Modulation of Force below 1 Hz: Age-Associated Differences and the Effect of Magnified Visual Feedback
Figure 6
Modulation of power below 1 Hz for young and older adults with magnification of visual feedback.
The top row shows a representative force output low-passed at 1 Hz for a young and an older adult during the lowest (0.05°) and highest (1.5°) visual angle. The bottom row demonstrates the power spectrum of force from 0–1 Hz for the same subjects. Age-associated differences in the modulation of force oscillations below 1 Hz are evident.
