A new concept of dynamic orthosis for paraplegia: the weight bearing control (WBC) orthosis.
A new concept of device, termed the weight-bearing control (WBC) orthosis, has been designed with three major needs in mind; a rigid frame that supports the user's body weight, a special hip joint device that reciprocally propels each leg forward, a gas powered foot device that varies the sole thickness of the device for foot/floor clearance, and control system of the orthosis. A paraplegic (T7...
متن کاملThree-Dimensional Dynamic Fracture Analysis Using the Material Point Method
This paper describes algorithms for threedimensional dynamic stress and fracture analysis using the material point method (MPM). By allowing dual velocity fields at background grid nodes, the method provides exact numerical implementation of explicit cracks in a predominantly meshless method. Crack contact schemes were included for automatically preventing crack surfaces from interpenetration. ...
متن کاملThree-dimensional evaluation of lumbar orthosis effects on spinal behavior.
The effects of the lumbosacral Lumbostab orthosis on intervertebral mobility, spinal geometry, and the geometrical deformations of discs have been investigated with a three-dimensional (3-D) reconstruction technique of the lumbar spine. Positions studied are neutral standing, maximal flexion, extension, left lateral bending, and left axial rotation. Results from this preliminary study indicate ...
متن کاملA new dynamic foot abduction orthosis for clubfoot treatment.
Recurrent clubfoot deformity after successful initial correction with the use of the Ponseti method continues to be a common problem and is often caused by noncompliance with wear of the traditional foot abduction brace. The purpose of this study was to assess the results of a newly designed dynamic foot abduction orthosis in terms of (1) parental compliance and (2) effectiveness in preventing ...
متن کاملThree Point Arcwise Convexity
Let 5 be a set in a two dimensional Euclidean space E2. Such a set 5 is said to be arcwise convex [5] if each pair of its points can be joined by a convex arc lying in S. A convex arc is, by definition, an arc which is contained in the boundary of a plane convex set. In two previous papers, [5; 6], the author studied certain properties of closed arcwise convex sets. It is the purpose of this pa...
