Introduction: The term prolapsed disc means the protrusion or extrusion of the nucleus. It is not a onetime phenomenon rather it is a sequence of change in the disc which ultimately leads to its prolapsed. It is a spinal condition that can cause lower back pain as well as numbness, tightness of muscle, pins and needles sensation, and feeling of muscle weakness in the lower body.

Need for Study: There are many researches being done on the effects of core strengthening exercises and McKenzie extension exercise on low back pain separately. I want to compare both of them to derive a better and effective exercise plan for low back pain of lumbar prolapsed intervertebral disc condition.

Methods: 30 subjects were selected and divided into 2 groups randomly. The Group A subject received McKenzie extension exercise The group B subject received Core strengthening exercise. Both the group were treated for 2 weeks. The patients were treated for 6 sessions on a week. Pre intervention measurements for pain intensity using VAS, and functional disability using ODI for low back pain (both groups).

Result: Student t test was used to compare the data of the two groups. The subject’s conditions were similar between the groups, with regard to all variables selected. There was significant difference observed with respect to V.A.S. and O.D.I between McKenzie extension exercise and Core strengthening exercise. Hence McKenzie extension exercise were found to be more effective in comparison to core strengthening.

Conclusion: The present study concluded that McKenzie extension exercise protocol was more effective in comparison to core strengthening in low back pain with PIVD condition.
