BACKGROUND/OBJECTIVES: Older adults with mild cognitive impairment often exhibit reduced postural control and increased fall risk. As fall-related injuries consume substantial healthcare resources, the development of fall-preventive interventions is of public health relevance. This study aims to investigate the effects of a six-month dance intervention on postural control and fall-related measures in older adults with mild cognitive impairment. METHODS: In this randomized controlled trial, 55 participants were allocated to either an intervention group or a control group. The intervention group performed two 90-min dance training sessions per week for six months, while the control group maintained their usual activities of daily living. Postural control was operationalized via balance performance, which was measured with the Sensory Organization Test and the Limits of Stability Test. Neuromuscular function of the lower extremities was assessed via muscle contraction velocity using tensiomyography. Fear of falling was quantified with the Falls Efficacy Scale, and participants reported fall history over the past year. It was hypothesized that older adults with mild cognitive impairment participating in the six-month dance training would show significantly greater improvements in postural control and fall-related outcomes than those in the control group. RESULTS: A mixed analysis of variance (time × group) revealed no significant improvements in balance performance or neuromuscular function following the dance intervention ( > 0.05). However, several main effects for time were observed in the Sensory Organization Test, Limits of Stability Test, and muscle contraction velocity. Scores on the Falls Efficacy Scale improved significantly in the intervention group, reflecting reduced fear of falling, although only shown by a paired-samples -test (t(23)= 2.276, = 0.032, d = 0.465). CONCLUSIONS: This study did not provide evidence that a six-month dance intervention improves postural or neuromuscular functions. However, it cannot be ruled out that such null findings are related to confounding factors, such as insufficient training specificity or duration. Nonetheless, the fear of falling was significantly reduced in the intervention group, suggesting potential benefits for perceived fall risk in older adults with mild cognitive impairment.
背景/目的:轻度认知障碍的老年人常表现出姿势控制能力下降和跌倒风险增加。由于与跌倒相关的损伤消耗了大量医疗资源,因此开发预防跌倒的干预措施具有公共卫生意义。本研究旨在调查为期六个月的舞蹈干预对轻度认知障碍老年人姿势控制和跌倒相关指标的影响。 方法:在这项随机对照试验中,55名参与者被分配到干预组或对照组。干预组每周进行两次90分钟的舞蹈训练,为期六个月,而对照组维持其日常生活活动。姿势控制通过平衡表现来衡量,使用感觉统合测试和稳定性极限测试进行测量。通过使用张力肌电图测量肌肉收缩速度来评估下肢的神经肌肉功能。用跌倒效能量表对跌倒恐惧进行量化,参与者报告过去一年的跌倒史。研究假设是,参与为期六个月舞蹈训练的轻度认知障碍老年人在姿势控制和跌倒相关结果方面的改善将显著大于对照组。 结果:方差混合分析(时间×组)显示,舞蹈干预后平衡表现或神经肌肉功能无显著改善(>0.05)。然而,在感觉统合测试、稳定性极限测试和肌肉收缩速度方面观察到了几个时间的主效应。干预组的跌倒效能量表得分显著改善,反映出跌倒恐惧降低,尽管仅通过配对样本检验显示(t(23)=2.276,=0.032,d=0.465)。 结论:本研究没有提供证据表明为期六个月的舞蹈干预能改善姿势或神经肌肉功能。然而,不能排除这些无效结果与混杂因素有关,如训练特异性或持续时间不足。尽管如此,干预组的跌倒恐惧显著降低,表明对轻度认知障碍老年人的跌倒风险感知有潜在益处。
