Abstract：
Limits of stability is required to perform functional activities and other advanced tasks of life without losing balance, and assessment of limits of stability is essential in clinical practice. Forward, Lateral, and Oblique direction reach tests are clinical balance tests that assess limits of stability, and these reach distances in various directions may be symmetrical or asymmetrical. The aim was to establish the symmetry between various reach distances on three reach tests and to establish the concurrent validity of oblique, forward, and lateral direction reach test distances with limits of stability measured by the Iso Free machine of TecnoBody company.
METHODS: The measurements of oblique, forward, and lateral reach tests and limits of stability excursions of center of pressure were taken in eight directions on Iso Free machine of Techno Body in fifty typical college-going young adults who were recruited through convenience sampling. Pearson correlation test was used to find the relationship between forward, lateral, and oblique direction reaches and limits of stability in forward, lateral, and oblique directions. Regression analysis was used to find the factors influencing the forward, lateral, and oblique reach tests.
RESULTS: The reach distances were symmetrical, and out of the three tests, the lateral and oblique direction reach tests have a moderate positive correlation with limits of stability test in lateral and oblique directions with an r-value of 0.569 (p < 0.001) and 0.50 (p < 0.001) respectively. A Significant standardized beta value of 0.49 (p < 0.05) for the oblique direction reach test with total stability limits.
CONCLUSIONS: The oblique and lateral direction reach tests are correlated with their respective center of pressure excursion. However, the oblique direction reach test moderately correlated with the total limits of stability scores. Forward reach distances were more in number followed by oblique and lateral reach distances among young Saudi adults.

摘要：
在不失去平衡的情况下执行功能活动和其他高级生活任务需要稳定性极限，和稳定性极限的评估在临床实践中是必不可少的。向前,横向,和倾斜方向达到测试是临床平衡测试，评估稳定性的限制，并且这些在各个方向上的到达距离可以是对称的或不对称的。目的是在三个到达测试中建立各种到达距离之间的对称性，并建立倾斜的并发有效性，forward,和横向方向达到测试距离与由TecnoBody公司的IsoFree机器测量的稳定性极限。
方法：倾斜的测量，forward,在通过便利抽样招募的50名典型的上大学的年轻人中，在TechnoBody的IsoFree机器上的八个方向上进行了横向延伸测试和压力中心稳定性偏移的极限。采用皮尔逊相关检验来寻找远期与远期之间的关系，横向,倾斜方向到达和向前稳定的极限，横向,和倾斜的方向。回归分析用于寻找影响远期的因素，横向,和斜伸测试。
结果：到达距离是对称的，在三个测试中，横向和倾斜方向的到达测试与横向和倾斜方向的稳定性测试极限呈中度正相关，r值分别为0.569（p<0.001）和0.50（p<0.001）。倾斜方向的显著标准化β值0.49(p<0.05)达到总稳定性极限。
结论：倾斜和横向触达测试与它们各自的压力偏移中心相关。然而,倾斜方向达到测试与稳定性分数的总极限适度相关。在年轻的沙特成年人中，向前延伸的距离更多，其次是倾斜和横向延伸的距离。
