This study investigated the association between preserved lower-limb muscle strength, dynamic and static postural stability, risk of falling, and fear of falling in polio survivors. We also investigated whether these clinical features differ between polio survivors and healthy controls. This quasi-experimental study enrolled 16 polio survivors (13 underwent a complete-case analysis) and 12 age- and sex-matched healthy controls. Participants were assessed by the manual muscle test, Berg Balance Scale, force platform posturography, and Falls Efficacy Scale. Between-group mean differences with confidence intervals (MD, CI 95%) and Spearman's are reported. Compared to healthy controls, polio survivors presented reduced muscle strength (MD = -13, CI 95% -16 to -9 points), lower dynamic postural stability (MD = -14, CI 95% -19 to -8 points), and increased fear of falling (MD = 14, CI 95% 10-18 points) (all < 0.001). In polio survivors, lower-limb muscle strength was correlated with dynamic ( = 0.760) and static postural stability ( = 0.738-0.351), risk of falling ( = -0.746), and fear of falling ( = -0.432). Dynamic postural stability was correlated with risk of falling ( = -0.841), fear of falling ( = -0.277), and static postural stability ( = -0.869 to -0.435; = -0.361 to -0.200, respectively). Risk and fear of falling were also correlated ( = 0.464). Polio survivors exhibited impaired dynamic postural stability but preserved static stability and increased risk of falling and fear of falling. Preserved lower-limb muscle strength, postural stability, fear of falling, and risk of falling are associated clinical features in this population.
本研究旨在探讨肌少症、动态和静态姿势稳定性、跌倒风险和恐摔程度之间的关联,并分析其在小儿麻痹幸存者中的表现。同时,我们还探讨了这些临床特征是否在小儿麻痹幸存者和健康对照组中存在差异。本准实验研究共纳入 16 名小儿麻痹幸存者(13 名完成了完整病例分析)和 12 名年龄和性别匹配的健康对照组。参与者接受了徒手肌力测试、伯格平衡量表、测力台和跌倒效能量表的评估。报告了组间平均差异(MD,置信区间 95%)和斯皮尔曼相关性( )。与健康对照组相比,小儿麻痹幸存者的肌肉力量较弱(MD=-13,CI 95%:-16 至-9 分),动态姿势稳定性较低(MD=-14,CI 95%:-19 至-8 分),恐摔程度较高(MD=14,CI 95%:10-18 分)(均 < 0.001)。在小儿麻痹幸存者中,下肢肌肉力量与动态( = 0.760)和静态姿势稳定性( = 0.738-0.351)、跌倒风险( = -0.746)和恐摔程度( = -0.432)呈正相关。动态姿势稳定性与跌倒风险( = -0.841)、恐摔程度( = -0.277)和静态姿势稳定性( = -0.869 至-0.435; = -0.361 至-0.200)呈正相关。跌倒风险和恐摔程度也呈正相关( = 0.464)。小儿麻痹幸存者表现出动态姿势稳定性受损,但静态稳定性保持较好,且跌倒风险和恐摔程度增加。在该人群中,保留的下肢肌肉力量、姿势稳定性、恐摔程度和跌倒风险是相关的临床特征。
