Dual-task ExerciseA Study of Dual-task Exercise Training to Prevent Falls Among Older Adults With Mild Cognitive Impairment

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.

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.

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.
