Joint torque feedback is a new and intuitive way of delivering kinesthetic to person or guiding them during motion tasks via wearable devices. In this study, we performed three experiments understand how the elbow joint responds guidance small torques ( $ < \!1$ Nm). We first applied open-loop pulses elbow, determined ma...

A forty-three-year-old Indian stepped on a sharp piece of wood and suffered a small puncture wound on the sole of the right foot. A doctor gave him daily injections of penicillin for three days, but no antitetanus serum. Ten days after the injury he was admitted to hospital complaining of pains in his legs, and trismus was observed. He was immediately given an intravenous injection of 100,000 u...

OBJECTIVE To assess improvements in fixation stability when a hinged unilateral external fixator is used to supplement compromised internal fixation for distal humerus fractures. METHODS Removing a 1-cm section of the distal humerus in cadaveric whole-arm specimens created a comminuted distal humerus fracture model (AO type 13-A3). Fixation was then performed using different constructs repres...

OBJECTIVE The main purposes of this study were to examine, in subjects with chronic hemiparesis following a stroke: (i) the correlations between tests of muscle tone, stiffness, spasticity, paresis and co-contraction, and (ii) the correlations of these tests and measurements of impairment to upper extremity motor performance. DESIGN Prospective, cross-sectional, correlation matrix using sampl...

BACKGROUND Complex intra-articular distal humerus fractures are relatively uncommon injuries but are fraught with poor outcomes such as malunion, elbow stiffness and deformity. Various types of internal fixation screw-plate constructs have been developed to improve fixation. Specifically, a 90 degrees offset periarticular system lowers the profile on the lateral epicondyle, yet it is unclear ho...

BACKGROUND Because of strong loads acting in the elbow joint, intraarticular fractures with a methaphyseal comminuted fracture site at the distal humerus demand a lot from the osteosynthetic care. Ambiguities arise concerning to the anatomic position of the implants and the resulting mechanic performance. The aim of this biomechanical study was to compare the performance of different anatomical...
