Abstract
Existing prosthetic technologies for people with upper limb amputation are being adopted at moderate rates. Once fitted for these devices, many upper limb amputees report not using them regularly or at all. The primary aim of this study was to solicit feedback about prosthetic technology and important device design criteria from amputees, clinicians, and device regulators. We compare these perspectives to identify common or divergent priorities. Twenty-one adults with upper limb loss, 35 clinicians, and 3 regulators completed a survey on existing prosthetic technologies and a conceptual sensorimotor prosthesis driven by implanted myoelectric electrodes with sensory feedback via spinal root stimulation. The survey included questions from the Trinity Amputation and Prosthesis Experience Scale, the Disabilities of the Arm, Shoulder, and Hand, and novel questions about technology acceptance and neuroprosthetic design. User and clinician ratings of satisfaction with existing devices were similar. Amputees were most accepting of the proposed sensorimotor prosthesis (75.5% vs clinicians(68.8%), regulators(67.8%)). Stakeholders valued user-centered outcomes like individualized task goals, improved quality of life, device reliability, and user safety; regulators emphasized these last two. The results of this study provide insight into amputee, clinician, and regulator priorities to inform future upper-limb prosthetic design and clinical trial protocol development.

Use of Accessible Weight Scales and Examination Tables/Chairs for Patients with Significant Mobility Limitations by Physicians Nationwide. Jt Comm J Qual Patient Saf 2021; 47:615-626. [PMID: 34364797 PMCID: PMC8464497 DOI: 10.1016/j.jcjq.2021.06.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Revised: 06/14/2021] [Accepted: 06/15/2021] [Indexed: 11/17/2022]
Abstract
BACKGROUND Mobility limitations are the most common disability type among the 61 million Americans with disability. Studies of patients with mobility limitations suggest that inaccessible medical diagnostic equipment poses significant barriers to care. METHODS The study team surveyed randomly selected US physicians nationwide representing seven specialties about their reported use of accessible weight scales and exam tables/chairs when caring for patients with mobility limitations. A descriptive analysis of responses was performed, and multivariable logistic regression was used to examine associations between accessible equipment and participants' characteristics. RESULTS The 714 participants (survey response rate = 61.0%) were primarily male, White, and urban, and had practiced for 20 or more years. Among those reporting routinely recording patients' weights (n = 399), only 22.6% (standard error [SE] = 2.2) reported always or usually using accessible weight scales for patients with significant mobility limitations. To determine weights of patients with mobility limitations, 8.1% always, 24.3% usually, and 40.0% sometimes asked patients. Physicians practicing ≥ 20 years were much less likely than other physicians to use accessible weight scales: odds ratio (OR) = 0.51 (95% confidence interval [CI] = 0.26-0.99). Among participants seeing patients with significant mobility limitations (n = 584), only 40.3% (SE = 2.2) always or usually used accessible exam tables or chairs. Specialists were much more likely than primary care physicians to use accessible exam tables/chairs: OR = 1.96 (95% CI = 1.29-2.99). CONCLUSION More than 30 years after enactment of the Americans with Disabilities Act, most physicians surveyed do not use accessible equipment for routine care of patients with chronic significant mobility limitations.

Abstract
Clinicians and staff of the Department of Veterans Affairs Health Care System (VA), who provide services to veterans, have invented many devices and methods for improving veterans' lives. However, translating those inventions to the market has been a challenge due to limited collaboration between the clinical inventors and the scientists, researchers, and engineers who can produce the prototypes necessary for licensing the technology. The VA Technology Transfer Program office and the Human Engineering Research Laboratories, a research laboratory with experience with developing prototypes and licensing technology, jointly developed a program called the Technology Transfer Assistance Project (TTAP) to bridge the gap between clinical inventors and prototypes ready for licensing. This paper describes TTAP and provides examples of the first inventions that were developed or enhanced through TTAP.

Abstract
Pressure injuries are costly to the healthcare system and mostly preventable, yet incidence rates remain high. Recommendations for improved care and prevention of pressure injuries from the Joint Commission revolve around continuous monitoring of prevention protocols and prompts for the care team. The E-scale is a bed weight monitoring system with load cells placed under the legs of a bed. This study investigated the feasibility of the E-scale system for detecting and classifying movements in bed which are relevant for pressure injury risk assessment using a threshold-based detection algorithm and a K-nearest neighbor classification approach. The E-scale was able to detect and classify four types of movements (rolls, turns in place, extremity movements and assisted turns) with >94% accuracy. This analysis showed that the E-scale could be used to monitor movements in bed, which could be used to prompt the care team when interventions are needed and support research investigating the effectiveness of care plans.

Abstract
Objective: The overall objective of this project was to identify consumers' opinions of their needs and wants related to assistive technology (AT) in a systematic and quantitative manner via a questionnaire that can be used to validate existing and establish new research priorities. Methods: This pilot study describes questionnaire development, online implementation, and revisions considered to the questionnaire in preparation for conducting a nationwide survey. Data from a sample (N = 112) are presented. The pilot study was critical to refine the questions and ensure that meaningful information was being collected. Results: It was identified that revisions were warranted to provide more structure and allow for consumers to prioritize AT research efforts. Conclusion: The questionnaire results, although positively in favor of many of the technologies presented, are inconclusive to identify generalizable research priorities, thus expansion to a nationwide population is warranted.
