Orofacial impairment following stroke frequently involves a reduced chewing performance and dysphagia. This study investigated the sensitivity of oral tissues following stroke and its potential impact on chewing efficiency. The following two Null-hypotheses (H0) were tested: i. Post-stroke patients do not show a reduced intra-oral sensitivity compared to a healthy controls. ii. Intra-oral sensitivity is not correlated to chewing efficiency.
