There is a need for a validated rapid procedure for the evaluation of posture, defined as lateral balance/imbalance at the pelvic, shoulder, and neck levels. This would enable clinicians to determine the importance of symmetry in the pathophysiology of musculoskeletal disorders and to assess the efficacy of devices and treatments claiming to normalize or improve posture. In this investigation, the efficacy of such a device, a set of insoles with a hypothesized proprioceptive-like action, was evaluated through use of the described procedure.
To develop a new scoring system to evaluate body posture on the basis of symmetry and to use this scoring system to investigate the efficacy of insoles containing a combination of mineral derivatives designed to balance posture through a neurophysiological effect.
The posture score was based on the evaluation of 4 postural parameters: pelvic and shoulder lateral balance/imbalance, static shoulder rotation, and amplitude of head rotation. In the placebo-controlled study, 32 patients were tested in a double-blind fashion, either with placebo insoles or with insoles containing mineral derivatives. The same study was repeated in unblind conditions in 137 patients selected from 2 chiropractic clinics in an open-label protocol.
A crossover placebo-controlled, double-blind study and a multicenter, large-scale, open-label study in patients selected from chiropractic clinics.
A basal postural evaluation in 137 patients revealed that no patient had a perfect symmetry-ie, a perfectly or nearly perfectly balanced posture. The insoles with mineral derivatives induced a highly significant and similar improvement in the postural score in both the crossover double-blind study (32 patients; 56.7% improvement) and the open-label study (137 patients; 60.7% improvement, P < 0.001).
All patients tested and selected in chiropractic clinics exhibited asymmetries and postural imbalances according to the newly developed scoring method, and this method was successful in assessing the efficacy of insoles exerting a profound and immediate postural effect through a hypothesized neurophysiological mode of action.
需要一种经过验证的快速程序来评估姿势，姿势定义为骨盆、肩部和颈部水平的侧向平衡/失衡。这将使临床医生能够确定对称性在肌肉骨骼疾病病理生理学中的重要性，并评估声称能使姿势正常化或改善姿势的设备和治疗方法的疗效。在本研究中，通过使用所描述的程序评估了一种具有假设的本体感觉样作用的鞋垫装置的疗效。
开发一种基于对称性评估身体姿势的新评分系统，并使用该评分系统研究含有矿物质衍生物组合的鞋垫通过神经生理效应平衡姿势的疗效。
姿势评分基于对4个姿势参数的评估：骨盆和肩部侧向平衡/失衡、静态肩部旋转以及头部旋转幅度。在安慰剂对照研究中，32名患者以双盲方式进行测试，分别使用安慰剂鞋垫或含有矿物质衍生物的鞋垫。在开放标签方案中，从2家整脊诊所选取137名患者，在非盲条件下重复相同研究。
一项交叉安慰剂对照双盲研究以及一项在整脊诊所选取患者的多中心、大规模开放标签研究。
对137名患者的基础姿势评估显示，没有患者具有完美的对称性，即姿势完全或几乎完全平衡。在交叉双盲研究（32名患者；改善56.7%）和开放标签研究（137名患者；改善60.7%，P<0.001）中，含有矿物质衍生物的鞋垫均使姿势评分有高度显著且相似的改善。
根据新开发的评分方法，在整脊诊所测试和选取的所有患者均表现出不对称和姿势失衡，并且该方法成功评估了通过假设的神经生理作用模式对姿势产生深刻且即时影响的鞋垫的疗效。
