Figure 6.
Scatterplot demonstrating the association between participants’ sham swallowing rate and their swallowing rate during 70 and 110 Hz stimulation. Pearson’s product-moment correlation demonstrated a strong association between the two (r(26)=.89, p<.001). Markers located above the dotted reference line indicated an increase in swallowing with vibration compared to sham for that participant; markers located on or below the reference line, indicated equal or reduced swallowing during vibration compared to sham.
