Abstract

Purpose: Biodex Balance System (BBS) is a low-cost platform used to assess balance in different populations. However, no study has used this tool to evaluate the risk of falls related to balance changes in non-faller individuals with Parkinson Disease (PD).

Objective: The aim of this study was to determine the changes in the balance in non-faller individuals with mild to moderate PD compared to healthy elders.

Methods: Forty-six PD patients at stages 2 and 3 were assessed in the 'on' state (fully medicated) as well as 31 age-matched healthy controls. They were submitted to the fall risk protocol of BBS and performed three 20-s trials and a 60-s rest interval between the trials.

Results: Non-faller PD patients had an increased instability when compared to the healthy controls in the anteroposterior (controls: 1.54 ± 1.00 vs. PD patients: 2.91 ± 0.93) and mediolateral directions (controls: 1.21 ± 0.57 vs. PD patients: 1.42 ± 0.46), resulting in a great overall instability in the PD patients (controls: 1.28 ± 0.61 vs. PD patients: 4.09 ± 1.22). A significant correlation between overall instability and UPDRS-III (motor symptoms) in individuals with PD was observed.

Conclusion: BBS was able to identify the risk of falls in non-fallers, showing that PD patients have a greater risk of falls in unstable conditions than age-matched healthy elders, mainly due to the large sway in the anteroposterior direction. Furthermore, the severity of motor symptoms was related to overall instability which can increase the risk of falls in PD patients.

使用Biodex平衡系统治疗帕金森病非跌倒患者的跌倒风险

目的:生物指数平衡系统(BBS)是一个低成本的平台，用于评估不同种群的平衡。然而，没有研究使用该工具来评估帕金森病(PD)非跌倒个体与平衡变化相关的跌倒风险。目的:本研究的目的是确定轻度至中度PD患者与健康老年人相比，非跌倒个体的平衡变化。方法:对46例处于“on”状态(完全用药)的2期和3期PD患者以及31例年龄匹配的健康对照进行评估。他们被提交到BBS的跌倒风险方案，并进行了3次20秒的试验，试验之间有60秒的休息间隔。结果:与健康对照组相比，未摔倒的PD患者在正前方(对照组:1.54±1.00,PD患者:2.91±0.93)和中外侧方向(对照组:1.21±0.57,PD患者:1.42±0.46)的不稳定性增加，导致PD患者整体不稳定性较大(对照组:1.28±0.61,PD患者:4.09±1.22)。观察到PD患者总体不稳定性与UPDRS-III(运动症状)之间存在显著相关性。结论:BBS能够识别非跌倒者的跌倒风险，显示PD患者在不稳定状态下跌倒的风险比年龄匹配的健康老年人更大，主要是由于前后方向的大摇摆。此外，运动症状的严重程度与整体不稳定有关，这可能增加PD患者跌倒的风险。

期刊介绍： Somatosensory & Motor Research publishes original, high-quality papers that encompass the entire range of investigations related to the neural bases for somatic sensation, somatic motor function, somatic motor integration, and modeling thereof. Comprising anatomical, physiological, biochemical, pharmacological, behavioural, and psychophysical studies, Somatosensory & Motor Research covers all facets of the peripheral and central processes underlying cutaneous sensation, and includes studies relating to afferent and efferent mechanisms of deep structures (e.g., viscera, muscle). Studies of motor systems at all levels of the neuraxis are covered, but reports restricted to non-neural aspects of muscle generally would belong in other journals.
