Assessment of clinical efficacy of the acoustic binaural beating method in the complex preparation of patients for hip replacement

Abstract

Objective. To increase the efficiency of the complex of therapeutic and rehabilitation measures in preparation for hip joint endoprosthetics.
 Materials and methods. 66 patients in whom it was planned to perform hip joint endoprosthetics took part in the research. They were divided into two groups. The main group (n = 32) included patients who underwent 5 binaural beats as a relaxation program. In the comparison group (n = 34) the patients received a standard set of measures to prepare for this operation. All patients were screened for depression and anxiety using the standardized hospital scale for anxiety and depression (HADS) before the study. We also recorded the initial levels of reactive and personality anxiety using the Spielberger Hanin test. We repeated the test in both groups after 7 days to evaluate the dynamics of the test.
 Results. The conducted research showed that in the main group on the background of binaural beating procedures, reactive (from 57.2 3.8 to 42.4 5.2 points, p = 0.014) and personal anxiety (from 58.9 4.1 to 44.7 3.8 points, p = 0.003) were significantly reduced. In addition, the application of binaural beats method resulted in a significant decrease of HADS alarm subscale indexes (p 0.001) in patients of the base group from 12.8 2.8 to 8.5 0.7 points. While patients in the comparison group had significantly less expressed decrease of this parameter from 11.7 3.1 to 10.9 1.6 points (p 0.01). On the HADS depression subscale there was also a marked decrease in the main group to 7.1 0.8 points, this value was statistically significantly lower (p = 0.011) than in the comparison group 10.2 1.2 points.
 Conclusion. The conducted research has shown that the use of the binaural beats method in the complex of measures to prepare patients for hip joint endoprosthetics helps to improve their psycho-emotional status. This is manifested by a decrease in personal and reactive anxiety in the Spielberger Hanin test, as well as the severity of depression and anxiety on the HADS scale. The advantages of the method are non-invasive and easy to use, and the disadvantages include the duration of the procedure and poorly studied mechanism of action.
