Most transhumeral amputees report that their prosthetic device lacks functionality, citing the control strategy as a major limitation. Indeed, they are required to control several degrees of freedom with muscle groups primarily used for elbow actuation. As a result, most of them choose to have a one-degree-of-freedom myoelectric hand for grasping objects, a myoelectric wrist for pronation/supin...

Elbow dislocations are a common orthopedic injury, but the ideal reduction method remains elusive. The complex trochoginglymus anatomy of the joint, along with the close proximity to neurovascular structures, makes the elbow a challenge to reduce. Elbow dislocations occur at a rate of approximately 6 to 8 cases per 100,000 individuals and account for 10% to 25% of all elbow injuries annually.1 ...

When arm movements are perturbed by a load, how does the nervous system adjust control signals to reduce error? While it has been shown that the nervous system is capable of compensating for the effects of limb dynamics and external forces, the strategies used to adapt to novel loads are not well understood. We used a robotic exoskeleton [kinesiological instrument for normal and altered reachin...

Introduction Old neglected posterior type of elbow dislocations is not very common and generally requires open reduction. It was usually treated with open reduction and K-wire stabilization. We did a newer method in which in addition cruciate type ligament reconstruction; we have reconstructed lateral ulnar collateral ligament (LUCL) and UCL (medial collateral ligament) using semitendinosus gra...

We investigated swing-through axillary crutch gait (nonweight bearing on the left lower extremity) to determine the effects of gait speed, crutch length, and handle position on the forces exerted at the hands and on the moments exerted about the elbow joints. Ten healthy subjects, skilled in swing-through crutch gait, walked at three speeds using fitted crutches, at a fixed speed with four diff...

[Purpose] This research investigated the effect of angular variation of flexion of the elbow joint on the muscle activation of elbow flexor muscles. [Subjects] The research subjects were 24 male college students with a dominant right hand who had no surgical or neurological disorders and gave their prior written consent to participation with full knowledge of the method and purpose of this stud...

s: The objective of this meta-analysis was to determine the incidence and identify risk factors associated with heterotopic ossification after elbow trauma. CNKI, Embase, Medline, and Cochrane central database were searched using a broad range of terms to identify original research, published all through August 2015 and identified potentially studies. Qualified studies had to meet the quality a...

Our objective was to assess the mechanical changes associated with spasticity in elbow muscles of chronic hemiparetic stroke survivors and to compare these changes with those recorded in the ankle muscles of a similar cohort. We first characterized elbow dynamic stiffness by applying pseudorandom binary positional perturbations to the joints at different initial angles, over the entire range of...

Prominent in the L-shaped three-dimensional structure of tRNAs is the "elbow" where their two orthogonal helical stacks meet. It has a conserved structure arising from the interaction of the terminal loops of the D- and T-stem-loops, and presents to solution a flat face of a tertiary base pair between the D- and T-loops. In addition to the ribosome, which interacts with the elbow in all three o...

BACKGROUND Tennis elbow (TE) is a common musculotendinous degenerative disorder of the extensor origin at the lateral humeral epicondyle. Different modes of treatment are used for management of tennis elbow. OBJECTIVES This study investigated the effect of the taping technique (TT) on pain, grip strength and wrist extension force in treatment of tennis elbow. PATIENTS AND METHODS Thirty pat...
