Answer

A systematic review of clinical trials of speech and language therapy in Parkinson disease identified 3 randomized controlled trials that included 61 patients. The authors concluded that although improvements were noted, they were not able to conclusively confirm or refute the benefit of speech and language therapy in Parkinson disease due to the small number of patients in these trials, methodologic limitations, and possible publication bias.
