We got the beat

This open access article piqued my interest. I have long been aware of studies that showed that infants are basically altruistic. This is the first one I came across that shows that infant “Spontaneous Motor Tempo”  (SMT)  is something that can be measured. Here’s the link:

Infant Spontaneous Motor Tempo

From the abstract:

We present the first data documenting the SMT of infants from 5 to 37 months of age using a simple drumming task. As in late childhood and adulthood, we predicted that infant SMT would slow across the first years of life. However, we find that older infants drum more quickly than younger infants. Furthermore, studies of adults suggest larger bodies prefer slower rhythms. 

(emphasis added to quote)  … which explains why this is the first time I’ve heard about infant SMT. A couple of their research highlights:

  • SMT can be measured at 5 months old using a simple drumming task
  • Infant drumming gets faster and more regular as they get older

Kinda makes you want to read  the whole article…

or sing along to the title to this post:

We Got The Beat

Slow down… or speed up, that is the question…

This article isn’t about Parkinson’s, but since bradykinesia is one of the signature symptoms of parkinsonism, and the title is about the challenge of being slow, it interested me.

Birgitta Burger & Clemens Wöllner (2021): The challenge of being slow: Effects of tempo, laterality, and experience on dance movement consistency, Journal of Motor Behavior, DOI: 10.1080/00222895.2021.1896469

Basically, the authors found that people who were musically trained were better able to perform the given tasks consistently on both sides of their bodies. In other words, they are bilateral in terms of brain dominance, while other folks showed lower scores in terms of consistently performing the actions at different tempi (speeds). Because they were dominant on one or the other side of their brains. 

As an amateur musician, mostly untrained (or it didn’t take) I have found that during rhythm & drumming classes that I have been in that things like a simple paradiddle are much more difficult at a slower tempo than at a faster tempo. On the other hand, some combinations are more difficult at a faster tempo than at the slower tempo. Just trying to build those cross brain connections, as the prefrontal cortex to the back of the brain and the motor control and reward system parts fade out. So I will play at the piano at a slow speed, ’cause if I pick up the tempo my fingers get even more clumsier than they are.

Maybe difficulty with moving both sides consistently is part of the reason People with Parkinson’s have difficulty with balance and with falls?  From my own experience, can’t confirm or deny the hypothesis, since I’m not that good as a musician, but seem to have some bilateral skills, and until recently, when immersion in the moment took over the judgement and reason, have not experienced problems with balance or falls. Would be an interesting research question, though…

Research on the arts and outcomes related to Parkinson’s – and more related research and hypotheses

For our first article, we have a review on group based dance, singing, music, and theatrical treatments on a variety show of outcomes. 

A systematic review of active group-based dance, singing, music therapy and theatrical interventions for quality of life, functional communication, speech, motor function and cognitive status in people with Parkinson’s disease

Basically, they found that the arts seemed to have positive effects for folks with PD – but that not all types of arts were evaluated against all of the outcomes listed. So “More research is needed” to look into all aspects. But it’s a good thing.

Next up is a review of the effects of oxytocin and the effects of music on the human brain. And on social behavior and bonding. While not specifically directed at Parkinson’s disease, it is certainly applicable to treatments for people with Parkinson’s.

Links Between the Neurobiology of Oxytocin and Human Musicality

 It is argued that many of these characteristics of oxytocin biology closely mirror the diverse effects that music has on human cognition and emotion, providing a link to the important role music has played throughout human evolutionary history and helping to explain why music remains a special prosocial human asset. Finally, it is suggested that there is a potential synergy in combining oxytocin- and music-based strategies to improve general health and aid in the treatment of various neurological dysfunctions.

Keywords: oxytocin, music, dance, reward, empathy, trust, therapy

If there is a link between neurobiology and music, then it stands to reason that music played a part in the evolution of modern Homo sapiens. That is the topic of the brief review of:

Music and the Meeting of Human Minds by Alan Harvey

The author addresses

  1. when and why  modern humans evolved musical behaviors,
  2. the evolutionary relationship between music and language, and 
  3. why humans, perhaps unique among all living species, universally
    continue to possess two complementary but distinct communication streams.

