The burden on these caregivers is exacerbated by steadily increasing obesity rates, which are highest in adults aged 50 to 70. The Caregiver-Assist Transport Chair (CATC) is designed to address the difficulty many caregivers experience assisting in the transportation of moderate to low mobility care recipients outside of the home for appointments, community engagements, or fresh air excursions. It is not uncommon for the caregiver to be elderly or of a smaller build than the care recipient, increasing the difficulty of pushing a transport chair for extended distances or across uneven or unlevel terrain. The CATC is equipped with intelligent motorized wheels that engage in the forward or reverse directions to maintain a consistently low effort required from the caregiver, independent of the weight of the care recipient. The chair assists on uphill terrain and slows on downhill descents to match the walking speed of the caregiver. In addition, the chair has a drop-down footplate mechanism that eliminates the need for the legs of the care recipient to be lifted onto foot pedals once seated. This footplate also serves as a brake to eliminate safety concerns associated with the chair rolling back as the user transitions between sitting and standing. While the CATC contains motorized elements, unlike a typical motorized wheelchair, it is lightweight, foldable, and easy to maneuver in and out of a vehicle.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132422375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, there is a lack of clear understanding of attributes associated with deep and superficial muscles when it is intended to study the recovery progress after rehabilitation. Through a systematic approach, this project investigates the activation of rotator cuff muscles using surface electromyography (sEMG) sensors. The team developed a strategic plan to investigate the precision of the NORAXON technology that is utilized in this study to ensure that it is capable of capturing small variations in shoulder motion. This is followed by a reliability analysis to ascertain reproducibility of the experiment. The levels of muscle activities for superficial and deep muscles are monitored to explore the impact of traditionally prescribed arm movements used for the rehabilitation of rotator cuff injuries. Furthermore, an analysis of forces generated in the muscles is done to provide better insight into the activation levels of rotator cuff muscles. The results were promising, with a competent technology and acceptable correlation associated with muscle activities across all subjects. Four common arm movements were studied; scaption generated a significant response in the targeted muscles, particularly of the supraspinatus. Results were conclusive across all subjects, and simulation also supported the experiment showing high activation levels for the supraspinatus. The teres minor also showed a significant contribution when performing external rotation at 90⁰ abduction. The outcome of this study is significant for this ongoing project as it identifies the most impactful exercises that ensure targeted muscles are being triggered. It also lays the groundwork for expanding the project to a clinical study focusing on the most effective arm movements in order to improve rehabilitation process and reduce pertinent cost.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"209 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133557054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solutions to address pressure sore prevention are limited. This work is aimed at developing devices to prevent pressure sores in wheelchair users with limited mobility or sensation. Informed by stakeholder input, we present a dynamic cushion design to sense areas of high pressure and actuate to relieve that pressure. We experimented using resistive sensors in a grid formation to map pressure across the seat. To relieve pressure, we propose a grid of custom pneumatic bladders to inflate in response to sensor thresholds. Bladders will inflate to redistribute pressure. After experimenting with a variety of possible bladder geometries, we selected torus-shaped actuators to optimize durability, stability, and increase breathability in the final design. Given the ability to fabricate custom bladders and program controls, the proposed device can be tailored to users’ specific needs. While static cushion solutions exist on the market, our custom design allows users to dynamically alleviate pressure eliminated the need to constantly readjust position and ultimately reduce time spent treating sores.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132878404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A variety of avenues have been explored, including priority patient routing, tele-health, neural networks for improving ER efficiency, predicting no-shows, consultation duration variations, and optimizing operating room utilization. Addressing this issue, a study was conducted using 700 pre-visit notes of pancreatic patients to determine the requirement of endoscopic or biliary procedure. Through natural language processing and traditional or transfer learning algorithms, data could directly be sent to EPIC for nurses to assess in further decision making. Performance of the models was above average with the transfer learning method outperforming the traditional method.

As a result, our team sought to develop a way to increase flexion and passive motion in the hand of a patient with titinopathy in order to gain functionality. This paper outlines the design and development of a novel therapeutic glove for a 4 year old boy with a neuromuscular disease that prevents him from flexing the two distal joints of his fingers.\u0000 The team has developed a low-cost hand movement glove (HMG) to be used as a supplement to traditional physical therapy. The device utilizes a motor-cable system secured to each finger, allowing for independent and synchronized flexion of each finger. Phase I of prototyping resulted in a working model to assess the finger movement mechanism and overall wearability of the device. Phase II utilized an Arduino Uno microcontroller, circuit switch, PCA9685 driver board, micro servo motors, a cotton woven glove, and 3-D printed components to characterize a more robust model allowing independent flexion of each finger.\u0000 Initial testing has proven the device’s ability to achieve physiologically relevant degrees of flexion in each finger. Upon completion of further testing, we anticipate this device having a profound impact as an additional tool utilized in the patient’s physical therapy regimen to allow for regained flexion at both proximal and distal interphalangeal joints.","PeriodicalId":325836,"journal":{"name":"2023 Design of Medical Devices Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126101635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
