This study compared differences in balance measures among elderly adults with different degrees of balance impairments under different visual conditions.
This study was conducted on 89 adults (> 60 years) with balance impairments. Subjects were divided into 3 groups based on the initial Tinetti score: low risk of fall (LRF, n=29), moderate risk of fall (MRF, n=30) and high risk of fall (HRF, n=30). Three balance measures-Tinetti, Timed-up and Go (TUG), and Functional Reach-were tested with 2 different visual conditions: eyes open with normal vision (EONV) and eyes open with blurred vision (EOBV). All data were analyzed using repeated measures analysis of variance.
Subjects with EOBV had significantly decreased Tinetti (P < .01 ) and Functional Reach (P < .01 ) scores and increased TUG (P < .01 ) scores regardless of fall group. Subjects in the LRF group performed better in all 3 tests than those in MRF (P < .01 ) and HRF (P < .01 ) groups. Subjects in the MRF group performed better in all 3 tests than those in HRF (P < .01 ). There were significant interactions between vision and risk of falls in Tinetti (P < .01 ) and TUG (P < .01 ) scores. However, there was no significant interaction between vision and risk of falls in Functional Reach (P > .05) scores.
Blurred vision significantly altered all 3 balance measure scores in all risk groups. However, blurred vision had a greater influence on Tinetti and TUG scores than Functional Reach scores in subjects with higher risk of falls.
本研究比较了不同视觉条件下,不同平衡障碍程度的老年人在平衡测量方面的差异。
本研究对89名有平衡障碍的成年人(年龄>60岁)进行。根据初始Tinetti评分将受试者分为3组:低跌倒风险组(LRF,n = 29)、中度跌倒风险组(MRF,n = 30)和高跌倒风险组(HRF,n = 30)。采用两种不同视觉条件对三项平衡指标——Tinetti、定时起立行走测试(TUG)和功能性前伸进行测试:正常视力睁眼(EONV)和模糊视力睁眼(EOBV)。所有数据采用重复测量方差分析。
无论跌倒风险组如何,处于EOBV条件下的受试者Tinetti评分(P < 0.01)和功能性前伸评分(P < 0.01)显著降低,TUG评分(P < 0.01)升高。LRF组受试者在所有三项测试中的表现均优于MRF组(P < 0.01)和HRF组(P < 0.01)。MRF组受试者在所有三项测试中的表现均优于HRF组(P < 0.01)。Tinetti评分(P < 0.01)和TUG评分(P < 0.01)在视力和跌倒风险之间存在显著交互作用。然而,功能性前伸评分在视力和跌倒风险之间不存在显著交互作用(P > 0.05)。
模糊视力显著改变了所有风险组的三项平衡测量指标得分。然而,在跌倒风险较高的受试者中,模糊视力对Tinetti和TUG评分的影响大于功能性前伸评分。
