Correlation Analysis Between Oswestry Disability Questionnaire and Abdominal Flexor Endurance among Non-Specific Low Back Pain Patients

Abstract

Introduction: Forensic ergonomics plays a vital role in understanding the vital relationship between legal problems and injuries. Core stability has an important role to play for an efficient functioning of both the upper and lower limb along with the task of stabilizing the trunk and maintaining proper posture, through a coordinated and integrated manner. The inadequacy of the core poses a risk for the development of low back pain and dysfunction as a result of poor ergonomic posture. The reason has been attributed to an altered neuromuscular balance leading to an imbalance of the endurance of the trunk muscles. Aim: To study the relation between flexor muscle endurance and non specific low back pain. Materials and Method: 6 subjects (3 males and 3 females) were selected on the basis of Oswestry disability index (ODI) questionnaire score of the age group of 22–45 years with a non specific origin of low back pain. The flexor muscle endurance times were noted using the McGill’s flexor endurance test for each of them. A Pearson’s correlation coefficient was then calculated and significance of the testwas determined. Results:The study revealed a Pearson’s correlation coefficient r = 0.622, and a t-test value p-0.001, implying a significant result. Conclusion: It can be concluded that there is a moderate correlation between flexor muscle endurance and non specific low back pain with a revelatory result and it can be utilized for clinical use, such as work ergonomics in an efficacious manner
