Purpose: To gain an understanding of the embodied perceptual experience of successful prosthesis.
Method: The data for this study were transcripts derived from in-depth semi-structured e-mail (n=21) and face-to-face (n=14) interviews, and the documentary analysis of an e-mail discussion group for prosthesis users. This qualitative data was subject to an Interpretative Phenomenological Analysis.
Results: Analysis of the research data identified six themes in the perceptually embodied experiences of prosthesis users: Adjusting to a prosthetic; The Balance of the Body; Awareness of the Prosthesis; The Knowing Body; The Phantom Becomes the Prosthesis: Extending the Body; and The Prosthesis as Tool or Corporeal Structure.
Conclusion: The often-cited reasons for the rejection of prostheses are frequently part of the initial experiences of 'successful' prosthesis users also. This suggests the need to sufficiently motivate potential prosthesis users in the period between an experience of prosthesis use as unnatural and wieldy to one of pre-reflective, natural use. In addition, two broad forms of prosthesis experience were identified: one in which the prosthesis was experienced as a corporeal structure; and one in which it was viewed as a tool. While future work may be able to explore the psychosocial correlates of these experiences, it is nonetheless the case that persons with these differing experiences were able to enjoy the benefits imbued by prosthesis use.

Objective: This study focuses on how patients experience the time following amputation after primary limb salvage surgery due to musculoskeletal malignancies. Limb salvage is state of the art in the treatment of musculoskeletal tumours. Nonetheless, in some cases, limb salvage can become problematic over time, resulting in poorer limb function and septic outcomes.

The human wrist affects the ability to efficiently perform many manipulation tasks. Despite this, most upper-limb prostheses are focused on the hand's mobility, which makes users compensate for the lost wrist mobility with complex manipulation strategies relying on the mobility of other body parts. In this context, research on wrist prostheses is still open to new contributions, even though a number of such prostheses are already present in the literature and on the market.

Purpose: This large-scale retrospective study aimed to examine the long-term effect of antiplatelet and anticoagulant medications intake on dental implant treatment outcome.
Materials And Methods: This study retrospectively examined data from patients who underwent dental implant procedures at several university dental clinics within the BigMouth network between 2011 and 2022. Patients' characteristics including age, gender, ethnicity, race, tobacco use, systemic medical conditions and intake of antiplatelets and anticoagulants were analyzed.

A human hand has 23-degree-of-freedom (DOF) dexterity for managing activities of daily living (ADLs). Current prosthetic hands, primarily driven by motors or pneumatic actuators, fall short in replicating human-level functions, primarily due to limited DOF. Here, we develop a lightweight prosthetic hand that possesses biomimetic 19-DOF dexterity by integrating 38 shape-memory alloy (SMA) actuators to precisely control five fingers and the wrist.

Background: The alignment of a bone-anchored prosthesis has consequences for the external moments around the residual joints and implant, and these external moments can lead to serious negative long-term effects. A clear understanding of the relationship between transtibial prosthetic alignment and external joint and implant moment for bone-anchored prosthetic users is still lacking.
Research Question: What is the effect of systematic frontal plane prosthetic alignment changes on lower limb external joint moments in people with a transtibial bone-anchored prosthesis?
Methods: Participants underwent gait analysis on an instrumented dual belt treadmill.
