Abstract:
There have been numerous attempts to integrate electrodes into liners to operate externally powered devices. Various methods and techniques have been tried from RTV laminated sockets to off-the-shelf liners as well as a number of thermoplastic techniques. All of these techniques, while providing improved suspension and comfort have limitations and drawbacks. However these limitations have not deterred prosthetists from pursuing these options in an effort to provide better control, better suspension and ultimately a better outcome. Through the experience of Otto Bock’s Custom Silicone Services, we will present a number of solutions. These include challenging fittings such as the transmetacarpal as well as more standard levels.
Suction Sockets have been utilized in upper extremity fittings for many years now, but it has always been challenging to maintain suction in myoelectric fittings due to the difficulty of sealing around electrodes. A new solution developed by Otto Bock will also be presented.
