Figure 3

Comparison of vibration detection thresholds in all elderly subjects, for two frequencies of vibration at several body sites. The histograms show the mean and standard error of vibration detection thresholds of all elderly subjects – subjects aged under 65 (open columns), subjects aged between 65 and 74 (hatched columns) and subjects aged over 75 (filled columns) at each site tested, for two frequencies of vibration (30 Hz – upper panel, 200 Hz – lower panel). The y-axis represents the peak to peak amplitude of vibration detection thresholds (dB re: 1 μm peak-to-peak).
