Effectiveness of functional magnetic stimulation (FMS) technology on bladder contraction and bladder emptying was evaluated in twenty-two spinal cord injured subjects. FMS of the bladder was performed by stimulating the sacral nerves or the suprapubic region using a commercially available magnetic stimulator with a round coli. With sacral stimulation, the mean change in bladder pressure (Pves) was 24.4 +/- 4.88 cm H2O; with suprapubic stimulation, the mean change in Pves was 16.5 +/- 4.44 cm H2O. The change in Pves with sacral stimulation was higher than with suprapubic stimulation (p < .01). Seventeen subjects demonstrated voiding, either with sacral or suprapubic stimulation. Using a water-cooled coli, one subject demonstrated complete bladder emptying. FMS of the bladder has the potential to be a useful non-invasive technology for bladder emptying and bladder training in patients with neurogenic bladders.
The prevalence of carpal instability in a paraplegic population was investigated to establish an association between chronic repetitive stress on the wrist and the development of such instability. Nine of 162 paraplegic patients had static carpal instability and no history of an acute injury of the wrist. The predominant pattern of instability, found in eleven wrists (six patients), was non-dissociative volar intercalated segmental instability. The prevalence of carpal instability increased with the duration of weight-bearing on the upper extremity. Eighteen per cent of the patients in whom the spinal cord injury had occurred more than twenty years before the study had carpal instability. Carpal instability in these weight-bearing upper extremities and the increase in its prevalence with the duration of the forces across the wrist demonstrate an association between chronic repetitive stress on the wrist and carpal instability.
Spinal cord injury rehabilitation strives to provide the opportunity for persons with an acquired disability to lead a fruitful and satisfying personal and vocational life. The delivery of proper rehabilitation care to these patients involves the establishment of a continuum of services that includes the emergency medical system, the acute and rehabilitation hospital stay, and a program for lifetime health maintenance. As the patient regains health and confidence in his abilities, successful adjustment is promoted by separating the disabled person from a dependence on medical systems, redirecting the life focus back to family, and addressing vocational and social issues.
Accurate, noninvasive testing for deep venous thrombosis (DVT) by conventional methods is often not possible in the rehabilitation patient. Lower extremity amputation, a cast or bandage, or skin problems present obstacles to standard diagnostic methods. This report describes the use of duplex ultrasound (US) scanning for noninvasive diagnosis of DVT in a seventy-year-old man with a below-knee amputation, on whom Doppler and plethysmography examinations could not be performed. As experience is gained with this technique, the use of venography for diagnosis of DVT becomes more difficult to rationalize.
Superior mesenteric artery syndrome is a condition in which the third portion of the duodenum is intermittently compressed by the overlying superior mesenteric artery, resulting in gastrointestinal obstruction. Predisposing factors include rapid weight loss, prolonged supine positioning, and using a spinal orthosis, all of which are common among acute traumatic quadriplegic patients. This paper presents three patients, aged 24, 16, and 20 years, with traumatic quadriplegia treated with supine positioning and cervical orthoses, who had postprandial nausea and emesis, bloating, and abdominal pain during rehabilitation. Upper gastrointestinal radiographic series demonstrated abrupt duodenal obstruction to barium flow in all three patients. Two of the patients had complete relief of symptoms with conservative management, and one required surgical duodenojejunostomy. Enhanced awareness of this condition may result in improved recognition of this disease as a cause of persistent, unexplained gastrointestinal disturbances in quadriplegic persons, thereby optimizing its treatment and reducing its potential morbidity.
