Outline of Final Research Achievements

After bone loss, bone mass was restored by applying low-intensity mechanical stress. It and the intensity parameters of electrical stimulation were the same. In the immobilized state, osteoclasts were activated and depressions were formed on the surface. However, electrical stimulation smoothed the bone surface. These results suggest that electrical stimulation from the "immobilized state to the weight-bearing phase" promotes recovery from bone loss.

Academic Significance and Societal Importance of the Research Achievements

近年では医業だけでなく、医業類似行為に対しても科学的根拠が求められている。しかし、業界としては症例報告がほとんどで、研究活動が定着しておらず、エビデンスに乏しいのが現状である。この２つの学問の融和（統合医療）を通して健康科学の発展に寄与する研究を提案する必要性が高まっており、本研究を立案するに至った。
