BENEFITS 益处
Improves spinal rotation mobility; improves shoulder and lateral hip mobility; improves posture; enhances core control during trunk rotation.
改善脊椎旋转的活动度；改善肩膀与外侧髋的活动度；改善姿态；提高躯干旋转时的核心控制能力。
TARGET MUSCLES 目标肌群
Internal/external obliques (primary rotators), multifidus and rotatores (spinal rotation), transversus abdominis (deep stabilizer), shoulder girdle stabilizers.
腹内斜肌、腹外斜肌（主导旋转）、多裂肌与回旋肌（脊椎旋转）、腹横肌（深层稳定）、肩带稳定肌群。
SETUP 设置
None. May place small soft pillow under head for support and cervical alignment.
无。头下可放置小软垫以支撑头部，改善颈椎排列。
CUES 口令
Starting position: Side-lying, legs bent together. Arms extended forward at 90° shoulder flexion, hands together or overlapped. Head on bottom arm or pillow. Breathing/Movement: Inhale, widen between scapulae. Exhale, top hand reaches toward ceiling, leading eyes, sternum, ribs, spine in segmental rotation, keeping pelvis/legs still. Feel thoracic twist at end. Inhale, feel arms reaching long. Exhale, initiate from ribs, trunk returns segmentally to start. May switch breath. Imagery: Trunk like a slowly opening book, spine as axis, ribcage (cover) and pelvis (back cover) separating gracefully.
起始位：侧卧，双腿屈膝并拢。双臂在肩关节屈曲90度位置向远处延伸，双手合十或重叠。头枕在下方手臂或软垫上。 呼吸与动作：吸气，肩胛骨中间放宽。吐气，上方的手向天花板方向延伸，带动眼睛、胸骨、肋骨与脊椎逐节旋转，尽量保持骨盆和腿不动。在旋转末端感受胸椎的扭转。吸气，感受手臂向两端延伸。吐气，从肋骨开始启动，带动躯干逐节回转到起始位。可交换呼吸模式。 想象提示：想象躯干像一本慢慢打开的书，书脊（脊椎）是转动的轴，封面（胸廓）和封底（骨盆）优雅地分离。
IMAGERY 意象
Direct: Feel thoracic spine turning segmentally like gears. Indirect: Like a thick book, pages (ribs) opening one by one. Space: Imagine space inside ribcage gently widening during rotation. Feeling: Focus on contraction of opposite oblique and the backward opening reach of top scapula.
直接：感受胸椎如齿轮般逐节转动。间接：像一本厚重的书，书页（肋骨）一页一页地打开。空间：想象胸腔内的空间在旋转时被温柔地拓宽。感觉：注意力放在对侧腹斜肌的收缩感和上方肩胛骨向后打开的延伸感上。
TACTILE CUES 触觉提示
1. Lightly place hand on top acromion, guide to reach toward ceiling. 2. Lightly touch ribs on rotation side, guide segmental rotation. 3. Lightly place hand on hip, cue to stay stable.
1. 一手轻放在练习者上方肩峰，引导其向天花板延伸。2. 一手轻触其旋转方向的肋骨，引导逐节转动。3. 一手轻放在其髋部，提示其保持稳定不动。
PROGRESSION 进阶
1. Straighten top leg during rotation to increase lever. 2. Circle arm around body to increase range and coordination challenge.
1. 在伸展时伸直上面的腿，增加下肢力臂。2. 手臂围着身体绕圈，增加动作幅度和协调性挑战。
REGRESSION 退阶
1. Place pillow behind body to limit range. 2. Bottom arm fully supports head. 3. For limited shoulder mobility, place pillow under moving shoulder, or bend elbow and place hand on sternum.
1. 转动时在身体后方加枕头以限制活动范围。2. 下方手枕在头下提供更多支撑。3. 肩关节活动受限者，可将活动侧肩膀下方加枕垫，或手肘弯曲手放在胸骨上。
COMMON ERRORS 常见错误
Moving only arm without trunk rotation; compensating with cervical extension; trunk and hip rocking/rotating, losing stability; pushing shoulder forward instead of opening.
只动手臂而躯干不参与转动；颈椎伸展后仰代偿；躯干和髋部跟着晃动旋转，失去稳定性；肩膀向前推而非打开。
PRECAUTIONS 注意事项
Modify arm position for limited shoulder mobility. For spinal stenosis, may keep lumbar in slight flexion within tolerance. For disc conditions, limit range. For osteoporosis, avoid end-range rotation.
肩关节活动受限者需调整手臂位置。脊椎狭窄症者可在可接受范围内，将腰椎做延伸屈曲的姿势。椎间盘病症者限制活动范围。骨质疏松症者避免脊椎旋转到最大的活动范围。
