CORRELATION OF TRUNK EXTENSORS ENDURANCE WITH PAIN AND DISABILITY IN PATIENTS WITH NON RADIATING CHRONIC LOW BACK PAIN

Objective: To find out the prevalence and magnitude of relationship between trunk extensors endurance, pain and disability in non radiating chronic low back pain (CLBP). Study design: Cross sectional study and correlation design. Methods: 40 patients (30 males and 10 females) with CLBP were selected from physiotherapy clinics who met the selection criteria. Trunk extensor muscles endurance, pain (TEE) and disability were measured using Sorensen test, visual analogue (VAS) and modified oswestry disability questionnaire (MODQ) respectively. Correlation between variables was measured using Pearson’s correlation coefficient test using SPSS (21 version). Significance level was set at p d” 0.05. Results: TEE has strong negative correlation with VAS (r -0.627) and very strong negative correlation with MODQ (r -0.778). There was strong positive correlation between VAS and MODQ (r 0.696). All values were significant at p d” 0.01. Conclusion: Results of present study indicate that trunk extensors muscular endurance has negative influence over pain and disability in patients suffering from CLBP.
