Added effect of strain counter-strain technique on pain & Cervical ROM in students with mechanical neck pain with upper trapezius trigger points. A RCT

Abstract

Objectives

To assess the added effect of Strain Counter-strain (SCS) technique along with conventional treatment on pain & cervical ROM in students with mechanical neck pain with upper trapezius trigger points.

Methods

In this experimental study, forty students with mechanical neck-pain & upper trapezius trigger points were randomly allocated into two groups, control or experimental group. The control group received conventional therapy consist of moist heat, supervised exercises and trapezius stretching and experimental group received Strain Counter-strain technique along with conventional therapy. Treatment was given once a day for 5 days. A numerical rating scale (NRS) was used to measure the intensity of pain, functional disability was assessed using NDI i.e. neck disability index, and cervical ROM was measured with universal goniometer. Data analysis was done on 5th day.

Results

On pre post analysis, NRS, NDI scores and cervical ROM showed a statistically significant improvement in both control and experimental groups (p < 0.0001). However, between group analysis both NRS and NDI scores showed statistically significant improvement in the experimental group (p < 0.0001). The range of motion for cervical flexion (p = 0.3184) and extension (p = 0.3126) was equally improved in both the groups. But, lateral flexion and rotation on both sides were statistically significantly improved in experimental group than in control group (p<0.0001).

Conclusion

Strain counter strain technique along with conventional treatment is effective in relieving pain & improving cervical lateral flexion and rotation ROM in students with mechanical neck pain with upper trapezius trigger points.
