5.8.9 THE TREND OF AVERAGE OF INTENSITY
GSRv: The rate of average intensity reduction over a period varied alternatively in alternate periods.
In the first duration of 1month, the rate of decrease in intensity of TTH was steep but became nearly
stagnant in the later period (1–12months), until the end (Fig. 5.16).

Variation of average intensity with time.
Similarly, it gradually fluctuated with the time period. The average TTH intensity per week of
subjects decreased from 6.448 to 1.9units/week, i.e., only 4.548units/week.
EMGv: On the contrary, EMGv showed a better improvement rate in reduction of TTH intensity in
subjects. It helped to reduce the intensity from 7.536 to 2.5units/week, i.e., overall improvement
