Some doctors and therapists believe that wearing high-heeled shoes causes increased lumbar lordosis and that this may be a cause of low back pain. The purpose of this study was to evaluate whether high-heeled shoes increase lumbar lordosis and to do so with more reliable methods and a larger sample size than used in previous studies.
Fifty participants from a chiropractic university were included in a test group (32 female and 18 male) and 9 in a control group (3 female and 6 male). A Spinal Mouse was used to measure lumbar lordosis in test participants barefoot and then again with 3- or 4-in high-heeled shoes after a 10-minute adaptation period of walking and sitting and standing while wearing the shoes. Reliability of the testing conditions was evaluated with 9 barefoot control participants before and after an identical adaptation period, and intra- and interexaminer reliability of Spinal Mouse measurements was tested by use of a wooden model built to mimic the proportions of a human spine.
Both groups showed non-significant decreases in lordosis between the first and second scans (high heels: 23.4° to 22.8°, P = .17; control: 18.8° to 17.6°, P = .16). Scans of the wooden spine model were highly reliable (intra- and interexaminer intraclass correlation coefficients > .999).
Consistent with most previous studies, high-heeled shoes did not affect lumbar lordosis in most people while standing. Future research could investigate the effect of shoes during dynamic conditions or identify affected subgroups.
一些医生和治疗师认为，穿高跟鞋会导致腰椎前凸增加，这可能是腰痛的一个原因。本研究的目的是评估高跟鞋是否会增加腰椎前凸，并采用比以往研究更可靠的方法和更大的样本量来进行评估。
来自一所脊椎按摩疗法大学的50名参与者被纳入测试组（32名女性和18名男性），9名被纳入对照组（3名女性和6名男性）。使用脊柱测量仪在测试参与者赤脚时测量腰椎前凸，然后在穿着3英寸或4英寸高跟鞋行走、坐立10分钟适应期后再次测量。在相同的适应期前后，对9名赤脚的对照参与者进行测试条件的可靠性评估，并通过使用一个按照人体脊柱比例制作的木制模型来测试脊柱测量仪测量的内部和外部检查者可靠性。
两组在第一次和第二次扫描之间的前凸均有非显著性下降（高跟鞋组：从23.4°降至22.8°，P = 0.17；对照组：从18.8°降至17.6°，P = 0.16）。木制脊柱模型的扫描结果高度可靠（内部和外部检查者组内相关系数>0.999）。
与大多数先前的研究一致，高跟鞋在大多数人站立时不会影响腰椎前凸。未来的研究可以调查鞋子在动态条件下的影响，或确定受影响的亚组。
