AbstractObjective: To provide the results of a robotic exoskeleton user satisfaction questionnaire completed by participants utilizing two robotic exoskeletons. Method: Seven individuals with physical disabilities engaged in two exoskeleton-assisted training phases with the REX and the Ekso 1.1 (Ekso), after which they completed a user satisfaction questionnaire. The questionnaire consisted of structured items with a Likert scale, which were averaged and compared, as well as free response questions, which were interpreted thematically. Results: Participants reported some differences in user satisfaction between the two exoskeletons. They indicated higher satisfaction with transferring in and out of the REX and with its appearance and higher satisfaction with the transportability of the Ekso. Expectations for exoskeleton use were relatively similar for the two devices, with some exceptions. Whereas participants indicated that many changes should be made to both exoskeletons, they reported that some were more necessary for the REX and others were more necessary for the Ekso. Participants reported that they would be somewhat likely to use both exoskeletons at home and in the community if they were available. Conclusions: This brief report provides an initial comparison of user satisfaction with two exoskeletons, thereby contributing to the growing body of literature in this area. - Implications for rehabiliation

AbstractObjective: Learning to walk is a major goal of inpatient rehabilitation and robotic exoskeletons may provide a new gait training approach. Our purpose was to determine the feasibility of integrating the Ekso Gait Training device into inpatient rehabilitation in a neurologic population. Design: Longitudinal cohort design and convenience sample including physical therapists trained to use the Ekso Bionics Ekso GT? robotic exoskeleton or inpatients with stroke or SCI. Therapists completed a focus group and survey at baseline and 6 months after initial Ekso training. Patients completed a survey indicating their satisfaction with using the Ekso. Results: Twenty-five patients used the Ekso an average of 4.5 sessions during their 38.5-day rehabilitation stay. Survey and focus group feedback revealed that therapists encountered measurement difficulties with the Ekso and limited treatment time influencing effectiveness of usage. After 6 months, therapists reported an improvement in feasibility. Patients tolerated Ekso sessions well, without any complications or adverse incidents, and reported improved mobility post session. Conclusion: Integrating Ekso gait training into clinical practice was not seamless but appears feasible. Barriers were addressed within the rehabilitation team and received administrative support in a process lasting several months. Patients enjoyed walking in Ekso and felt secure within the device. - Implications for rehabilitation
Integrating Ekso gait training into clinical practice during inpatient rehabilitation is feasible. Overcoming barriers to implementation required administrative support and clinician persistence over several months. Patients tolerated Ekso sessions well, without any complications or adverse incidents. 相似文献

Aim: The main objectives of this study were to quantify clients’ satisfaction and perception upon completion of a locomotor training program with an overground robotic exoskeleton. Methods: A group of 14 wheelchair users with a spinal cord injury, who finished a 6–8-week locomotor training program with the robotic exoskeleton (18 training sessions), were invited to complete a web-based electronic questionnaire. This questionnaire encompassed 41 statements organized around seven key domains: overall satisfaction related to the training program, satisfaction related to the overground robotic exoskeleton, satisfaction related to the program attributes, perceived learnability, perceived health benefits and risks and perceived motivation to engage in physical activity. Each statement was rated using a visual analogue scale ranging from “0?=?totally disagree” to “100?=?completely agree”. Results: Overall, respondents unanimously considered themselves satisfied with the locomotor training program with the robotic exoskeleton (95.7?±?0.7%) and provided positive feedback about the robotic exoskeleton itself (82.3?±?6.9%), the attributes of the locomotor training program (84.5?±?6.9%) and their ability to learn to perform sit–stand transfers and walk with the robotic exoskeleton (79.6?±?17%). Respondents perceived some health benefits (67.9?±?16.7%) and have reported no fear of developing secondary complications or of potential risk for themselves linked to the use of the robotic exoskeleton (16.7?±?8.2%). At the end of the program, respondents felt motivated to engage in a regular physical activity program (91.3?±?0.1%). Conclusion: This study provides new insights on satisfaction and perceptions of wheelchair users while also confirming the relevance to continue to improve such technologies, and informing the development of future clinical trials. - Implications for Rehabilitation
All long-term manual wheelchair users with a spinal cord injury who participated in the study are unanimously satisfied upon completion of a 6–8-week locomotor training program with the robotic exoskeleton and would recommend the program to their peers. All long-term manual wheelchair users with a spinal cord injury who participated in the study offered positive feedback about the robotic exoskeleton itself and feel it is easy to learn to perform sit–stand transfers and walk with the robotic exoskeleton. All long-term manual wheelchair users with a spinal cord injury who participated in the study predominantly perceived improvements in their overall health status, upper limb strength and endurance as well as in their sleep and psychological well-being upon completion of a 6–8-week locomotor training program with the robotic exoskeleton. All long-term manual wheelchair users with a spinal cord injury who participated in the study unanimously felt motivated to engage in a regular physical activity program adapted to their condition and most of them do plan to continue to participate in moderate-to-strenuous physical exercise. Additional research on clients’ perspectives, especially satisfaction with the overground exoskeleton and locomotor training program attributes, is needed. 相似文献

