The present study found statically significant difference in cervical ROM more in MET group. This could be occurring due to autogenic inhibition 53.
Following a single session of MET to the hamstring muscles, Ballantyne et al 54 observed in their study and concluded that a significant improvement in passive knee bending. Smiths and Fryer 55 reported significant increase in hamstring extensibility after 2 repetition of MET performed after a 2 week period.
However it has been seen that in mechanical neck pain can lead to shorten the muscle length. So, many muscles are found to be shortened. Many studies gave intervention to the upper Trapezius muscle only and that can found effective in reduction of pain intensity and increase in cervical mobility. In our study we took only Upper Trapezius muscle only as is found to be commonly involved. Moreover it is very difficult for the patient to cooperate in stretching intervention of many muscles in short time duration.
This study concluded that Statistically Muscle Energy Technique and Passive Stretching were significant effective but clinically, Muscle Energy Technique was more effective to reduce in pain intensity and to increase the active cervical rotation and active cervical lateral flexion than Passive Stretching for Upper Trapezius Muscle in Neck pain.
This study merely examined the immediate effect and carry over effect of muscle energy technique and passive stretching. A follow up sessions were not included in this study. Present study having large number of sample size (358) which was difficult to treat for neck pain. The intervention was given only to Upper Trapezius muscle.
