Effect of Interferential therapy along with McKenzie Extension Bias Exercises on Pain, Disability and Spinal Extensors Muscles Strength among the Patients with Chronic Low Back Pain

Abstract

Chronic low back pain is one of the most common musculoskeletal disorders in different age groups indeveloping countries. Low back pain grows up gradually with other associated symptoms such as disability,muscular weakness and functional limitation that restrict the social and overall health wellbeing. 70% adultpopulations face one episode in their life. Chronic low back is a barrier in terms of economic burden in healthcare system among various musculoskeletal disorders. Promote and administered a rehabilitative programnecessarily to fix and resolve the problems arising from and with chronic low back pain. The purpose of thisstudy was to determine the effect of interferential therapy along with McKenzie extension bias exercise onpain, disability and spinal extensors muscle strength in patients with chronic low back pain.Methods- 41 patients were recruited in this study but only 24 patients meet the criteria and participatedin this study. After taking written consent form from the patients. Firstly, moist heat pack was implicatedto patient for 15 minutes. The patient asked regularly about the temperature of heat pack and therapistalso monitors the skin texture and suitability towards the procedure. Further implementation, Interferentialtherapy was given to lumbar spine for 30 minutes followed by Mckenzie extension bias exercises with 3 setsof 10 repetitions. This protocol was given for 6 days in a week for 4 weeks.Results- The result of this study shows that there was significant improvement in pain, disability and spinalextensors muscle strength in order to decrease VAS, ODI and increase MMT score respectively with followup 4 weeks protocol.Conclusion- The study concludes that interferential therapy along with McKenzie extension bias exercisehas been positive impact in reducing pain, disability and spinal extensors muscle strength in patients withchronic low back pain.