AbstractPurpose: To describe appraisals of robotic exoskeletons for locomotion by potential users with spinal cord injuries, their perceptions of device benefits and limitations, and recommendations for manufacturers and therapists regarding device use. Materials and methods: We conducted focus groups at three regional rehabilitation hospitals and used thematic analysis to define themes. Results: Across four focus groups, 35 adults participated; they were predominantly middle-aged, male, and diverse in terms of race and ethnicity, well educated, and not working. Participants had been living with SCI an average of two decades. Most participants were aware of exoskeletons. Some were enthusiastic about the usability of the devices while others were more circumspect. They had many questions about device affordability and usability, and were discerning in their appraisal of benefits and suitability to their particular circumstances. They reflected on device cost, the need for caregiver assistance, use of hands, and environmental considerations. They weighed the functional benefits relative to the cost of preferred activities. Their recommendations focused on cost, battery life, and independent use. Conclusions: Potential users’ appraisals of mobility technology reflect a nuanced appreciation of device costs; functional, social, and psychological benefits; and limitations. Results provide guidance to therapists and manufacturers regarding device use. - Implications for Rehabilitation
Potential users of robotic locomotor exoskeletons with spinal cord injuries appreciate the functional, social, and psychological benefits that these devices may offer. Their appraisals reflect nuanced consideration of device cost and features, and the suitability of the assistive technology to their circumstances. They recommend that manufacturers focus on reducing cost, extending battery life, and features that allow independent use. 相似文献

AbstractAim: Assistive technologies traditionally rely on either powered actuation or passive structures to provide increased strength, support or the ability to perform specific functions. At one end of the spectrum are powered exoskeletons, which significantly increase a user’s strength, but require powerful actuators, complex control systems and heavy power sources. At the other end are orthoses, which are generally unpowered and light in weight, relying on the mechanical properties of passive mechanical elements. Ideally, assistive technologies should combine the benefits of both systems and enhance human motion while remaining lightweight and efficient. This paper presents the development of a lightweight unpowered ankle exoskeleton that relies on the spring-like properties of a Pneumatic Artificial Muscle, which is inflated and sealed. Methods: This flexible air-spring is used to harness gait energy and compliment the human ankle torque at push-off. To mechanically validate the proposed exoskeleton design, a prototype was fabricated and experimentally tested. Results: Unlike other existing devices, the proposed unpowered exoskeleton was able to store a significant amount of energy and release it all at once. The timing mechanism worked as intended and triggered the release of 115?N?m of torque when the ankle reached a pre-determined angle. Conclusion: Overall, the device demonstrated the ability to provide significant contribution to the ankle torque, timed to release precisely at the push-off phase of the gait cycle. - Implications for Rehabilitation
The currently proposed ankle exoskeleton makes use of an unpowered, fully mechanical system to provide walking assistance to users by providing additional torque to the ankle joint. The newly developed assistive device is devised as a solution for persons struggling with mobility issues, and can be used both as a means for rehabilitation or as a permanent assistive devices for patients struggling with long-term disabilities. The device also has potential to be used as a performance enhancing device for ablebodied users by reducing muscle fatigue during extended physical exertion. 相似文献

