Visual leg length insufficiency detection and correction is compared with established radiographic procedures on 41 consecutive patients presenting to a chiropractic clinic with low back pain. It is commonly accepted that the most accurate procedure of short leg demonstration is the standing X ray. Visual correction, as described by Rene Cailliet, uses three anatomical points of reference: a) iliac crest levelness, b) vertical appraisal of the spine from the sacral base (the spine should be perpendicular to the sacral base) and c) levelness of the posterosuperior iliac spine (PSIS) dimples. Lifts of varying thickness were placed under the foot of the short leg in both leg length corrective procedures. This study found that the visual method of measurement did not differ significantly from the X-ray method of measurement for leg length insufficiency. Further, it was found that when comparing those in which the visual measure was less than the X-ray measure and those in which the visual measure was greater, there was a significant relationship between visual and X-ray measures. Eta (eta 2) demonstrates that there is a very strong relationship between visual and X-ray methods of measurement. A review of the literature is presented regarding the correlation of leg length insufficiency and musculoskeletal disorders, as well as the discrepancy required to alter biomechanical properties of the trunk and lower extremity.
对41例因腰痛到整脊诊所就诊的连续患者，将视觉腿长不足检测及矫正方法与既定的放射学方法进行比较。人们普遍认为，展示短腿最准确的方法是站立位X线检查。如勒内·凯利（Rene Cailliet）所描述的视觉矫正方法，使用三个解剖学参考点：a）髂嵴水平度；b）从骶骨基部对脊柱进行垂直评估（脊柱应垂直于骶骨基部）；c）髂后上棘（PSIS）酒窝的水平度。在两种腿长矫正方法中，均在短腿一侧的脚下放置不同厚度的鞋垫。本研究发现，对于腿长不足，视觉测量方法与X线测量方法无显著差异。此外，研究发现，比较视觉测量值小于X线测量值的患者与视觉测量值大于X线测量值的患者时，视觉测量与X线测量之间存在显著相关性。埃塔（eta 2）表明，视觉测量方法与X线测量方法之间存在非常强的相关性。本文还对腿长不足与肌肉骨骼疾病的相关性，以及改变躯干和下肢生物力学特性所需的差异进行了文献综述。
