Abstract：
UNASSIGNED: Personalized dance-based movement therapies may improve cognitive and motor function in individuals with mild cognitive impairment (MCI), a precursor to Alzheimer\'s disease. While age- and MCI-related deficits reduce individuals\' abilities to perform dance-like rhythmic movement sequences (RMS)-spatial and temporal modifications to movement-it remains unclear how individuals\' relationships to dance and music affect their ability to perform RMS.
UNASSIGNED: Characterize associations between RMS performance and music or dance relationships, as well as the ability to perceive rhythm and meter (rhythmic proficiency) in adults with and without MCI.
UNASSIGNED: We used wearable inertial sensors to evaluate the ability of 12 young adults (YA; age = 23.9±4.2 years; 9F), 26 older adults without MCI (OA; age = 68.1±8.5 years; 16F), and 18 adults with MCI (MCI; age = 70.8±6.2 years; 10F) to accurately perform spatial, temporal, and spatiotemporal RMS. To quantify self-reported music and dance relationships and rhythmic proficiency, we developed Music (MRQ) and Dance Relationship Questionnaires (DRQ), and a rhythm assessment (RA), respectively. We correlated MRQ, DRQ, and RA scores against RMS performance for each group separately.
UNASSIGNED: The OA and YA groups exhibited better MRQ and RA scores than the MCI group (p < 0.006). Better MRQ and RA scores were associated with better temporal RMS performance for only the YA and OA groups (r2 = 0.18-0.41; p < 0.045). DRQ scores were not associated with RMS performance in any group.
UNASSIGNED: Cognitive deficits in adults with MCI likely limit the extent to which music relationships or rhythmic proficiency improve the ability to perform temporal aspects of movements performed during dance-based therapies.

摘要：
■基于舞蹈的个性化运动疗法可以改善轻度认知障碍（MCI）患者的认知和运动功能，阿尔茨海默病的先兆.虽然与年龄和MCI相关的缺陷降低了个体执行类似舞蹈的节奏运动序列（RMS）的能力-对运动的空间和时间修改-但尚不清楚个体与舞蹈和音乐的关系如何影响其执行RMS的能力。
■表征RMS表演与音乐或舞蹈关系之间的关联，以及在有和没有MCI的成年人中感知节奏和仪表（节奏熟练程度）的能力。
■我们使用可穿戴惯性传感器评估了12名年轻人的能力（YA；年龄=23.9±4.2岁；9F），26名没有MCI的老年人（OA；年龄=68.1±8.5岁；16F），和18名患有MCI(MCI;年龄=70.8±6.2岁;10F)的成年人，temporal,和时空RMS。为了量化自我报告的音乐和舞蹈关系以及节奏熟练程度，我们开发了音乐(MRQ)和舞蹈关系问卷(DRQ)，和节律评估（RA），分别。我们关联了MRQ，DRQ,和RA得分对每个组的RMS性能分别。
■OA和YA组的MRQ和RA评分优于MCI组（p<0.006）。仅YA和OA组的更好的MRQ和RA评分与更好的时间RMS表现相关(r2=0.18-0.41;p<0.045)。在任何组中，DRQ评分均与RMS表现无关。
■患有MCI的成年人的认知障碍可能会限制音乐关系或节奏熟练程度提高在基于舞蹈的治疗期间执行动作的时间方面的能力的程度。
