Haptic information, provided by a non-rigid tool (i.e., an "Anchor system"), can
reduce body sway in individuals who perform a standing postural task. However, it
was not known whether or not continuous use of the anchor system would improve
postural control after its removal. Additionally, it was unclear as to whether or
not frequency of use of the anchor system is related to improved control in older
adults. The present study evaluated the effect of the prolonged use of the anchor
system on postural control in healthy older individuals, at different frequencies
of use, while they performed a postural control task (semi-tandem position).
Participants were divided into three groups according to the frequency of the
anchor system's use (0%, 50%, and 100%). Pre-practice phase (without anchor) was
followed by a practice phase (they used the anchor system at the predefined
frequency), and a post-practice phase (immediate and late-without anchor). All
three groups showed a persistent effect 15min after the end of the practice phase
(immediate post-practice phase). However, only the 50% group showed a persistent
effect in the late post-practice phase (24h after finishing the practice phase).
Older adults can improve their postural control by practicing the standing
postural task, and use of the anchor system limited to half of their practice
time can provide additional improvement in their postural control.
