Comparison of McKenzie Extension v/s William’s Flexion Exercises in Mechanical Back Pain among Medical Students
Keywords:Activities of Daily Living, Exercises, Low Back Pain, Medical students
This study compared the effects of William’s Flexion and McKenzie’s Extension exercises on reducing mechanical back pain in medical students aged 18 to 25. Stress, prolonged study and work hours, poor posture, and physical inactivity are some of the causes of the high prevalence of low back pain in this population.
A total of 30 students were divided into Group A, which performed ‘McKenzie Extension’ exercises, and Group B, which performed ‘William’s Flexion’ exercises, in a rigorous six-month randomized controlled study. The Numeric Pain Rating Scale measured pain levels before and after the exercise intervention. For within-group comparisons, paired sample t-tests were used, and independent t-tests were used for between-group analysis.
Both exercise groups’ pain levels decreased after 3-weeks of consistent home exercises. In contrast to William’s Flexion group, the McKenzie Extension group did, however, have a statistically significant (p<0.05) decrease in low back pain.
McKenzie’s Extension exercises are more effective than William’s Flexion exercises in reducing mechanical back pain in medical students.
