Physiological Factors Related to Aspiration Risk: A Systematic Review
Dysphagia
Steele, C. M., & Cichero, J. A. (2014).
Dysphagia, 29(3), 295-304.
This two-stage review first identifies measures and parameters that correlate aspiration or risk of aspiration with dysphagia, and second, examines specific physiological factors associated with aspiration, in order to identify what clinical measures can be used to identify individuals who are at risk for aspiration.

The findings suggest a number of features are associated with impaired swallowing. The results support the assessment of the following as measurements of aspiration or risk of aspiration: tongue pressure strength, hyoid bone movement, amount of time bolus remains in pharynx, and respiratory rate and respiratory pattern during swallow.
