简要总结
To determine the efficacy of a dual-task tai ji quan training therapy in reducing the incidence of falls in older adults with mild cognitive impairment.
详细描述
The primary aim of the study is to determine the comparative efficacy of two tai ji quan interventions (Dual-task tai ji quan, standard tai ji quan), relative to a stretching exercise control, in reducing the incidence of falls among community-dwelling older adults with mild cognitive impairment.

研究组 & 干预措施
Dual-task taj ji quan
This intervention includes training of (a) symmetrical postural tai ji quan forms/movements synchronized with breathing, (b) controlled displacement (weight-shifting) of the body's center of mass over the base of support, (c) dynamic eye-hand movements during whole-body motion, (d) multidirectional (anterior-posterior and medial-lateral) stepping, and (e) rotational ankle sway and self-induced reactive postural recovery actions. The training practices are integrated, gradually over time, with a mix of interactive, cognitively stimulating, dual-task exercises that challenge attention control, working memory, verbalization, response inhibition, processing speed, dual tasking, task switching/prioritization, and spatial orientation and postural awareness.
干预措施: dual-task tai ji quan (Behavioral)
Standard tai ji quan
This intervention includes training of tai ji quan forms with synchronized breathing, supplemented by a set of mini-therapeutic exercises. The training involves repeated practice of (a) symmetrical, coordinated, trunk-driven tai ji quan form movements, (b) controlled displacement (weight-shifting) of the body's center of mass over varying sizes of the base of support, (c) dynamic eye-hand movements during whole-body motion, and (d) multidirectional (anterior-posterior and medial-lateral) stepping. As a balance training therapy, movement practices emphasize a dynamic interplay of stabilizing and self-induced destabilizing postural actions and balance exercises that target mobility, stability limits, and sensory integration.
干预措施: standard tai ji quan (Behavioral)
Stretching exercise
This active control intervention includes light activities that consist of breathing, stretching, and relaxation exercises. Each exercise session encompasses a variety of light and static stretches for joints and muscles, performed in a seated or standing position. Exercise involves the upper body (arms, neck, upper back, shoulder, back, and chest), lower extremities (quadriceps, hamstrings/calfs, and hips), and gentle and slow trunk rotations. Also included are intermittent light walking, deep abdominal breathing exercises that emphasize inhaling and exhaling to maximum capacity, and progressive relaxation of major muscle groups.

结局指标
主要结局
Self-reported number of falls
时间窗: Monthly, baseline to 6 months (i.e., after end of intervention)
This measure will reflect change in the incidence of falls as a result of intervention. Study participants will be given a falls calendar to record number of falls at home. Falls are defined as "when you land on the floor or the ground, or fall and hit objects like stairs or pieces of furniture, by accident." This information will be ascertained monthly via a phone call by study assessors
