The Efectiveness of Mckenzie Exercise in Reducing Pain Among Patients with Low Back Pain in Grandmed hospital Lubuk Pakam

Background: Low back pain (LBP) is a common musculoskeletal issue that frequently results in pain and makes daily tasks difficult. Both pharmaceutical and non-pharmacological treatments are used in the management of LBP. McKenzie exercises are a type of therapeutic exercise that helps individuals with low back pain (LBP) feel less discomfort. The purpose of this study was to evaluate the efficacy of McKenzie exercises in lowering LBP patients' pain levels. Methods: In this quantitative analysis, pretest-posttest control groups and a randomized controlled trial (RCT) design were used. The sample consisted of 62 LBP patients from Grandmed Hospital Lubuk Pakam; 31 respondents were assigned to the intervention group and 31 to the control group. The intervention group received twenty-minute McKenzie exercises three times a week for two weeks. McKenzie exercises were not provided to the control group. To gage the degree of pain, the Numeric Pain Rating Scale (NPRS) was employed. The Mann-Whitney and Wilcoxon tests were employed to evaluate the data. Results: The intervention group's median pain intensity decreases from 7 to 6, while the control group's remains at 7. The Mann-Whitney test indicates a significant difference between the intervention and control groups with an impact size of -0.539 (p=0.001; p<0.05). In conclusion: McKenzie exercises are an excellent way for persons with low back pain to lessen the severity of their pain. McKenzie exercises are one non-pharmacological nursing method for helping patients with LBP manage their pain.
