A growing body of research attests that that music therapy is more than a nice perk. It can improve medical outcomes and quality of life in a variety of ways. Here’s a sampling:
Improves invasive procedures. In controlled clinical trials of people having colonoscopies, cardiac angiography, and knee surgery, those who listened to music before their procedure had reduced anxiety and a reduced need for sedatives. Those who listened to music in the operating room reported less discomfort during their procedure. Hearing music in the recovery room lowered the use of opioid painkillers.
Restores lost speech. Music therapy can help people who are recovering from a stroke or traumatic brain injury that has damaged the left-brain region responsible for speech. Because singing ability originates in the right side of the brain, people can work around the injury to the left side of their brain by first singing their thoughts and then gradually dropping the melody. Former U.S. Representative Gabby Giffords used this technique to enable her to testify before a Congressional committee two years after a gunshot wound to her brain destroyed her ability to speak.
Reduces side effects of cancer therapy. Listening to music reduces anxiety associated with chemotherapy and radiotherapy. It can also quell nausea and vomiting for patients receiving chemotherapy.
Aids pain relief. Music therapy has been tested in patients ranging from those with intense acute pain to those with chronic pain from arthritis. Overall, music therapy decreases pain perception, reduces the amount of pain medication needed, helps relieve depression, and gives people a sense of better control over their pain.
Improves quality of life for dementia patients. Because the ability to engage with music remains intact late into the disease process, music therapy can help to recall memories, reduce agitation, assist communication, and improve physical coordination.
