Based on findings by Atsuko Miyazaki, a researcher at the RIKEN Center for Computational Engineering, it has been found that cognitive functions may be improved simply by enjoying the experience of playing drums, especially for those with dementia. Various programs have been introduced to improve dementia, but many are complicated as compared to playing drums, which is a simple rhythmic striking exercise.
The survey was conducted by randomly selecting 46 residents from special nursing homes for the elderly. They were then divided into two groups: 27 were part of a drum performance program intervention group and the remaining 19 were part of the control group. The intervention group was asked to play drums with an instructor three times a week for 30 minutes and for 12 weeks. On the other hands, the control group was asked to spend their day as usual. Drums were investigated as an opportunity to enjoy rhythm freely, emphasizing improvisation rather than playing.
As a result of the survey, the MMSE index (out of 30 points), which indicates the cognitive function of 22 intervention groups excluding those with a participation rate of less than 60%, increased by 2.05 points, and FAB (out of 18 points) increased by 2.36 points. On the other hand, it was found that the control group had a decrease of MMSE of 3.24 points and FAB of 0.35 points.
At the same time, this survey also investigated upper limb motor function (range of motion), BMI and skeletal muscle mass index (SMI). Although there was no changes in body weight or BMI, some improvements in upper limb motor function was observed.
Until now, playing musical instruments such as drums have been said to be highly effective in preventing dementia, but it seems that it can be expected to be more effective as a program for improving cognitive function and upper limb motor function for patients with dementia. It is also suitable for people with severe dementia because it has the ability to maintain rhythmic response exercise even if dementia worsens and the program becomes incomprehensible.
