Abstract :

Aim: To test the quadratus lumborum muscle strength on professionals sitting with legs crossed on chair.Need Of Study: If an individual habitually adopts such postures then part of the body will deviate from proper alignment and deformation will be aggravated to compensate for the unstable state causing problems in the musculoskeletal system.Sitting for a long time causes continuous contraction or tightening of the quadratus lumborum muscle which can lead to stretch weakness of the muscle. Constant contraction can lead to muscle fatigue and also lead to its stiffness and pain(15) thereby giving a reason to assess the strength of the quadratus lumborum muscle.Therefore the purpose of this study is to check its effect on quadratus lumborum muscle.Design: Observational. Procedure: The study was approved by the relevant Research and Ethical Committee. Eligible subjects were approached during their free time. All the subjects were explained about the test and informed written consent was taken from all the included subjects.All the subjects were screened for the inclusion and exclusion criteria.A demonstration of the test was given first on a firm surface and subjects allowed to practise once. The subjects were then informed about holding the position to grade them accordingly.The test was then performed and documented. Result:The study is not statistically significant but is clinically significant. 36% of the population had grade 5 strength, 29% had grade 4 strength, 21% had grade 3 strength and 14% had grade 2 strength. Also, 52% population belonged to 20 to 25 age group, 45% belonged to 26 to 30 age group and 3 % belonged to 31 to 35 age group. Conclusion: The study concludes that majority of the professional people who sit with their legs crossed on chair had the quadratus lumborum muscle strength of grade 5.
