Fig 5. Power spectra examples of non-faller and faller with frequencies up to 100Hz for different signals used in this study to extract features: The three TUGs (segmented signal); only the regular TUG (segmented TUG); only the dual task manual TUG (segmented TUG-M); and only the dual task cognitive TUG (segmented TUG-C).

The amplitudes are in a logarithmic scale.