AbstractPurpose: Ambulation is an important objective for people with pathological gaits. Exoskeleton robots can assist these people to complete their activities of daily living. There are exoskeletons that have been presented in literature to assist the elderly and other pathological gait users. This article presents a review of the degree of support required in the elderly and neurological gait disorders found in the human population. This will help to advance the design of robot-assisted devices based on the needs of the end users. Methods: The articles included in this review are collected from different databases including Science Direct, Springer Link, Web of Science, Medline and PubMed and with the purpose to investigate the gait parameters of elderly and neurological patients. Studies were included after considering the full texts and only those which focus on spatiotemporal, kinematic and kinetic gait parameters were selected as they are most relevant to the scope of this review. A systematic review and meta-analysis were conducted. Results: The meta-analysis report on the spatiotemporal, kinematic and kinetic gait parameters of elderly and neurological patients revealed a significant difference based on the type and level of impairment. Healthy elderly population showed deviations in the gait parameters due to age, however, significant difference is observed in the gait parameters of the neurological patients. Conclusion: A level of agreement was observed in most of the studies however the review also noticed some controversies among different studies in the same group. The review on the spatiotemporal, kinematics and kinetic gait parameters will provide a summary of the fundamental needs of the users for the future design and development of robotic assistive devices. 相似文献

Background and aim: Cognitive impairments following brain injury, including difficulty with problem solving, can pose significant barriers to successful community reintegration. Problem-solving strategy training is well-supported in the cognitive rehabilitation literature. However, limitations in insurance reimbursement have resulted in fewer services to train such skills to mastery and to support generalization of those skills into everyday environments. The purpose of this project was to develop and evaluate an integrated, web-based programme, ProSolv, which uses a small number of coaching sessions to support problem solving in everyday life following brain injury. Method: We used participatory action research to guide the iterative development, usability testing, and within-subject pilot testing of the ProSolv programme. The finalized programme was then evaluated in a between-subjects group study and a non-experimental single case study. Results: Results were mixed across studies. Participants demonstrated that it was feasible to learn and use the ProSolv programme for support in problem solving. They highly recommended the programme to others and singled out the importance of the coach. Limitations in app design were cited as a major reason for infrequent use of the app outside of coaching sessions. Conclusions: Results provide mixed evidence regarding the utility of web-based mobile apps, such as ProSolv to support problem solving following brain injury. - Implications for Rehabilitation
People with cognitive impairments following brain injury often struggle with problem solving in everyday contexts. Research supports problem solving skills training following brain injury. Assistive technology for cognition (smartphones, selected apps) offers a means of supporting problem solving for this population. This project demonstrated the feasibility of a web-based programme to address this need. 相似文献

Purpose: Technology holds great potential to support Deaf individuals as they age into older adulthood. However, it is unclear to what extent Deaf seniors are using technology in everyday life or whether they experience challenges in using technology. The current study explored technology use among older Deaf adults with regard to attitudes, adoption style, and frequency of use for a wide range of technologies, including assistive technologies (ATs) for persons with hearing loss and general, everyday technologies. Materials and methods: We developed a questionnaire that assessed older Deaf adults’ use of and experiences with technology. The questionnaire was made available in online and paper versions. Participants ( N?=?109) were recruited from national conferences and organizations for the Deaf. Results: Overall, we found that the older Deaf adults were technology adopters and regularly use and feel comfortable with a variety of devices. However, we also identified a number of technologies that are not being used by this population, including an AT that appears to have become obsolete and technologies that use sound-based alerts. Conclusions: Insights on how older Deaf adults are embracing technology and which devices they are actually using can help policy makers, technology developers, and a range of aging services professionals, better meet the needs of this understudied population. - Implications for Rehabilitation:
Older Deaf adults use a variety of assistive and everyday technologies and must be considered as consumers and included in the design process. Older Deaf adults are generally positive in their attitudes towards technologies but they are infrequent users of potentially beneficial health technologies, highlighting opportunities for future research and development. Assistive technology for the Deaf (TTY/TTD) appears to have become obsolete with advances in modern communication technologies, which has implications for policy decisions. 相似文献

