Brief Summary

Sternal instability caused by mediastinitis is one of the most feared complications for cardiac surgery team for generating large commitments and functional damages to patients. Biomechanically, the contraction of abdominal muscles such as transverse abdominal, produces forces that result in a "corset-like" action and anterior thoracic cage muscles too may assist in stabilizing the sternum. Thus, strengthening the abdominal muscles might contribute to the recovery of functional aspects. The aim was to evaluate whether contraction and strengthening the abdominal muscles could improve lung function and respiratory muscle strength in patients with sternal instability.

Outcome Measures

Primary Outcomes (1)

  • Improvement of pulmonary function

    Measure of maximal muscles respiratory pressures and spirometry tests

    3 weeks

Secondary Outcomes (2)

Study Arms (1)

Physiotherapy exercises

EXPERIMENTAL

Two strategies of abdominal exercises with and without movement of the upper limbs applied in patients with sternal instability as randomization.

Other: physiotherapy exercises

Interventions

Consisted of trunk stabilization exercises.The exercises were undertaken for 15 minutes every day for tree weeks. Patients were the contract their abdominal muscles with an emphasis on the transverse abdominal. Patients were to contract their abdominal muscles in a supine,sitting and stand up position.

Physiotherapy exercises
