<div>All three trials reported that individuals with Parkinson's disease demonstrated improvements in speech after receiving speech with speech and language intervention compared to no treatment or placebo control. Although the outcomes reported across trials varied greatly, many outcomes revealed clinically significant changes after therapy. However, the authors caution making firm conclusions due to the limited number of studies, limited number of participants (n = 63), and methodological flaws. Further research is warranted.</div>
