[The interaction between the parkinsonian patient and his caregiver during feeding: a theoretical model].

: A theoretical model for the assessment of the interaction between the patient with Parkinson's disease and his caregiver during assisted feeding is suggested. It is based on literature about impairments in Parkinson's disease and about interaction. The main concepts of the model are clarity of cues, sensitivity, interpretation, responsiveness and synchrony. It is suggested that the patient should be allowed to focus on the socioemotional content versus the task content of communication during different phases of interaction during the meal.
