BACKGROUNDKendall’s approach is used to test the muscles strength and todetermine the correct alignment of the muscle fibers. Themajor causes of back pain are work related problem,mechanical stress on muscles and faulty postures, which leadsto core muscle weakness particularly rectus abdominis or maycause DRA. Thus the study aims to identify a causal relationshipbetween low back pain and rectus abdominis muscleweakness using Kendall’s grading scale.STUDY DESIGNCross Sectional StudySAMPLING TECHNIQUENon-probability convenience sampling techniqueMETHODOLOGY142 (men 33.80% and women 66.20%) participants with lowback pain were recruited in the study. The Kendall gradingscale test the strength of muscles of the upper and lowerrectus abdominis muscles among the participants whileself-administered questionnaire was used to identify thenature of the back pain.RESULTSperman’s rho coefficient of correlation was applied to findout the cause effective correlation between the twovariables, result shows no significant cause effective correlationbetween the upper and lower back pain and lowerrectus abdominis muscles weakness (P>0.05) with r= 0.065 andr=0.031respectively.CONCLUSIONAlthough core muscle weaknesses are the source of backpain but no significant cause effective correlation existbetween the two variables in this study.
