Summary: The research developed a system that allows lower-limb prosthesis users to quickly release and relock the socket while sitting, addressing the challenges of residual limb volume fluctuation. Users preferred a specific tether length during partial doffing, with the system being easy to operate and capable of releasing and relocking in a short time.

Summary: Limited progress has been made in modernising the way upper-limb prosthetic sockets are made, with current techniques still heavily reliant on outdated casting methods and manual labor. While digital methods such as 3D scanning and printing hold promise for improving efficiency and patient satisfaction, challenges exist in implementing them in clinical settings. There is a disconnect between technology developers and the actual needs of clinicians and patients, highlighting the need for expert knowledge to guide the use of digital tools in prosthetic socket manufacturing.

Summary: The purpose of this research was to investigate the effects of an innovative cyclic panel-pull strategy on minimizing limb fluid volume loss in transtibial prosthesis users during ambulation. Results showed that adding panel-pull resulted in increased fluid volume for some participants, while uncoupling the liner from the panels and executing panel-pull led to decreased fluid volume for some participants. Panel-pull may be beneficial for retaining limb fluid volume in transtibial prosthesis users.

Summary: People with lower extremity amputation often face challenges in managing the fit of their prosthetic socket due to changes in fluid volume. This study found that intermittently doffing the prosthetic socket for as short as 4 minutes can help stabilize limb fluid volume. Further trials in real-life settings should be conducted.

Summary: This study proposes a self-powered triboelectric nanogenerator (TENG) based flexible tactile sensor array system for real-time monitoring of pressure distribution inside a prosthetic socket. The sensor is made of biocompatible PDMS polymer and PCL nanofiber membranes as triboelectric materials, providing high stability and low cost. Integration of the sensor array within a prosthetic device enables real-time monitoring of pressure distribution during gait simulation.

Summary: This in vitro study evaluated the influence of restoration design and manufacturing technique on the marginal discrepancy and internal fit of zirconia fixed dental prostheses. The results showed that the restoration design and veneering methods did not affect the marginal discrepancy, but did have an impact on the internal fit. Therefore, using monolithic zirconia fixed dental prostheses could be a viable alternative technique.

Summary: The use of CAD/CAM systems in the production of transtibial prosthetic sockets has gained global attention, but its application in developing countries is still limited. The main reasons include lack of resources, accessibility, knowledge gap, and insufficient experienced professionals. More large-scale trials are needed to promote the use of CAD/CAM in developing regions.

Summary: This study compared the accuracy and clinical relevance of different manufacturing methods for occlusal devices. It found that injection molding and subtractive manufacturing techniques showed the highest manufacturing accuracy and similar retention force, while additive manufacturing techniques had higher deviations but were still clinically acceptable.

Summary: This study demonstrates that by creating electro-neuromuscular constructs using distributed nerve transfers and implanted electrodes, the control capability of limb prostheses can be enhanced. The results show that this method allows for gradual increase in myoelectric signal strength, enabling individuals with above-elbow amputations to control wrist and finger prosthetic joints flexibly. This study is of great significance for improving the functionality of limb prostheses.

Summary: The purpose of this study was to investigate the dimensional stability of 3D-printed occlusal devices under different storage conditions. The results showed that the occlusal devices in the DL group had the least dimensional change at delta t(1), while no significant differences were found among the groups at delta t(2) and delta t(3). There were also no significant differences among the different locations after 27 days.
