From 1973 to 1981, 94 patients suffering from low-back pain, with or without spread into the lower extremities, were candidates for therapeutic spinal cord stimulation. The etiology of pain in all cases was lumbosacral spinal fibrosis due to multiple myelographies and surgical interventions on the lumbar spine. The long-term results, based on a four-year(More)
OBJECTIVE To evaluate the performance of three tele-echography systems for routine use in isolated medical centers. METHODS Three systems were used for deep (abdomen, pelvis, fetal) and superficial (muscle, thyroid, carotid artery) examinations: (a) a robotic arm (RA) holding an echographic probe; (b) an echograph with a motorized probe (MP); and (c)(More)
PURPOSE The objective of this study was to design and validate a "Tele-Operated UltRasound System" ("TOURS") to perform ultrasound examinations on patients located in isolated areas. MATERIALS AND METHODS A commercially available portable echograph was modified to allow functions (Doppler, two-dimensional, three-dimensional, elastography, etc.) and(More)
Voltage and current within Gasserian ganglion have been measured during a therapeutical high frequency coagulation of the Gasserian ganglion in 25 consecutive cases. From these values, the impedance (Ohm), the work (Watt) and the total energy (Joule) necessary to obtain an analgesia without anesthesia have been calculated. The study has shown that the(More)
