歩行動作の左方向転換時に右側方への不安定性が生じていた脳血管障害左片麻痺の一症例

—右広背筋の筋活動に着目して—

A stroke patient with left hemiplegia was at risk of falling to the right side when turning left, due to, lack of displacement to the left side of the center of gravity which resulted in instability to the right side when turning. Therapy was administered for the left hip joint abductor muscle, left obliquus internus abdominis muscle, and obliquus externus abdominis muscle, but this did not improve turning movements. Therefore, therapy then focused on the alignment of the upper trunk, right shoulder joint, and the right latissimus dorsi muscle. As a result of the new therapy, the center of gravity shifted to the left side thereby reducing the risk of fall. It is our opinion that the right lateral bending of the upper trunk was caused by hypertonia of the right latissimus dorsi muscle, and that hypertonia of the right latissimus dorsi muscle had prevented the patient from shifting her center of gravity to the left side.
