The influence of an artificial leg length discrepancy on lateral pelvic tilt and on activity of the intrinsic lumbar back muscles was investigated. An artificial leg length discrepancy of up to 50 mm was created by putting boards of different height under the right foot. Lateral pelvic tilt increased linearly with increasing artificial leg length discrepancies. The rectified and averaged e.m.g. of the intrinsic lumbar back muscles showed a small increase at the longer leg side. It increased non-linearly with an increment in slope above a certain artificial leg length discrepancy (mean 34 mm).
研究了人工腿长差异对骨盆侧倾和腰椎固有肌活动的影响。通过在右脚下方放置不同高度的木板来制造高达50毫米的人工腿长差异。骨盆侧倾随着人工腿长差异的增加而呈线性增加。腰椎固有肌的整流平均肌电图在长腿侧有小幅增加。在超过一定的人工腿长差异（平均34毫米）时，其增加呈非线性，斜率增大。
