Introduction: Low back pain is an extremely common symptom in the general population   affecting up to 85% and isthe most common disability in those under the age of 45 and the most expensive health problem in those between the ages of 20 to 50. Low back problems have  been identified as the leading cause of disability and absenteeism in the working population
(Goldberg et al., 1980; Haber, 1971; Troup, 1965). Nachemson (1971)  Purpose of the Study: The purpose of the study is to improve the effect of treatment with   pnf stretching and core stabilization control exercise than compared to McKenzie exercises for
improving the low back pain. Methodology: 30 subjects having radiological diagnosis of low back pain were selected  according to the inclusion criteria. Decreasing pain and increasing ROM of the lumbar spine  with the help of VAS and SCHOBER test. The subjects of group A received PNF stretching and  core stabilization exercise and second group B received with mckenzie technique in low back  pain. The post intervention data was compared with pre-intervention data and improvement   of ROM is measured. All the participants were explained about the purpose of study. The   subjects were screened for inclusion and exclusion criteria and then the baseline measurement   was taken. An informed consent was taken from patients who were willing to participate in
the study. Eligible subjects were randomly allocated into two groups of group A received PNF stretching and core stabilization exercise and second group B received with mckenzie technique   in low back pain. The study was of 6 week at department of physiotherapy in SMIH.  Results: A statistically significant  difference in improvement was noted  within the groups and between the  groups   in terms of visual analogue (p0.05)   Conclusion: PNF Stretching with core   stabilization control exercise and mckenzie
technique both shows improvement in low   back pain but Mckenzie technique shows  more improvement in centralizing the pain
and ROM in low back pain after 6 weeks   of therapy.
