Efficacy of the muscle energy technique versus the strain-counter strain technique on immediate deactivation of myofascial trigger points in upper trapezius muscle
Abstract
Aims and objectives: Thisstudy aimed to check the comparative efficacy of the Muscle Energy
Technique versus the Strain-Counter Strain technique on immediate deactivation of
myofascial trigger points in the upper trapezius muscle. Study design: The study comprised a
comparative analytical design to compare and contrast the two study interventions. Place and
duration of the study: The research was conducted in the Department of Physical therapy,
Allied hospital Faisalabad for 6 months. Patients and methods: Based on inclusion and
exclusion criteria, 40 subjects were enrolled in the study using the convenient sampling
method. The subjects were divided into two groups; group A (n=20) received a single session
of baseline treatment with themuscle energy technique, while group B (n=20)received a single
session of baseline treatment with the strain-counter strain technique. The subjects were
evaluated through the pressure-pain threshold (algometer), Numeric Pain Rating Scale, and
Modified Bournemouth Questionnaire as pre-intervention and post-intervention measuring
tools for pain and functional status. Results: The data was analyzed using SPSS version 17.
Within group analysis showed a significant difference between pre- values and post values of
pressure-pain threshold, Numeric Pain Rating Scale and Modified Bournemouth
Questionnaire in both groups (P<0.05). Between group analysis was done using independent
sample t test. It also showed significant difference (P<0.05) in post mean values between the
two group subjects in all three outcomes. The post-mean values for the strain-counter strain
group were slightly more improved than the Muscle Energy Technique group. Conclusion:
The strain-counter strain technique is found more effective than the Muscle Energy Technique
for immediate deactivation of myofascial trigger points in the upper trapezius muscle.
