A prototype sensorized rocking chair was developed and confirmed as an activity that activates trunk muscles. This study uses data collected from the chair to predict muscle use during rocking. Methods: The prototype rocking chair included sensors to detect forces, accelerations, as well child and chair movement. Children with spinal cord injury and typically developing children (2-12 years), recruited under an approved IRB protocol, were observed rocking while sensor and electromyography data were collected from arm, leg, and trunk muscles. Features from sensor data were used to predict muscle activation using multiple linear regression, regression learning, and neural network modeling. Correlation analysis examined individual sensor contributions to predictions. Results: Neural network models outperformed regression models. Multiple linear regression predictions significantly correlated (p < 0.05) with targets for four of eleven children with SCI, while decision tree regression predictions correlated for five children. Neural network predictions correlated for all children. Conclusions: Embedded sensors capture useful information about muscle activation, and machine learning techniques can be used to inform therapists. Further work is warranted to refine prediction models and to investigate how well results can be generalized.","PeriodicalId":43319,"journal":{"name":"Journal of Rehabilitation and Assistive Technologies Engineering","volume":"11 ","pages":"20556683241278306"},"PeriodicalIF":2.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11363032/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142113176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Technology may be useful for delivering augmented feedback. Co-design methodology for developing therapeutic interventions has become popular in healthcare, including for technology in rehabilitation. However, there are limited guidelines on how to use co-design methodology in healthcare. Methods: We applied three key principles, (1) Understanding, (2) Exploring, and (3) Materialising, to inform a co-design process. End-user participants included paediatric clinicians, young learners, their caregivers, and the research team, who shared their expertise and lived experience to inform the creation of a novel system. Results: A team of end-users designed and developed an augmented reality intervention prototype for practicing motor skills aimed at children with DCD using a generative co-design process. From understanding the unmet needs, we explored and then materialised a series of games using bespoke technology solutions. Conclusion: The use of a co-design process was beneficial in engaging end-users as the experts of their experience in the creation of a novel augmented reality intervention prototype aimed for children with DCD. The co-design process was successful in facilitating a prototype that meets consumer needs, and ensured all end-user voices were heard.","PeriodicalId":43319,"journal":{"name":"Journal of Rehabilitation and Assistive Technologies Engineering","volume":"11 ","pages":"20556683241266780"},"PeriodicalIF":2.0,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11311161/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141917622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Descriptive statistics were used to examine utilization trends.Results: Survey responses from 1036 LLO users were analyzed.

Among participants with the four most prevalent health conditions, LLO use in the community was greatest among participants with Charcot-Marie-Tooth disease.Conclusions: LLOs were frequently used for a wide range of community-based activities. Simultaneous use of ADs and LLOs may be most beneficial for LLO users when performing activities outside of the home.

With advancements in remote monitoring and Artificial Intelligence, automatic tele-rehabilitation systems that can measure joint angles, recognize exercises, and provide feedback based on movement analysis are being developed. Such platforms can offer valuable information to clinicians for improved care planning. However, with various methods and sensors being used, understanding their pros, cons, and performance is important. This paper reviews and compares the performance of recent vision-based, wearable, and pressure-sensing technologies used in lower limb tele-rehabilitation systems over the past 10 years (from 2014 to 2023). We selected studies that were published in English and focused on joint angle estimation, activity recognition, and exercise assessment. Vision-based approaches were the most common, accounting for 42% of studies. Wearable technology followed at approximately 37%, and pressure-sensing technology appeared in 21% of studies. Identified gaps include a lack of uniformity in reported performance metrics and evaluation methods, a need for cross-subject validation, inadequate testing with patients and older adults, restricted sets of exercises evaluated, and a scarcity of comprehensive datasets on lower limb exercises, especially those involving movements while lying down.","PeriodicalId":43319,"journal":{"name":"Journal of Rehabilitation and Assistive Technologies Engineering","volume":"11 ","pages":"20556683241259256"},"PeriodicalIF":2.0,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11151759/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141262982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Maximum standing time was 30 min, less when symptoms of syncope or volitional exhaustion occurred. Besides total standing time, electromyography of thigh muscles, and changes in mean arterial pressure and heart rate were monitored at rest and during standing.Results: No significant differences were found in standing time, changes in mean arterial pressure or heart rate between standing in Innowalk Pro and the standing frame.

However, there are no powered solutions available for hip-level amputees, and most existing hip prostheses are mounted to the front of the prosthetic socket, thereby limiting range of motion. This research introduces a novel laterally mounted powered hip joint (LMPHJ) that augments user movement. The LMPHJ is mounted on the lateral side of the prosthetic socket, positioning the hip joint closer to the anatomical center of rotation while ensuring user safety and stability. The motor and electronics are located in the thigh area, maintaining a low profile while transmitting the required hip moment to the mechanical joint center of rotation. A prototype was designed and manufactured, and static testing was complete by modifying the loading conditions defined in the ISO 15032:2000 standard to failure test levels for a 100 kg person, demonstrating the joint's ability to withstand everyday loading conditions. Functional testing was conducted using a prosthesis simulator that enabled able-bodied participants to successfully walk with the powered prosthesis on level ground. This validates the mechanical design for walking and indicates the LMPHJ is ready for evaluation in the next phase with hip disarticulation amputee participants.","PeriodicalId":43319,"journal":{"name":"Journal of Rehabilitation and Assistive Technologies Engineering","volume":"11 ","pages":"20556683241248584"},"PeriodicalIF":2.0,"publicationDate":"2024-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11062215/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140872710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
