In this article the design of a new upper limb rehabilitation system will be presented. A lightweight, modular, and portable system is achieved by the combination of electromyographic (EMG) control, functional electrical stimulation (FES), and the use of miniaturized flexible fluidic actuators (FFA) integrated in an elbow orthosis. First, the state of the art of upper limb rehabilitation devices will...
The rehabilitation arm is an upper limb orthosis for those with severe upper limb disabilities. The orthosis works by keeping certain arm positions and power assisting motions for the patient wearing the rehabilitation arm. It is designed for those who are able to make small movements in their arms. This robot has a bi-articular muscle type HBSA in its upper limb portion and the mechanism of the forearm...
This paper reports on the powered elbow orthosis for orthopaedic rehabilitation project and its main challenges. The mechanical design is briefly discussed. The actuator being used is the novel rotational actuator, MACCEPA or Mechanically Adjustable Compliance and Controllable Equilibrium Position Actuator. The schematic representation and working principle of this actuator are recapitulated in short...
Rehabilitation robotics is a young discipline that will become an imperative when the age of the population rises. The orthopaedic rehabilitation of the elbow joint poses some interesting challenges, discussed in this paper. There is a major difference between neuro-rehabilitation and orthopaedic rehabilitation and thus in the approaches necessary to tackle its challenges. Moreover, the elbow joint...
This paper presents a novel design for a 4 degree of freedom pneumatically-actuated upper-limb rehabilitation device. BONES is based on a parallel mechanism that actuates the upper arm by means of two passive, sliding rods pivoting with respect to a fixed structural frame. Four, mechanically-grounded pneumatic actuators are placed behind the main structural frame to control shoulder motion via the...
This paper presents the design of IKO (IKerlanpsilas Othosis), an upper limb exoskeleton oriented to increasing human force during routine activity at the workplace. It can be considered as a force amplification device, conceived to work in collaboration with the human arm and implementing biomimetic principles. The proposed design is intended to find the best compromise between maximum reachable...
