According to Medical News Today, a recent pilot study found singing therapy might reduce some of the difficult-to-treat motor and mood symptoms associated with Parkinson's disease.
Recently, researchers from Iowa State University in Ames ran a pilot study to investigate the impact of singing on a small group of individuals with Parkinson's disease. Heart rate, blood pressure, and cortisol levels dropped across the board after sessions in this small sample. There was also a noted drop in levels of anxiety and sadness following the sessions and statistically significant improvements in some motor symptoms that are often unaffected by drugs. In particular, upper extremity bradykinesia (slowness of movement), tremor, and walking were most improved.
