目的:周围神经病变扰乱感觉运动系统,在步行相关的运动任务中造成困难,最终,falls.下降导致功能依赖和对医疗保健的依赖,尤其是老年人。我们调查了周围神经病变是否是老年人跌倒的真正危险因素,以及通过姿势描记术量化姿势控制是否有助于识别有跌倒风险的受试者。
方法:将17名患有下肢临床多发性神经病综合征和融合电生理的老年人与14名没有多发性神经病的老年人进行比较。所有参与者都通过定量运动和感觉测试进行了表征,神经心理学评估,和自我问卷。视频眼震描记术和热量测试排除前庭耳蜗功能障碍。为了进一步分析,所有受试者被分层为跌倒和非跌倒.总的来说,28例患者接受了计算机动态姿势描记术进行个人跌倒风险评估。进行回归分析以确定危险因素和预测性姿势造影参数。
结果:神经病是老年人跌倒的独立危险因素,虽然没有观察到年龄的差异,性别,体重,脆弱,DemTect测试,定时\"Up&Go\"测试,与头晕有关的残疾评分。在计算机化动态姿势描记术中,在充满挑战的条件下,跌倒者更频繁地重新获得姿势控制,而节律性体重移位试验显示缺乏前后双向自愿控制。
结论:我们的研究证实周围神经病变是老年人跌倒的危险因素。堕落者经常使用步进来重新获得姿势控制。这种应对运动的自愿控制受到了损害。有必要对这些参数值进行进一步调查,以预测老年人跌倒的风险。
OBJECTIVE: Peripheral neuropathies perturbate the sensorimotor system, causing difficulties in walking-related motor tasks and, eventually, falls. Falls result in functional dependency and reliance on healthcare, especially in older persons. We investigated if peripheral neuropathy is a genuine risk factor for falls in the elderly and if quantification of postural control via posturography is helpful in identifying subjects at risk of falls.
METHODS: Seventeen older persons with a clinical polyneuropathic syndrome of the lower limbs and converging electrophysiology were compared with 14 older persons without polyneuropathy. All participants were characterized via quantitative motor and sensory testing, neuropsychological assessment, and self-questionnaires. Video-nystagmography and caloric test excluded vestibulocochlear dysfunction. For further analysis, all subjects were stratified into fallers and non-fallers. Overall, 28 patients underwent computerized dynamic posturography for individual fall risk assessment. Regression analyses were performed to identify risk factors and predictive posturography parameters.
RESULTS: Neuropathy is an independent risk factor for falls in the elderly, while no differences were observed for age, gender, weight, frailty, DemTect test, timed \"Up & Go\" test, and dizziness-related handicap score. In computerized dynamic posturography, fallers stepped more often to regain postural control in challenging conditions, while the Rhythmic Weight Shift test showed a lack of anterior-posterior bidirectional voluntary control.
CONCLUSIONS: Our study confirms peripheral neuropathy as a risk factor for older persons\' falls. Fallers frequently used stepping to regain postural control. The voluntary control of this coping movement was impaired. Further investigations into these parameters\' value in predicting the risk of falls in the elderly are warranted.
