答：可以把骨盆比作桌面，双腿是桌腿。长短腿会让骨盆向短腿一侧倾斜，脊柱为维持身体平衡，会反向弯曲代偿，时间久了形成功能性（代偿性）脊柱侧弯。这类侧弯不是脊柱本身骨头长歪，是地基不平带来的继发弯曲，早期纠正下肢力线、骨盆水平后，脊柱有机会慢慢回正。单纯反复提醒孩子 “坐直”，解决不了地基的问题。
答：结构性长短腿（真短腿）：股骨、胫骨骨性长度本身不一样，多由先天发育、外伤骨折术后导致；仰卧、坐起测量，腿长差距基本不变。
答：居家简易筛查（仅初步参考，不能替代 X 光确诊）：仰卧伸直双腿，从后方对比脚踝高度；再保持双腿伸直坐起，再次对比。坐起后长短差距变小 / 消失，偏向功能性；差距不变，结构性可能性更高。
功能性长短腿，除鞋垫外，还要配合臀中肌、核心康复训练，稳定骨盆。
