Brief Summary:

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.

Group/Cohort Intervention/treatment
Screened and recruited from the Division of Neurorehabilitation, Department of Clinical Neurosciences, University Hospital and University of Geneva, Geneva, Switzerland by a senior consultant neurologist (BL). Patients were included if they were hospitalized for stroke rehabilitation, were able to undergo psychophysical testing and presented with a facial impairment according to the House-Brackmann criteria ≥2 15. They were excluded if they presented with acute pain in the oro-facial sphere (nominal question) or an additional neuro-muscular disease.
Other: observation
Similar to stroke group in regard to age, gender and dental state. no stroke
Other: observation

Primary Outcome Measures :
  1. Tactile detection threshold (0.25 - 512 mN) of mechanoreceptors of oral mucosa and lips as assessed with monofilaments of pre-defined thicknesses [ Time Frame: maximum 2 weeks post-stroke ]
