Previous studies have found that increased intra-abdominal pressure helps to reduce spinal loading and improve spine stability. Non-extensible lumbar belts (NEBs) could elevate intra-abdominal pressure and augment spinal stability. NEBs have been used in the healthcare field to help reduce pain and improve spine function for people with low back pain. However, the effect of NEBs on static and dynamic postural stability is not clear.
This study aimed to investigate whether NEBs affect static and dynamic postural stability. Twenty-eight healthy male subjects were recruited to finish four static postural stability tasks and two dynamic postural stability tests. Center of pressure (COP) values during 30 s of quiet standing, dynamic postural stability index (DPSI) and Y balance test (YBT) score with and without NEBs were analyzed.
NEBs had no significant effect in all COP variables in the static postural tasks. The results of a repeated measure two-way ANOVA indicated the NEBs significantly improved the dynamic postural stability in YBT score and DPSI (F = 5.506, p = .027, [Formula: see text] and F = 83.94, p = .000, [Formula: see text] respectively).
The study results indicate that non-extensible belts improve dynamic stability in healthy male participants, with potential implications for rehabilitation and performance enhancement programs.
先前的研究发现，增加腹腔内压力有助于减轻脊柱负荷并提高脊柱稳定性。非弹性腰部束带（NEBs）可以升高腹腔内压力并增强脊柱稳定性。NEBs 已在医疗保健领域中用于帮助减轻腰痛患者的疼痛并改善脊柱功能。然而，NEBs 对静态和动态姿势稳定性的影响尚不清楚。
本研究旨在探讨 NEBs 是否会影响静态和动态姿势稳定性。招募了 28 名健康男性受试者完成四项静态姿势稳定性任务和两项动态姿势稳定性测试。分析了安静站立 30 秒时的中心压力（COP）值、动态姿势稳定性指数（DPSI）和使用和不使用 NEBs 时的 Y 平衡测试（YBT）得分的 COP 值。
NEBs 在所有静态姿势任务的 COP 变量中均无显著影响。重复测量两因素方差分析的结果表明，NEBs 显著改善了 YBT 得分和 DPSI 的动态姿势稳定性（F=5.506，p=0.027，[Formula: see text]和 F=83.94，p=0.000，[Formula: see text]）。
研究结果表明，非弹性腰带可提高健康男性参与者的动态稳定性，这对康复和性能增强计划具有潜在影响。
