PDS is a geriatric affliction, described in 1999, characterized by postural impairments, including backward disequilibrium, freezing, a deterioration in the ability to anticipate postural adjustments, anxiety and fear of falling, inducing loss of autonomy. This study compared 10 subjects suffering from PDS, aged 87.3+/-4.9 years, with 10 control subjects, aged 85.4+/-7.9 years concerning postural control (body sway amplitude). In all participants, postural control was assessed using the SwayStar system in natural (spontaneous) and standardized stances, eyes open and eyes closed over a period of 40 s. It was found that: (1) with eyes open, subjects with PDS showed greater body sway amplitude than did controls whatever the position (natural or standardized) and the plane (sagittal or frontal) considered (F(1,16)=6.05; p=0.026), (2) with eyes closed, subjects with PDS showed greater body sway amplitude than did controls in the natural stance whatever the plane (F(1,18)=7.65; p=0.013). In conclusion, PDS has a negative effect on postural control. This data must be taken into account during the rehabilitation of patients with this syndrome.
PDS 是一种老年疾病，于 1999 年被描述，其特征为姿势障碍，包括向后失衡、冻结、预测姿势调整能力下降、焦虑和害怕跌倒，导致自主性丧失。本研究比较了 10 名患有 PDS 的受试者（年龄 87.3±4.9 岁）和 10 名对照受试者（年龄 85.4±7.9 岁）的姿势控制（身体摆动幅度）。在所有参与者中，使用 SwayStar 系统评估姿势控制，在自然（自发）和标准化姿势下，睁眼和闭眼 40 秒。结果发现：（1）睁眼时，无论考虑的位置（自然或标准化）和平面（矢状面或额状面）如何，PDS 受试者的身体摆动幅度均大于对照组（F(1,16)=6.05；p=0.026）；（2）闭眼时，无论平面如何（F(1,18)=7.65；p=0.013），PDS 受试者在自然姿势下的身体摆动幅度均大于对照组。总之，PDS 对姿势控制有负面影响。在对患有这种综合征的患者进行康复治疗时，必须考虑到这些数据。
