Blood Flow Restriction Training Applied With High-Intensity Exercise Does Not Improve Quadriceps Muscle Function After Anterior Cruciate Ligament Reconstruction: A Randomized Controlled Trial.

この研究はインパクトが大きい可能性があると判断されました。 OEのAIによるハイインパクト指標は、論文が掲載されたジャーナルと論文自体の科学的内容の両方からのシグナルを統合することで、論文の影響力を推定します。 最先端の自然言語処理を用いて開発されたOEハイインパクトモデルは、ジャーナルのインパクトファクターのみよりも、研究の将来の引用実績をより正確に予測します。 これにより、臨床的に意義のある研究をより早く認識することができ、読者は将来の診療を形成する可能性が最も高い論文に焦点を当てることができます。

研究概要

Thirty-eight patients undergoing rehabilitation following anterior cruciate ligament reconstruction surgery were randomized to receive 8 weeks of eccentric or concentric quadriceps exercise training, with or without blood flow restriction during exercise, after the completion of a standardized 10 week post-operative protocol. The primary outcome of interest was the change from baseline in isometric and isokinetic quadriceps muscle strength. Secondary outcomes of interest included the change in rectus femoris muscle volume and central activation ratio. Outcomes were assessed after completion of the exercise program, and again upon patient return to activity. Results revealed no significant differences between all four groups in the change from baseline in all outcomes, at all time-points. Similarly, when analyzing those who received blood flow restriction compared to those who did not receive blood flow restriction, no significant differences in all outcomes were observed.