AbstractPurpose: The advances in artificial intelligence have started to reach a level where autonomous systems are becoming increasingly popular as a way to aid people in their everyday life. Such intelligent systems may especially be beneficially for people struggling to complete common everyday tasks, such as individuals with movement-related disabilities. The focus of this paper is hence to review recent work in using computer vision for semi-autonomous control of assistive robotic manipulators (ARMs). Methods: Four databases were searched using a block search, yielding 257 papers which were reduced to 14 papers after applying various filtering criteria. Each paper was reviewed with focus on the hardware used, the autonomous behaviour achieved using computer vision and the scheme for semi-autonomous control of the system. Each of the reviewed systems were also sought characterized by grading their level of autonomy on a pre-defined scale. Conclusions: A re-occurring issue in the reviewed systems was the inability to handle arbitrary objects. This makes the systems unlikely to perform well outside a controlled environment, such as a lab. This issue could be addressed by having the systems recognize good grasping points or primitive shapes instead of specific pre-defined objects. Most of the reviewed systems did also use a rather simple strategy for the semi-autonomous control, where they switch either between full manual control or full automatic control. An alternative could be a control scheme relying on adaptive blending which could provide a more seamless experience for the user. - Implications for rehabilitation
Assistive robotic manipulators (ARMs) have the potential to empower individuals with disabilities by enabling them to complete common everyday tasks. This potential can be further enhanced by making the ARM semi-autonomous in order to actively aid the user. The scheme used for the semi-autonomous control of the ARM is crucial as it may be a hindrance if done incorrectly. Especially the ability to customize the semi-autonomous behaviour of the ARM is found to be important. Further research is needed to make the final move from the lab to the homes of the users. Most of the reviewed systems suffer from a rather fixed scheme for the semi-autonomous control and an inability to handle arbitrary objects. 相似文献

AbstractPurpose: In the context of assistive technology, mobility takes the meaning of “moving safely, gracefully, and comfortably”.The aim of this article is to provide a system which will be a convenient means of navigation for the Visually Impaired people, in the public transport system. Method: A blind regular commuter who travels by public transport facility finds difficulty in identifying the vehicle that is nearing the stop. Hence, a real-time system that dynamically identifies the nearing vehicle and informs the commuters is necessary. This paper proposes such a system namely the “Vehicle Board Recognition System” (VBRS). Computer Vision techniques such as segmentation, object recognition, text detection and optical character recognition are utilized to build the system, which will detect, analyze, derive and communicate the information to the passengers. Results: Thanks to the rapid development in technology, there are several navigation systems both hand held and wearable, available to help visually impaired (VI) people move comfortably both indoor and outdoor. Many blind people are not comfortable in using these devices or they are not affordable for them. Thus the proposed system gives them the comfort of navigation. Conclusion: This system can be installed in the bus stop to assist the Visually Impaired, from externally rather than their hand held or wearable assistive devices. - Implications for rehabilitation
This proposed system will help the visually impaired to ensure secure navigation be independent of the others develop self confidence. overcome the training, affordability of wearable/ handheld devices. 相似文献

