“…It is different from a prosthetic where a device substitutes a missing body part. External devices, such as dental braces, insoles, or a pair of glasses are examples of orthotic devices (Sarakoglou, Tsagarakis, & Caldwell, 2004). Active orthoses are limited by the daunting issue that the specific nature of disability varies from one person to another.…”

This literature review of exoskeleton design provides a brief history of exoskeleton development, discusses current research of exoskeletons with respect to the innate human-machine interface, and the incorporation of exoskeletons for ergonomic intervention, and offers a review of needed future work. Development of assistive exoskeletons began in the 1960's but older designs lacked design for human factors and ergonomics and had low power energy density and power to weight ratios. Advancements in technology have spurred a broad spectrum of research aimed at enhancing human performance and assisting in rehabilitation. The review underwent a holistic and extensive search and provides a reflective snapshot of the state of the art in exoskeleton design as it pertains to the incorporation of exoskeletons for ergonomic intervention. Some of the remaining challenges include improving the energy density of exoskeleton power supplies, improving the power to weight ratio of actuation devices, improving the mechanical human-machine interface, and dealing with variability between users.

Previous studies demonstrated that bimanual coordination can assist to rehabilitation program for patients with hemiplegia by improving their motor functions. Moreover, in addition to the rehabilitation assistance, bimanual coordination can also be used for prosthesis users to improve the usability of prosthesis. Intention detection and motion control algorithms for one hand case have been investigated in many studies in the literature. On the other hand, only few studies have focused on the model of bimanual coordination, and these studies are lack of the sufficient investigation of kinematic and dynamic parameters of the models. The purpose of this study was to model the bimanual coordination for developing rehabilitation support robots and prosthetic arms. In this study, artificial neural networks (ANN) were employed to examine the kinematic and dynamic parameters by taking them as feature vectors to ANN for defined bimanual tasks. For this purpose, two different ANN algorithms were selected; i) Back Propagation Neural Network (BPNN), and ii) Radial Basis Function Network (RBFN). The parameters were calculated from the results of a set of experiment, in which 3 different bimanual coordination tasks were recorded. Training time, test time, and error rate were used as evaluation criteria for performance analysis and comparison of the models. As a result, it was made clear that, bimanually coordinated behavior could be predicted at a certain level of error rate, within acceptable computation time, moreover, the trajectory input is important to predict the behavior of the bimanual coordination, furthermore, BPNN is more robust for non-periodic movement than RBFN.

“…However, devices providing external support for exercising the fingers after surgery have been reported. These are available in the form of exoskeletons [3], functional electrical stimulation [4] devices, and virtual reality based systems [5]- [7]. There is also a simple device by name therapeutic putty, using which the patient can massage his fingers and facilitate movement by applying pressure on the blob of putty of varying stiffnesses.…”

Conceptualization and development of a novel device to monitor mobilization of fingers of a patient suffering from post-traumatic stiffness of the tendons is presented in this paper. Effectiveness of the treatment depends largely on this component of recovery and is unfortunately beyond the scope of continuous vigil by the doctor. The major post-operative procedure is to keep flexing and extending the fingers, either independently or with external support, usually with the other hand. The patient has to do this diligently and hence monitoring this exercise is of concern. The proposed novel idea is a monitoring system which keeps track of the movements of the fingers using linear ratiometric Hall-effect sensors (Allegro-1321) and magnets attached to the fingers. This can provide reliable data to the doctor to ascertain whether the patient is actually doing his part in effecting a speedy recovery for himself, thus improving the overall efficacy of the treatment.
