Simultaneous Multi-Joint Myoelectric Control of Transradial Prostheses
… and hand opening-closing) of a transradial prosthesis to be controlled in a highly coordinated fashion. We demonstrated than a time-delayed artificial neural network controller could be trained to accurately predict motions of several key hand and wrist motions using myoelectric …

Modeling Upper Body Kinematics While Using a Transradial Prosthesis
… range of motion. Relative to anatomical joints transradial (below the elbow) prosthesis users lose at least two of the three degrees of freedom provided by the wrist and forearm. Some myoeletric prostheses currently allow for forearm pronation and supination (rotation about an axis parallel to …

The Study of Compensatory Motions While Using a Transradial Prosthesis
… requires knowledge of how the body adapts. A transradial prosthesis without a dynamic wrist component may cause awkward compensatory motion leading to fatigue, injury or rejection of the prosthesis. This work analyzed the movements of shoulder, elbow and torso during four tasks: drinking from …

Design and Development of an Open-Source ADL-Compliant Prosthetic Arm for Transradial Amputees
Transradial amputation is traumatic – leading to the amputee having a limited ability to perform activities of daily living (ADLs). Below-elbow prostheses are prescribed. The high cost associated with prostheses results in many amputees in low-to-middleincome countries relying on government …

Design and development of a sensory feedback system for transradial amputees using body powered prostheses
… the design can be revalidated and tested on transradial amputees. Future work includes performing usability studies with amputee subjects, revalidation of the design through bench testing and with amputee subjects, and evaluating the scalability and manufacturability of the design with a …

Kinematic analysis of compensation movements of upper limb amputees and able-bodied individuals during grasping movements
… the next distal joint nearby the amputation. For transradial prosthesis users, the main compensatory movements often occur because of limited degrees of freedom and lack of control in the prosthetic wrist. Compensatory movements have been associated with musculoskeletal complaints (MSC), overuse …

Impact of Transradial Approach in Patients with High Risk Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention and Abciximab on In-Hospital Clinical Outcomes and Bleeding Complications
… increasing numbers of studies suggesting that transradial coronary intervention (TRI) is associated with better clinical outcomes by reducing bleeding and vascular complications when compared with transfemoral coronary intervention (TFI). The benefit of TRI might be enlarged in patients at high …

Giving birth to a new approach: a retrospective comparison of radiation safety parameters between transradial and transfemoral approaches for uterine fibroid embolization at Groote Schuur Hospital, South Africa
… of South African interventional radiologists. Transradial access (TRA) has grown as a viable alternate vascular access. The advantages of TRA over TFA have been well documented, however a lack of safety parameter comparison in procedures performed via TRA versus TFA remains. Objectives: To …

Development of a low-cost high-impact resistant compliant myoelectric prosthetic hand
… capabilites of our hand with a subject with a transradial amputation. We show that using contact reflexes and sensory substitution, when compared to standard myoelectric prostheses that lack these features, improves grasping of delicate objects like an eggshell and a cup of water both with and …

Promoting enhanced motor planning in prosthesis users via matched limb imitation
… system (FAMS) to simulate the limb movement that transradial amputees experience. Matched limb imitation in FAMS users yielded better movement technique compared to mismatched imitation. Finally, the longitudinal effects of a matched limb training paradigm on the cortical action encoding activity …
