ABSTRACT

Chronic back pain defined as pain that lasts for 7–12 weeks or may persists beyond the predictable period of restoration. A Randomized controlled trial study was conducted at department of Physiotherapy in Mayo Hospital Lahore. 40 Sample of patients having age group of 20-60 years were placed in two groups. The Williams flexion exercise was applied in first group while McKenzie extension exercise technique was applied in later group for a window of of 4 weeks. The visual analogue scale (VAS) for pain assessment and Oswestery low back pain disability index (OLBPDI) to quantify disability due to low back pain, were used to asses all the patients before and after 4 weeks of physical therapy intervention. Data was scrutinized by SPSS and statistical test was applied at 95% level of significance, results in determination of the efficacy of both treatment regimens, thereafter compared with each other. Comparative study revealed better result in refining pain and dipping physical disability in first group.
