Deep Oscillation has been used with excellent results as a rehabilitative therapeutic treatment in patients who contracted the Covid-19 virus as testified by the German Klinik Havelhöhe hospital. COVID-19 patients can often develop pulmonary edema or pulmonary tissue fibrosis as a complication. In these cases, Deep Oscillation therapy can make an important contribution to the healing process. Deep oscillation treatments can slow down or even stop the advancement of fibrosis leading to a decrease in fibrotic adhesion between the lungs and the chest wall.
