Biomechanical measurements to characterize the oral phase of dysphagia

Several biomechanical parameters that characterize the oral musculature are identified and techniques for quantifying these parameters in normal and dysphagic patients are discussed. These parameters include lip closure pressure, lip interface shear force, tongue thrust, and swallow pressure. Signif...

Description
Summary:Several biomechanical parameters that characterize the oral musculature are identified and techniques for quantifying these parameters in normal and dysphagic patients are discussed. These parameters include lip closure pressure, lip interface shear force, tongue thrust, and swallow pressure. Significant differences were found in each of these parameters measured in normal and dysphagic patients. The quantitative measurements can aid the physician in choosing the appropriate therapy during the course of rehabilitation of stroke and head injured patients.< >
