本研究旨在探讨负重弓步测试（WBLT）背屈活动度与星星漂移平衡测试（SEBT）三个方向标准化前伸距离之间的关系。35名健康成人（14名男性，21名女性，年龄：25.9 +/-16.7岁，身高：166.7 +/-22.9 cm，体重：76.7 +/-22.8 kg）参与。所有受试者在SEBT的前、后内侧和后外侧方向上对每侧肢体进行三次最大下肢伸展试验，以评估动态平衡。受试者进行了三次WBLT试验，以测量最大背屈运动范围。因变量包括前、后内侧和后外侧方向的SEBT标准化到达距离的平均值和WBLT的平均值。仅SEBT的前向（平均值：79.0 ± 5.8%）与WBLT（平均值：11.9 ± 2.7 cm）显著相关，r = 0.53（p = 0.001）。该简单线性回归的r（2）为0.28，表明WBLT解释了前部标准化到达距离的28%的方差。WBLT解释了前伸距离内显著比例的方差，表明SEBT的该方向可能是评估背屈活动范围限制对动态平衡影响的良好临床试验。(C)2010年澳大利亚运动医学。由爱思唯尔有限公司出版。保留所有权利。
The purpose of this study was to examine the relationships between dorsiflexion range of motion on the weight-bearing lunge test (WBLT) and normalized reach distance in three directions on the Star Excursion Balance Test (SEBT). Thirty-five healthy adults (14 males, 21 females, age: 25.9 +/- 1 6.7 years, height: 166.7 +/- 22.9 cm, weight: 76.7 +/- 22.8 kg) participated. All subjects performed three trials of maximum lower extremity reach in the anterior, posteromedial, and posterolateral directions of the SEBT on each limb to assess dynamic balance. Subjects performed three trials of the WBLT to measure maximum dorsiflexion range of motion. Dependent variables included the means of the SEBT normalized reach distances in the anterior, posteromedial, and posterolateral directions and the mean of the WBLT. Only the anterior direction (mean: 79.0 +/- 5.8%) of the SEBT was significantly related to the WBLT (mean: 11.9 +/- 2.7 cm), r = 0.53 (p = 0.001). The r(2) for this simple linear regression was 0.28, indicating that the WBLT explained 28% of the variance in the anterior normalized reach distance. The WBLT explained a significant proportion of the variance within the anterior reach distance signifying this direction of the SEBT may be a good clinical test to assess the effects of dorsiflexion range of motion restrictions on dynamic balance.
