Effects of Lumbar Stabilization Exercises, Mckenzie Exercises and Conventional Exercises on Pain, Function and Range of Motion in Patients with Mechanical Low Back Pain: A Comparative study

OBJECTIVES: To compare the effects of lumbar stabilization exercises, Mckenzie exercises and conventional exercises on pain, function and lumbar range of motion in patients with mechanical low back pain. STUDY DESIGN: Quasi experimental study design. STUDY SETTING: Kovai Medical Centre and Hospital, Coimbatore. SAMPLE SIZE AND INTERVENTION: 21 patients with mechanical low back pain who met the inclusion criteria were selected. The duration of the study was 4 weeks.21 patients diagnosed with mechanical low back pain and age group 20-40 years, both males and females were selected. Patients with pain level between 3 and 7 in the numerical pain rating scale were included. 21 randomly allocated into 3 groups- experimental Group A, experimental group B and control group C of 7 samples each. Group A received an exercise pamphlet comprising of 5 lumbar stabilisation exercises, group B received an exercise pamphlet comprising of 5 Mckenzie exercises and group C received an exercise pamphlet comprising of 5 conventional exercises for mechanical low back pain patients which were to be followed at home. OUTCOME MEASURES: • Pain status. • Functional ability. • Lumbar flexion range of motion. MEASUREMENT TOOLS: • Numerical pain rating scale. • Roland Morris functional disability Questionnaire. • Modified Schober’s test. CONCLUSION: The data were analyzed using paired ‘t’ test and one way ANOVA at 5% level of significance. The results of the study concluded that lumbar stabilization group is better than the Mckenzie group and conventional group in reducing the pain, improving the function and increasing the lumbar flexion range of motion
