SMR/Theta神經回饋訓練對大腦感覺動作皮質區SMR、Theta皮質活化效果之探討

Abstract

本研究主要目的為探討SMR/Theta神經回饋比值訓練對於大腦感覺動作皮質區（SMR）以及Theta皮質之活化效果。過去研究顯示，利用SMR/Theta神經回饋比值以促進運動表現有正面顯著效果。然而，真正促使其提升的導因是否為透過該訓練，從而使參與者透過改變自身腦波活動進而影響具體行為，目前還尚未明瞭；此外，SMR/Theta神經回饋比值訓練是源自於增加SMR或者是降低Theta，目前也未有研究指出明確解釋。有鑑於此，本研究招募20位專業高爾夫選手，將20位選手進行隨機分派，分為神經回饋組與偽回饋組。該分組透過前測、10次SMR/Theta神經回饋以及後測，檢定神經回饋對於推桿表現、心理主觀感受、SMR/Theta相對功率比值、SMR與Theta在前後測之間的改變。此次研究結果發現此二組前測腦波數值與進球率無差異，而經由10次SMR/Theta神經回饋後，神經回饋組於推桿表現、心理主觀感受、以及腦波數值皆高於偽回饋組；且SMR/theta神經回饋效果主要來自於增加SMR，而非降低Theta。因此，推論高爾夫選手經過 10次 SMR/theta神經回饋比值訓練，增加SMR這個途徑來優化推桿表現。Previous study suggested that SMR/theta neurofeedback training (NFT) can improve sports performance. However, how the NFT translate its effect on increasing SMR or decreasing Theta has not been investigated. Therefore, the purpose of this study was to investigate the effects of SMR/theta neurofeedback training on the cortical activity of sensorimotor rhythm and theta. The present study recruited 20 expert golfers and assigned them into the pseudo-training group and NFT group. Both groups underwent pre-test, 10 session SMR/theta NFT, and post-test. Results showed that the SMR/theta neurofeedback training resulted in an increase of SMR instead of an decrease of Theta. This finding indicated that the optimization of putting performance can be completed by the increase of SMR after 10 sessions of SMR/theta neurofeedback training.