AbstractObjectives: To determine the influence of a bootcamp training approach on students’ self-efficacy for assessing, training, spotting, documenting, and performing manual and power wheelchair skills. Methods: In a pre-post design, students in their final year of an entry-to-practice master of occupational therapy program completed a two-day manual (6.5?h) and power (6.5?h) wheelchair skills bootcamp. Outcomes for self-efficacy (in assessing, training, spotting and documenting manual and power wheelchair skills; primary) and capacity (manual and power wheelchair skills; secondary) were collected at baseline and immediately after the bootcamp. Results: Participants ( n?=?44) were 27.3?±?4.3?years of age (41 female). Most students (81.8%) reported little previous experience using manual and power wheelchairs at baseline. Students’ self-efficacy for assessing, training, spotting, and documenting manual and power wheelchair skills improved by between 28.4% and 35.3%, representing a change from ‘somewhat confident’ to ‘fairly confident’. Students’ manual and power wheelchair skills capacity increased by 47.2% and 37.1% respectively. Conclusions: Wheelchair skills training bootcamps may help prepare occupational therapy students to assess, train, spot, and document manual and power wheelchair skills of future clients, while improving students’ wheelchair skills capacity; thus may provide an option for integrating wheelchair skills training into the curriculum of time-intensive programs. - Implications for rehabiliation
A two-day condensed wheelchair skills training workshop improves occupational therapy students’ self-efficacy for assessing, training, spotting and documenting power and manual wheelchair skills. A two-day condensed wheelchair skills training workshop improves occupational therapy students’ power and manual wheelchair skills. Self-efficacy is an indicator of future behaviours. Therefore, improving students’ selfefficacy for assessing training and documenting wheelchair skills may influence their future practice. 相似文献

Purpose: This paper explores the barriers which people with disabilities experience in accessing health care services in Malawi. Methodology: Fifty-two in-depth interviews were conducted with people with various types of disabilities. These interviews were conducted in four districts in Malawi: Blantyre and Phalombe in the Southern Region; Ntchisi in the Central Region, and Rumphi in the North. A team of trained research assistants conducted the interviews. Results: The major challenges that people with disabilities experience include the cost of accessing health care, long distances to health facilities, lack of transport, hilly terrains and flooding of rivers during the rainy season, communication challenges with the health providers and poor attitude of health workers. Some of these challenges are not unique to people with disabilities, but constitute more of a problem among people with disabilities. Conclusion: There is a need to address these challenges through the expansion of the provision of assistive devices, implementing comprehensive outreach services targeting people with disabilities and strengthening the links between key component of access to quality health care. Attitudinal barriers and lack of resources remain major challenges. - Implications for rehabilitation
Though people with disabilities face challenges accessing health care world-wide, the challenges are greater in low-income countries. The current study in Malawi confirms this. Major challenges include costs of care, transport costs, and inaccessible facilities. Lack of health worker awareness and attitudinal barriers are major issues of concern. It is imperative, given this situation, that effort is spent in Malawi and similar contexts on dealing with issues of stigma and discrimination especially in the health care sector. It is also important to explore cost-effective ways of assisting people with disabilities accessing appropriate transport, which should be seen as part of the healthcare system. Though the cost of providing equitable care may be high in low-income contexts, this is a human right. Training and creating an accessible and disability-friendly service environment is a key priority. 相似文献