He argues that “early in our history, the unique socializing and harmonizing power of music acted as an essential counterweight to the new and evolving sense of self, to an emerging sense of individuality and mortality that was linked to the development of an advanced cognitive capacity and articulate language capability.”

Dopamine is one of the keywords, so it should be of interest to People with Parkinson’s.

Another article along similar lines is Music as a coevolved system for social bonding,  The authors put forth an hypothesis and

make testable predictions for future research, including neurobiological bases of musicality and relationships between human music, language, animal song, and other domains. The music and social bonding (MSB) hypothesis provides the most comprehensive theory to date of the biological and cultural evolution of music.

I got rhythm, I got music…

Put together a slide presentation trying to synthesize some of the research on Parkinson’s Disease (PD) and the possibility of music, singing, playing musical instruments, and dance as means to counteract the progressive effects of dopaminergic neurons lost in the course of PD. Due to the length of the presentation and the limits of my computer resources, the narration seems to have gotten a little out of sync towards the end. But it is what it is, as they say: (note: added a PDF file of the presentation on 6-9-19 to make it easier to download and view)

Almost let these references get away

Some recent articles about music and dance – thought I had already published this – it appears not. Either that, or I’m more cognitively impaired than I thought I was. If this keeps up, I’ll have normal intelligence:

Dopamine, Oxytocin, Serotonin, and Endorphins 

Acronym is DOSE, and it’s a short article talking about how dance is good for you because it releases several different hormones and neurotransmitters – and not just because it makes you feel good – but because it does….😎

Language of music and psychophysical foundations  

from the abstract: “Application of music in rehabilitation medicine requires an understanding of the mechanisms of music perception. This article discusses differences in character of the basic melodic elements and addresses some of the specifics of tonal space. Colloquially, music is called the language of emotion. Bearing in mind that high-level cognitive functioning in humans is inseparable from affective consciousness, investigating the mechanisms of emotional processing belongs to an important area of cognitive sciences. Studying music perception can help to advance methods of music therapy and to elucidate major aspects of human consciousness.(emphasis added)(Article is on ReseaechGate; membership(.

Drumming program to improve social interactions

Although the article is about subjects with autism spectrum disorder (ASD), I think that the results are likely to be replicable with or generalizable to Parkinson’s Disease folks.

results suggest that the children with ASD significantly improved in the domains of enjoyment and fun, and showed a positive trend for developing improved social relationships with peers and camp counselor partners.

Something not really research related: An article in the St. Paul – Minneapolis ParkBugle about a Women’s Drumming Center. But for anyone dealing with stress, the quotes from teachers and students speak volumes about the power of community and rhythms.  People with Parkinson’s could do worse than follow this lead. ( I happen to have a warm-up protocol for a Parkinson’s music group I was in that begins with beating a drum and progresses to call and responses rhythms, much like this group).

Over at University of Michigan’s blog, Victor Kartch reports on anecdotal and scientific evidence on the uses of music as medicine in his January 11, 2017, Health Yourself column. He does list some references, as well as listing some of the conditions for which music has been used as therapy with positive results. Slight quibble: music therapy is used here in a very broad and loosely defined sense, which does not bother me, but might be viewed negatively by professionals in the business of music therapy, where a stricter definition of music therapy as a specific prescription for a specific symptom or condition might be considered the norm.

The Journal of the American Medical Association (JAMA) has an article titled “Move your arm like a swan” reporting on Dance for PD  and the “demedicalization” (my spell checker doesn’t think that’s a word) of Parkinson’s. The full article is free and there is also a link to download a copy of the article in PDF.  A related article on a Google Glass app that uses augmented reality is also linked to, is available for free, and has a link to download the full article in PDF. It’s like Christmas in January!
