Faster Recuperation of Pain and Musculoskeletal System through Vibroacoustic Sound Therapy

Recently, medical doctors and biotechnology researchers from various countries have developed new therapeutic methods and techniques called vibroacoustic sound therapy (VAT) for a wide range of patients. However, most of the patients from previous studies had chronic diseases or were at the latter phases of therapy. Although the effectiveness of VAT has been examined in a few studies, no research has yet been conducted regarding the application of VAT on patients shortly after undergoing an operation on a joint. The aim of this study was to determine the therapeutic effect of applying VAT on pain, range of motion (ROM), and isometric strength in patients who have recently had a knee joint operation. A total of 22 patients who underwent knee joint surgery within the past 7 days were selected for this study and were randomly divided in the control group and the experimental group, which received VAT for 30 min * 5 days/week for 4 weeks. The intensity of VAT was set from minimum to maximum with a wide range of sound waves and patterns of vibration. After 4 weeks of VAT intervention, the hamstrings were shown to have improved more than the quadriceps. Thus, this study confirmed that the recuperation of hamstrings in patients who recently received a knee joint operation may result in reduced pain and increased ROM through VAT intervention.
