But it has less number of article available for the adult population. For the clinician, the Kraus-Weber Test is made to reduce the assessment time in clinics and easily administer and less time-consuming. Aim & Objective: To determine the inter-rater reliability of the Kraus-weber Test in physiotherapy students. Methods: 426 subjects (59 male and 367 females); ages ranging between 19-22 years, with no previous or present complaints of injury to the back & lower limbs were selected for the study using the purposive sampling technique of sample of convenience. For inter-rater 2 raters were assessed K-W Test in 426 subjects. All raters were blinded to the procedure. Before collecting the data, training to each rater was given for the administration of the K-W Test. Results: For reliability, ICC has been checked and for responsiveness & distribution based method, SEM & SRD has been analyzed. The K-W Test shows good inter-rater reliability by ICC value. ICC of inter-rater reliability for (A+), (A-) & (FL) is 1, for (P) is 0.998, for (UB) is 0.999 and for (LB) is 0.999. SEM value for inter-rater also finds & it shows there is less error that has been detected in all 2 raters. Conclusion: K-W Test is very reliable tool to access fitness in physiotherapy students.

It is a source of disability that is extremely prevalent and stressful. It is common for all age groups, with the normal exception of infancy and adolescence [2] . A previous study has shown that 70% to 80% of the population in their lifetime had at least 1 episode of low back pain [3-10] . Though, the exact cause of mechanical LBP has not yet been identified due to its negative connection with social and work-related activities [5] . Several studies have attempted to identify & assess the contribution of various demographic, physical, social, psychological & occupational factors to spinal pain production. Ironically, 37% of LBP worldwide is due to occupational risk factors, which are many potentially preventable causes of pain [7] . However, contradictory findings have been documented in the literature with the implementation of different designs & testing procedures [5] . The development of LBP was correlated with several factors, based on observations, clinical results, and scientific experiments. One major theory has long speculated that changes in the size of the lumbar lordosis are the main cause of LBP [5] . Lumbar lordosis is mainly due to the following muscle problems: Abdominal Based on the anatomical location and abdominal muscle activity, it was hypothesized that abdominal muscle weakness causes an anterior pelvic tilt and lumbar hyperlordosis, leading to LBP [5] .
