Final answer:
The unidisciplinary team model has vertical communication with the leader in control.
Step-by-step explanation:
In the context of rehabilitation team models, the model in which communication is more vertical than lateral, with the leader controlling team conferences, is the unidisciplinary team.
In a unidisciplinary team, the leader holds most of the decision-making power and directs the team members in a top-down manner.
In contrast, multidisciplinary teams, interdisciplinary teams, and transdisciplinary teams promote more lateral communication and collaboration among team members.
