Table 1 Simplified set of normative data for timing measures in reflex normal swallowing (oral final stage + pharyngeal stage + initial esophageal stage) [age range: duration range, sec]

From: Standardization of surface electromyography utilized to evaluate patients with dysphagia

Age groups (y)
Saliva swallow 18–70: 1.0–5.44   70+: 1.44–6.24
Normal swallow 18–70: 1.0–5.74   70+: 2.3–6.7
20 cc swallow 18–70: 1.8–6.2   70+: 1.8–8.13
One swallow while drinking 18–70: 0.56–2.56   70+: 0.55–3.0
100 cc drinking 18–60: 6.2–15.4 61–70: 5.4–21.4 70+: 7.1–28.3
# swallows while drinking 18–40: 4–9 41–70: 4–12 70+: 4–16
