Tango-dancing and walking programs are compared in nondemented seniors at risk for falls. Fallers (N = 30) age 62-91 were randomly assigned to a 10-wk (40 hr, 2 hr 2x/wk) tango class or walk group. The Activities-specific Balance Confidence (ABC) scale, sit-to-stand scores, and normal and fast walk were measured pre-, post-, and 1 month postintervention. Two-way repeated-measures ANOVAs indicated a significant main effect (p < .01) for time on all measures. Group and interaction effects for ABC led to improvement only in tango because of high baseline mean for the walk group. Clinical improvements measured using Established Populations for Epidemiologic Studies of the Elderly scoring were greater for the tango group. From these preliminary results it is suggested that although both interventions are effective activities for increasing strength and walk speed, tango might result in greater improvements than walking in balance skills and in walking speed in the 10-wk intervention. The study needs to be repeated with a greater sample size to determine the effectiveness of walking on fear of falling.
在有跌倒风险的非痴呆老年人中对探戈舞蹈和步行计划进行比较。62至91岁的跌倒者(N = 30)被随机分配到为期10周(40小时,每周2次,每次2小时)的探戈课程或步行组。在干预前、干预后和干预后1个月测量特定活动平衡信心(ABC)量表、从坐到站的得分以及正常行走和快速行走情况。双向重复测量方差分析表明,在所有测量指标上,时间的主效应显著(p < .01)。由于步行组的基线均值较高,ABC的组间效应和交互效应仅在探戈组中导致改善。使用老年流行病学研究既定人群评分法测量的临床改善情况,探戈组更大。从这些初步结果表明,虽然两种干预都是增强力量和步行速度的有效活动,但在为期10周的干预中,探戈在平衡技能和步行速度方面可能比步行带来更大的改善。该研究需要以更大的样本量重复进行,以确定步行对跌倒恐惧的有效性。
