“…Others use body markers, often located near or on the head [17][18][19], or on the hips [20,21]. Although the relationship between the movements of different body points in space has already been documented [22][23][24][25][26], little is known about the reliability of each method for the assessment of postural steadiness.…”

“…In so far as variability is concerned, our study confirms previous work using sway magnetometry, which suggests that length of COP is the measurement of choice for analysis of body sway, since it is the least variable. [1] But, since the absolute differences in A95 are so large, that outweighs its greater variability.…”

“…The AccuSway PLUS system (Advanced Mechanical Technology, Inc., Watertown, MA, USA) is a commercially available, computerised system for measuring body sway. [1][2][3][4] The ability of this system to detect drug-induced body sway in healthy volunteers needs to be assessed. The AccuSway PLUS system works by analysing input from strain gauges under a force platform.…”

Aim:To assess the AccuSway PLUS system, which aims to quantify deficiency in human balance, using the measurement of the effect of lorazepam on body sway in healthy volunteers. Methods: A double-blind, randomised, placebo-controlled, two-way crossover study in 12 healthy male and female volunteers. Participants received a single oral dose of lorazepam 2mg and placebo, 1 week apart. Body sway was assessed using the AccuSway PLUS system, by measuring the length of the path of the centre-of-pressure (COP), and the area of the 95% confidence ellipse enclosing the COP (A95). Body sway was assessed at baseline and at 2, 3, 4, 6, 12, 18 and 24 hours after administration, in two positions: with the participants' eyes open and feet apart at hip's width (EOFA), and with their eyes shut and feet together (ESFT). Results: Statistically significant differences in body sway between lorazepam and placebo were detected for up to 18 hours after administration. The largest change in body sway was 2 hours post-dose, in the EOFA position; the mean (95% confidence interval) difference between lorazepam and placebo in fold change of A95 was 7.67 (3.88, 15.17), and in length of COP was 1.61 (1.23, 2.10). Conclusion: The findings confirm that the AccuSway PLUS system is a useful tool for detecting changes in body sway induced by centrally acting drugs.