Purpose: Rehabilitation professionals have little information concerning lower limb exoskeletons for people with paraplegia. This study has four objectives: (1) Outline the characteristics of the exoskeletons’ design and their usefulness evidence as assistive mobility devices in the community for the Rewalk?, Mina, Indego®, Ekso? (previously known as the eLEGS?) and Rex®; (2) document functional mobility outcomes of using these exoskeletons; (3) document secondary skills and benefits achieved with these exoskeletons, safety, user satisfaction and applicability in the community; and (4) establish level of scientific evidence of the selected studies. Method: A systematic review of the literature (January 2004 to April 2014) was done using the databases PubMed, CINAHL and Embase and groups of keywords associated with “exoskeleton”, “lower limb” and “paraplegia”. Results: Seven articles were selected. Exoskeleton use is effective for walking in a laboratory but there are no training protocols to modify identified outcomes over the term usage (ReWalk?: 3 months, Mina: 2 months and Indego®: 1 session). Levels of evidence of selected papers are low. Conclusions: The applicability and effectiveness of lower limb exoskeletons as assistive devices in the community have not been demonstrated. More research is needed on walking performance with these exoskeletons compared to other mobility devices and other training contexts in the community. - Implications for rehabilitation
Characteristics of the exoskeletons’ design and their usefulness evidence as assistive mobility devices in the community are addressed for the Rewalk?, Mina, Indego®, Ekso? and Rex® ReWalk?, Indego® and Mina lower limb exoskeletons are effective for walking in a laboratory for individuals with complete lower-level SCI. The ReWalk? has the best results for walking, with a maximum speed of 0.51 m/s after 45 sessions lasting 60 to 120 min; it is comparable to the average speed per day or per week in a manual wheelchair. The level of scientific evidence is low. Other studies are needed to provide more information about performance over the longer term when walking with an exoskeleton, compared to wheelchair mobility, the user’s usual locomotion, the use of different exoskeletons or the training context in which the exoskeleton is used. 相似文献

AbstractAim: The aim of this review paper is to summarize recent developments and research in robotics, relevant to the field of ankle rehabilitation, to overview new findings and determine the actual state of the art. Method: The literature search was performed using scientific and medical databases (Scopus, PubMed and Web of Science) and other websites related to robots used in the area of ankle rehabilitation, analysing studies from 1950s to present. Information about the mechanical and kinematic specifications, actuation and stage of development was extracted from the selected literature. Results: Several types of rehabilitation robots have been considered, and they were classified depending on their architecture and design features. We we found that, regardless of the differences in architectures, only a few of them have been commercialized. The majority of rehabilitation robots designs allows plantarflexion-dorsiflexion movements. Unless some exceptions, most of the wearable robots do not allow the adduction-abduction movement. Neither the physical appearance of the robot nor the user’s perception towards it has not regularly been taken into account in the design stage. This limits the possibility of successful commercialization. Conclusions: Up to the present moment, the main challenges in the field of robot rehabilitation are the lack of unique rehabilitation protocols capable to fulfil the needs of all types of patients and the additional resources to measure the effectiveness of proposals that have not yet been commercialized. Nonetheless, we have mentioned above three areas were the challenges in design are more pressing. The first one is the robot architecture, which still presents some incommodities nowadays to emulate the ankle joint movement in a natural way. Thus, the displacements experienced by the axes in the joint must be adaptable to each patient and a wide range of pathologies. Moreover, many proposals are not been conceived to the purpose of commercialization, and even less to become an object of personal use. - Implications for rehabilitation
This review states that the use of robotic devices for ankle rehabilitation is a consolidated paradigm in the ankle’s rehabilitation. Platform-based robots allow to do complex and specialized spatial movements and these architectures endow the device with high stiffness, a balanced force distribution and better adaptability to the mechanical properties of human ankle joints. Unless some exceptions, most of the wearable robots do not allow the adduction-abduction movement. For a full integration of these technologies in the ankle’s rehabilitation field, more clinical evaluations are needed. Regardless of the potential of robotic devices in rehabilitation, only a few of them have been commercialized. 相似文献

