Comparison of Integrated Neuromuscular Inhibition Technique versus Myofascial Release of Upper Trapezius on Neck Range of Motion and Dysfunction in Individuals with Nonspecific Neck Pain

Abstract

Background: Nonspecific Neck Pain is caused by assumption of faulty neck posture for prolonged period of time,
resulting in overuse of Upper Trapezius and development of Trigger Points in the muscle. This study evaluated
the effect of Integrated Neuromuscular Inhibition Technique and Myofascial Release of Upper Trapezius on Neck
Range of Motion and Dysfunction in individuals with Nonspecific Neck Pain.
Materials and Method: Based on Inclusion and Exclusion criteria 60 individuals with nonspecific neck pain of age
group 25-40 years were assessed & selected by purposive sampling and informed consent were taken. The subjects
were divided into three groups of 20 each. Group A (Control Group) was given Conventional treatment as Hot
Pack over the Upper Trapezius muscle and Neck mobility exercises. Thereafter Group B (Experimental Group 1)
received Integrated Neuromuscular Inhibition Technique & Conventional treatment and Group C (Experimental
Group 2) subjects were given Myofascial Release & Conventional treatment on Upper Trapezius muscle for total
6 sessions as 3 sessions a week for 2 weeks respectively. Pretest and Post test data for the 3 groups were evaluated
for Neck Range of Motion by using Universal Goniometer and Neck Dysfunction by using Neck Disability Index
respectively. The data was collected, compiled and analyzed.
Results: There were significant differences in pre and post scores of Group B (INIT) and Group C (MFR) when
paired t-test was applied. However, Group A (control group) didn’t show any improvement significantly. When
these groups are compared using unpaired t-test, all showed significant differences. Group B demonstrated more
improvement than Group C and Group A. Whereas, when Group C and Group A were compared, Group C
showed significant improvement than Group A.
Conclusion: The study concluded that Integrated Neuromuscular Inhibition Technique is better than Myofascial
Release on Upper Trapezius muscle in improving Neck Range of Motion and Dysfunction in Individuals with
Nonspecific Neck Pain.
