WebJan 6, 2024 · Background. Most commercial bionic hands currently utilize a dual-site myoelectric sensor system to implement user control. Two sensors are placed on the residual limb’s skin to detect different muscle movements via electrical signals. One muscle movement triggers a close action in the bionic hand, while the other triggers an open action. WebFor management of the individual with transradial amputation, myoelectric control is considered by many of the professionals specializing in the treatment of individuals with upper-limb amputation as the standard of care. 2 This is not to say that body-powered prostheses do not have a place in contemporary management of persons with upper-limb ...
