Performances of one-dimensional sonomyography and surface electromyography in tracking guided patterns of wrist extension.
Electromyography (EMG) and ultrasonography have been widely used for skeletal muscle assessment. Recently, it has been demonstrated that the muscle thickness change collected by ultrasound during contraction, namely sonomyography (SMG), can also be used for assessment of muscles and has the potential for prosthetic control. In this study, the performances of one-dimensional sonomyography (1D SM...
متن کاملFeasibility of controlling prosthetic hand using sonomyography signal in real time: preliminary study.
The morphological changes of muscle can be accurately detected by sonography, a process we have termed sonomyography (SMG). This article investigates the feasibility of using muscle thickness deformation SMG as a new signal source to control a prosthetic hand in real time. Thickness deformation SMG of the extensor muscle was measured by a block-matching algorithm during wrist extension-flexion;...
متن کاملDynamic monitoring of forearm muscles using one-dimensional sonomyography system.
We introduce a method, known as one-dimensional sonomyography (1-D SMG), that uses A-mode ultrasound signals to detect dynamic thickness changes in skeletal muscle during contraction. We custom-designed a 1-D SMG system to collect synchronized A-mode ultrasound, joint angle, and surface electromyography (EMG) signals of forearm muscles during wrist extension. We extracted the 1-D SMG signal fro...
متن کاملJRRD At A Glance for Volume 47, Number 2, 2010
In this study, the thickness deformation of the forearm extensor muscle was taken from ultrasound images during wrist extension-flexion; we call this process sonomyography (SMG). SMG provides an alternative signal source for prosthetic control with proprioception. The fast block-matching algorithm was used to track the thickness deformation and then the opening and closing of the prosthetic fin...
متن کاملSonomyography: monitoring morphological changes of forearm muscles in actions with the feasibility for the control of powered prosthesis.
Electromyography (EMG) has been widely used for the assessment of musculoskeletal functions and the control of electrical prostheses, which make use of the EMG signal generated by the contraction of the residual muscles. In spite of the successful applications of EMG in different fields, it has some inherent limitations, such as the difficulty to differentiate the actions of neighboring muscles...
