After I took a look at this uncontinued research I believed science community's ignoring this important research could be contributed to this research itself being problematic at three points: 1.Too small sample [2.No](https://2.No) long-term follow-up investigations after methods were done to PWS. 3.Too expensive. I didn't finish it with my most concentrations because the problems exposed by this method were too obvious and I know it did not deserve my careful reading. Also, science community never stopped researching into stuttering. With all due respect it seems to me it's you that are not following the process of researching. For example, [https://www.scientificamerican.com/podcast/episode/science-finally-has-a-good-idea-about-why-we-stutter/](https://www.scientificamerican.com/podcast/episode/science-finally-has-a-good-idea-about-why-we-stutter/) You should take a look at this research, and after reading this I am truly convinced the cure for stuttering is not far away, not to mention before neuroscience was established most of researches about stuttering were proven wrong so that's why researches about stuttering seem 'stagnated' along the history.
