Design of EMG-driven Musculoskeletal Model for Volitional Control of a Robotic Ankle Prosthesis [PDF]

arXiv, 2022
Existing robotic lower-limb prostheses use autonomous control to address cyclic, locomotive tasks, but they are inadequate to operate the prosthesis for daily activities that are non-cyclic and unpredictable. To address this challenge, this study aims to design a novel electromyography (EMG)-driven musculoskeletal model for volitional control of a ...

Toward a Refined PI‐RADS: The Feasibility and Limitations of More Informative Metrics in Reviewing MRI Scans

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT The Prostate Imaging–Reporting and Data System (PI‐RADS) is a widely‐adopted framework for assessing prostate cancer risk using multiparametric MRI. However, as advancements in imaging and data analytics emerge, PI‐RADS faces pressure to integrate novel quantitative techniques, enhanced imaging protocols, and artificial intelligence (AI ...

Massive Femoral Osteolysis Secondary to Loosening of a Cemented Roughened Long Stem: A Case Report

Case Reports in Orthopedics, 2014
The surface finish of a femoral stem plays an important role in the longevity of cemented total hip arthroplasty. In efforts to decrease the rate of aseptic loosening, some prostheses have been designed to have a roughened surface that enhances bonding ...

The Influence of Cup Orientation on the Primary Fixation of a Hemispherical Cementless Acetabular Cup: A Cohort Based Finite Element Study

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Cup orientation has been investigated in detail with respect to risk of dislocation, however, the impact on the primary fixation of cementless cups is poorly understood. The aim of this study was to assess the influence acetabular component orientation on the primary fixation of cementless acetabular cups using an in silico clinical trial ...

The influence of push-off timing in a robotic ankle-foot prosthesis on the energetics and mechanics of walking [PDF]

, 2015
Background: Robotic ankle-foot prostheses that provide net positive push-off work can reduce the metabolic rate of walking for individuals with amputation, but benefits might be sensitive to push-off timing.

Anemia, Abnormal Body Mass Index, and Sarcopenia Increase Complication Risk in Patients Undergoing Surgical Treatment for Metastatic Bone Disease

Journal of Surgical Oncology, EarlyView.
ABSTRACT Background and Objectives Metastatic bone disease (MBD) is a common complication of primary cancers and is typically managed surgically. Overall health status and nutritional optimization are essential in surgical outcomes. The objective of this study was to report the intersectionality of previously studied laboratory, imaging, and clinical ...

Revision of reversed shoulder arthroplasty : is a reoperation possible? [PDF]

, 2017
Introduction. As the number of reversed shoulder arthroplasty (RSA) procedures increases, the revision rate will also increase. In case of severe bone insufficiency, instability or infection of the primary RSA, revision to another RSA is preferable but ...

Variability analysis of δ Scuti candidate stars [PDF]

, 2018
The Hipparcos catalog contains stars suspected to be {\delta} Scuti variables for which extensive ground-based observations and characterization of variability are necessary. Our aim was to characterize variability of 13 candidates to {\delta} Scuti type stars.

Improved quadriceps efficiency with a medial pivot in comparison to a cruciate‐retaining design in total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The posterior cruciate‐retaining (CR) design offers rotational freedom but risks abnormal kinematics and instability. The medial pivot (MP) design mimics native joint motion with a high‐conformity medial and flat lateral interface. Within clinical studies, the MP design outclassed the CR design, but biomechanical studies are lacking ...
