Figure 3

Average stimulation charge threshold for bilateral nerve-cuff electrodes. Thresholds were measured three times, averages and standard deviations were calculated, and a one-way ANOVA was performed. Brackets and asterisks (*) denote statistically significant differences (p<0.05). Stimulation charge threshold decreased for left nerve-cuff contacts 1 and 2 and stayed constant or fluctuated but returned to original values for all other contacts over 63 weeks after nerve-cuff implantation. Note that week 6 data were unavailable for left contact 4, and right contacts 2 and 4. Also, data from weeks 6 and 16 for left nerve-cuff contact 2 were significantly different from all other data points for that electrode, but some brackets were omitted from the figure for clarity.
