Video: Singing Reduces Stress, Improves Motor Function In Parkinson’s Disease

Houston, Texas, USA : Singing may provide benefits beyond improving respiratory and swallow control in people with Parkinson’s disease, according to new data from Iowa State University researchers.

The results from the pilot study revealed improvements in mood and motor symptoms, as well as reduced physiological indicators of stress. Elizabeth Stegemöller, an assistant professor of kinesiology, cautions this is preliminary data, but says the improvements among singing participants are similar to benefits of taking medication. She presented the work at the Society for Neuroscience 2018 conference.

“We see the improvement every week when they leave singing group. It’s almost like they have a little pep in their step. We know they’re feeling better and their mood is elevated,” Stegemöller said. “Some of the symptoms that are improving, such as finger tapping and the gait, don’t always readily respond to medication, but with singing they’re improving.”

Stegemöller, Elizabeth “Birdie” Shirtcliff, an associate professor in human development family studies; and Andrew Zaman, a graduate student in kinesiology, measured heart rate, blood pressure and cortisol levels for 17 participants in a therapeutic singing group. Participants also reported feelings of sadness, anxiety, happiness and anger. Data was collected prior to and following a one-hour singing session.

This is one of the first studies to look at how singing affects heart rate, blood pressure and cortisol in people with Parkinson’s disease. All three levels were reduced, but Stegemöller says with the preliminary data the measures did not reach statistical significance. There were no significant differences in happiness or anger after class. However, participants were less anxious and sad.

Why does singing work?

The results are encouraging, but researchers still have a big question to tackle: what is the mechanism leading to these behavioral changes? They are now analyzing blood samples to measure levels of oxytocin (a hormone related to bonding), changes in inflammation (an indicator of the progression of the disease) and neuroplasticity (the ability of the brain to compensate for injury or disease) to determine if these factors can explain the benefits of singing.

“Part of the reason cortisol is going down could be because the singing participants feel positive and less stress in the act of singing with others in the group. This suggests we can look at the bonding hormone, oxytocin,” Shirtcliff said. “We’re also looking at heart rate and heart rate variability, which can tell us how calm and physiologically relaxed the individual is after singing.”

The research builds upon the team’s previous findings that singing is an effective treatment to improve respiratory control and the muscles used for swallowing in people with Parkinson’s disease. The prevalence of Parkinson’s disease is expected to double over the next 20 years. ISU researchers say therapeutic singing has the potential to provide an accessible and affordable treatment option to improve motor symptoms, stress and quality of life for people with Parkinson’s disease.

A second study found that singing may be good medicine for Parkinson’s patients.

Singing? To benefit people with Parkinson’s disease? It just may help, a researcher says.

“We’re not trying to make them better singers, but to help them strengthen the muscles that control swallowing and respiratory function,” said Elizabeth Stegemoller, an assistant professor of kinesiology at Iowa State University.

Stegemoller holds a weekly singing therapy class for Parkinson’s disease patients. At each session, participants go through a series of vocal exercises and songs.

Singing uses the same muscles as swallowing and breathing control, two functions affected by Parkinson’s disease. Singing significantly improves this muscle activity, according to Stegemoller’s research.

“We work on proper breath support, posture and how we use the muscles involved with the vocal cords, which requires them to intricately coordinate good, strong muscle activity,” she said in a university news release.

Other benefits noted by patients, their families and caregivers include improvements in mood, stress and depression, Stegemoller said.

Her research was published in Complementary Therapies in Medicine.

Parkinson’s disease is a chronic and progressive movement disorder. Nearly one million Americans live with the disease. The cause isn’t known, and there is no cure at present. But there are treatment options such as medication and surgery to manage symptoms, according to the Parkinson’s Disease Foundation.

Symptoms can include tremors of the hands, arms, legs, jaw and face; slowness of movement; limb rigidity; and problems with balance and coordination.

  1. I was diagnosed 2 years ago at age 63. Symptoms were tremor in right leg, loss of handwriting ability, and soft voice. I also have difficulty rising from a seated position and have balance issues. I started out taking only Azilect, then Mirapex, and 6 months ago Sinemet. Several months ago I started falling frequently, hence the reason for Sinemet. I tried every shots available but nothing worked. In June 2018, my neurologist and I decided to go with natural treatment and was introduced to Natural Herbal Gardens natural organic Parkinson’s Herbal formula, i had a total decline of symptoms with this treatment, the Tremor, falling frequently, stiffness, body weakness, balance issues, depression and others has subsided. Visit Natural Herbal Gardens official website ww w. naturalherbalgardens. com. This treatment is a breakthrough for all suffering from Parkinson’s, don’t give up Hope. Keep Sharing the Awareness, herbs are truly gift from God.
