Abstract

Authors and colleagues have continued various activity and research of music therapy in Shikoku Island division of Integrative Medicine Japan (IMJ) for years. There are scientific methods for studying music therapy, in which near-infrared spectroscopy (NIRS) has been used for monitoring tissue oxygenation.It would be important to consider the method for not only the quantitative and qualitative research axes, but also the impressions for the music and art from each subject. Among them, Mixed Method Research (MMR) has been applied so far. We expect that further research in various perspectives will be developed in the future.

Text

Music therapy has been developing in each country across the world. There is World Music Therapy Association (WMTA) as an international organization.1 On the other hand, Dr. Shigeaki Hinohara, the father of music therapy in Japan, had developed music therapy for long years in Japan.2 The author held the 9th National Congress of the Japan Music Therapy Association (JMTA) in 2009, with 5,800 participants for three days.3 After that, the author has been a director of Shikoku Island Division, Integrative Medicine Japan (IMJ), and continued various activities for the development of music therapy and integrative medicine (IM).4

Authors and colleagues have continued various research for music therapy. They included the assessment of actual situation of ADL/QOL, assessment of the efficacy, egogram, Profile of Mental Status (POMS), related matters of EBM and NBM, and so on.3 It is certain that significant changes in numerical values and comparable indices are considered to be effective. However, we cannot know whether the client feels satisfied or effective with the therapy.4 In other words, the crucial point is that it is not numerical change, but a meaningful change.

It is known that music has a positive effect on maintaining and improving people's health. Depending on the atmosphere of the music, it affects how people can be feeling, which is related to “The Iso Principle”.5 Furthermore, there are some gaps in the mechanism of how our body works for music, and some music effects on our body and soul leading to improved health.6

In the clinical setting, most widely application of music therapy has been group music session for the elderly. From the research of combined physical exercise and music, there weremore effects on cognitive function in elderly people than exercise alone.7 Investigation of mechanism on music effects and well-controlled research program are necessary.8 In such cases, we have given some rhythm-based interventions and observed the changes in symptomatic benefits to the patients with various neurological diseases.8

There are scientific methods for studying music therapy. The application of near-infrared spectroscopy (NIRS) has been used for monitoring tissue oxygenation in clinical situations. NIRS has been developed for detecting various signals from cerebral hemodynamic changes.9 Thus, NIRS has been the focus for the various investigation presenting the change in the blood stream.10 Historically speaking, NIRS was originally used for the monitoring in the cerebral and myocardial oxygenation.11 It is non-invasive neuroimaging tool with several advantages such as low price, real time monitoring, portability, safety and simplicity.12 NIRS has been applied to clinical research including cerebral vascular accident (CVA), muscle metabolism, post-operative stroke, hemodynamic oxygenation changes of brain, and so on.13 Detail investigation of NIRS has been progressing at present.14

By the study of listening music on frontal lobe activation by NIRS, calm music could reduce human stress and bring effective relaxation.15 Furthermore, clapping the rhythm could increase brain activation. Consequently, active music session can become more effective than passive music session from brain activation.15 In the case of the research for giving verbal task, blood flow on NIRSsignals were also increased.16 Thus, the study of NIRS has been useful for measuring changes in blood flows for stimuli of music and language.

 Using NIRS, there was a study for how the brain modulates when musicians performed improvisation in a blues rock format.17 As a result, the activity in medical frontal lobe was found, which was associated with reduced activity of the dorsolateral prefrontal cortex (DLPFC). Although participants showed wide range of improvisation skills, significant correlation was found between subjective positive feelings for improvisation and the modulation of left DLPFC.17

Patients with major depressive disorder (MDD) were investigated using NIRS.18 The purpose was to explore the efficacy of music therapy on the activity of the brain. The verbal fluency task (VFT) was improved significantly after music therapy. Subjects of MDD showed more significantly elevated activation for the dorsolateral prefrontal cortex (DLPFC), orbitofrontal cortex (OFC) and ventromedial prefrontal cortex (VMPFC) after music therapy.18

There are some studies of music therapy for attention function in adults and elderly, but such studies in children have been rare with brain-imaging research.19 Similar to music, attention skills have developed in childhood with various engagement of the environment. Consequently, if these developments were interrupted, higher social, motor and cognitive functions may be influenced.19

Preterm infants tend to have cognitive and neurobehavioral impairments.20 Such neurodevelopmental problems may be relieved by non-pharmacological interventions including creative music therapy (CMT). It provides individual social and biological contact and musical stimulation by interactive, resource-/needs-oriented approaches.20

 There has been various development of the research method of music therapy.21 As one of the therapies, music has been studied for the perspectives of neuroscience. Recent topics include the aspects of executive function (EF) and attentional processes (AP). Some potential for EF/AP stimulation and neurorehabilitation would be involved in the playing the instruments and musical improvisation.21

For long years, human has loved arts in a variety manner. They are roughly classified into some categories as follows:

  1. Visual group (drawing, painting, sculpture, photography),
  2. Auditory and performance group (music, play, dance),
  3. Text-based group (poetry, novel).22

As arts developed more, the trials of research have progressed.23 From the research point of view, the biomarkers need to be quantitative values or qualitative factors. It is indeed that study for arts has scientific scale, but the feeling of each person cannot be excluded. In the region of various arts, we have to take evaluation into consideration that cannot be measured so easily.24

Consequently, the trial of strategy with mixed methods research (MMR) has been proposed.24 In the case of research practices, the combination of MMR and arts will lead to methodological pluralism. Such way of research direction can be expected to bring evaluation from various aspects and beneficial contribution from bio-psycho-social aspects.25

In summary, music therapy has a beneficial effect on people's minds and bodies, and research in this field has been progressing. It would be important to consider the method for not only the quantitative and qualitative research axes, but also the impressions for the music and art from each subject. Among them, Mixed Method Research (MMR) has been applied so far. We expect that further research in various perspectives will be developed in the future.
