The swaymeter measures displacements of the body at the waist level whereas the ataxiameter can be used to defin e sway as an angular movement of the body around the ankle jo int. Lords sway meter is a simple instrumentation to measure postural sway. The acceleration and the angular velocity of body sway are valuable variables to assess the body sway and they are measured by attaching the accelerometer or the gyroscope sensor to the a part of the body 8 10 14 15. Body s way can be measured with a simple technology such as u sing a swaymeter 8 or wright s ataxiameter 9. It was found that sway was not present in all. Height also influences body sway in that as height increases functional reach typically decreases.
In this study postural sway in standing was analyzed with sway meter. Of your measurement set up. When the body sway module opens the existing measurements of the selected subject inside the current visit are displayed and the user can review them see section analysis for details. The measurement on the right of the line will be your sway bar size. You can printout our free sway bar measuring tool here. Tests have shown that older adults demonstrate shorter functional reach and larger body sway path lengths.
Many studies used a pendulum model or an inverted pendulum as com above its pivot point 16 17. Once you print out the tool take a pair of scissors and cut out the tool. Wrap the tool around the bar and match the starting line with the size line. If no measurements have yet been done for this subject than only the option to start a new measurement is enabled. However this test is only a measure of anterior and posterior sway.
