The first part of this paper reviews different approaches to define the motion of the fingers and the thumb in order to obtain prehension. The last part presents the design of a hand prosthesis based on a new plane of action for the thumb and on proposed design specifications and functional characteristics. The design methodology consists of two steps: the(More)
A tridimensional (3-D) x-ray method of evaluation of the shoulder was contrasted with six clinical and radiologic techniques used to evaluate shoulder subluxation, in 50 hemiplegic subjects. The 3-D evaluation is obtained through a mathematical computation associating two x-rays of the same shoulder, one taken at 0 degree (anteroposterior) and the other at(More)
Inferior subluxation of the shoulder in hemiplegia was measured using a tridimensional (3-D) x-ray technique. This technique gave the true vertical distance separating the apex of the humeral head and the inferior margin of the glenoid cavity. Both shoulders of each subject were evaluated and the difference used as a measure of subluxation. This measure was(More)
In the present work, the load-bearing role of the facet joints in a lumbar I2-3 segment is quantitatively determined by means of a three dimensional nonlinear finite element program. The analysis accounts for both material and geometric nonlinearities and treats the facet articulation as a nonlinear moving contact problem. The disc nucleus is considered as(More)
An evaluation, based on the Bobath approach to treatment has been developed. A model, substantiating this evaluation is presented. In this model, the three stages of motor recovery presented by Bobath have been extended to six, to better follow the progression of the patient. Six parameters have also been identified. These are the elements to be quantified(More)
The preliminary results based on a one year study on the evolution and management of scoliosis are presented. Twenty-one patients were followed in the Neuro-Muscular Disease Clinic at Ste-Justine Hospital where standardized spinal radiographs were taken periodically with the Scoliosis Chariot and the Throne. The short period of observation as well as the(More)
A protocol of evaluation of the hemiplegic patient based on the Bobath approach to treatment is presented. Six parameters are evaluated: sensorium, muscle tone, reflex activity, active movement, postural reactions and pain. The first and last of these are included because of their possible effects on the motor recovery process of the hemiplegic patient. The(More)
Sixty-two hemiplegic subjects were treated with the Bobath approach for a period of three months. During this time they were evaluated on three occasions. The testing battery consisted of a Bobath evaluation, the Brunnstrom scale, the Fugl-Meyer test, the Upper Extremity Functional Test (UEFT) and the Present Pain Intensity (PPI) of the McGill pain(More)
