Table 3. Medial Branch Stimulation.
Means and standard errors (in parentheses) of muscle contractile properties within each age group and stimulation treatment group during protrusive actions of the tongue elicited by bilateral stimulation of the medial branch of the hypoglossal nerve (following section of the lateral branch).
