to use them purposefully. The implications of this approach to increase the response options of persons with few controllable motor schemes were discussed.

Abstract
Intervention programs, based on learning principles and assistive technology, were assessed in two studies with two post-coma men with minimally conscious state and pervasive motor disabilities. Study I assessed a program that included (a) an optic microswitch, activated via double blinking, which allowed a man direct access to brief music intervals, and (b) a voice output communication aid (VOCA) with two channels, activated via different hand-closure movements, which allowed the man to call his mother and a research assistant who provided stimulation events. Study II assessed a program that included (a) a pressure microswitch, activated via head movements, which allowed a man direct access to video-clips and music, and (b) a VOCA device, activated via prolonged eyelid closure, which allowed the man to call the caregiver (i.e., a research assistant) who provided attention and sung to him. Each of the two participants had significant increases in both microswitch- and VOCA-related responses during the intervention phases of the studies. Moreover, purposeful choice seemed to occur between the two VOCA responses in Study I. Implications of the findings for improving the situation of post-coma persons with minimally conscious state and pervasive motor disabilities are discussed.

Abstract
Post-coma persons in an apparent condition of vegetative state and pervasive motor impairment pose serious problems in terms of assessment and intervention options. A technology-based learning assessment procedure might serve for them as a diagnostic supplement with possible implications for rehabilitation intervention. The learning assessment procedure adopted in this study relied on hand-closure and eye-blinking responses and on microswitch technology to detect such responses and to present stimuli. Three participants were involved in the study. The technology consisted of a touch/pressure sensor fixed on the hand or an optic sensor mounted on an eyeglasses' frame, which were combined with a control system linked to stimulus sources. The study adopted an ABABCB sequence, in which A represented baseline periods, B intervention periods with stimuli contingent on the responses, and C a control condition with stimuli presented non-contingently. Data showed that the level of responding during the B phases was significantly higher than the levels observed during the A phases as well as the C phase for two of the three participants (i.e., indicating clear signs of learning by them). Learning might be deemed to represent basic levels of knowledge/consciousness. Thus, detecting signs of learning might help one revise a previous diagnosis of vegetative state with wide implications for rehabilitation perspectives.

Abstract
The first of these two studies assessed whether 11 participants with multiple disabilities of 5.3-18.2 (M=10.7) years of age would succeed in combining a microswitch for accessing preferred environmental stimuli and a Voice Output Communication Aid (VOCA) for requesting social contact. The second study conducted a social validation assessment of the aforementioned microswitch-VOCA combination. Data showed that all participants learned to use the microswitch and the VOCA. Moreover, the 10 participants, who received a 1-month post-intervention check, largely maintained their responding. The social validation assessment indicated that the raters (i.e., 110 university psychology students) favored the combination of microswitch and VOCA over the microswitch or the VOCA alone, and hypothetical combinations of microswitches or VOCAs.

Abstract
A diagnosis of vegetative state represents a serious predicament, which basically precludes/minimizes rehabilitation perspectives. Reliability of the assessment approach in these situations is of paramount importance, but not easy to achieve. In recent studies, a learning assessment procedure has been suggested as a supplement in the diagnostic process and assessed with eight patients. The procedure involves an ABABCB sequence in which A represents baseline phases with no stimulation available, B intervention phases with stimuli delivered contingently on target responses, and C a control condition. This condition involves stimulation presented non-contingently. The patients' ability to associate responding with environmental stimuli and thus increase such responding during the B phases, and reduce it during the A and C phases, may be considered a sign of learning. Learning might be viewed as representative of forms of concrete knowledge and presumably basic levels of consciousness. Preliminary results indicate that (a) signs of learning may appear in patients with a previous diagnosis of vegetative state and (b) the presence of those signs may require a revision of their diagnostic label and a reappraisal of their rehabilitation perspectives.

Abstract
The first of these two studies extended preliminary evidence on the use of technology-based programs for enabling students with severe and profound multiple disabilities to choose and access environmental stimuli on their own. Each of the three participants had two microswitches linked to specific sets of stimuli through a computer system. The activation of one of the microswitches triggered the computer system to present a sample of one of the stimuli. If the student chose it, the computer system turned it on for a specific time interval. The second study tested a new technology that allowed the students to choose and access the chosen stimuli with the involvement of the caregiver. The two participants had three microswitches linked to a computer system. The participants' choice of a stimulus alerted the caregiver who then got involved in the stimulation process. The results of both studies showed that the participants learned to activate the basic microswitches consistently, had high percentages of choice for the stimulus samples presented by the computer but with wide differences across stimuli, and largely maintained this performance at a 2-month post-intervention check. These findings were analyzed in terms of the usability of the two types of programs, the role they may play within educational and living contexts, and their innovative technical dimensions.

