OBJECTIVE
The goal of this effort to investigate if experienced breachers, professionals with a career history of exposure to repeated low-level blasts, exhibited postural instability.
METHODS
Postural data were examined using traditional tests of means and compared to normative data.
RESULTS
Breachers had significantly lower NeuroCom Sensory Organization Test (SOT) visual scores (within normative limits), prolonged Limits of Stability (LOS) test reaction time (30% of breachers and 7% of controls testing abnormal), and slower LOS movement velocity (21% of breachers and 0% of controls testing abnormal) compared to controls.
CONCLUSION
Our LOS test findings are like those previously reported for students in the military breacher training course and seem to indicate that while acute effects of blasts on sensory control of balance fade away, effects on postural LOS persist over time.
目的
本研究旨在调查经验丰富的爆破手（职业生涯中多次暴露于低水平爆炸的专业人员）是否表现出姿势不稳定。
方法
使用传统的均值测试方法检查姿势数据，并与标准数据进行比较。
结果
与对照组相比，爆破手的神经康感觉组织测试（SOT）视觉评分明显较低（在正常范围内），限制稳定性（LOS）测试反应时间延长（30%的爆破手和 7%的对照组测试异常），以及 LOS 运动速度较慢（21%的爆破手和 0%的对照组测试异常）。
结论
我们的 LOS 测试结果与之前在军事爆破手训练课程中对学生的研究结果相似，似乎表明尽管爆炸对平衡感觉控制的急性影响消失，但对姿势 LOS 的影响会随着时间的推移而持续存在。
