    ELECTRODES INSTALLED IN ROLL-ON SUSPENSION SLEEVES
    (2002) Daly, Wayne K.
    This presentation describes transhumeral and transradial prostheses which have been successfully fit to patients using electrodes installed in roll-on suspension sleeves. Metal electrodes and modified wiring systems have been developed and tested along with techniques for installing electrodes in roll-on sleeves to provide improved suspension and electrode contact. This series of patients has shown that a Roll-on sleeve is an excellent way to achieve superior suspension and greater range of motion. Information will be presented to document the increase in suspension and range of motion in several patients who were fit with both traditional and roll-on suspension systems. This design maintains consistent electrode contact for patients, especially those who have volume changes or experience difficulty with the traditional suspension methods. This system is adaptable to many prosthetic hand and elbow systems and amputation levels. Future research directions will be suggested to improve this system and make it available to a wider population of users.

    Integrating Electrodes in Silicone and a New Application for Myoelectric Suction Sockets
    (2005) Ramdial, Sandra
    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.
