About

To investigate whether an extended version of Valedo®Motion (termed Sensoro for brand management purposes), has the same trunk sway measures similar normal reference values of SwayStar. Offline data analysis of data obtained from Sensoro will be compared to data obtained by SwayStar, a highly accurate and widely accepted system for measuring balance control.

Full description

1. Determine a long time recording (over 60s) description of any differences in the drift and noise for the 2 systems during simultaneous recordings with the systems aligned with each other at rest.
2. Compare Sensoro trunk sway measures with those of SwayStar for a battery of 17 stance and gait tasks. The tasks to range from tasks with small velocities (standing on 2 legs eyes open, ca 0.1 deg/s or eyes closed on foam ca.10 deg/s) through tandem and gait tasks with velocities of ca 70 deg/s to the most dynamic with high velocities (rising from a chair, ca 150 deg/sec).
3. Estimate the additional value of adding trunk sway values for the yaw axis as an outcome measure of balance control.
4. Estimate the advantage of adding one or two sensors on the legs to help identify gait balance events and body posture.
