This study aimed at developing lumbar repositioning and seated equilibration tests.
3D-electrogoniometric study of trunk repositioning and equilibration in seated position.
Postural equilibrium and lumbar proprioception alterations have been shown in patients with low-back pain.
In 21 healthy volunteers, pure flexion and flexion+rotation repositioning error was measured using 3D-electrogoniometry. Lumbar kinematics was analysed (time and frequency domain) during antero-posterior and lateral equilibration tests in seated position. Reproducibility and stability of the protocol were evaluated.
Reproducibility and stability were good. Pure flexion repositioning error was similar to previous reports. For flexion+rotation tests, repositioning error was 3 degrees for flexion and 1 degrees for rotation. Amplitude, imbalance time and power spectrum were significantly larger in lateral than in antero-posterior equilibration tests.
The feasibility of kinematic analysis of lumbar repositioning and equilibration was shown. Repositioning error values were in agreement with previous studies. New tests and parameters were proposed. Lateral equilibration tests appeared more demanding than antero-posterior tests.
In patients with low-back pain, lumbar repositioning and equilibration tests may be of use to define rehabilitation strategies and to evaluate treatment outcome.
本研究旨在开发腰椎重新定位和坐位平衡测试。
对坐位时躯干重新定位和平衡进行三维电子测角研究。
下腰痛患者已出现姿势平衡和腰椎本体感觉改变。
对21名健康志愿者，使用三维电子测角法测量单纯屈曲和屈曲加旋转时的重新定位误差。在坐位的前后和侧向平衡测试期间分析腰椎运动学（时域和频域）。评估该方案的可重复性和稳定性。
可重复性和稳定性良好。单纯屈曲重新定位误差与先前报告相似。对于屈曲加旋转测试，屈曲时的重新定位误差为3度，旋转时为1度。侧向平衡测试中的幅度、失衡时间和功率谱显著大于前后平衡测试。
显示了腰椎重新定位和平衡运动学分析的可行性。重新定位误差值与先前研究一致。提出了新的测试和参数。侧向平衡测试似乎比前后测试要求更高。
在下腰痛患者中，腰椎重新定位和平衡测试可能有助于确定康复策略和评估治疗结果。
