Outline of Final Research Achievements

This study was an exercise therapy intervention using rhythmic auditory stimulation in patients with type 2 diabetes mellitus with diabetic peripheral neuropathy. The intervention period was one week, and the rhythmic auditory stimulation group performed walking with sound stimulation at -10% of their own comfortable speed tempo using an electronic metronome.
Comparison of pre- and post-intervention results showed that the control group had a significant increase in maximum plantar pressure at the heel after the intervention. On the other hand, the sound-stimulated group showed a significant decrease in maximum plantar pressure at the big toe and heel after the intervention. A comparison of the amount of change between the two groups before and after the intervention showed that the rhythmic auditory stimulation group showed significantly lower maximum plantar pressures at the big toe and heel compared to the control group.

Academic Significance and Societal Importance of the Research Achievements

糖尿病性末梢神経障害合併2型糖尿病（DPN）患者は歩行中の足底面が床面と接触する際に生じる圧力（足圧）の上昇によって足潰瘍が生じ、足切断やADLの低下を来す。本研究の成果により自己快適歩行速度の－10%のテンポにした音刺激を用いた歩行運動を行うことにより、母趾と踵の最大足底圧を有意に低下させる結果は、DPN患者の下肢切断予防につながる可能性があり社会的に意義がある。また、現在までに足潰瘍予防として効果の示されている靴療法や装具療法とは異なる介入方法となり得るため学術的意義があると考えられる。
