5.8.16 THE TREND OF DURATION PER CYCLE WITH TIME
Duration per cycle is the TTH pain duration in minutes per frequency (cycle) per week. The average
TTH duration per cycle was as follows (Fig. 5.23):

FIG. 5.23
Analysis of TTH duration per cycle per time.
GSRav: The rate of reduction of TTH pain duration per cycle was tremendously increased when the
therapy of the subject was started between 1 and 3months, then it slowed down in the next 6months and
became stagnant until the end of the experiment. The average reduction in TTH duration per cycle
changed from 112.36 to 70.53min, i.e., 41.83min of improvement was recorded per cycle per subject.
EMGav: EMGa showed similar results but the improvement rate was continuous in nature from
start to end. This technique/therapy reduces the overall TTH duration per cycle from 105.22 to
86.25min per cycle per subject, i.e., an overall improvement of TTH duration per cycle of
18.97min per subject.
From the above analysis, we can conclude that GSRav showed better overall improvement in the
reduction of TTH duration per cycle per subject when compared to the EMGav results. But the rate of
improvement in TTH duration per cycle using GSRav in the last 6months was nearly stagnant and in
the case of EMGav, the rate of improvement was slowly decreasing, which diminished the probability
of further reductions. Therefore, in the longer run, EMGav will be not as beneficial as GSRav.

5.8.17 TREND ON CORRELATION OF TTH DURATION AND INTENSITY
This analysis was performed to establish the relationship of duration of TTH pain with the intensity of
pain. Chronic intensity pain generally stays for a longer duration. Fig. 5.24 reveals the interesting anal-
ysis of subjects’ TTH pain duration correlation with TTH pain intensity. The trends observed are as
follows:
