Fig. 3 Comparison of PP, PTI, and CT measures. Bars represent Paromed pressure sensor recordings from 50 consecutive steps (mean ± SD) collected every 2 hours during an 8-hour wearing trial in a healthy, sensate subject. Mean and SD of measures across all time periods are noted on graphs for each sensor location. Note the similarity of measures across time for each sensor location. Walking velocities for each trial were as follows: 86.0, 83.9, 86.0, 84.6, and 86.0m/min for 0, 2, 4, 6, and 8 hours, respectively.
