Enhancing the Performance of a Biomimetic Robotic Elbow-and-Forearm System Through Bionics-Inspired Optimization [PDF]

arXiv, 2023
This paper delineates the formulation and verification of an innovative robotic forearm and elbow design, mirroring the intricate biomechanics of human skeletal and ligament systems. Conventional robotic models often undervalue the substantial function of soft tissues, leading to a compromise between compactness, safety, stability, and range of motion.

Positive, complicated, distant, and negative: How different teacher‐student relationship profiles relate to students’ science motivation

Journal of Adolescence, Volume 94, Issue 8, Page 1150-1162, December 2022., 2022
Abstract Introduction Researchers note a consistent decline in adolescents’ motivation and participation in science. It is important to examine factors vital to students’ motivation in science, such as teacher‐student relationships (TSRs). Limited research in science has examined TSRs from a multidimensional or person‐centered perspective.

Human elbow motor learning skills of varying loads: Proof of internal model generation using joint stiffness estimation

Journal of Biomechanical Science and Engineering, 2021
This study presents a human elbow motor learning strategy responding to varying loads. Inspired by Kawato’s internal model theory, we suggest hypothesis that human minimize the internal model error by updating the joint stiffness to generate stable and ...

A Fabric-based Pneumatic Actuator for the Infant Elbow: Design and Comparative Kinematic Analysis [PDF]

arXiv, 2023
This paper focuses on the design and systematic evaluation of fabric-based, bellow-type soft pneumatic actuators to assist with flexion and extension of the elbow, intended for use in infant wearable devices. Initially, the performance of a range of actuator variants was explored via simulation.

Development of the human elbow joint [PDF]

The Anatomical Record, 2000
Many studies have been published on the development of the human elbow joint, but authors disagree on its morphogenetic timetable. Most discrepancies center on the cavitation of the elbow joint (including the humeroradial, humeroulnar, and superior radioulnar joints), and the organization of the tunnel of the ulnar nerve.

Is there benefit to concurrent x‐ray imaging of the wrist, forearm and elbow in paediatric patients following a fall on the outstretched hand?

Journal of Medical Radiation Sciences, Volume 69, Issue 4, Page 431-438, December 2022., 2022
There is a limited benefit (1.7%), of concurrent imaging of the wrist, elbow and forearm in paediatric patients following a FOOSH where there is no clinical indication for imaging outside of the region of interest. Results support previous findings that a thorough clinical assessment of the wrist, forearm and elbow is sufficient to guide X‐ray imaging.
