Figure 4: (a) Scatter plot showing the relationship between functional reserve measures comparing maximum isometric pressure (MIP) to water swallowing pressures and tongue strength, as measured by MIP, with swallow pressures expressed as a percentage of MIP. (b) Scatter plot showing the relationship between functional reserve measures comparing maximum isometric pressure (MIP) to regular effort saliva swallowing pressures and tongue strength, as measured by MIP, with swallow pressures expressed as a percentage of MIP.
