The ability to maintain static and dynamic balance is a prerequisite for safe walking and for obtaining functional mobility. For this reason, a reliable and valid means of screening for risk of falls is needed. The functional reach test (FRT) is used in many countries, yet it does not provide some kinematic parameters such as shoulder or pelvic girdles translation. The purpose was to analyze video records measuring of distance, velocity, time length, arm direction and girdles translation while doing FRT.
A cross-sectional, descriptive study was conducted where the above variables were correlated to the mini-mental state examination (MMSE) for mental status and the Tinetti balance assessment test, which have been validated, in order to computerize the FRT (cFRT) for elderly patients with neurological disorders. Eighty patients were tested and 54 were eligible to serve as experimental group. The patients underwent the MMSE, the Tinetti test and the FRT. LAB view software was used to record the FRT performances and to process the videos. The control group consisted of 51 healthy subjects who had been previously tested.
The experimental group was not able to perform the tests as well as the healthy control subjects. The video camera provided valuable kinematic results such as bending down while performing the forward reach test.
Instead of manual measurement, we proposed to use a cheap with fair resolution web camera to accurately estimate the FRT. The kinematic parameters were correlated with Tinetti and MMSE scores. The performance values established in this study indicate that the cFRT is a reliable and valid assessment, which provides more accurate data than "manual" test about functional reach.
维持静态和动态平衡的能力是安全行走和获得功能性活动能力的先决条件。因此，需要一种可靠且有效的方法来筛查跌倒风险。功能伸展测试（FRT）在许多国家都有应用，但它并未提供一些运动学参数，如肩部或骨盆带的平移。目的是分析在进行功能伸展测试时测量距离、速度、时间长度、手臂方向和骨盆带平移的视频记录。
进行了一项横断面描述性研究，将上述变量与用于精神状态评估的简易精神状态检查表（MMSE）以及已得到验证的Tinetti平衡评估测试相关联，以便为患有神经系统疾病的老年患者实现功能伸展测试的计算机化（cFRT）。对80名患者进行了测试，其中54名符合条件作为实验组。患者接受了MMSE测试、Tinetti测试和功能伸展测试。使用LAB view软件记录功能伸展测试的表现并处理视频。对照组由51名先前接受过测试的健康受试者组成。
实验组在测试中的表现不如健康对照组。摄像机提供了有价值的运动学结果，例如在进行前伸测试时弯腰。
我们建议使用廉价且分辨率适中的网络摄像头来准确估计功能伸展测试，而不是进行手动测量。运动学参数与Tinetti和MMSE评分相关。本研究确定的表现值表明，计算机化功能伸展测试是一种可靠且有效的评估方法，它在功能伸展方面比“手动”测试提供更准确的数据。
