PPA Sway Path

Sway path has been identified as one of the most useful summary measures of postural sway.

In studies conducted by researchers at NeuRA, sway path has been found to be the best measure of postural sway for predicting falls in older people and other clinical groups at risk of falls.

This app automatically records and stores sway path as well as maximal anterior-posterior and lateral sway as measured by the PPA sway meter developed by Prof Stephen Lord. In doing so this app greatly enhances the usability and application of this low-tech sway measurement device.

Use of this app requires a PPA sway meter. To purchase a PPA sway meter please contact us at [email protected].