AbstractBackground: Technology devices and applications including virtual reality (VR) are increasingly used in healthcare research and practice as tools to promote health and wellbeing. However, there is limited research examining the potential for VR to enable improved communication for people with communication disability. Aims: To review: (a) current research using VR in speech-language pathology; and (b) the ethical and safety considerations of VR research, to inform an agenda for future research applying VR in the field of speech-language pathology. Main contribution: This review reveals that there is an emergent body of literature applying VR to improve or develop physical, psychological and communication interventions. Use of non-immersive virtual environments to provide speech-language pathology assessment or intervention for people with communication disability has demonstrated positive outcomes, with emerging evidence of the transfer of functional communication skills from virtual to real-world environments. However, the use of VR technology and immersive virtual environments in communication disability practice and research introduces safety and ethical issues that must be carefully considered. Conclusions: Research employing VR is in its infancy in the field of speech-language pathology. Early evidence from other healthcare disciplines suggests that VR is an engaging means of delivering immersive and interactive training to build functional skills that can be generalized to the real world. While the introduction of new technology requires careful consideration of research ethics and patient safety, future VR communication research could proceed safely with adequate engagement of interdisciplinary teams and technology specialists. - Implications for rehabilitation
Immersive virtual reality may be used in rehabilitation to simulate natural environments to practice and develop communication skills. The sense of immersion that can be achieved using virtual reality may promote the generalization of skills learnt during clinical rehabilitation to real-world situations. Ethical and safety considerations, including cybersecurity and cybersickness, must be carefully monitored during all virtual reality research. 相似文献

AbstractPurpose: Upper limb prostheses are part of a rapidly changing market place. Despite development in device design, surveys report low levels of uptake and dissatisfaction with current prosthetic design. In this study, we present the results of a survey conducted with people with upper limb difference in Australia on their use of current prostheses and preferences in a prosthetic in order to inform future prosthetic hand design. Methods: An online survey was conducted on upper limb amputees, with 27 respondents that completed the survey. The survey was a mixture of open-ended questions, ranking design features and quantitative questions on problems experienced and desired attributes of future prosthesis designs. Results: Common key issues and concerns were isolated in the survey related to the weight, manipulation and dexterity, aesthetics, sensory feedback and financial cost; each of which could be addressed by additive manufacturing and soft robotics techniques. Conclusions: The adaptability of additive manufacturing and soft robotics to the highlighted concerns of participants shows that further research into these techniques is a feasible method to improve patient satisfaction and acceptance in prosthetic hands. - Implications for rehabilitation
Even with recent developments and advances in prosthetic design, the needs and desires of prosthetic users are not being met with current products. The desires and needs of those with upper limb difference are diverse. Using additive manufacturing to produce prosthetics allows for mass customization of prosthetics to meet these diverse needs while reducing costs. A soft robotic approach to prosthetics can help meet the desires of reducing weight and costs, while maintaining functionality. 相似文献

AbstractObjective: This study describes the first use of a robotic walker in youth and young adults with cerebral palsy (CP) Gross Motor Function Classification (GMFCS) IV. Methods: Semi-structured interviews were conducted before and after each robotic walker trial. Interviews were recorded, then transcribed and subjected to thematic analysis. Results: Five participants (4 male, 13–22?years of age) with quadriplegia secondary to CP were recruited. Four individuals with mixed tone quadriplegia GMFCS IV were able to independently walk with the device. One individual with significant dyskinesia was unable to utilize the device. The assessment team included two physiotherapists, an occupational therapist, a physiatrist and three engineers. Major themes related to physical and social impacts were identified. Some physical advantages include the ability to walk hands-free and promotion of physical fitness. Examples of physical barriers include limited harness design and large device size. Social advantages include increased independence and peer engagement. Finally, a social disadvantage identified was limited use on uneven terrains. Discussion: Suggestions for modifications for identified challenges and disadvantages include decreasing the size of the robotic walker, more harness designs, decreasing the force required to take an initial step, adding a joy stick for user control and creating a more versatile base that can be used on different terrains such as ice or baseball fields. Conclusion: Robotics holds great hope for individuals with CP where mobility options are limited. Physical and social advantages are evident. Recommendations for future improvement and studies of use in exercise and participation are provided. - IMPLICATIONS FOR REHABILITATION
As youth and young adults with cerebral palsy age, options for mobilization can become limited with challenges in placing them in a walking device due to size and numerous other physical limitations. A robotic walker with a built-in mechanical lift is available for individuals with cerebral palsy. This study was able to gather important information and recommendations to tailor a new robotic walker prototype specifically for individuals with cerebral palsy. 相似文献

