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
Keywords:Chronic Low Back Pain, Interferential Therapy, ODI, VAS, MMT and McKenzie Extension Bias Exercises.
Chronic low back pain is one of the most common musculoskeletal disorders in different age groups in
developing 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% adult
populations face one episode in their life. Chronic low back is a barrier in terms of economic burden in health
care system among various musculoskeletal disorders. Promote and administered a rehabilitative program
necessarily to fix and resolve the problems arising from and with chronic low back pain. The purpose of this
study was to determine the effect of interferential therapy along with McKenzie extension bias exercise on
pain, 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 participated
in this study. After taking written consent form from the patients. Firstly, moist heat pack was implicated
to patient for 15 minutes. The patient asked regularly about the temperature of heat pack and therapist
also monitors the skin texture and suitability towards the procedure. Further implementation, Interferential
therapy was given to lumbar spine for 30 minutes followed by Mckenzie extension bias exercises with 3 sets
of 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 spinal
extensors muscle strength in order to decrease VAS, ODI and increase MMT score respectively with follow
up 4 weeks protocol.
Conclusion- The study concludes that interferential therapy along with McKenzie extension bias exercise
has been positive impact in reducing pain, disability and spinal extensors muscle strength in patients with
chronic low back pain.
