Correlation between precise and simple tests in recovery of dynamic balance function after intravenous sedation with midazolam in the elderly

“…However, if a patient does not recovered sufficiently, he or she will decrease walking speed intentionally. It may be safer to perform this test after recognizing recovery with Romberg's test, which is less reliable but safer than the dynamic balance test [17]. Good correlation between the results of the TUG test and the CDP does not necessarily indicate that the reliability of the TUG test for detecting the suppression of balance is close to that of the CDP.…”

Study on the usefulness of precise and simple dynamic balance tests for the evaluation of recovery from intravenous sedation with midazolam and propofol

“…The recovery of dynamic balance function assessed by CDP after the injection of midazolam for intravenous sedation has been reported [5,[9][10][11], but no studies on propofol sedation have been reported. We confirmed that propofol is more suitable than midazolam for intravenous sedation in the outpatient clinic with regard to street fitness using precise and simple dynamic balance tests in the present study.…”

“…We previously reported that the intentional body sway test was useful for the evaluation of recovery from intravenous sedation in the elderly, but was not suitable for young adults [11]. CDP is classified according to the types of postural control as CDP using an intentional postural sway task [11,18,19] and CDP using perturbation stimuli [5,9,10]. As falls may occur in any direction in daily life, multidirectional mechanical perturbation is a desirable stimulus condition for CDP [20].…”

A simple posturographic method detects the difference in recovery of patients receiving endoscopic sedation with propofol vs. midazolam

“…Previous studies of sedation effects on postural stability focused on computerized dynamic posturography as it has greater sensitivity than static posturography. Fujisawa demonstrated that computerized dynamic posturography was affected by midazolam [1], that these effects persisted longer in the elderly than in young people [2], and that the effects were less persistent with propofol sedation [3]. These authors further demonstrated that the results of the timed up and go test, in which a patient stood up, walked five meters, turned, and returned to their chair, correlated with the computerized dynamic posturography score [3,4].…”
