Under dynamic conditions, aspects of arm movements have been explored in two conditions: supported and unsupported against gravity. While these methods have provided insight into movement patterns following stroke, the picture is incomplete and requires a device that can measure joint torques during dynamic arm motions and provide levels of partial support to the arm during movement. Here, we describe the arm coordination training 3-D (ACT/sup 3D/) robotic system and how its unique characteristics can provide additional insight into the dynamic expression of these synergies.

MIME incorporates a PUMA 560 robot that applies forces to the paretic limb during unilateral and bilateral 3-dimensional movements. The training dose was 15 1-hour sessions within a 4-week period. Analysis of clinical data found the MIME training at least as effective as an equivalent dose of hands-on therapy by a therapist. The MIME training provided added-value by increasing the rate of recovery on some motor impairment scales. Combined unilateral and bilateral training yielded similar functional outcomes compared to equivalent doses of unilateral-only robot training, but with reduced hypertonia and abnormal synergies. Robot group gains exceeded that expected from spontaneous recovery.","PeriodicalId":131431,"journal":{"name":"9th International Conference on Rehabilitation Robotics, 2005.

The device is based on the Wilmington Robotic Exoskeleton (WREX), a passive, mobile arm support developed for children with arm weakness caused by a debilitative condition. Previously, we scaled WREX for use by adults, instrumented it with potentiometers, and incorporated a simple grip strength sensor. The resulting passive device (Training WREX or \"T-WREX\") allows individuals with severe motor impairment to practice functional movements (reaching, eating, and washing) in a simple virtual reality environment called Java Therapy 2.0. However, the device is limited since it can only apply a fixed pattern of assistive forces to the arm. In addition, its gravity balance function does not restore full range of motion. Therefore, we are also developing a robotic version of WREX named Pneu-WREX, which can apply a wide range of forces to the arm during naturalistic movements. Pneu-WREX uses pneumatic actuators, non-linear force control, and passive counter-balancing to allow application of a wide range of forces during naturalistic upper extremity movements. Besides a detailed description of the mechanical design and kinematics of Pneu-WREX, we present results from a survey of 29 therapists on the use of such a robotic device.","PeriodicalId":131431,"journal":{"name":"9th International Conference on Rehabilitation Robotics, 2005.

Because of the severe consequence of falling, the detection method of the anti-collision system must be very reliable. However, many object detection techniques tend to miss targets that are unfavourably oriented or have certain surface properties. This research evaluated an uncommon method: laser line object detection (LLOD). The LLOD system projects an invisible infrared laser line onto the ground, and reads the resulting image via a camera. By analyzing the laser line in the image, the system can identify whether objects are in the target area. A pilot LLOD system was designed and installed on a powered wheelchair. The results of the evaluation experiments showed that the LLOD system can detect almost all obstacles with different orientations and materials, and produced a high detection rate on favourable flooring surfaces.","PeriodicalId":131431,"journal":{"name":"9th International Conference on Rehabilitation Robotics, 2005.

We present preliminary data for the development of a new technique for obtaining multiple electromyographic (EMG) signals for controlling multifunctional myoelectric hand and wrist prostheses. A completely embedded passive conductor is proposed to transmit intramuscular EMG signals to a distant location just beneath the skin surface with a subcutaneous terminal. These signals can then be recorded with conventional surface electrodes. The surface recorded intramuscular EMG (SRI EMG) signals would closely follow the electrical potential at the muscle fiber source. They would be extremely selective, and the well-known effect of spatial filtering, which reduces the amplitude and frequency content of surface EMG signals, would be virtually eliminated. It would, therefore, be possible to access control signals from deep or small muscles that would otherwise be unavailable. Based on this technique, a new generation of multifunction myoelectric prostheses can be developed. The technique is a simple, inexpensive, and robust alternative to implanted telemetry systems and percutaneous electrodes.","PeriodicalId":131431,"journal":{"name":"9th International Conference on Rehabilitation Robotics, 2005.
