Feedback device of temperature sensation for a myoelectric prosthetic hand

Functional benefit of an adaptive myoelectric prosthetic hand compared to a conventional myoelectric hand.

Eight patients with a traumatic unilateral upper limb amputation, who used conventional myoelectric prostheses, were also fitted with a commercially available myoelectric prosthetic hand with an adaptive grip, in order to compare the functional benefit of the two types of prostheses. Comparisons were made regarding width of grip, force of grip, scores in a standardised grip function test and pr...

Design of a Myoelectric Controller for a Multi-dof Prosthetic Hand Based on Principal Component Analysis

The goal of this investigation is to develop a multidegree of freedom (DOF) prosthesis controller that uses myoelectric signals as control inputs and which has been dimensionally optimized using Principal Component Analysis (PCA). Currently available multi-DOF hand prostheses cannot be fully utilized because there are fewer control inputs than the number of degrees of freedom (i.e. – joints) th...

A Myoelectric Prosthetic Training System

Development of a Myoelectric Discrimination System for a Multi-Degree Prosthetic Hand

A multiple degrees of freedom prosthetic hand, NTU Hand, was developed in our laboratory. This paper is focused on the development of a myoelectric discrimination system for a multi-degree prosthetic hand. The discrimination system uses two surface electrodes to acquire the electromyography (EMG) signal from the flexor digitorum superficialis muscle and the extensor pollicis brevis muscle. Sinc...

Electro-tactile Feedback System for a Prosthetic Hand

Without the sense of touch, amputees with prosthetic hands can have difficulty holding and manipulating objects, especially when a task requires some degree of skill and tactile feedback to perform. To equip prosthetic hand users with touch sensing and tactile feedback, researchers have been experimenting with various types of force and/or tactile sensors together with various methods for deliv...
