Randomized Controlled Trial
Optimal timing for initiation of biofeedback-assisted relaxation training in hospitalized coronary heart disease patients with sleep disturbances.
Clinical studies have shown that biofeedback-assisted relaxation positively influences the treatment outcomes of sleep disturbance. However, there are only few studies reporting the timing of relaxation training initiation, and the relationships between the timing of initiation and the effectiveness of relaxation remain unclear. ⋯ The timing of the initiation of nurse-led biofeedback-assisted relaxation was 1 of the factors affecting the effectiveness of relaxation. Relaxation training either at night or in the morning-night combination could effectively enhance sleep quality and decrease the need for of sleep medications in hospitalized patients with sleep disturbance.
