姿势不稳是老年人普遍存在的问题，它与行动障碍、活动受限和害怕摔倒有关。姿势控制的评估有助于及早发现平衡缺陷，并帮助卫生专业人员处理这一问题，以防止老年人跌倒。这项研究的目的是找出在过去12个月内有跌倒和没有跌倒的老年人区分的压力值中心。参与者是170名老年人(平均年龄67岁，50名跌倒者和120名非跌倒者)。在3次30s睁眼单腿站立试验中，使用测力台评估了前、后和内侧方向的压力中心、面积和摇摆速度。采用跨试验均数进行分析。还评估了时间限制(参与者能够单腿站立多长时间，最多30秒)。跌倒者的姿势控制能力比非跌倒者差(效应大小≥为0.52P<；0.05)。确定的临界值为：压心区10.3 cm~2，前后方速度2.9 cm/S，内侧向速度3.4 cm/S。测力平台参数曲线下面积为0.72，灵敏度为78%，特异度为68%。没有跌倒的人和跌倒的人在时间限制变量上没有显著差异(17秒对18秒)。老年人单腿站立时的用力平台参数与跌倒病史相关。截断点的曲线下面积、灵敏度和特异度均可接受，其中压力区中心在区分跌倒与不跌倒方面表现最佳。
Postural instability is a common problem among older people, and it is associated with mobility impairments, activity limitation and fear of falling. The evaluation of postural control can contribute to the early detection of balance deficits and help health professionals to manage this problem to prevent falls in older adults. The aim of this study was to identify center of pressure cut-offs to differentiate between older adults with and without falls in the past 12 months. The participants were 170 older adults (mean age 67 years, 50 fallers and 120 non-fallers). Center of pressure area and sway velocity in the anterior-posterior and medio-lateral directions were assessed using a force platform during three 30s one-legged stance trials with eyes open. The mean across trials was used for analysis. The time-limit (how long the participant was able to stay in one-legged stance, up to 30s) was also assessed. Fallers had poorer postural control than non-fallers (effect size ≥ 0.52, P <0.05). The cut-offs identified were 10.3 cm2 for Center of pressure area, 2.9 cm/s for velocity in the anterior-posterior, and 3.4 cm/s for medio-lateral velocity. The force platform parameters obtained an area under the curve of 0.72, with sensitivity of 78% and specificity of 68%. There were no significant differences between non-fallers and fallers for time-limit variable (17 seconds vs. 18 seconds). Force platform parameters during one-legged stance were associated with history of falls in older adults. The cut-offs obtained acceptable area under curve, sensitivity and specificity, with center of pressure area presenting the best performance to differentiate between fallers and non-fallers.
