A Study to Compare the Effect of Interferential Therapy with Ergonomic Changes Versus Core Strengthening Exercise on Low Back Pain Among Desk job workers: An Experimental study

Abstract

Background: Desk job workers are spending 75% of work hours in high levels of sitting and improper
posture causing pain over the low back region.1 Physical exercise is recommended for reducing low back pain and
it promotes a healthy lifestyle and quality of life for the workers.2
Purpose: The aim of the study was to determine the effect of Interferential therapy with ergonomic changes versus
core strengthening exercises on low back pain among desk job workers.
Materials and Methods: This was an Experimental study and the subjects were chosen from the KH shoe company,
Ranipet. A total of (N=166) subjects participated in this study based on inclusion and exclusion criteria. The level of
disability was assessed by using the Oswestry low back disability questionnaire and range of motion by modified
Schober test and finger to floor test. The strengthening exercise was received by group B for 30 minutes and rest
for 30 seconds. The entire study period was from September 2022 to July 2023.
Result: This study showed clinically significant reduction of low back pain using interferential therapy. Hence, by
the conventional criteria, this difference is considered to be statistically significant P<0.0001.
Conclusion: This study concluded that comparatively the interferential therapy with core strengthening exercise
was more effective than the Interferential therapy with ergonomic changes.
