of bronchial asthma

Nowadays mathematical methods in
medicine close up with cybernetic and information methods , that allow to
obtain more accurate conclusions and recommendations, introduce new facilities
and treatment modes and diagnostics. Statistical methods of data processing are
widely used by medical persons, it facilitated by that fact that standard
packages of application programmes ensure processing main operations of
statistical data processing.
Asthma is a disease characterized by inflammation of the bronchial tubes. A
primary treatment for asthma is reducing inflammation through medications such
as prednisone, thereby increasing oxygen flow.
Bronchial asthma remains a worldwide
problem. Up to 7-10 % of population in developed countries has asthma. Every 3
minutes 1 1 patient dies in the world due to asthma. Two thirds of patients
with asthma doubles and reasons of this are not known.
One of the most popular statistic
tasks is a task of comparing the results of
examination any indication in different conditions of
measuring(i.e. before and after some influence) or examination control and
experimental group. Moreover, often there is necessity of estimation the nature
of any psychological characteristic in one or in several groups in
different time periods or to detect dynamics
of this characteristic by influence of experimental effect. There are a lot of
statistical methods ,which are called
criterias of differences. These
criterias allow to estimate authenticity of statistical differences between
different characteristics.
First of all it is necessary to select one of statistical criteria. We
should to compare 2 variables from one sample: medical indexes of patients
before and after treatment with the help of audio-video stimulation.
In this case T-Wilcoxon test is used. The Wilcoxon signed-rank test(T - test) is a non-parametric criteria
for the case of two related samples or repeated measurements on a single
sample. The test is named for Frank Wilcoxon. It allows to establish direction
and intensity of changes.
Thereby, comparison of psychological and physiological
indices of bronchial asthma patients
with different types of
diagnosis before and after audio-video stimulation was realized in statistical package
STATGRAPHICS, using T-Wilcoxon test.
At the result of this work
statistical criteria was chosen and realized for analyzing such experimental
medical data as psychological and physiological indices bronchial asthma
patients with different types of diagnosis.
The research was led with help
of T-Wilcoxon test. This method was realized in statistical package
STATGRAPHICS.
According this research, it can be concluded that the greatest changes
after the course of audio-video stimulation was noticed at patients with BAPI diagnosis.
The lowest influence was exerted on patients with PD diagnosis.
For the reason of
derived results was made conclusions about the influence of audio-video
stimulation on patients with different types of bronchial asthma diagnosis:
the greatest changes after the course of audio-video stimulation was noticed at
patients with BAPI
diagnosis. The lowest influence was exerted on patients with PD diagnosis
For realization of this mathematical method I chose such statistical
package as STATGRAPHICS, that perform and explain basic and advanced
statistical functions. This package have statistical advisor, which interprets
derived results, defines important effects or show possible defects of analyzing.
Thereby,
comparison of psychological and physiological indices of bronchial asthma patients.
