1972: Dr. Larson: Rehabilitation for Dysphagia (earliest description of a bedside)
1983: Logamen’s book was published
1986: First issue of “Dysphagia” journal was published

1992: 1st DRS (society for dysphagia)
2001: diagnosis and swallowing disorders becomes part of SLP scope of practice (it was still not a required course)
2004: ASHA required at least 1 dysphagia course
2007: 1st ASHA held survey of SLPs (60% adult, 40% infant, toddler, children) w/high % working with swallowing

Answer 4

Question 5

Aging and Swallowing (12):

Answer 5

1) Aging is accompanied by many subtle changes in swallowing function. In otherwise healthy subjects over 80 (90) years, the following changes are observed:
2) Tongue muscle atrophy, which leads to reduced lingual propulsion
3) Hardening of flexible cartilages and age-related ossification
4) Sagging of the larynx (laryngoptosis/presbylaryngeus)
5) Transit times are increased (delayed)
6) Residue increased
7) UES opening reduced
8) Timing of swallow response/start delayed (though not beyond norm for pharyngeal timing of 1 second)
9) Frequent penetration into the airway but it is never beyond the vocal folds (aspiration is never normal)
10) Reduced sensations
11) Reduced cough reflex
12) Piecemeal deglutition

**Aspiration is never due to normal aging!!
