The purpose of this study is to evaluate the effects of Massage Therapy for improving the quality of sleep in patients on postoperative period of coronary artery bypass graft surgery (CABG).

Patients We evaluated patients admitted to the ward waiting for elective CABG surgery.

Preoperative evaluation The preoperative clinical assessment consisted of obtaining information regarding demographics and personal characteristics.

Postoperative protocol and evaluation After discharge from the intensive care unit to the ward during the postoperative period, the patients were randomized to 3 nights of sitting for 10 minutes, with no intervention (Control) or to MT. Briefly, MT consisted of massage of the neck, shoulders, and back. The massage was initiated with light manual compression and progressed to deep compression. The compression was performed with the inner region of the fingers, hand-shaped clamp, and friction (digital compression with the thumb) on trigger points, cervical traction, and mobilization in all planes (front, back, and sides). The massage was finished with light manual compression. During the study period, all patients completed a sleep diary containing the time they went to sleep, woke up, and took daytime naps. The patients completed a VAS for pain and fatigue (similar to the preoperative evaluation described previously) as well as a VAS for sleep on days 1, 2, and 3, corresponding to the morning following the intervention that was performed on the previous night.
