"Effectiveness of McKenzie Extension Exercises in Reducing Radiated Low Back Pain: A Quasi-Experimental Comparative Trial"

Background: Low back pain (LBP) is a prevalent condition that significantly impacts individuals' quality of life and daily activities. Radiated low back pain, particularly in acute or sub-acute stages, poses a challenge for effective management. The McKenzie Method, particularly McKenzie extension exercises (MEE), has been suggested as a beneficial intervention for alleviating radiated pain. This study was conducted to evaluate the effectiveness of MEE on radiated low back pain among patients in Iraq.Aim: This study aimed to assess the impact of McKenzie exercises on radiated low back pain in patients with acute or sub-acute low back pain.Methods:The study was conducted at the physiotherapy department of Rzgary Teaching Hospital in Iraq from October 20th, 2021, to March 1st, 2022. A total of 51 patients (26 males and 25 females) with acute or sub-acute radiated low back pain were conveniently sampled. Participants received McKenzie extension exercises as part of their treatment program. Assessments were conducted at 1 week, 3 weeks, and 3 months using a numerical rating scale (NRS) for pain and the Roland-Morris Disability Questionnaire (RMDQ) for disability resulting from low back pain.Results: The study demonstrated significant improvement in radiated pain over the three-month period. The mean radiated pain score decreased from 1.863 at the pretest to 0.235 at three months, indicating substantial improvement. Significant improvements in radiated pain were observed at each assessment point, with p-values less than 0.001. Most participants reported intermittent pain, with bending as the most aggravating factor and lying down as a relieving factor. The sample included participants from various residential areas, predominantly married individuals with a lower educational background. The duration of low back pain among participants varied, indicating a mix of acute and sub-acute cases.Conclusion: The findings suggest that McKenzie extension exercises effectively reduce radiated low back pain in patients with acute or sub-acute conditions. The intervention led to significant improvements in pain and disability over a three-month period. Further research is warranted to explore the long-term effects and potential benefits of McKenzie exercises in centralizing pain.
