Filter by:The primary purpose of this study is to assess whether lumbar spine surgery patients with dura rupture differ in symptom prevalence and severity from other lumbar spine surgery patients in the early postoperative phase. This is in order to develop a symptom-specific mobilization algorithm (DURAMOB) that can be used to assess whether patients with dura rupture safe can be mobilized earlier after lumbar back surgery to prevent bed rest complications
To compare the reduction of the bedrest time of the patient after percutaneous renal biopsy from 24 hours to 8 hours in relation to the occurrence of complications evaluated by the Nursing Outcome Classification (NOC) indicators.
The aim of the pilot trial is to assess at what extend women with arrested threatened preterm labor change their activity patterns at home in response to bed rest prescription. An area of concern for the design of a trial is the strength of health provider's recommendation to change women's behaviors, and their compliance with bed rest recommendations. The study was a randomized parallel design. The intervention group consisted of total bed rest for four days (with allowance to go to the toilet). The control group consisted in the restriction of activities during four days.
The purpose of this research sub-study is to determine the changes in heart function during the bedrest period using ultrasound and MRI. This topic is important for medical care of astronauts in space. It can enable physicians on the ground to monitor exercise protocols that are used to prevent deconditioning-loss of strength during long space flights. Your participation in this study would include ultrasound examinations with bicycle exercise before, during, and after the 12-week bedrest period. MRI exams would be performed before and after the bedrest period. Each echo exam may last up to 1 hour. This time will be required to perform an ultrasound examination before and during supine (lying down) bicycle exercise. The exercise period will be approximately 10-15 minutes. The bicycle exercise will be a symptom-limited test. This means that the test will be stopped if you experience any discomfort. An ultrasound examination of your heart will be done to assess heart function. You will be asked to lie on your left side on an examination table while a technician takes pictures of your heart with a small probe that is gently pressed against your chest after applying a gel. The ultrasound data will be processed to evaluate myocardial strain, a value that may be useful in describing heart function. Each MRI may last up to 1 hour. An MRI obtains body pictures created by using magnetic energy rather than x-ray energy. To have the scan, you will lie on a table that slides into the scanner, which is like a large tube. An MRI examination of your heart will be done to assess heart function. You will be asked to lie still and follow simple breathing instructions during the procedure. The MRI data will be processed to evaluate the volume of blood being pumped by your heart, a value that may be useful in describing heart function.
