102 CHAPTER 5 CHRONIC TTH ANALYSIS BY EMG AND GSR BIOFEEDBACK

5.6.12 STATISTICAL ANALYSIS
Effect size at 1year inter group analysis. Percentage improvement was calculated by percentage
improvement¼(baseline-monthly scores)/baseline score. This end product was then converted to
percentage by multiplying it by 100. Significance for the results was set at P<.05.
Data Recording and Visualization: Data collection and recording was done through a subject pain
diary and in records in Microsoft Excel and analytics and visualization in Licensed Tableau on its
software version.
Different visuals were used for analysis and representation purposes. The EMG-IR Retrainer was
used to provide EMG BF (Chattanooga Group Inc., United States) and GSR biofeedback Biotrainer
GPF-2000 was used to provide GSR BF (Biotech, India).

5.6.13 HYPOTHESIS
Meditation has a significant effect on mental health and stress management. There is a significant in-
crease in the rate of reduction of the chronic type TTH using guided meditation by EMG and GSR audio
therapy in 12months.

– There is no significant difference in the mental health (stress and chronic type TTH) using EMGa,
EMGv, EMGav, GSRa, GSRv, or GSRav BF therapy.
– There is no significant relationship between stress and EMGa, EMGv, EMGav, GSRa, GSRv, or
GSRav BF therapy.

5.7 DATA COLLECTION PROCEDURE—GUIDED MEDITATION AS PER
FIG. 5.7G
Subjects were given the following instructions by the instructor:
– Adopt any comfortable meditative posture such as padmasana or siddhasan
– Try to follow the given instructions
– Prepare yourself for the practice of meditation
– Keep the head, neck, and spine upright
– Close the eyes and relax the whole body
– Alpha waves are an indicator of a calm, cool and steady, and concentrated mental state. Development
of talent and the innate caliber happens at this stage. Alpha activity of the brain is affected by stress,
anxiety, mood variations, and different environmental factors.
– The pain diary of the subjects was used to record the average intensity, duration, and frequency of
chronic TTH type headache.

5.8 RESULTS, INTERPRETATION AND DISCUSSION
Trend/pattern analysis of groups undergoing EMGav and GSRav therapies over the experiment period
of 12months on the subjects for chronic TTH Type headache for frequency, intensity and duration
parameters.
