Poor postural balance is one of the major risk factors for falling in normal pressure hydrocephalus (NPH). Postural instability in the clinic is commonly assessed based upon force platform posturography. In this study we focused on the identification of changes in sway characteristics while standing quiet in patients with NPH before and after shunt implantation. Postural sway area and sway radius were analyzed in a group of 9 patients and 46 controls of both genders. Subject's spontaneous sway was recorded while standing quiet on a force platform for 30-60 s, with eyes open and then closed. Both analyzed sway descriptors identified between-group differences and also an effect of shunt implantation in the NPH group. Sway radius and sway area in patients exhibited very high values compared with those in the control group. Importantly, the effect of eyesight in patients was not observed before shunt implantation and reappeared after the surgical treatment. The study documents that static force platform posturography may be a reliable measure of postural control improvement due to shunt surgery.
姿势平衡不良是正常压力脑积水（NPH）患者跌倒的主要危险因素之一。临床上通常基于力台姿势描记术评估姿势不稳定。在这项研究中，我们专注于在分流植入前后识别 NPH 患者站立时安静时的摆动特征变化。对 9 名患者和 46 名男女对照组的姿势摆动面积和摆动半径进行了分析。在力台上站立 30-60 秒，睁眼和闭眼时，记录受试者的自发摆动。两种分析的摆动描述符均确定了组间差异，并且在 NPH 组中也观察到了分流植入的效果。与对照组相比，患者的摆动半径和摆动面积值非常高。重要的是，在分流植入之前未观察到患者视力的影响，而在手术治疗后又重新出现。该研究表明，由于分流手术，静态力台姿势描记术可能是一种可靠的姿势控制改善措施。
