目的1/Narrative objectives1 |
複合性局所疼痛症候群(Complex Regional Pain Syndrome; CRPS)や幻肢痛は薬物療法にも抵抗性で有効な治療法がなく難治性疼痛と呼ばれる.
これらの治療法として行われているものの一つに鏡療法があり,鏡に健常肢を映しこみ,その動きを観察することで痛みが軽減することが報告されている.また,動きを観察することによる痛みの軽減は電動義手の操作でも報告されている.
動作の観察による痛みの軽減は,ある目的に沿った動作が主体的に行われたという感覚である運動主体感の発生が重要だと考える.運動主体感は入力と実際の動作に遅延が生じた時に曖昧になることが明らかにされている.
本研究では電動義手の外見を変化させることで運動主体感の発生の違いを,電動義手への入力と実際の動作に遅延を生じさせることで明らかにする. |
Complex Regional Pain Syndrome (CRPS) and Phantom Limb Pain (PLP), which are likely resistant to drug therapy and considered there are no effective treatments, are named intractable pain. Mirror visual feedback therapy has been done as the one of the treatments. In this therapy, it is reported that the pain levels of the patients with CRPS and PLP are alleviated due to observe the movement that reflected their own normal limbs on the mirror. The pain alleviation, when using prosthetic hand called Sauerbruch prosthesis that can be moved by user's intended, is also reported.
Based on these case, we consider that Sense of Agency (SA) is important to reduce the pain. SA is a feeling that motion in accordance with a certain purpose is occured on its own intention. It is founded SA could be ambiguous when there is a delay in input and actual operation.
In present study, we aim to clealify the occurence defference of SA by changing the appearances of the electric prosthetic hand and the delay time that is from input to acual motion of the one. |

介入1/Interventions/Control_1 |
健常者を対象とし,介入は最大2時間行う.全ての指が適切に設計された電動義手を操作する.また電動義手の遅延時間はランダムに提示し,遅延時間の違いで運動主体感がどれほど得られたかをアンケートによる評価を行う |
Intervention toward healthy people is made for up to two hours. In this group, the participants manipulate the electric prosthetic hand of which all fingers are properly designed. The input-action time of the electric prosthetic hand is set to delay randomly, and the questionnaire is used to evaluate SA difference in delay time. |
介入2/Interventions/Control_2 |
健常者を対象とし,介入は最大2時間行う.示指のみ適切に設計された電動義手を操作する.また電動義手の遅延時間はランダムに提示し,遅延時間の違いで運動主体感がどれほど得られたかをアンケートによる評価を行う |
Intervention toward healthy people is made for up to two hours. In this group, the participants manipulate the electric prosthetic hand of which only index finger is properly designed. The input-action time of the electric prosthetic hand is set to delay randomly, and the questionnaire is used to evaluate SA difference in delay time. |
介入3/Interventions/Control_3 |
健常者を対象とし,介入は最大2時間行う.示指のみ不適切に設計された電動義手を操作する.また電動義手の遅延時間はランダムに提示し,遅延時間の違いで運動主体感がどれほど得られたかをアンケートによる評価を行う |
Intervention toward healthy people is made for up to two hours. In this group, the participants manipulate the electric prosthetic hand of which only index finger is inadequately designed. The input-action time of the electric prosthetic hand is set to delay randomly, and the questionnaire is used to evaluate SA difference in delay time. |
介入4/Interventions/Control_4 |