Abstract
PURPOSE A learning setup was arranged for an adolescent with profound multiple disabilities and a diagnosis of vegetative state. Signs of learning by the adolescent would underline an improvement in his immediate situation with potential implications for his general prospect, and could help revise his diagnosis. METHOD The response adopted in the learning setup was forehead skin movement. The microswitch technology used for detecting such a response consisted of (a) an optic sensor (i.e., barcode reader), (b) a small tag with horizontal bars attached to the participant's forehead, and (c) an electronic control system that activated stimuli in relation to the participant's forehead responses. The study followed an ABABACAB sequence, in which A represented baseline periods, B intervention periods with stimuli contingent on the response, and C a control condition with stimuli presented non-contingently. RESULTS Data showed that the level of responding during the B phases was significantly higher than the levels observed during the A phases as well as the C phase, indicating clear signs of learning. CONCLUSIONS Intervention strategies based on a learning format and suitable technology might be useful to improve the situation and prospect of persons with profound multiple disabilities and a diagnosis of vegetative state.

Abstract
A recent study has shown that microswitch clusters (i.e., combinations of microswitches) and contingent stimulation could be used to increase adaptive responding and reduce dystonic/spastic behavior in two children with multiple disabilities [Lancioni, G. E., Singh, N. N., Oliva, D., Scalini, L., & Groeneweg, J. (2003). Microswitch clusters to enhance non-spastic response schemes with students with multiple disabilities. Disability and Rehabilitation, 25, 301-304]. The present study was an attempt to replicate the aforementioned study with two boys with multiple disabilities. The adaptive responses selected for the boys consisted of pushing an object with the hand or the back. The dystonic/spastic behavior consisted of body arching (i.e., pushing belly and stomach forward) and leg stretching for the two boys, respectively. Initially, the boys received preferred stimulation for all hand- and back-pushing responses. Subsequently, the stimulation followed only the responses that occurred free from the dystonic/spastic behavior. The results showed that both boys increased the frequency of adaptive responses, learned to perform these responses free from the dystonic/spastic behavior, and maintained this improved performance during a 2-month post-intervention check.

Abstract
The present study assessed the use of a voice-detecting sensor interfaced with a scanning keyboard emulator to allow two boys with extensive motor disabilities to write. Specifically, the study (a) compared the effects of the voice-detecting sensor with those of a familiar pressure sensor on the boys' writing time, (b) checked which of the sensors the boys preferred, and (c) conducted a social validation assessment of the boys' performance with the two sensors, employing psychology students as raters. The difference in the boys' overall mean writing time per letter across sensors was, by the end of the study, about 1.5s. This difference favored the pressure sensor for one of the boys and the voice-detecting sensor for the other boy. Both boys showed preference for the voice-detecting sensor. Moreover, the psychology students involved in the social validation assessment indicated that such sensor was more satisfactory, suitable, and educationally relevant than the pressure sensor, and represented the solution that they as raters supported more.

Abstract
BACKGROUND Intervention strategies, based on learning principles and assistive technology, were assessed with four post-coma persons with minimally conscious state and pervasive motor disabilities. METHOD The first study taught a man to access environmental stimulation through a response-microswitch combination and another man to access environmental stimulation and request social contact through responses combined with a microswitch or a Voice Output Communication Aid (VOCA). The second study taught a man to access two forms of environmental stimulation via two response-microswitch combinations and another man to request two forms of contact via two response-VOCA combinations. RESULTS Data showed that all participants had significant increases in response levels (independent of whether the responses were combined with microswitch or VOCA devices) during the intervention phases of the studies. CONCLUSION Intervention strategies based on learning principles and technology may be largely helpful for persons with minimally conscious state and pervasive motor disabilities.

Abstract
The study was an effort to help a girl with multiple disabilities increase object manipulation responses and reduce hand mouthing, carried out according to an ABAB sequence (in which A represented baseline phases; B, treatment phases) and including a 3-month follow-up. During the baseline phases, a microswitch cluster (i.e., a combination of microswitches) was used to monitor the girl's object manipulation responses and hand mouthing. Indices of happiness were also recorded. During the treatment phases and follow-up, the microswitch cluster was combined with the use of preferred stimuli for object manipulation responses. The stimuli lasted an 8-s period at each response if the girl remained free from hand mouthing through that period, but were interrupted if hand mouthing appeared. The results show that the girl increased object manipulation responses, learned to refrain from hand mouthing for most of the session time, maintained this performance over time, and showed an increase in indices of happiness.

