ABSTRACT Targeted reinnervation is a surgical technique developed to increase the number of myoelectric input sites available to control an upper-limb prosthesis. Because signals from the nerves related to specific movements are used to control those missing degrees-of-freedom, the control of a prosthesis using this procedure is more physiologically appropriate compared to conventional control. This procedure has successfully been performed on three people with a shoulder disarticulation level amputation and three people with a transhumeral level amputation. Performance on timed tests, including the box-and-blocks test and clothespin test, has increased two to six times. Options for new control strategies are discussed.

    Article: Assessing the state of clinically applicable research for evidence-based practice in prosthetics and orthotics.

    [show abstract] [hide abstract]
    ABSTRACT: Evidence-based practice combines a practitioner's training and experience with evidence established through scientific research. Fundamental to the evidence-based process for prosthetics and orthotics is the ongoing availability of clinically applicable research on relevant conditions, components, and patient populations. In the past, research has been successfully applied to practice, sometimes producing substantial changes. Examples include clinically applicable research that has assessed treatment effectiveness, altered clinical patient interaction, led to the development of new components and technologies, and challenged or changed long-standing clinical opinion. Despite past successes, obstacles remain in the application of research to practice. Practitioners have stated a desire for research and have identified a list of research needs but lack the training or resources necessary to conduct the research. A gulf also exists between the perceived research needs and the clinically applicable research that is being produced, possibly because of the broad nature of those needs.

    ABSTRACT: The restoration of complex hand functions by creating a novel bidirectional link between the nervous system and a dexterous hand prosthesis is currently pursued by several research groups. This connection must be fast, intuitive, with a high success rate and quite natural to allow an effective bidirectional flow of information between the user's nervous system and the smart artificial device. This goal can be achieved with several approaches and among them, the use of implantable interfaces connected with the peripheral nervous system, namely intrafascicular electrodes, is considered particularly interesting. Thin-film longitudinal intra-fascicular electrodes were implanted in the median and ulnar nerves of an amputee's stump during a four-week trial. The possibility of decoding motor commands suitable to control a dexterous hand prosthesis was investigated for the first time in this research field by implementing a spike sorting and classification algorithm. The results showed that motor information (e.g., grip types and single finger movements) could be extracted with classification accuracy around 85% (for three classes plus rest) and that the user could improve his ability to govern motor commands over time as shown by the improved discrimination ability of our classification algorithm. These results open up new and promising possibilities for the development of a neuro-controlled hand prosthesis.

    Article: Design of a Multifunctional Anthropomorphic Prosthetic Hand With Extrinsic Actuation
    S.A. Dalley, T.E. Wiste, T.J. Withrow, M. Goldfarb
    [show abstract] [hide abstract]
    ABSTRACT: This paper presents an anthropomorphic prototype hand prosthesis that is intended for use with a multiple-channel myoelectric interface. The hand contains 16 joints, which are differentially driven by a set of five independent actuators. The hand prototype was designed with the minimum number of independent actuators required to provide a set of eight canonical hand postures. This paper describes the design of the prosthesis prototype, demonstrates the hand in the desired eight canonical postures, and experimentally characterizes the force and speed capability of the device. A video is included in the supplementary material that also illustrates the functionality and performance of the hand.