AbstractPurpose: Children with cerebral palsy may face difficulties using handheld pointing devices, due to involuntary muscle movements. This study aimed at describing the idea of the new wearable sensor switch and assessing its feasibility as an access solution in a case of mixed-type cerebral palsy. Methods: The study participant was a 17-year-old male with mixed-type cerebral palsy characterized by chorea-athetotic movements and bilateral spasticity with gross motor function classification system level V. He exhibited sudden and irregular involuntary upper limb movements when sitting. Because spastic finger movements limited his ability to use a handheld mouse, he used a trackball near his neck as a pointing device (previous input method). The wearable switch system using a stretchable strain sensor was introduced; the sensor was attached to a groove worn on the dorsal regions of the right hand crossing the proximal interphalangeal and metacarpophalangeal joints of the middle finger (new input method). The switch turned on when the subject flexed his middle finger. Results: The user successfully turned the switch on and typed almost the same numbers of characters per trial compared with the previous input method. The speed of his head movements during typing reduced ( p?<?.01), and his sitting posture was nearly upright during computer operation ( p?<?.01). No involuntary movement, requiring physical assistance, was observed when using the wearable switch. Conclusion: The new switch system can be a new option for people with difficulty using standard handheld input devices due to paralysis and involuntary muscle movements. - Implications for rehabilitation
Cerebral palsy is a major cause of motor dysfunction and spasticity and dyskinesia in the fingers and upper limbs may prevent children with cerebral palsy from using handheld input devices. Wearable devices may be useful for children with cerebral palsy who have limited access to handheld pointing devices. We developed a new wearable switch to control devices using a flexible stretchable sensor. The wearable switch contributed to the improvement of sitting posture and reduction of neck burden during the typing task at the speed equivalent to that using the previous method in a child with mixed type of cerebral palsy exhibiting choreoathetotic movements and bilateral spasticity. 相似文献

AbstractPurpose: Memory impairment can necessitate use of external memory aids to preserve functional independence. As external aids can be difficult to learn and remember to use, technology may improve the efficacy of current rehabilitation strategies. We detail the iterative development of a digital application of a paper-and-pencil memory notebook. Methods: Twenty participants (aged 54+) of varying levels of cognitive ability were recruited for four iterations of usability testing (five participants per iteration). Each participant completed a series of tasks using the digital memory notebook (DMN), followed by questionnaires that assessed satisfaction (Questionnaire for User Interface Satisfaction) and usability ratings (Post-Study System Usability Questionnaire) for the application. Results and Conclusions: Between Iterations 2 and 5, participants demonstrated marked reductions in time to complete several types of tasks (e.g., add event, navigate interface) using the DMN. Participants in Iteration 5 also rated all subscales of both the usability and satisfaction questionnaires very highly. Faster task completion times were correlated with more favourable system ratings. However, neither task performance times nor system ratings were correlated with cognitive abilities, scheduling tool use or comfort with technology. Both the questionnaire and performance-based data indicate the final iteration of the DMN was easy to use. Furthermore, the application was user-friendly despite individual differences in cognitive ability, familiarity with scheduling tools and comfort with technology. Future work will demonstrate whether the DMN will support everyday retrospective and prospective memory lapses and increase the functional independence and quality of life for persons with cognitive impairment. - Implications for rehabilitation
Building on practice standards and user-centred design, the digital memory notebook (DMN) application is an “all-in-one” memory aid and organizational tool with an intuitive interface designed to help improve everyday functioning. The DMN’s today page, to do list and calendar functions can support everyday prospective and retrospective memory abilities. The DMN’s notes, journaling and motivational functions can support longer-term goal planning and mood management. The DMN’s alarm functions can support learning to use the DMN and serve as reminders to support prospective memory and aid in activity completion. 相似文献
