| Outline of Final Research Achievements |
The effectiveness of manipulative therapy in the medical field depends on the subjective evaluation of the therapist and the patient. However, there is no evidence-based objective evaluation method for manipulative therapy. This study used a combined optical measurement of cortical activity and peripheral muscle blood flow to simultaneously evaluate changes in the prefrontal activity and the blood flow of the muscle subjected to manipulative therapy. The measurement was carried out with healthy participants with simulated muscle pain under the straight leg raising test. The manual therapy reduced the subjective pain, which was associated with reduced prefrontal activity and increased blood flow of the target muscle. This result is a major step to develop a system that can objectively evaluate the physiological effects of manipulative therapy.

| Academic Significance and Societal Importance of the Research Achievements |
徒手的な治療法である手技療法の効果を脳活動や筋血流から評価するためのシステムを開発した．近赤外分光法を用いて疼痛誘発時の脳活動を計測し，手技療法による疼痛感の緩和に伴って脳活動が減少することを示した．また被験筋の筋血流変化を拡散相関分光法により計測することに成功し，手技療法の筋血流増加効果を示すことができた．これらの結果は術者と患者の主観的な評価に委ねられている手技療法の効果を客観的に評価できる可能性を示すものであり，臨床や教育現場での活用が期待される．
