    Clinical Trials of the new Boston Digital(tm) Arm System
    (2002) Farnsworth, Troy; Limehouse, Bill; Hanson, Bill; Mandacina, Steve
    Microprocessor-based controllers for upper-limb powered prostheses have made significant advances over the past few years. These devices allow prosthetists to evaluate the patient and set-up prosthetic controls to optimize performance for the user. This enables the user to obtain a controller that is customized to suit their specific needs and capabilities. The new Boston Digital(tm) Arm System is the first powered elbow prosthesis to offer this advanced technology. This System serves as a “platform” for upper-limb prosthetic control. With five motor controllers, the Boston Digital Arm System can operate hands grippers, wrist rotators, shoulder lock actuators and more. The System is universal − it works with prosthetic devices from any manufacturer, allowing prosthetist to create the optimal prosthesis for their client.

    Hybrid Approach to Bilateral UE Prosthetic Rehabilitation
    (2002) Farnsworth, Troy; Limehouse, Bill; Mandacina, Steve; Ullendhal, Jack
    Patients with “high” level bilateral upper extremity deficiencies require maximum functional rehabilitation to increase independence and self-care skills. Traditional prosthetic rehabilitation for these individuals utilizes various control mechanisms including body power, electric, and hybrid systems. Rehabilitation teams rarely gain experience with multiple cases using varied control methods. In most cases systems are recommended and fit based on the limited past experiences and training of the rehabilitation team members and the local prosthetist.

    MANAGEMENT OF HIGH LEVEL BILATERAL ARM AMPUTEES WHO USE WHEELCHAIRS FOR MOBILITY
    (2005) Uellendahl, Jack E.; Farnsworth, Troy; Limehouse, Bill; Heckathorne, Craig
    Management of the high-level bilateral arm amputee poses many challenges to the prosthetist and rehabilitation team. When the amputee is also in a wheelchair, use of arm prostheses becomes more difficult. Positioning of the prosthesis without the use of the lower extremities is remarkably difficult. The work envelop is further reduced when trunk motion and stability is compromised by paralysis. Heckathorne and Uellendahl have recommended a framework for component and control strategy selection when designing prostheses for high level bilateral arm amputees.1-3 This strategy calls for use of dissimilar components on each side to enhance prosthesis usefulness and control schemes that provide dedicated control of as many components as possible allowing simultaneous control when functionally desired. Uellendahl has used this approach for over 15 years for clinical fittings. The long-term success of this fitting philosophy demonstrates the clinical efficacy of this approach. In fact, one of the amputees (MM) reported on in this paper has used prostheses of the same original design for more than a dozen years
