[Purpose] We investigated whether blood flow-restricted training known as KAATSU training, was effective for rehabilitation of a pianist with residual neurological symptoms in the upper limbs. [Participant and Methods] A pianist with residual neurological symptoms in the upper body played "Revolutionary Etude" under two conditions: piano performance with (Piano-blood flow-restricted) and without (Piano-control) the restriction of blood flow to the upper limbs. In the Piano-blood flow-restricted exercise, a pressure of 130-170 mmHg was applied around the most proximal portion of both arms. The changes in upper limb circumference and muscle strength were measured before, immediately after, and 15 min after the performance. The impression of the piano performance was recorded after the Piano-blood flow-restricted exercise. [Results] Immediately after the piano performance, the forearm and upper arm circumferences had increased significantly in both arms, and the change was greater in the Piano-blood flow-restricted than in the Piano-control condition. The handgrip strength for the right arm also showed greater changes in the former than the latter. However, there were no significant differences between the two conditions regarding the handgrip strength of the left arm. [Conclusion] There is a high possibility that blood flow-restricted training is effective for rehabilitation of the pianist with residual neurological symptoms in the upper limbs.
[目的]我们研究了被称为KAATSU训练的血流限制训练，对一名上肢存在残留神经症状的钢琴家的康复是否有效。[参与者与方法]一名上肢存在残留神经症状的钢琴家在两种条件下弹奏《革命练习曲》：上肢血流受限（钢琴-血流限制组）和上肢血流不受限（钢琴-对照组）。在钢琴-血流限制训练中，在双臂最近端周围施加130 - 170 mmHg的压力。在弹奏前、弹奏后即刻以及弹奏后15分钟测量上肢周长和肌肉力量的变化。在钢琴-血流限制训练后记录对钢琴演奏的印象。[结果]钢琴演奏后即刻，双臂的前臂和上臂周长均显著增加，且钢琴-血流限制组的变化大于钢琴-对照组。右臂的握力在前者中也比后者有更大变化。然而，在左臂握力方面，两种条件之间没有显著差异。[结论]血流限制训练极有可能对上肢存在残留神经症状的钢琴家的康复有效。
