Important towards progress in stuttering recovery? None. It's absolute garbage through and through. It's easy to tell these people don't sit down to think before deriving a hypothesis. Clock in, clock out. If you're going to study, say, structural brain alternations, you must come up with some idea of how you will make the information work for you. What might have led to it, how it might be tapped into as we know the brain is plastic, anything but the usual cop out. Imagine a group of researchers conducting such study to arrive at: "These findings strengthen the potential significance of brain structures in persistent stuttering." 🤣🤣🤣
