Final answer:
The most likely pattern of organization for the research project is a long-term, ongoing collaboration between the rehabilitation clinic and the neighboring university.
Step-by-step explanation:
The most likely pattern of organization for the research project described in the question is a long-term, ongoing collaboration between the rehabilitation clinic and the neighboring university. This is supported by the examples and information provided in the case studies. Long-term research projects with community partners involve establishing trusting relationships, regular return visits, and a focus on problem-solving and applying research to benefit the collaborating community. In this case, the collaboration has received a major grant for a five-year research project, but the continuance of the project after the five years is uncertain.
