This examination assesses lip competence, tongue movement, oral mucosa, dental state, mouth opening, speech, drooling, diet, appearance, oral sensation, and shoulder movement. Where appropriate, the physician will ask the patient questions regarding items on the questionnaire to ensure the completeness and accuracy of the outcome assessment.
