【目的】「非進行性の失語症に対するわが国の言語聴覚療法はどのようなアウトカムをもたらすか」を研究疑問（research question：以下，RQ）としてシステマティックレビューを実施した．
【方法】RQを基に適格基準を設け，医中誌Web，医書.jp，PubMedおよびハンドサーチにより文献を検索し，1次・2次スクリーニングを実施した．採択された研究について質的評価を実施した．
【結果】採択研究は24件で，非ランダム化比較試験10件，症例対照研究2件，単一事例研究7件，ケースシリーズ5件であった．内容は言語機能訓練22件，実用コミュニケーション訓練2件であり，言語機能訓練が大半を占めた．前者は言語機能，後者はコミュニケーション能力において回復を認め，一部は談話などに般化した．
【考察】非進行性の失語症に対して言語機能訓練および実用コミュニケーション訓練が実施されており，言語機能とコミュニケーション能力の回復と一部の般化が確認された．今後，機能・活動・参加を視野に入れたエビデンスレベルの高い研究の蓄積が望まれる．
Purpose：A systematic review was performed to compile evidence on the outcomes of speech-language-hearing therapy for non-progressive aphasia in Japan.
Method：Eligibility criteria were established based on the research question, and literature was collected using Ichushi-Web, Isho-jp, PubMed, and hand searching. After a primary and secondary screening, a qualitative evaluation was conducted on the accepted studies.
Results：A total of 24 studies were accepted, including 10 nonrandomized controlled trials, 4 case-control studies, 7 single case studies, and 5 case series. Of these, 22 of the studies, which was by far the majority of them, involved language therapy while only 2 studies involved functional communication training. The former showed recovery in language function and the latter in communicative competence, with some generalization to discourse.
Discussion：Language therapy and functional communication training were conducted for non-progressive aphasia, and recovery of language function and communication ability and partial generalization were confirmed. In the future, it is hoped that the amount of high-level evidence-based research looking at function, activity, and participation will increase.
