Fig. 3. Average EMG activity (thick line) across all 486 falling trials with +/– 1 standard deviation (thin line). A EMG sampling rate was 3,000 Hz and average fall time between fall initiation and hip impact was 979 ms (about 1 second). To superimpose and average, the EMG data were resampled with a rate of 3,000 Hz using a Matlab function “resample”. EMG, electromyography.
