A Current Conveyor Implementation of Double Differential Amplifier for Active Electrodes

International Journal of Circuit Theory and Applications, EarlyView.
A CCII‐based electronic architecture for surface electromyography (sEMG) signal acquisition is presented. Simulations results demonstrate its potential as an effective analog front‐end for biomedical monitoring applications. ABSTRACT This work presents two transistor‐level solutions to implement a double differential (DD) amplifier by using a current ...

Upper extremity surface electromyography signal changes after laparoscopic training [PDF]

, 2018
Introduction: Objective measures of laparoscopic skill in training are lacking. Aim: To evaluate the changes in the surface electromyography (sEMG) signal during laparoscopic training, and to link them to intracorporeal knot tying.

Nutrition and rehabilitation after anterior cruciate ligament reconstruction: A systematic review

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose As the impact of nutrition on rehabilitation and return to sport (RTS) after ACL reconstruction (ACLR) remains largely unexplored, this review aimed to review the current evidence on the role of nutrition in rehabilitation outcomes for ACLR patients, with as ultimate goal a safer and more successful RTS.

Exteroceptive Reflexes in Stiff Person Syndrome, Other Neurological Conditions and Healthy Controls

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Stiff person syndrome (SPS) is a rare disabling neurological condition with overlapping symptomatology with more common neurological conditions. Exaggerated exteroceptive reflex mechanisms are thought to play a role in its pathophysiology.

Electrical Modalities in the Rehabilitation of Peripheral Nerve Injuries: State of the Literature and Current Clinical Applications

Muscle &Nerve, EarlyView.
ABSTRACT Peripheral nerve injuries (PNIs) are a common cause of long‐term motor and sensory disability despite advances in microsurgical repair. Functional recovery following PNI depends not only on axonal regeneration, but also on preservation of distal nerve pathways, maintenance of neuromuscular junction integrity, prevention of irreversible muscle ...

Robust Bio-Signal Based Control of an Intelligent Wheelchair

Robotics, 2013
In this paper, an adaptive human-machine interaction (HMI) method that is based on surface electromyography (sEMG) signals is proposed for the hands-free control of an intelligent wheelchair. sEMG signals generated by the facial movements are obtained by
