Lower crossed syndrom
• Lower Crossed Syndrome (LCS), also known as pelvic crossed syndrome, is described as a muscle imbalance pattern that affects the lower kinetic chain which includes the lumbopelvic hip complex, knee, and ankle.

contra-directional lumbopelvic rhythm
• In contrast, during contra-directional lumbopelvic rhythm, the pelvis rotates in one direction while the lumbar spine simultaneously rotates in the opposite direction.

PELVIC-ON-FEMORAL OSTEOKINEMATICS
• Lumbopelvic Rhythm The lower, caudal end of the axial skeleton is firmly attached to the pelvis by way of the sacroiliac joints. As a consequence, rotation of the pelvis over the femoral heads typically changes the configuration of the lumbar spine. This important kinematic relationship is known as lumbopelvic rhythm.

下交叉综合征--LBP
• 髂腰肌、竖脊肌紧张 • 腹肌、臀肌力量减退 • 骨盆顺时针方向运动：
• LCS常发生于长时间伏案工作、姿势较差的人群。 • 以腰-盆肌肉系统的失平衡为显著特征。

• the pelvis and lumbar spine rotate in the same direction. This movement maximizes the angular displacement of the entire trunk relative to the lower extremities
下交叉综合征
• 顺时针方向运动：
– 骨盆前倾（anterior rotation） – 腰椎后伸（extension）
• 逆时针方向运动
– 骨盆后倾（posterior rotation） – 腰椎前屈（flexion）

腰-盆肌肉系统失衡
• 紧张而短缩的肌肉
– 髂腰肌 – 股直肌 – 竖脊肌 – 腰方肌 – 阔筋膜张肌（TFL） – 梨状肌
• 力量减退的肌肉
– 腹肌 – 臀大肌 – 臀中肌

下交叉综合征的表现
• 姿势
– 骨盆前倾（anterior tilt） – 腰椎后伸 – 髋关节屈曲外旋
• 骨盆与腰椎的运动方向一致，称之为同向 腰盆节律

• it is useful for activities such as extending the reaching capacity of the upper extremities.
• 同向腰盆节律，对于增加上肢的活动空间 有重要意义

腰盆节律
• 腰椎通过骶髂关节与骨盆连接，当骨盆与 髋关节发生运动时，骨盆位置的改变同样 会引起腰椎的运动，腰椎与骨盆在运动中 的节律性关系称为腰盆节律。

ipsi-directional lumbopelvic rhythm
• 腰椎与骨盆的运动方向相反，称为反向腰 盆节律
• 反向腰盆节律，对于维持上身的稳定直立 有重要意义

• 下交叉综合征（LCS），又称为骨盆交叉综合征，由肌肉 系统的失平衡而引起的骨盆及下肢的运动链受损而导致的 症候群，常常会累及下腰部、骨盆、髋、膝及踝关节。

• This syndrome can be found in individuals who sit for prolonged periods, continuously perform tasks for extending periods of time utilizing poor posture, or have been immobilized.
