[Purpose] The purpose of this study was to examine the acute effects of five minutes of plantar flexor static stretching (PSS) on the balance and gait of the elderly. [Subjects and Methods] Twenty-five subjects aged 65 years and above performed 5 min of PSS in the form of wedge board standing. The sway length of each subject's center of mass was measured to examine the subject's static balance. It was measured by one minute of quiet standing with the eyes closed. Functional reach tests (FRTs), timed up and go tests (TUGs), and 10-meter walk tests (10MWTs) were performed to examine dynamic balance and gait before and after PSS. [Results] The outcome showed significant increases in sway distances (6.55 ± 5.03 cm) after stretching. However, in the FRTs, TUGs, and 10MWTs, the reach distance and time did not show any significant changes. [Conclusion] These results suggest that the elderly subjects temporarily experienced difficulties in maintaining balance immediately after the PSS but that their dynamic balance and gait were not adversely affected after a short period of time. Therefore, to prevent falls and perform exercises in a safe way, it is recommended to allow patients to rest after performing PSS.
[目的] 本研究旨在探讨五分钟足底屈肌静态拉伸（PSS）对老年人平衡能力和步态的急性影响。[对象与方法] 25名65岁及以上的受试者以楔形板站立的形式进行了5分钟的PSS。测量每个受试者重心的摆动长度以检查受试者的静态平衡。通过闭眼安静站立一分钟来进行测量。在PSS前后进行功能性伸展测试（FRT）、计时起立行走测试（TUG）和10米步行测试（10MWT），以检查动态平衡和步态。[结果] 结果显示拉伸后摆动距离显著增加（6.55±5.03厘米）。然而，在FRT、TUG和10MWT中，伸展距离和时间没有显示出任何显著变化。[结论] 这些结果表明，老年受试者在PSS后立即暂时难以维持平衡，但在短时间后他们的动态平衡和步态并未受到不利影响。因此，为防止跌倒并以安全的方式进行锻炼，建议患者在进行PSS后休息。
