Abstract
Background: Chronic nonspecific low back pain (i.e., low back pain of at least 12 weeks’ duration and without a specific cause) is one of the most common health conditions worldwide. Chronic low back pain is highly associated with disability, emotional changes, and work absenteeism.Power lifting has many potential benefits for spinal health, but also has the potential to create or worsen back injuries. Extending or flexing the back muscles against resistance during power lifting may result in a number of injuries, including muscle strain and ligament injury. Currently no randomized studies examining the effect of this method for patient with low back pain have been published so the need of study is to find out the effect of McKenzie extension bias treatment method with that of back strengthening exercises in low back pain. Method: A randomized controlled comparative trial with a 4 weeks treatment period was conducted. 40 consecutive power lifters both male and female between the age group 20-35 years with low back pain and at least 8 weeks duration of symptoms were randomized into two groups: Group A was treated with the McKenzie method and Group B was treated with back strengthening exercises. Oswestry scale and VAS scale was taken pre-treatment and post treatment. Results were recorded at the end of the treatment. Result: The correlation coefficient r= 0.619 is positive therefore there is improvement by using the Back strengthening treatment method in power lifters. The correlation coefficient r= 0.821 is positive and therefore shows more improvement by using McKenzie treatment method. Coefficient of variation of McKenzie treatment method that is 11.9335 is better than coefficient of variation of back strengthening method that is 14.0311 since coefficient of variation of McKenzie is smaller than back strengthening. Conclusion- It was found that both McKenzie treatment method and back strengthening exercises were effective for Low back pain but McKenzie treatment method is more effective than back strengthening method.
