Elbow disorders are a common occurrence; however, our understandings of complex elbow dislocation and the functional anatomy of the elbow joint are still very limited. The efficacy of treatment strategies of this injury is largely unknown. The purpose of this study is to create an active elbow simulator using a new paradigm, In vitro joint simulation driven by in vivo motion, to study how elbow injuries...
Numerous haptic devices have been developed for neurorehabilitation of upper extremities, but their wide-spread use has been largely impeded for reasons of complexity and cost. In this paper we describe a variable structure pantograph mechanism that produces a versatile rehabilitation robot for movement training of the shoulder, elbow, and wrist. The device has three operational modes: ARM, REACH...
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...
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...
