Rehabilitation Medicine Summit: Building Research Capacity--executive summary.
The advancement of medical science depends on the production, availability, and utilization of new information generated by research. A successful research enterprise depends not only on a carefully designed agenda that responds to clinical and societal needs but also on the research capacity necessary to perform the work. Research that is likely to enhance clinical practice presupposes the existence of a critical mass of investigators working as teams in supportive environments. Unfortunately, far too little research capacity of that kind exists in rehabilitation medicine to ensure a robust future for the field. The "Rehabilitation Medicine Summit: Building Research Capacity" was conceptualized as a way of fashioning a long-term plan to foster the required developments.

Functional electrical stimulation for neuromuscular applications.
Paralyzed or paretic muscles can be made to contract by applying electrical currents to the intact peripheral motor nerves innervating them. When electrically elicited muscle contractions are coordinated in a manner that provides function, the technique is termed functional electrical stimulation (FES). In more than 40 years of FES research, principles for safe stimulation of neuromuscular tissue have been established, and methods for modulating the strength of electrically induced muscle contractions have been discovered. FES systems have been developed for restoring function in the upper extremity, lower extremity, bladder and bowel, and respiratory system. Some of these neuroprostheses have become commercialized products, and others are available in clinical research settings. Technological developments are expected to produce new systems that have no external components, are expandable to multiple applications, are upgradable to new advances, and are controlled by a combination of signals, including biopotential signals from nerve, muscle, and the brain.

Simulated neuroprosthesis state activation and hand-position control using myoelectric signals from wrist muscles.
This paper reports on the initial phase of feasibility testing of a control strategy that uses myoelectric signals (MES) from wrist flexor and extensor muscles to control a hand-grasp neuroprosthesis for C7 tetraplegia. The control strategy was customized to the MES patterns produced during wrist flexion, extension, and relaxation for five able-bodied subjects and two individuals with C7 spinal cord injury. We evaluated the reliability with which the subjects could deliberately activate target neuroprosthesis states and control the degree of opening and closing of a computer-simulated hand using the myoelectric control strategy. Every subject was able to activate at least 99% of the target states for at least 1 continuous second, enough time to prove the activation was deliberate and to achieve significant hand opening or closing. Additionally, every subject was able to control the opening and closing of the simulated hand with enough proficiency to match greater than 87% of the target hand positions for at least 2 continuous seconds. Most of the inadvertent disturbances in simulated hand position were of a magnitude less than 10% of full range of motion for every subject. Future studies will incorporate the control strategy into an electrical stimulation system that opens and closes the hand of an individual with C7 tetraplegia.

Satisfaction with upper-extremity surgery in individuals with tetraplegia.
OBJECTIVE: To measure the satisfaction of individuals with tetraplegia with their upper-extremity reconstructive surgery. DESIGN: Survey. SETTING: Two Spinal Cord Injury Model Systems centers. PARTICIPANTS: Sixty-seven individuals with spinal cord injury at the C4 through C8 motor level (107 arms). INTERVENTIONS: Participants had upper-extremity surgery to improve function. The surgical procedures included tendon transfers for elbow extension, wrist extension, hand grasp, and pinch or hand grasp neuroprosthesis. MAIN OUTCOME MEASURE: A survey was mailed to participants, who were asked to respond to statements such as, "If I had it to do over, I would have the hand/arm surgery again," using a 5-level Likert scale (ranging from strongly agree to strongly disagree). RESULTS: Seventy percent of the participants were generally satisfied with the results of their upper-extremity surgery, 77% reported a positive impact on their lives, 68% reported improvements in activities of daily living (ADLs), 66% reported improved independence, 69% reported improvement in occupation, 71% reported improved appearance or neutral, 78% reported their hand worked as well (or neutral) as it did when surgery was first performed, and 86% reported postoperative therapy as being beneficial. CONCLUSIONS: Upper-extremity surgery had a positive impact on life, increased ability to perform ADLs and to be independent, and improved quality of life.

