Background: Early rehabilitation in patients undergoing cardiac surgery is associated with better functional outcomes. Several resources have been used, such as resistance and aerobic exercises, early mobilization and inspiratory muscle training. Whole body vibration exercises (WBVE) appear as a new approach to these patients.
Purpose: The aim of this study was to determine the safety and feasibility of WBVE following cardiac surgery during the phase I of cardiovascular rehabilitation.
Methods: Fifteen patients undergoing cardiac surgery were submitted to two daily sessions of WBV, starting on the day of ICU discharge. Patients stood with 15° bended knees on the side-alternating oscillating/vibratory platform. The protocol was composed, initially, by three sets of 1 min (per 1 min rest) at 5 Hz and 8 mm peak-to-peak amplitude. From the second day and on, the sessions were improved daily by 1 set, and the frequency by 1 Hz (maximum of seven sets and 9 Hz on the 7th postoperative day). To determine the safety of the exercises, heart rate, blood pressure, respiratory rate, oxygen saturation, Borg scale, and pain were recorded 1 min prior to training, immediately after exercise and 5 min after training. Friedman's test was used for comparison of several sequential measurements. Statistical significance was assumed at p 0.05.
Results: One hundred and twenty-six vibration sessions were performed. There was no need to interrupt any session and no adverse events were recorded. There was a minor reduction in systolic and diastolic blood pressure. Heart rate, respiratory rate, and Borg scale had a slight increase. Oxygen saturation and pain did not alter by WBVE.
Conclusion(s): This study demonstrated the feasibility of WBVE for patients that have undergone cardiac surgery, during the hospital stay. No undesirable clinical effect was reported and in consequence, the WBVE intervention might be considered safe for the studied population.
Implications: The safety and feasibility of whole body vibration exercises in patients that have undergone cardiac surgery may allow the inclusion of this resource in phase I of cardiovascular rehabilitation following cardiac surgery.
