Dance interventions for people with dementia could benefit balance, gait, fall risk, physical activities, cognition, quality of life, social interactions and behavioral and psychological symptoms. This study investigates the impact of dance on balance, confidence, quality of life and well-being of people with dementia. In order to compensate for the lack of control group, our study followed a crossover experimental design: groups were alternately experimental and control. The study consisted in 12 weekly sessions of dance followed by 12 weeks with no dance activity or conversely. Quantitative and qualitative data were collected. Methodological issues, among which experimental design and outcome measures, did not enable to confirm primary hypotheses. However, quantitative and qualitative data collected during the study enabled us to investigate further effects of our intervention. Results enabled to develop new postulates concerning dance interventions for people with dementia and to contribute to the theoretical and clinical corpus of dance interventions for people with dementia.

对痴呆症患者的舞蹈干预可以有益于平衡，步态，跌倒风险，体育锻炼，认知，生活质量，社交互动以及行为和心理症状。这项研究调查了舞蹈对痴呆症患者平衡，自信心，生活质量和幸福感的影响。为了弥补对照组的不足，我们的研究遵循交叉实验设计：组交替进行实验和对照组。这项研究包括12周的舞蹈课，然后是12周没有舞蹈的活动，或者相反。收集定量和定性数据。方法论问题，其中包括实验设计和结果测量，无法证实主要假设。然而，研究期间收集的定量和定性数据使我们能够调查干预措施的进一步影响。结果使得能够制定有关痴呆症患者的舞蹈干预的新假设，并有助于痴呆症患者的舞蹈干预的理论和临床研究。
