Hypothesis
During 2D perturbations, variations in the center of pressure (CoP) would be increased primarily at frequencies coinciding with the roll and pitch platform perturbation frequencies.
Conclusion
The study found that during continuous 2D balance perturbations, changes in postural sway were primarily at the frequencies of the roll and pitch perturbations, and responses to each 1D component were similar to those measured during individual 1D tasks.
Supporting Evidence
- Postural responses were primarily in the mediolateral direction at the frequencies of the roll perturbation.
- Postural responses were primarily in the anteroposterior direction at the frequencies of the pitch perturbation.
- The sway responses during 2D conditions were similar to those generated during separate administration of the individual 1D components.
Takeaway
This study created a new test to see how well people can keep their balance when pushed in different directions, and it showed that people can respond well to these pushes.
Methodology
The study developed a balance perturbation test using two independent sinusoidal signals to create 2D balance disturbances and measured postural sway in healthy adults.
Limitations
The study's findings may not generalize to individuals with vestibular impairments as only healthy adults were tested.
Participant Demographics
Healthy adults, average age 37 years, with no history of neurological or vestibular disorders.