Abstract
Persons with multiple disabilities are often unable to interact with their environment due to their limited response repertoire. Microswitch programs are designed to help them control environmental events, generally preferred stimulation, through simple (feasible) responses. To make microswitch programs a more widely usable and relevant resource for intervention with these persons, a number of new developments were pursued in recent years. This paper examines three of those developments as specifically addressed in our research activity, namely, (a) assessment of new, nontypical responses and matching microswitches, (b) fostering of multiple responses and exercise of choice, and (c) targeting of habilitative and clinical (therapeutic) objectives. The encouraging outcomes of these developments are reviewed in relation to their potentially wide implications for daily practice and the need of additional developments in the area.

Abstract
BACKGROUND Direct access to environmental stimuli and opportunity to ask for social contact/attention may be considered highly relevant objectives for persons with multiple disabilities. We assessed the possibility of enabling three of these persons (two children and one adolescent) to combine two microswitches (for accessing environmental stimuli) and a Voice Output Communication Aid (VOCA), which allowed them to ask for caregiver's attention. METHODS Initially, the participants were required to use each of the two microswitches individually and then together. Thereafter, they were taught to use the VOCA. Eventually, the VOCA was available together with the microswitches, and the participants could use any of the three. RESULTS The results, which support preliminary data on this topic, showed that all participants (1) were able to operate the two microswitches as well as the VOCA; and (2) used all three of them consistently when they were simultaneously available. CONCLUSIONS Teaching persons with multiple disabilities to combine a VOCA with conventional microswitches may enrich their general input, emphasize their active social role and eventually enhance their social image.

Abstract
Persons with severe spastic tetraparesis and minimal motor behavior may be confined to a wheelchair or bed and have virtually no chances of constructive engagement with their immediate environment. A possible way to modify this situation may involve the use of technology. The present study (a) assessed specific technology to enable a young adult to manage his leisure television engagement independently and (b) carried out a social validation assessment of the technology-supported performance involving 90 teacher trainees as raters. The intervention period with the new technology included 67 sessions, during which the participant performed independently 392 of the 408 television-management responses, i.e., turning on the television, finding a channel with a preferred program, setting the volume, and turning off the television. He also indicated preference for using the technology as opposed to not using it. The raters provided relatively high (positive) scores for the technology-supported performance compared to the baseline performance. Implications of the findings are discussed.

Abstract
This paper provides an overview of the literature dealing with the use of the Picture Exchange Communication System (PECS) and voice output communication aids (VOCAs) for promoting the performance of requests by students with developmental disabilities. Computerized and manual searches were carried out to identify the studies published during the last 15 years (i.e., the period between 1992 and 2006 during which PECS and VOCA approaches became popular). Thirty-seven studies were identified and then divided into three groups concerning the use of the PECS or equivalents, the use of VOCAs or equivalents, and the comparison of both these approaches, respectively. Of the 173 students involved in studies using the PECS or equivalents only three could be considered failures, while a fourth one did not progress in the program due to illness. Similarly, of the 39 students who used VOCAs or equivalents only three could be considered failures, while one was partly successful. Finally, of the 11 students involved in the comparisons between PECS and VOCAs none could be classified as a failure. The results are very encouraging but methodological concerns and the relatively limited use of the systems in terms of request items and request opportunities suggest caution. Caution may also be needed in interpreting the reported similarities between the two systems in usability and effectiveness.

Abstract
Persons with multiple disabilities and minimal motor behavior may be unable to use available microswitch technology to control environmental stimuli. For these persons, one may need to rely on small motor expressions (as responses) and new, matching microswitch technology to ensure a successful outcome. In the present study, a small movement of the forehead skin was selected as the response for two participants (ages 6.5 and 14.2 years) with profound multiple disabilities. The microswitch technology included (a) an optic sensor, i.e., barcode reader, (b) a small tag with horizontal bars attached to the participants' forehead, and (c) an electronic control system which activated stimuli in relation to response occurrence. Movement of the forehead skin shifted up or down the tag with bars and this shifting, if greater than a preset limit and therefore recorded as a response, led to the activation of the control system. Each participant received an ABAB sequence, in which A represented baseline and B intervention phases, and a 6-wk. postintervention check. Analysis showed both participants increased their responding during the intervention phases and maintained that responding at the postintervention check. Implications of the findings were discussed.

Abstract
This study extended the evaluation of microswitch technology (i.e., a position sensor and an optic device), recently introduced for chin and eyelid responses, with two new participants with profound multiple disabilities. The participants were girls of 12.5 and 4.0 years of age who did not possess any specific response that they could profitably use in their environment. The study was conducted according to an ABAB design with a 3-week postintervention check. The results showed that both participants increased their level of responding during the intervention phases and postintervention check compared to the baseline phases. This positive outcome was discussed in terms of (a) the apparent suitability of the technology and responses used in the study, (b) the beneficial implications for the participants, and (c) new developments in the area.
