“…The MIME unilateral modes were roughly patterned after the hands-on interactions that therapists use, and a novel bilateral mode was developed to assist mirror image movements. Early research recognized that bilateral exercises might provide advantages to similar unilateral movements [19][20], and a theoretical rationale for bilateral mirror image movements was developed [18]. Interestingly, two additional research groups have since developed robotic devices for bilateral stroke therapy [21][22], and their preliminary results indicate the devices are effective.…”

Abstract-This study presents results from a randomized controlled clinical trial of the Mirror Image Movement Enabler (MIME) robotic device for shoulder and elbow neurorehabilitation in subacute stroke patients, including data on the use of its bilateral training mode. MIME incorporates a PUMA 560 robot (Staubli Unimation Inc, Duncan, South Carolina) that applies forces to the paretic limb during unilateral and bilateral movements in three dimensions. Robot-assisted treatment (bilateral, unilateral, and combined bilateral and unilateral) was compared with conventional therapy. Similar to a previous study in chronic stroke, combined unilateral and bilateral robotic training had advantages compared with conventional therapy, producing larger improvements on a motor impairment scale and a measure of abnormal synergies. However, gains in all treatment groups were equivalent at the 6-month follow-up. Combined unilateral and bilateral training yielded functional gains that were similar to the gains from equivalent doses of unilateral-only robotic training, although the combined group had more hypertonia and less movement out of synergy at baseline. Robot-assisted treatment gains exceeded those expected from spontaneous recovery. These results are discussed in light of the need for further device development and continued clinical trials.

“…Different from the electromechanical devices for passive motion rehabilitation (such as the Artromot system of the ORTHOMED Medizintechnik Ltd) [see 5) in the Appendix], a recent trend is to develop robotic-based systems for movement rehabilitation. The related systems are the robotic device for stroke rehabilitation in the GENTLE/S Project [93], the robotic therapy system, called Stanford Driver's SEAT [94], the MIME project [95] of the VA Palo Alto Rehabilitation R&D Center, the robotic system for neuro-rehabilitation of the Newman Laboratory at the Massachusetts Institute of Technology (MIT) [96], and the system of the University of California, Irvine [97]. These robotic systems can be programmed to implement different Fig.…”

Abstract-Smart houses are considered a good alternative for the independent life of older persons and persons with disabilities. Numerous intelligent devices, embedded into the home environment, can provide the resident with both movement assistance and 24-h health monitoring. Modern home-installed systems tend to be not only physically versatile in functionality but also emotionally human-friendly, i.e., they may be able to perform their functions without disturbing the user and without causing him/her any pain, inconvenience, or movement restriction, instead possibly providing him/her with comfort and pleasure. Through an extensive survey, this paper analyzes the building blocks of smart houses, with particular attention paid to the health monitoring subsystem as an important component, by addressing the basic requirements of various sensors implemented from both research and clinical perspectives. The paper will then discuss some important issues of the future development of an intelligent residential space with a human-friendly health monitoring functional system. Index Terms-Health monitoring, intelligent house, smart house, wearable sensor.

“…However, none of the existing exoskeleton designs have the potential to be lightweight and easy to be worn continuously. Some wellknown designs to evaluate and treat upper extremity functions for post-stroke rehabilitation of patients employing robotic technology are ARM [2], MIME [3] and MIT-MANUS [4]. However, none of these were meant to be portable support devices.…”

This paper presents the design of a wearable upper arm exoskeleton that can be used to assist and train arm movements of stroke survivors or subjects with weak musculature. In the last ten years, a number of upper-arm training devices have emerged. However, due to their size and weight, their use is restricted to clinics and research laboratories. Our proposed wearable exoskeleton builds upon our extensive research experience in wire driven manipulators and design of rehabilitative systems. The exoskeleton consists of three main parts: (i) an inverted U-shaped cuff that rests on the shoulder, (ii) a cuff on the upper arm, and (iii) a cuff on the forearm. Six motors, mounted on the shoulder cuff, drive the cuffs on the upper arm and forearm, using cables. In order to assess the performance of this exoskeleton, prior to use on humans, a laboratory test-bed has been developed where this exoskeleton is mounted on a model skeleton, instrumented with sensors to measure joint angles and transmitted forces to the shoulder. This paper describes design details of the exoskeleton and addresses the key issue of parameter optimization to achieve useful workspace based on kinematic and kinetic models.