An advanced neuroprosthesis for restoration of hand and upper arm control using an implantable controller.
An advanced neuroprosthesis that provides control of grasp-release, forearm pronation, and elbow extension to persons with cervical level spinal cord injury is described. The neuroprosthesis includes implanted and external components. The implanted components are a 10-channel stimulator-telemeter, leads and electrodes, and a joint angle transducer; the external components are a control unit and transmitter-receiver coil. The system has completed preclinical testing and has been implanted fully in 3 persons and partially in 1 person, all with tetraplegia caused by spinal cord injury at C5 and C6. The minimum follow-up time for any system component is 16 months. All subjects had improvements in grasp strength, range of motion, and ability to grasp objects and increased independence in activities of daily living. Each subject became a regular user of the neuroprosthesis and is satisfied with it. The implanted components have not caused any medical complications. The operation of the electrodes and sensors has been stable. The data show that this advanced neuroprosthetic system is safe and can provide grasping and reaching ability to individuals with cervical level spinal cord injury.

Opportunities and challenges for the clinical utilization of functional electrical stimulation.
Clinical applications of electrical stimulation for effecting change in the damaged or disabled nervous system are in their infancy. This technique is extremely powerful, because any neural structure that is electrically excitable can potentially be affected. Although early attempts to apply electrical stimulation were limited by insufficient physiological knowledge and undeveloped technology, developments over the past two decades now provide a strong base for clinical applications. Clinical systems for bladder control and respiration have been in use for many years. Some applications of FES to restore hand function and walking are in multicenter testing, whereas many others are being studied for clinical feasibility at single sites. Applications are focusing on safety and efficacy, as well as on clinical outcome measures to address the issues posed by the regulatory and reimbursement processes. As clinical systems become more routine, issues of multiple system applications will need to be addressed. Present and future applications of functional electrical stimulation may be expected to significantly enhance independence and improve the quality of life for individuals with central nervous system dysfunction.

Durability of implanted electrodes and leads in an upper-limb neuroprosthesis.
Implanted neuroprosthetic systems have been successfully used to provide upper-limb function for over 16 years. A critical aspect of these implanted systems is the safety, stability, and-reliability of the stimulating electrodes and leads. These components are (1) the stimulating electrode itself, (2) the electrode lead, and (3) the lead-to-device connector. A failure in any of these components causes the direct loss of the capability to activate a muscle consistently, usually resulting in a decrement in the function provided by the neuroprosthesis. Our results indicate that the electrode, lead, and connector system are extremely durable. We analyzed 238 electrodes that have been implanted as part of an upper-limb neuroprosthesis. Each electrode had been implanted at least 3 years, with a maximum implantation time of over 16 years. Only three electrode-lead failures and one electrode infection occurred, for a survival rate of almost 99 percent. Electrode threshold measurements indicate that the electrode response is stable over time, with no evidence of electrode migration or continual encapsulation in any of the electrodes studied. These results have an impact on the design of implantable neuroprosthetic systems. The electrode-lead component of these systems should no longer be considered a weak technological link.

Implementation of an implantable joint-angle transducer.
An implantable joint-angle transducer (IJAT) was implemented to provide command-control information from the wrist for functional neuromuscular stimulation (FNS) neuroprostheses. The IJAT uses the Hall effect to sense joint angle. The objectives of this study were to evaluate (1) chronic functionality, (2) safety and biocompatibility, (3) repeatability of the implantation procedure, and (4) clinical feasibility. Accelerated bench testing projected an operating period of over 50 years. In chronic animal experiments, stable output was obtained from three of four IJATs for periods of 10 to 19 months. Histology revealed acceptable osseointegration of the implant. The device has been implanted in human subjects for over 2 years and provides an excellent control signal for hand grasp. We conclude that this device is safe and effective for chronic human use as a control input for an implanted hand neuroprosthesis.
